5 ways to remove an artificial crown from a tooth

June 15, 2019

Many patients are interested in the question of how to remove a crown from a tooth, because essentially the structure is permanent. However, this just means that the owner himself cannot remove it from the mouth, but the dentist, using tools and specialized equipment, will do this without difficulty. Today you will learn about how this process goes, by what methods the final result is achieved, what nuances await patients during the procedure of removing a crown from a tooth from an article prepared by journalists from the editorial office of the UltraSmile.ru portal.

What are the ways to remove a crown?

When is it necessary to remove a crown from a tooth?

Removing the crown from a tooth needs to be done only when there is a serious need for it, because the crown itself can be used for 7-10 years or more (the time period depends on the material from which the prosthesis was made).

Let us list the reasons why it is necessary to resort to such manipulation:

• a disease has developed under the structure: for example, secondary caries, periodontitis or a cyst,
• errors made at one of the stages of prosthetics: perhaps the crown does not correspond to the individual characteristics of the patient, is poorly installed and adjusted, is made of low-quality materials,
• the patient’s desire to replace the structure with a prosthesis made of a better and more beautiful material: for example, replace a metal or metal-plastic product with metal ceramics or zirconium dioxide,
• injuries that led to damage and breakage of an artificial tooth,
• destruction of permanent cement on which the orthopedic structure was fixed,
• The product has expired.

The reason for removal may be the development of caries under the crown.
If the tooth under the crown hurts, there is a bad smell, and the structure has become shaky and movable, then it is time to visit a dentist, who, based on an examination and x-ray, will decide on the need to remove and replace the artificial material.

According to numerous studies, the need to prematurely remove crowns already in the first years of use in 40% of all cases arises due to the fact that poor-quality endodontic treatment and poor-quality sanitation of the oral cavity were performed before preparing for prosthetics.

All of the above reasons are a serious reason to think about removing the prosthetic structure. Naturally, first you need to go to an appointment with a dentist, who will explain how crowns are removed from teeth. And we will look at the methods that exist today.

Treatment

Any type of crown has its own service life, so it is necessary to look at the problem sensibly when pain under a structure made of metal by stamping occurs after 13-17 years of regular wear.

This means that you should not place your hopes on the fact that over all these years the tooth under the microprosthesis has remained healthy and will not bother its owner.

The situation changes if the tooth under the structure “alarms” immediately after prosthetics

It is important to recognize the true cause of what is happening here.

Identifying the problem on your own is quite problematic, so you should completely rely on the integrity and professionalism of your dentist. He will conduct a consultation, prescribe pictures of the jaw and identify the provocateur of painful sensations.

An experienced dentist will find the causative factors of pain and draw up a treatment plan for the unit. In an extremely critical situation, the damaged bone organ is removed, and a secondary prosthetic plan is drawn up according to a new scheme using updated data.

The most optimal method of therapy before treatment and preventive measures to improve the health of the oral cavity involves removing the crown. However, it is unwise to reinstall the same structure, since when removed it is subject to irreversible deformation.

Today, doctors everywhere use a number of methods to relieve the patient of pain under the dental structure without removing it.

Treatment of a living tooth

In such a situation, the pain syndrome is acute. The unit reacts painfully to hot and cold exposure. This indicates the presence of a carious lesion.

The specialist drills a hole in the structure and removes damaged tissue. An artificial hole is made on the chewing side of the tooth, and after treatment it is filled with filling material.

Treatment of a tooth without a nerve

If the unit was previously depulped, the patient will experience aching pain accompanied by pulsation in the temporal region and ear.

This condition is diagnosed as chronic periodontitis (long-term inflammation of periodontal tissues due to infection). Treatment methods are determined depending on the presence or absence of a pin in the root canal:

1. The canal is closed only with a filling.
   The doctor opens the crown, removes the filling material from the canal and cleans it. Next, the tooth cavity is filled with the drug. This procedure usually requires several visits to the doctor. As soon as the signs of inflammation completely disappear, the dental unit is filled.
2. A pin is installed in the channel.
   Under such circumstances, treatment of periodontitis is carried out using apicoectomy (surgery to remove the apex of the root). This is the only effective technique in this case, which involves amputation of the affected area of ​​the root with subsequent blocking of the infectious process. A simple surgical procedure is performed through an incision in the gum tissue.

Inflammation of the gums around the denture

This painful manifestation is often caused by deformation of the microprosthesis or its incorrect installation.

In such cases, a specialist will temporarily eliminate the symptoms. After some time, the pain returns again, so the denture will have to be removed and the tooth may need to be removed.

Is it possible to install ceramic crowns on chewing teeth, and what is the service life of the products?

In this article we will tell you when it is indicated to install an inlay in a tooth under a crown.

Method No. 1: sawing with a boron

So, let's figure out whether it is possible to remove a crown with permanent cement.

The method of removal using boron is the oldest and by far the most unaesthetic. This means that after using this tool, the sawn artificial material will only have to be thrown into the trash bin, because it can no longer be used for its intended purpose, that is, it will no longer be possible to re-prosthetize a tooth with it.

The technique is simple, cheap and quite effective, but it must be used by a doctor who has a high level of professionalism, because the approach requires caution and precision. An inexperienced specialist may damage the tooth itself or the soft tissue around it during the dismantling process.

With this method, it will not be possible to reuse the crown

“We removed the crown from the tooth with a regular bur and simply sawed it in half. There’s nothing terrible, but when the material got very hot, the smell, I’ll tell you, was not very good, plus there were slightly painful and uncomfortable sensations, even despite the fact that I had been given anesthesia before this, and the tooth itself had been under the prosthesis for a long time depulped!"

Mari, review from 32top.ru

This method is used if the patient has dentures made of inexpensive materials, which he would not mind disposing of later. The method is also suitable if the artificial structure itself is mobile or wobbly. Then it is simply sawed to the teeth, then, using special tools, the resulting edges are carefully bent in different directions and removed.

Method No. 2: using ultrasound

Are you wondering how to remove a crown from permanent cement in one of the safest and most innovative ways, and without causing any damage to it? Then ask your dentist if it is possible to use ultrasound in your case. Through impulses, the doctor acts on the cement composition, which gradually cracks. The specialist moves along the “tooth-crown” boundary; under the influence of vibrations, the cement is destroyed.

The product can be removed using ultrasound

The procedure really allows you to remove the structure in its original form, but it has a number of disadvantages. First, ultrasound has a rather gentle effect, so it is not always possible to achieve the goal the first time, and sometimes you have to visit the doctor several times. Secondly, only products that are made from not very dense materials are amenable to hardware exposure to sound waves. For example, it will not be possible to remove structures made using glass ionomers using ultrasound. Third, vibrations may be unpleasant for the patient.

About metal ceramics

Metal-ceramic crowns are prostheses used to restore missing or severely damaged teeth and preserved roots. They consist of two elements: a solid metal frame and an outer part made of ceramic. The base can be made of different metals and alloys, for example, titanium, chromium and nickel, or even gold and palladium. In appearance, a ceramic onlay is practically indistinguishable from a real tooth, as it accurately replicates its color, transparency and texture. The listed properties are selected for each patient individually.

Dental restoration with this prosthetic method is recommended for patients:

• with brittle teeth;
• who have lost more than 50% of their enamel (due to diseases and their consequences);
• with tooth decay that cannot be corrected with conservative methods.

But before choosing this type of prosthetics, pay attention to a few points. Firstly, the tooth on which it is put on needs to be ground down. Secondly, the presence of metal in the structure can lead to the formation of a dark stripe in the gingival area.

Method No. 4: Kop (Koch) apparatus

This is a tool that again has a hook at the end. However, the device is not launched mechanically, but using a button, which breaks the cement along the edge of the crown using small shocks or a shock wave, after which the structure begins to move from its place. Next, the doctor can only use special forceps that hook and help to finally remove the prosthesis.

See what the Koch apparatus for removing crowns looks like in the photo.

This is what the Koch apparatus for removing crowns looks like

This device is more convenient and efficient than a manual device; it allows you to remove the product with virtually no damage and “works” quickly. However, it also has disadvantages. In particular, many patients note that during the procedures they feel “twitching” and discomfort. Also, some people are very concerned about the noise that the device makes. There is one more drawback - the device can damage the ceramic coating of the crown, leaving chips and cracks, and then the structure will have to be restored.

Indications

Prosthetics with crowns is a labor-intensive and time-consuming procedure, sometimes accompanied by pain and discomfort.

To remove the structure, the specialist must have compelling reasons, otherwise he will do everything possible to avoid extreme measures.

A fixed orthopedic device is subject to disposal in the following cases:

• Incorrect installation of the product. The crown may lose stability due to mistakes made by the doctor during its installation, the use of low-quality dental cement, or the destruction of the filling connecting material at the junction points.

It is easy to recognize such a problem, since the dental unit begins to loosen and cause discomfort during eating and conversation.

Formation of a cyst on a tooth under a denture. This pathology rarely occurs as a result of various provocateurs. After removing the structure, the specialist removes the abnormal cavity and carries out full treatment.

Destruction of an adjacent tooth. Another indication for re-prosthetics. In such a situation, the doctor advises installing a bridge instead of two adjacent prostheses.

The appearance of a bad odor and toothache. In this case, there is an urgent need for treatment hidden under the structure of the teeth.

Signs of the inflammatory process can develop against the background of the action of infectious agents, progression of pulpitis or secondary caries. In less severe situations, the doctor does not remove the prosthesis, but drills a small hole in it through which he carries out therapeutic treatment.

After all the necessary manipulations have been carried out, the hole is filled with cement. Such work significantly reduces the service life of the structure. Inflammatory processes in the periodental tissues and gum disease. Disease processes in periodontal tissues can develop due to various factors - inflammation, trauma, poor-quality manufacturing and fixation of the product.

The structure puts strong pressure on the free gum, rubs, and a serious pathology begins to develop that cannot be treated independently. The product must be removed with subsequent treatment of soft structures.

Repeated prosthetics at the request of the patient. The patient can independently decide to replace the device with a more expensive and high-quality product.

Broken prosthesis. The appearance of cracks and chips on the surface of the crown is also a reason for its dismantling.

Method No. 5: using the Coronaflex device

The device looks like a pistol, and its operating principle is based on compressed air, which escapes from the device under pressure and breaks the cement. At the same time, this device does not have any negative effect on the artificial material of the structure or on the soft tissues of the patient.

The Coronaflex device is not available in every dentist today, so the procedure with it will be more expensive compared to other methods. However, it makes sense to use the device if you have a zirconium dioxide crown, which can be reinstalled after, for example, the tooth under the structure is cured. In addition, the procedure using this device is more comfortable, safer, and requires less time to solve the problem. Also, according to patient reviews, the device makes virtually no noise, which allows you to feel comfortable in the dentist’s chair.

The Coronaflex device removes the crown quite comfortably

Crown removal methods

You can remove an installed crown using different methods. It all depends on the purpose of dismantling and therapeutic indications.

The method of removing the prosthesis is chosen by the patient himself based on financial circumstances, available time and recommendations of the dentist. The doctor ultimately chooses the method that is most suitable for the patient, depending on the causes and sensitivity of the teeth during repeated intervention.

Copp (Koch) apparatus

This is a special drill that breaks up the cement base with small pushes. The denture begins to slowly move to the side, leaving the tooth area.

Then, using dental forceps and attachments, the prosthesis is picked up and picked out. The method is painless and does not damage the oral cavity as a whole.

This method has a drawback - the device often scratches the ceramic lining of the prosthesis, which requires its restoration.

Coronaflex device

The device is used to preserve the integrity of the crown during subsequent fixation without injury or damage by exposure to compressed air. The orthopedic structure is preserved and removed without damage.

For example, a product made of zirconium dioxide has a high cost, and it is expensive to damage such a product; it is more economical to use the Coronaflex device. The technique is expensive due to the high price of the equipment used.

Ultrasound de-cementation of the crown

Removal by destroying the cement base. Not all materials lend themselves to this method; it all depends on the type of cemented material. The method is not applicable to glass ionomer substances.

Sawing

This is the crudest technique for items made from durable materials, such as ceramics. The cost is not expensive and almost painless, but quite lengthy. When the prosthesis is removed, it is completely destroyed.

This method is used most effectively if a metal-ceramic crown is loose. As a result of such manipulation, subsequent prosthetics with this structure are no longer possible due to its damage.

Therefore, patients should take this fact into account when choosing a material. When metal-ceramic crowns are removed, pre-treatment with ultrasound is most often carried out, which causes cracking of the cement base and makes it possible to easily remove it.

Other methods

Other methods suitable for dismantling orthopedic structures. To remove them, special tools are used that allow you to control the force and direction of the load on tissue covers and prostheses, namely:

• Higa bridge remover;
• crown removers Metallift and Auto Abdicator;
• special purpose forceps;
• tool with a hooked end;
• jackhammer;
• pneumatic tools.

All techniques are performed under local anesthesia, so pain and discomfort are excluded.

Is it possible to remove a crown at home?

If you are interested in the question of how to remove a crown from a tooth at home, then the answer will be clear: you cannot do this at home. This procedure should only be performed by a professional dentist. For those who neglect this rule, everything can end sadly: there is a risk of damaging not only the artificial material, but also injuring the soft tissues and the tooth itself, which is located under the crown.

You can try to remove the structure yourself only if it has come unstuck and started to loosen, or if it has fallen apart or split, and there is a need to remove the remaining fragments of the product, which can injure the mucous membrane or antagonist teeth. But it’s better if you rush to see a dentist even in such situations.

If the structure comes unstuck, you can remove it yourself

If the materials from which the crown was created, as well as the cement, have expired, and you do not rush to the dentist, then an unpleasant situation may await you. For example, artificial material can be swallowed. What to do in such situations, read the material “5 useful tips for those who have swallowed a crown.”

Possibilities of dental cement

Glue for crowns makes it possible to tightly attach the crown to the root socket and prevent it from falling out of the gums. You can buy such material in specialized stores or at a pharmacy. Each dentist prefers to use a mass familiar to him, from a certain manufacturer. It must be said that if you buy inexpensive material, you can’t hope for a positive result.

Crown adhesive allows you to:

• firmly attach the crown to the tooth socket and thereby hold it during chewing movements;
• prevent the process of tooth decay from the inside;
• create a durable protective coating that will prevent bacteria from entering the tooth.

Recommendations from experts on the selection and use of dental glue

In case of severe tooth decay, when treatment is simply impossible, crowns are used. This fixed prosthesis accurately imitates a lost tooth and performs all its functions.

Before installing a crown, the damaged tooth is ground down and then special dental cement is applied. This material allows you to firmly attach the crown and not move during the chewing process. This material, after hardening, becomes very durable.

A prosthesis fixed with such a mass can serve a person for more than 10 years without causing any inconvenience to the person - an unpleasant smell or taste.

Even if you buy the strongest adhesive, this does not guarantee that the cement will withstand even the most intense and severe loads. Very often, a crown can fall off at the most inopportune moment, and then you need to immediately contact your dentist. When this is not possible, you can fix the problem at home.

Is it possible to cure a tooth without removing the crown?

The question is very relevant, because usually, after removing a structure, it can rarely be reused for its intended purpose, therefore, you have to pay money for the manufacture and installation of a new prosthesis. Fortunately, today in some cases you can do without removing the structure. For example, if it is necessary to cure recurrent caries or remove a small cyst, the doctor may perform endodontic manipulations through a small hole made in the crown or through an incision in the gum (to remove the cyst). After the procedures, this hole will be masked with a composite material, and the sutured gum will need time to heal.

In some cases, modern technologies make it possible to cure a tooth without removing the crown.

However, you need to understand that in order to safely and effectively carry out such jewelry manipulations, the doctor must be a professional. In addition, the patient himself should seek help when the problem is still minor and the inflammatory process has not gone too far. To do this, it is necessary to undergo preventive examinations, because the more minor the problem, the easier it is to solve it with therapeutic methods, without resorting to drastic measures.

crown

1. Lutskaya I.K., Zinovenko O.G. Frequency of development of caries in teeth covered with artificial crowns.

Following actions

After removal of the orthopedic product, the patient may experience discomfort and pain.

To identify the cause of pain, a specialist examines the condition of the tooth. In some cases, radiography is performed for an accurate diagnosis.

The doctor’s algorithm for further actions will depend on the situation as a result of which the crown had to be removed:

Treatment of the inflammatory process. In the presence of diseases such as pulpitis, caries and periodontitis, the root canals of the tooth are unfilled. Next, the doctor’s task is to prevent the pathological process in tissues using anti-inflammatory therapy. At the last stage of treatment, a filling is installed.

Restoration. To prevent subsequent destruction of the crown if it is damaged or chipped, restoration measures are required.

Replacement of cement when it is destroyed

Here it is important to quickly treat the stump with antiseptic agents and re-fix the prosthesis using new dental cement.

Replacement of the structure at the request of the patient or if it is impossible to reuse it. Using an x-ray, the doctor evaluates the quality of dental canal filling, as well as the condition of the periodontal structures.

After this, you can select and order a new design.

The therapeutic course of treatment includes the following procedures:

• to fight infection and eliminate inflammation, the patient is prescribed medications from the group of antibiotics;
• Rinsing the mouth with decoctions of medicinal herbs and Furacilin solution is effective;
• To reduce pain, dentists recommend using anti-inflammatory compresses with an analgesic effect.
  A paste made from 1 tablet of Nurofen and a few drops of boiled water has worked well here. It is rubbed into the wound area.

In rare cases, the tissue under the crown becomes permanently damaged and cannot be saved. Under such circumstances, the doctor warns the patient about the extraction of the tooth from the alveolus and the impossibility of re-fixing the crown.

As an alternative, you can choose another prosthetic option or resort to implantation.

Good afternoon. My metal-ceramic bridge on one tooth became movable. It is possible to remove the bridge without damage in order to reuse it. Thank you.

Svetlana (06/18/2019 at 11:25 am) Reply to comment

Dear Svetlana! As a rule, no, the bridge is completely removed (you need to saw it). In addition, it is fixed on at least 2 supporting teeth, which apparently have become unusable.

Tell me, how do you remove the crown from the implant?

AlinaR. (06/22/2019 at 17:29) Reply to comment

Dear Alina! There are two extraction methods here, and which one to use will depend on how the crown is attached to the implant. If the fixation was screw (which is more preferable), then the doctor will simply unscrew the screws connecting the crown, implant and abutment. If the fixation was cement, then the specialist will use the cutting method - others are not suitable for implantation.

Is this procedure, removing a crown from a tooth, painful?

Arfa (07/18/2019 at 04:47 pm) Reply to comment

Good afternoon This procedure cannot be called pleasant and comfortable, but it is painless, because... the doctor applies anesthesia. In addition, in most cases, crowns are used to replace already pulpless teeth that do not have a nerve. Pain and discomfort can only occur if inflammation has begun under the crown. Then pain can be felt not only in the tooth itself, but also in the soft tissues surrounding it.

Will my tooth hurt after the crown is removed?

Vedeneeva Victoria (05.08.2019 at 19:05) Reply to comment

Dear Victoria. A tooth can only hurt if it has developed periodontitis or granuloma. Less often, pain occurs because the crown removal procedure was carried out by a not very professional doctor, who could injure the gums or mucous membranes, or damage the tooth itself.

Tell me, what if the crowns do not fit tightly to the gums on the back side, where is the palate? is this normal? that is, the tricrowns on the right entered the cast gums; three crowns _and the other three on the back side I feel their edges with my tongue….

What is a cermet bridge?

A metal-ceramic bridge is a metal base on which several crowns rest at once. The class of such a prosthesis is non-removable. Thanks to it, you can restore from 1 to 4 teeth. The edges of the bridge are attached to the supporting teeth, and the empty space between them is filled with crowns.

This design has high functionality of artificial teeth and their significant reliability. Such bridges are made by spraying ceramics onto a metal alloy. Metal gives the product strength, and ceramics allows you to make a prosthesis that is as close as possible in color to the shade of enamel on living teeth.

Many dentists recommend their patients to install metal-ceramic bridges because of their high strength, durability, high aesthetics, resistance to dyes and good repairability.

The manufactured material does not cause chemical or allergic reactions, which allows the use of metal-ceramic products for almost every client of the dental clinic.

Let's consider the metals that are used in the manufacture of such products:

1. Alloys of cobalt and chromium with base metals.
2. Semi-precious, for example - zirconium.
3. Precious metals are alloys of gold with palladium or platinum.

An important component for the ability to install a bridge is the presence of two supporting teeth that are able to take on the entire load falling on the bridge. For fastening it is necessary to grind the support teeth

If necessary, they are sometimes sealed or a pin is installed.

In what cases is complex tooth extraction required?

• Inability to cure one of the molars.
• Growth of wisdom teeth at an angle.
• Uncut "eights".
• Curved and severely damaged roots.
• Fusion of roots with jaw bones.

There is also such an operation as complex tooth root removal. Sometimes the tooth is completely destroyed from the outside, but the root remains in the jaw and continues to become inflamed and painful. In this case, the dentist cannot simply pull out the tooth with forceps, since there is nothing for it to grab onto. You have to cut the gum and use special tools.
