Toothache after treatment is not unusual. The most common cause of toothache after filling is postoperative hypersensitivity. What else causes toothache after drilling and filling? How long does such pain last? Is there anything to be afraid of?

Toothache after treatment(after filling a carious cavity, filling) is most often caused by hypersensitivity. There is no unanimous theory of hypersensitivity development after tooth filling. There are various possible causes - the effect of pulp microtrauma caused by the carious process, as well as mechanical, chemical or thermal trauma occurring during the preparation and filling of the cavity by a doctor.

Toothache after treatment - causes

Another theory takes into account the role of marginal micro-leakage in the development of hypersensitivity. The structure of the tooth shows that all pathological processes in the tooth's tissues, even those involving only the surface layers of the dentin, indirectly affect the condition of the pulp and may cause its inflammation. During caries treatment, the doctor must thoroughly clean the cavity from cariously changed tissues. For this, he uses rapidly rotating drills of various shapes. The dentist's actions cause additional irritation of the pulp, as well as the opening of the dentinal tubules. Such open dentinal tubules become the way of conduction of stimuli from the external environment towards the pulp irritated by pathological stimuli. Hypersensitivity pain most often occurs in response to eating warm or cold foods. It can also be provoked by sweets or the flow of air (e.g. when breathing through the mouth). The discomfort disappears as soon as the stimulus stops working. Unpleasant sensations related to hypersensitivity usually appear on the same day of the procedure. Symptoms usually disappear on their own after a few days, but in some cases they may last as long as 1-2 weeks. If the pain persists or gets worse, we should see a dentist as soon as possible.

Another reasontoothache after fillingmay be an incorrectly shaped filling surface. Under normal circumstances, the forces involved in chewing or clenching the teeth are evenly distributed over all teeth. If one of the teeth "sticks out" above the other, then almost all the strength is focused on it,which causes its overload. The pain associated with "too high" filling occurs on the same day that the filling was placed. It is provoked by pressure or biting on the treated tooth. In this case, it is necessary to visit the dentist and correct the shape of the filling.

Another cause oftoothache after fillingmay be gum damage. It results from the dentist's actions in the gingival area. Often, for the correct placement of the filling, a retraction thread or matrix strip must be folded into the gingival groove. This can irritate the gums in this area. The pain associated with such an injury may mimic toothache. It usually clears up on its own after a few days.

In some cases, the carious lesion is very deep, reaching the area of ​​the pulp. This can cause irreversible pulpitis or necrosis. In the course of this pathology, there is an unpleasant pain of considerable intensity. It appears spontaneously or in response to thermal stimuli. Often, unpleasant symptoms appear at night and are so bothersome that they wake you up from sleep. In many cases, pain occurs when biting. The appearance of these symptoms should prompt you to visit the dentist's office as soon as possible.

Toothache one month after the filling

The cases presented above describe the conditions in which pain occurs immediately after the filling is performed. However, in some cases, discomfort with filled teeth may appear months or even years after the tooth has been treated. It may be associated with many irregularities, including

  • secondary caries
  • irreversible pulpitis and gangrene
  • wear or cracking of the filling
  • loss of marginal integrity

How to relieve a toothache?

Pain treatment of a filled tooth

If disturbing symptoms appear, go to the dentist's office. It is best to go to the dentist who put the filling. He knows best the condition of the tooth, how deep the carious lesion was, etc. This makes it easier to make a proper diagnosis and implement appropriate treatment.

If hypersensitivity is the cause of toothache after treatment, intervention is not recommended. The tooth should be observed. During this time, you should avoid irritating stimuli and properly care for oral hygiene. It is recommended to use toothpaste for tooth hypersensitivity. If there is no improvement, the pain worsens, or symptoms of irreversible pulpitis begin to appear, root canal treatment may be required.

In the case of toothache related to "too high"filling, the shape of the filling will be corrected in the dentist's office.

If the tooth's vitality has not been preserved or the pulp has irreversibly inflamed, endodontic treatment or tooth extraction is necessary. Endodontic (root canal) treatment consists in the thorough removal of the inflamed or dead pulp and filling the root canal system with the appropriate materials.

In case of pain related to wear, cracking or loss of tightness of the filling, it is necessary to replace it. A similar principle applies to the diagnosis of secondary caries.

Tooth structure

The tooth consists of three types of tissue. From the inside, the pulp, the surrounding dentin and the most superficially located enamel are distinguished. The pulp, which is located in the tooth chamber and root canals, is surrounded by hard tissues (enamel and dentin). It is the only tooth that is listed among the components listed above and is a living tissue. The pulp is richly supplied with blood and innervated, with numerous blood and lymph vessels and nerve fibers running through it. Pulp consists of many types of cells, including the characteristic odontoblasts, cells responsible for the production of dentin. Dentin is a hard tissue closely related to the pulp of the tooth. The microscopic structure of dentin shows numerous small tubules running from the pulp towards the enamel. dentinal tubules. In a living tooth in such a tubule there is a nerve fiber, an odontoblast appendage and a tubular fluid. Such a complex complex of pulp and dentin is called the endodontium in the professional literature.
