toothache after the removal of the nerve in dentistry

When a complication of tooth decay takes place, the enamel damage occurs, which leads to the formation of pulpitis. As a result, the person experiences severe pain. Sometimes the only solution to the problem is the removal of the nerve.

Modern treatment methods allow conducting a procedure under anesthesia within a half of an hour. Often, there are situations when a severe toothache occurs after removing the nerve and filling channels, such as biting or pressing on it. Why does it happen, and what to do when it’s time to ring the alarm?

Pain after tooth filling

Depulpation procedure is conducted as follows: after the local anesthetic is being injected, the dentist removes the nerve and performs cleaning of the channels. After the work is done, the seal is being installed.

Under anesthesia, the patient does not experience any discomfort, but in fact, the procedure of removing the nerve cannot be painless. Nerve endings are woven into a single trunk, which is responsible for the sensitivity of the face and jaw.

Therefore, a formation of pulpitis can lead to discomfort in the ear, temple, and forehead. During the process of depulpation, a nerve is being torn off from the common trunk, causing, thus, tissue micro trauma.

Since there is a serious interference in the human body, unpleasant feelings arise in every second patient. These effects are considered to be natural, so they should not cause concern.

In this condition the following symptoms are considered to be normal:

  • Increased sensitivity when exposing to external stimuli (food, cold air, sweet drinks).
  • Discomfort when pressing or biting.
  • Suddenly arising pain, especially at night or during sleep.
  • Discomfort during clamping the jaws.

Over time, these feelings should subside. The worsening of the state of health may indicate inflammatory processes that lead to flux, purulent lesions of the gums.

It is a quite logical question: “How long does a toothache after removal of nerve and filling last?”.

If the tooth hurts more than 7 days, and it becomes more intense and sharp, then there is an urgent need to visit a doctor.

Low-quality treatment

One should be very responsible when choosing a dentist, for unprofessional treatment can lead to serious consequences. In this case, the pain becomes unbearable and lasts quite a long time.

Complications arise for the following reasons:

  • Poor cleaning of channels. This could result in microbes that develop under the seal and cause inflammation.
  • Nerve tissue has been removed not completely. The consequence of this error may be an increase in temperature.
  • The void under a seal. This occurs as a result of incorrect calculations for shrinkage of material. The consequences are quite dangerous and can lead to an abscess, tooth walls decay, the formation of fistulas.
  • The output of material for sealing off the root apex. This error may result in a visit to the surgeon. The doctor will perform a simple operation. It lasts 40 minutes and is aimed at removing the apex of a tooth.
  • Non-standard structure. For example, the doctor observes three teeth roots, but four root canals. In this case, the dentist does not see one of them, so he does not remove it. As a result, the patient experiences discomfort.

For example, re-cleaning of canals runs harder than the first treatment. Therefore, you should remember that professional services cannot be cheap.

If the procedure was carried out poorly, the doctor did not comply with the protocol of removal, or there appeared an unexpected situation during the process of treatment (e.g. tool breakage), the clinic should conduct re-treatment for free.
