Modern solutions offered by clinics allow an individual approach to each patient and selection of the optimal method of restoring teeth in case of their destruction or absence. Prosthetics allows you to restore the aesthetics of the dentition and natural chewing functions, while prolonged absence of teeth always leads to serious health consequences - it affects the bite, jaw joints, and facial appearance. Therefore, it is so important to undergo prosthetics as soon as possible and enjoy the result. But what if instead of “pleasure” you get pain after dental prosthetics?
Reasons for installing a crown
A crown is a kind of cap that is placed on a tooth, covering and protecting its tissue. Installed in three cases:
- If the natural crown of the tooth is destroyed by more than half and it is impossible to restore it with filling material or other restoration methods;
- To improve the aesthetics of the dentition - correct the shape of the tooth, hide visual flaws;
- When using prosthetics using a bridge. In this case, crowns are placed on the supporting teeth.
A crown can only be installed on a tooth with an intact root. If the upper part is significantly destroyed and the carious process has reached the pulp, before installing the crown, the tooth is depulped and the root canals are filled.
When installing a bridge, the supporting teeth are covered with dental crowns, even if they are not destroyed. If the tooth is relatively healthy, the dentin and pulp are not affected, crowns can be installed without depulpation.
Our clinic’s specialists do not recommend that patients install bridges, but offer alternative types of prosthetics if the supporting teeth are healthy. To place a crown, the doctor must prepare (grind) the tooth, that is, completely remove the enamel. Without a natural protective layer, even if covered with a crown, the tooth becomes vulnerable and gradually collapses. A bridge should only be placed on teeth that have “nothing to lose.”
What to do at home?
If a tooth with a crown hurts, then you need to quickly visit a specialist - a dentist. Before visiting a doctor, you can take the following measures:
- Take a pain reliever. It is better to use medications from the group of non-steroidal anti-inflammatory drugs - Paracetamol, Nimesil, Ibuprofen, Tempalgin, Ketanov;
- Carefully carry out hygienic cleaning of teeth and interdental spaces;
- Rinse the mouth with decoctions of medicinal herbs;
- Rinse with a salt-soda solution every 1-2 hours. To prepare the solution, you need to dissolve 1 teaspoon of salt and soda in 200 ml of boiled, slightly cooled water.
Materials for making crowns
Modern dental crowns are made from:
- Metal.
Metal dentures are considered obsolete due to their lack of aesthetics, but are still used because they are the cheapest option; - Metal ceramics.
A relatively inexpensive and durable option, but due to the metal base it is difficult to achieve a “healthy” whiteness of an artificial tooth; - Ceramics.
Ceramic crowns are more aesthetically pleasing than metal-ceramics, but are inferior in strength, so they are usually installed only on the front teeth; - Porcelain.
A type of ceramic crown. Porcelain dentures are indistinguishable from living teeth, since the optical properties of the material are almost identical to tooth enamel. They are also installed on the front teeth; - Zirconia.
They are made on the basis of zirconium dioxide and covered with ceramics on top. Durable, aesthetic, but quite expensive crowns.
Zirconium dentures can be installed on any tooth.
The material, contrary to popular belief, does not cause toothache, but may be the answer to the question of why the gums hurt after installing a crown. Inflammation of the mucous membrane and gums can cause an allergic reaction to the metal in a metal-containing crown. Patients with ceramic and zirconium prostheses do not encounter such problems.

question for a specialist
Several decades ago, “gold” and “iron” bridges gave way to their leading positions to another design - aesthetic and durable. We are familiar with it under the name “metal-ceramic bridge”. In today’s material, we will reveal the most important characteristics of a dental bridge made of metal ceramics – what the structure looks like, its pros and cons, how it is placed and how it is removed from the teeth. We will also dwell on other, no less interesting questions on the topic.
Why can a tooth hurt under a crown?
Toothache can occur for several reasons, most of which are associated with poor preparation of the tooth for the installation of a crown. First of all, these are errors when filling root canals after depulpation.
Causes of inflammation
Inflammation under the crown can cause:
- Insufficient filling of canals. If the canal is not filled with filling material to the top, the empty space is quickly populated by pathogenic microflora. Its waste products cause inflammation.
- Poor obturation (filling of canals). If the doctor was in a hurry or, due to inexperience, did not fill the canals tightly with filling material, bacteria will settle in the resulting pores, which will ultimately cause inflammation. Crown pain may occur months or years later.
- Perforation of the canal wall. Most often this happens when the doctor mechanically expands a canal with an uneven axis with a rasp. For example, in a curved or bent root. In order to properly seal the canals in such roots without breaking through the wall, a specialist needs extensive practical experience. The doctor may also damage the wall when installing the pin. If the hole is immediately closed with a special material, there will be no complications. But if the doctor simply fills the canal without closing the “gap,” problems may arise. The filling material is not completely biocompatible with the periodontium - the connective tissue surrounding the root. If, through the resulting hole, it extends beyond the canal, the periodontium becomes inflamed. A complication of the inflammatory process can be a cyst or granuloma.
- A fragment of an instrument in the canal cavity. Unfortunately, this is a common occurrence. The instrument may break due to improper use technique, and this will be the doctor’s fault. Or due to the physiological characteristics of the root. For example, if it is strongly curved and difficult to pass. In this case, the specialist is not to blame. The main problem in such situations is that it is often impossible to remove the tool fragment from the canal. But no matter why the foreign body ended up in the canal, it can cause inflammation, even if the canal is sealed.
- Pulp burn. This happens when a crown is installed on a living (non-pulpless) tooth. During turning, the specialist must strictly adhere to the protocol. In particular, use water cooling and prevent tissue overheating. If the doctor does not adhere to the protocol and is in a hurry, the dentin overheats from the friction of the bur and “burns” the neurovascular bundle hidden underneath it. As a result, the pulp becomes inflamed, the tooth reacts to cold and hot, and acute pain may occasionally occur, turning into aching pain.
- Poor quality crown installation. For example, the denture does not fit well; there is a gap between the crown and the tooth. Another possible mistake is that the ledge for seating the prosthesis is made too low; the crown puts pressure on the gum and causes inflammation. In this case, the patient may feel that when pressing, the tooth hurts under the crown.
How long does it take to get used to dental bridges?
There are many reasons why people lose their own teeth: neglect of hygiene, poor nutrition, gum disease, general health problems. As a result, few people reach middle age and can boast of a full set of teeth.
Of course, inexpensive prosthetics can practically work a miracle and return a person to the ability to chew food normally and smile from ear to ear. Moreover, externally such teeth cannot be distinguished from real ones. Of course, dentures are an excellent option for losing teeth, so many people think that this is the solution to all “dental” problems: after all, there is nothing left to hurt and fall out. In fact, you will have to first adapt to any structures in the mouth, even the best and perfectly fitted ones. And then take proper care of them. Only in this case will artificial teeth meet all expectations.
This is what experts advise those who have recently installed dentures and are just getting used to them.
Dentists say that it is easiest for a person to get used to fixed and single dentures. Most likely, if everything is done efficiently, a few days will be enough. The situation is more complicated with the so-called “bridges”, and it takes the longest to get used to removable structures.
How to treat a tooth under a crown
Treating prosthetic teeth is difficult and expensive. Inflammation can only be relieved by eliminating its cause. To do this, you need to unseal the canals, carry out anti-inflammatory therapy, which can last 2-3 months, then fill the canals again.
The patient will not only have to endure several unpleasant procedures, but also pay for a new prosthesis, since in most cases the crown has to be removed. Sometimes the doctor manages to refill the canals without removing the prosthesis. A hole is drilled in the crown, which is closed with a filling after treatment. But this is not always possible.
Not all specialists agree to treat a tooth under a crown. This is very labor-intensive work and there is no 100% guarantee that refilling will save the tooth. Many doctors in such situations immediately refer the patient for removal. Our clinic’s specialists take on even the most difficult cases and use every opportunity to save patients’ teeth.
If inflammation occurs due to underfilling of the canal, but it is impossible to treat with conservative methods, the doctor may suggest that the patient solve the problem surgically - perform resection (cutting off) of the root apex. In this case, the unfilled area, together with the granuloma or cyst formed on it, is removed through an incision in the gum area. The operation is performed under local anesthesia and lasts from 30 to 60 minutes.
The doctor determines the method of treatment in each situation individually, based on the cause and stage of the inflammatory process. Unfortunately, there are situations when it is truly impossible to save a tooth and the only option is extraction and subsequent prosthetics.
Frequent symptoms
The problem under consideration can manifest itself in different ways. However, there is a list of common symptoms that can help determine whether you should see a doctor:
If there is an inflammatory process, the patient experiences pain when pressing on the metal-ceramic crown or when biting in this area. This may mean that the gums under the crown are inflamed. Aching pain in the area of installation - in the presence of pus in the periodontal tissue, pressure increases and pain appears.
Swollen gums indicate a large amount of pus, a serious inflammatory process. Flux is accompanied by an increase in body temperature - it rises from 38 degrees and above. The patient may also feel echoes of pain in the head, temples, eyes, ears, teeth may randomly close and knock against each other.
An unpleasant odor under the crown also appears due to the presence of pus, a fistula (a fistula tract that allows pus to escape) or a cyst.
Features of product repair
Is it possible to repair a dental bridge made of metal ceramics? It is possible, but only if, for example, part of the ceramic coating has chipped - then it is built up with new ceramics or composite. If the metal frame is cracked or falls apart, then even soldering will not help, because... the structure will soon break again at a “weak” point.
“I wore a metal-ceramic bridge without problems for a couple of years. But one day after eating I noticed that a small piece of ceramic had fallen off. I was all worried while I was waiting for an appointment with my dentist. But the doctor repaired this damaged crown very well, it looked perfect. But I was warned not to chew anything hard on this side, because it could break off even harder.”
