Tooth hurts under seal: the cause of the pain, what to do
Quite often dentists are faced with the problem, when referring to a perfectly restored tooth begins to bother. The patient is also at a loss, especially if since the last visit dentist was not so much time. To understand the cause of this problem beforehand and not blame the doctor, you need to understand the mechanism of occurrence of pain.
What is the reason
What happens to the tooth during the treatment? Enamel and dentin -the main tissue of the tooth. In the structure of dentin dentinal tubules are involved, inside which is a liquid and processes of living cells-odontoblasts that create dentin throughout the life of a person. Odontoplasty themselves are cavity-polyarnoi the camera and get the nutrition and innervation of blood vessels and nerves the pulp. When removing the caries portion of the dentinal tubules open and modify the fluid pressure in the tubules. Information about this through the processes of odontoblasts supplied to the nerve and it is perceived as pain.
It is obvious that the tooth is alive, too, the structure and all interventions carried out regarding it, you can call the operation, as it is the excision and removal of pathologically changed tissues. Aching in nature of pain is considered the norm. Following this intervention, the response of dental substances is understandable-there is a restoration and adaptation to changing conditions. But if the tooth was ill badly is a reason to pay another visit to the dentist. Most often sealed tooth hurts after the following interventions:
- The installation of permanent seal on a living tooth;
- The installation of permanent seal on pulpless tooth (after stopping of root channels);
- Spontaneously a few years after treatment.
Toothache under seal, installed recently on a live tooth
After the treatment discomfort the patient may experience about a month. This is most likely the adaptation aspects related to the development of new dental structures. The description of the symptoms, you can identify the cause of pain in filled tooth.
Pain when biting
Associated either with inflated seal at the bite, or with infringement of technology of installation of the seal. Often patients do not attach special importance, in the hope that the seal is «adapting». But we should not entertain the illusion of permanent filling materials are quite durable and resistant to abrasion. Therefore it is best to consult a doctor and to trim the seal on the bite. The teeth should close like before. If there was a violation of technology of installation of the seal, the pain when biting continues, and will be felt in a specific area of the tooth, and prillerova will not bring results. In this case, it is necessary to completely replace the restoration. Also pain at bite and feeling «grown up» of the tooth is inherent in the teeth with pathological processes at the root tips. The nerve most likely long dead, and asymptomatic chronic pulpitis has led to the spread of infection beyond the root apex. Staging seals and erroneous diagnosis has led to the exacerbation of chronic process in the surrounding tissues. If the treated tooth, there are problems with periodontitis (inflamed gums periodically in a pocket), medical manipulations associated with the installation of the matrices, wedges, etc. can disturb issues associated with periodontitis and cause pain when biting.
Pain from hot and cold
This condition can be caused by several factors. Short-term transient pain may occur after treatment of deep caries, when almost the entire dentin was removed following treatment, and between the cavity of the tooth where the pulp, and between it and the seal left a thin layer of it. Over time, odontoblast will produce a new layer of dentin and this will protect the vessels and nerves of the pulp from the action of temperature irritants. This process takes usually not longer than a month.
If the tooth is not stop moaning, and makes itself felt both day and night, then most likely it is inflamed nerve and chronic or acute pulpitis.
Acute pulpitis occurs as a result of violations of the temperature and speed modes of treatment of carious cavity. Insufficient water cooling can lead to overheating of dental hard tissues and the development of aseptic (without germs) inflammation. Chronic pulpitis occurs without specific symptoms and sometimes the doctor takes him for deep caries. In this case, there is incorrect diagnosis and you need to conduct some additional research (e.g., cold sample, x-ray) to understand why it hurts the tooth is sealed. If the cavity in the tooth or in the roots, the doctor will see changes (the formation of «stones»-denticles in the cavity of a tooth or bone tissue defects on the root tips), you will need to carry out root canal treatment.
Pain when touching the tooth with the tongue
Arise on the background of inflammation on the tops of root canals. Most likely, the nerve died and the pain associated with inflammation in the bone surrounding the tooth. In this case, it is not just a strong ache, and responds to the slightest touch.
After root canal treatment, the tooth filled hurts what to do
The reasons again may be several. Often patients ask the question: how can I hurt a tooth in which the nerves removed? All right, the tooth can not hurt, and therefore there are several reasons
Rarely in the practice of a dentist there are teeth with one straight root canal. To remove all the nerves of the channels rather laborious process, since root canals have many side branches and in order to do a proper endodontic treatment, doctor must clearly comply with all the rules of mechanical and antibacterial treatment and the sealing of the channel. Despite this, the likelihood that one of the microtubules may be the nerve, is very high. Talking about this residual pain from hot and cold that persist after treatment. You need to contact your doctor to re-root perelechivat channels.
Implies the removal of the filling material beyond the root apex. According to generally accepted standards of endodontic treatment, at the radiological control slight removal of the filling paste in the root tip (effect of clouds). Ensure that the channel is sealed really tightly. However, the reaction this material can be very diverse, including pain. Also a small amount of the antiseptic can penetrate behind the root tip during processing of the channel and thereby cause burning of the tissues surrounding it. The pain persisted for about a week and go away on their own. Which really shouldn’t be — because it is a significant (more than 2-3 mm) removing material at the root apex or insufficient sealing. If the x-ray picture shows that the channel is sealed leaking, or not up to the top, this may be a sign not to the end of a remote nerve. Any voids in the canal — this is the place favorable for growth and reproduction of bacteria.
Bleed in remote nerve
Rarely occurring complication in the treatment of pulpitis in one visit. After the doctor removed the nerve, he dries up the root canal. For the final hermetic root filling it is essential to the channel was sterile and dry. However, sometimes the bleeding can start after the sealing of the channel. It is usually insignificant and hematoma usually resolves by itself, and the pain in the sealed tooth disappears without a trace.
Tooth hurts under seal a few years after treatment
The reasons for this vary, but often include the following:
- Exacerbation of chronic pulpitis;
- the development of inflammation on the tops of the roots;
- crack root;
- cleavage of the filling or tooth;
- the violation of the marginal integrity of fillings.
Exacerbation of chronic pulpitis or periodontitis
If in the treatment of infected dentin was removed incompletely, for the development of caries under the filling conditions are favorable. The process quickly spreads deeper into the tooth and affects the nerve and pulp tissue.
This disease may be asymptomatic, going beyond the root. At decrease in immunity, whether it is cold or exacerbation of somatic diseases, chronic inflammation in the tooth or its surrounding tissues will be felt.
The development of inflammation at the tips of roots
Occurs as a result of the poor quality of stopping of root channels, inadequate drug treatment or breach of integrity of the permanent seal. Modern dentistry to ensure absolute sterility of the channels prefer to use a dental dam. This special protection from latex, which is put on the tooth during most dental procedures. The imposition of cofferdam prevents the penetration of bacteria from saliva in the treated and sterile cavity of the tooth. It is then possible to speak about maximum compliance with all the rules of treatment. When the destruction of permanent fillings or crowns to root canals sealed easy saliva and they are infected. It is therefore important to monitor the integrity of the restoration and the loss of fillings or crowns it is advisable to repeat the treatment channels.
If the dentist is recommended to cover the tooth with a crown or inlay, it is necessary to listen to it. The destruction of the hard tissues of the tooth by more than 2/3-direct to this testimony. Extensive fillings are not as durable, and an incorrect load on the remaining tissue can lead to cracks and fractures. If a healthy tooth is covered with large filling hurts when biting-a reason to go to the doctor.
The violation of the marginal integrity of fillings
When using filling materials light-curing the seal «glued» to the tooth with special glue-bond. However, over time there is slight shrinkage of the filling material and the gap of the contact seal bond to the tooth surface. Also, there is «fatigue» the bond and its destruction, then between tooth and filling a gap, which easily penetrate the microorganisms causing tooth decay and pain symptoms.
Tips and advice
Tooth pain to endure is not worth it. Of course, you can take analgesic drug type Advil, Nise or Nimesil. But if you have a toothache under seal and what to do is not clear, it is best to consult a specialist and to conduct a detailed dental examination. You need a thorough examination, x-rays, cold test and electrogoniometry. Regular checkups will allow you to monitor the condition of existing fillings, and compliance with doctor’s recommendations will protect from premature loss of teeth. Timely treatment will save you time and money.
