Hurts a tooth after filling


Dentist patients, as a rule, are very surprised if a tooth ache after filling. There are two main behaviors: disregard discomfort, expecting it to disappear over time, or return immediately to the dental office. Let's find out which actions and in which case will be correct.

Can a tooth ache after filling? First of all, I must say that there is nothing strange in this situation. There are many factors that cause pain after the completion of dental treatment. Safe, not requiring medical intervention can be considered weak pain, which becomes slightly stronger with the load on the tooth. These sensations must pass within 10-14 days, maximum - 2 months. Other types of discomfort, most likely, indicate the occurrence of a serious dental problem.

10 risks trapping after treatment

Can a tooth ache after filling

To find out why the tooth hurts after filling the canals, you need to analyze the actions of the doctor. Before filling the root canals with appropriate material, the doctor removes diseased tooth tissues, and if necessary, heals the canal and periodontal - the ligament that holds the tooth in the hole. As a result of these manipulations, the tissues can be slightly damaged, and the patient will begin to complain that after filling, a tooth aches a little, especially when pressed. This is not a pain.

The discomfort will be stronger and more dangerous to health if the dentist made a mistake, showed inattention or simply "something went wrong."

Surface treatment of the tooth and fillings enhanced light flux

If the carious cavity is closed, but the pulp is not removed, excessive light can lead to pulpitis.

Untreated pulpitis

Wanting to keep the tooth alive, the doctor before filling can try to cope with infection and inflammation of the tissues without removing the nerve. But sometimes the pulp cannot be cured. The spread of inflammation to the top of the tooth exacerbates the problem. If you close such a tooth, the person will begin intolerable jerking pains.

Incorrect opening of the tooth cavity

Rough clipping of tooth areas affected by caries often leads to trauma to the pulp. In addition, if the acid gets to the hard tissues of the tooth during the doctor's work, then burns and inflammation accompanied by severe pain cannot be avoided.

The gap between the crown and filling

Sometimes, the doctor sets the crown, incorrectly calculating the shrinkage of the seal. The resulting opening becomes a breeding ground for bacteria that destroy the tooth.

Poor cleaning or insufficient filling of root canals.

The tooth is very sore, even after nerve removal and filling, if the dentist has not properly cleaned the canals, and there are particles of tissue that gradually begin to rot and provoke the development of a strong inflammatory process. Insufficient filling of the root canals with a filling material is also fraught with pain.

Allergy to filling material

Allergy to filling material

When starting a dental treatment, the dentist should test whether the proposed filling material is appropriate for the patient. Neglect of this precaution is fraught with sad consequences. The patient not only has a toothache after filling, but also allergy symptoms appear: skin itch, rash, swelling. The seal will have to be replaced as a matter of urgency.


If the inflammation caused by one of the listed reasons extends to the periodontium, chills and an increase in body temperature up to 40 ° C may begin. Of course, the patient with such complaints need emergency medical care.


The formation of a small abscess on the root of a tooth may not manifest itself for a long time. But if untreated, a person will experience pain, swelling of the gums, hyperthermia, weakness.

Secondary caries

After a certain time (on average 5-6 years), the filling ceases to be a guaranteed protection against microorganisms destroying dental tissues. In addition, the carious cavity may increase under the filling, if it is deformed or its edges are initially loose on the tooth.

Healing edge of the seal

It happens that the filling changes the original shape of the tooth, and when the jaws are closed, the soft tissues are injured, and the load on the tooth increases, which as a result of what is happening after the filling is pained when biting. Until it came to changes in the temporomandibular joint, it would be right to consult a doctor for grinding the bite fillings.

Pain requires not patience, but knowledge

Making sure that after filling the canals there is a slight toothache when pressed, you should not arm yourself with patience and wait until the painful 2-3 weeks finally end. You can take simple, proven by national experience measures:

after filling the canals there is a slight toothache

  • rinse your mouth with saline or decoction of sage, chamomile, yarrow, oak bark, St. John's wort;
  • put on the suffering tooth cotton wool soaked with tincture of propolis, lemon balm or valerian;
  • for 10 minutes, make a compress with 6 drops of fir oil (make sure that the oil does not get on the gums, otherwise there may be a burn);
  • attach a piece of ice to the sore spot;
  • wipe the painful area with a cotton pad dipped in clove oil.

An alternative to traditional methods are pain medications:

  • Nimesil;
  • Tempalgin;
  • Ketorol;
  • Nise;
  • Ketans, etc.

When should the treatment be resumed?

It is necessary to decide what to do when a tooth hurts after filling, given the nature of the pain syndrome and the well-being of the person. Put aside herbal and pharmacy medicines and hurry to the dentist if:

  • "progressive" relief is not observed;
  • very strong pains, such as jerking;
  • swollen cheek from the side of a sealed tooth;
  • there are signs of an allergic reaction;
  • increased body temperature;
  • general state of health worsened - fever, weakness, headache appeared;
  • pain does not disappear for more than 2 months.

Should a tooth ache after filling? Such a phenomenon is optional, but may well take place. Do not worry about the slight pain that is weakening every day. Moreover, it is easy to ease the period after dental treatment with the help of traditional and traditional medicine. But in case of indisposition, swelling, severe pain and other alarming “bells”, it is better to return to the dentist’s office as quickly as possible so that the small tooth does not cause a long, serious and dangerous illness.
