Filled tooth and it hurts when chewing: causes, prevention

Filled tooth and it hurts when chewing. Found this in the norm and the development of complications in postcombination period. The filling carries a purpose to compensate for the lost tooth, to provide the anatomical integrity of the tooth and functions. However, sometimes after the installation of the material there is pain when biting. Let’s look at the causes of discomfort and remedies.

Features of filling

Treatment of pathologies of the dental tissue is to implement two things: eliminate the cause of disease through dissection and reconstitution of the integrity of the tooth in anatomical and functional terms using restoration or prosthetic. Treatment of caries and not carious lesions involves the following points:

  1. Analgesia, if necessary;
  2. Preparation;
  3. Antiseptic treatment of the cavity with special solutions;
  4. Overlay seals: the installation sequence and the amount of materials used depends on the type of filling material.

Therapy of complicated forms of caries (pulpitis, periodontitis):

  1. Pain relief: with pulpitis always; in periodontitis as needed, in the correlation from the phase of flowing of the process (acute, chronic, exacerbation);
  2. Dissection, opening of the cavity;
  3. Machining of channels, instruments and devices (endodontic handpiece);
  4. Alternating with hand and machine cleaning of the canal system runs medicated irrigation for the purpose of sterilization of the canal from pathogenic organisms;
  5. Filling of the root canal;
  6. The imposition of the seal.

Sealing of the channel is performed temporary and permanent materials. The use of substances for a short period due to influence on a particular symptom, for example, spend antiseptic («Polosatik» in the form gangrenous pulpitis) or osteogenesis influence («Metapex» in destructive forms of periodontitis). After exposure, the material is replaced by a constant. Then install the seal (temporary or permanent). Also temporary filling is placed for a certain period, depending on the clinical situation and the presence of the physician’s time to complete the full restoration.

The reasons contributing to the emergence of the disease

If after sealing a toothache, what factors can cause the discomfort several.

Errors are possible in the following points:

  • Wrong diagnosis and, consequently, the tactics of intervention;
  • Violations in the process of handling;
  • Allergic reaction to components of the applied solutions and materials patient.

Normal after implemented the intervention in the oral cavity by a physician, a patient may feel pain when biting for 2_3 hours. However, if the presence of a discomfort continues for 4_5 and more hours or days, an urgent need to consult a doctor to prevent the development of complications.

Error in diagnosis and outbound from this tactic

The tooth is represented by a structure of hard and soft tissues, United in a single facility located in a special recess in the jaw. On the basis of lesions of these structures and the depth of penetration, produce the disease. Caries and not carious (erosion, hypoplasia, wedge-shaped defect, fluorosis and other) striking rigid structures: enamel and dentin. Consider the example of dental caries.

For carious lesions characterized by the presence of the gradient of penetration:

Caries in the stage spots. In the surface layer of enamel.
Initial. Affects superficial and deep layers of enamel up to the enamel-dentinal border.
Average. The lesions of the enamel and surface layers of dentin, the greatest pain when identification will be celebrated when sounding at the enamel-dentinal connection.
Deep. Lose of enamel and dentin up to the roof of the pulp chamber.

If the doctor, during the examination, for example, establish a diagnosis of «average decay» and will start the preparation and treatment commensurately, despite the fact that actually the patient had a localized process deep. Specialist used special dyes to identify dead tissue («Caries detector») and, accordingly, has not made removal of the infected content to the end.

In this case, even if a properly done restoration, with preserved edge conformity, eventually the chewing will bring discomfort. In addition, if the patient had deep decay, treated as the average, sooner or later the germs penetrate the dentinal tubules system in the tooth pulp and there will determine the development of inflammation in pulpitis, show night, paroxysmal pains, prolonged feelings of cold.

It can also cause erroneous action in the treatment of the tooth about the middle of dental caries, when there is chronic periodontitis. Not to commit wrong actions in relationship therapy, before surgery, it is recommended to do x-rays.

Violation in the process of preparation and restoration

To put the restoration and the tooth will give feedback when I bite you and commit other errors. During preparation the physician may not perform the creation of conditions for fixing material to leave irregularities in the walls, thereby complicating their task execution precision marginal integrity.

Ache sealed tooth when chewing and for violations of the requirements of asepsis and antisepsis. It is extremely important to all interventions in the oral cavity using sterile instruments and conduct antisepticescuu processing. Because the removal of the infection mechanically, not always accurately will help to remove the microbes to the end. For this purpose there are special solutions: 0,05_2% solution of Chlorhexidine digluconate, a 3% solution of hydrogen Peroxide.

Rooting can tooth and after improper restoration. Depending on the used material are different approaches to use. Consider the example of light composites. After you create a cavity under the filling and drying, it is important to apply the treatment gel («Traveks-37») to create microposts in the walls of the tooth, with the aim physical contact of the seal and the tooth. Then after exposure the material is washed, dried and applied the adhesive. This substance is like glue will chemically bind the filling and the tooth. The adhesive is applied, it is important to inflate a small air flow and light to commit. Then the composite is applied in small portions, after modeling the thickness of not more than 2 mm on the walls of the tooth. Each portion is separately lighted by a special light.

If the doctor at some stage made mistakes or have made excess material, the patient gets a complication. If there is excessive overlap of the seal and not the correction of occlusion, over time, the set material will cause the appearance of pain.

Allergy to components of materials and solutions

Had treatment in line with diagnosis and put the seal, but gives the tooth pain when biting. In this case, it is suspected an allergic reaction to components of the seal or solutions. The patient may be unwell: General malaise, fever, edema of the mucosa of the installation area, the presence of lesions on the mucosa or even the skin. In this scenario, the events must be urgently referred to a specialist.

Tactics medical action


If it is more than the allowable time, and the tooth when biting reacts, you ought to consult a doctor. At the appointment the dentist will make a clinical examination, if necessary, arrange for x-rays to monitor changes in the periapical tissues, and produce repeated intervention in the oral cavity.

Ways to prevent

After sealing it is important to load the treated tooth. When powered, the priority is given food soft to medium consistency, preferably a homogeneous substance: yogurt, yogurt, cereal, and other. But it is also important for time to get used to the new material in your mouth to limit chewing on the side of intervention. Allowed the use of analgesics by the physician in a set period. If the event does not give success, and a tooth ache, you ought to go to the doctor on reception, to identify the causes of pain when biting.
