Tooth sensitivity after filling

tooth sensitivity after filling

The process of filling is where the dentist repairs a decaying tooth by filling the small hole with new materials such as gold, silver, a composite, porcelain, or amalgam. The procedure is simple and painless due to the use of numbing agents which wear off in hours. During this time, before the numbing ends, people are urged not to take any food or drinks to avoid biting their cheek or even the tongue. After the procedure, people take time before they can adjust to the changes which cause sensitivity. Visit to learn more.

The factors that may trigger tooth sensitivity include:

  • tooth sensitivity after fillingSugary substances such as chocolate or candy
  • Hot drinks such as coffee or tea
  • Acidic drinks such as juice
  • Cold drinks or foods such as ice cream or a cold soda
  • Biting down when eating
  • Cold air hitting the tooth when breathing through the mouth

These factors are just triggers, but there is a reason why the tooth is sensitive to these factors.

The causes of the sensitivity include:

Incorrect tooth alignment

This is when the repaired tooth is maybe taller from the others in the mouth hence causing pain when biting down or when trying to close one’s mouth. This event may take a few days to adjust to but if the pain is severe, then it is important to go back to the dentist.

Inflammation of a nerve

During the procedure, the dentist may aggravate the nerve or cause inflammation during the drilling process. This event majorly falls on the decays which are deep. During the procedure, the dentist may get close to the nerve endings which cause irritation. With time, the nerve heals, and the sensitivity goes away.


This is the inflammation of the pulp deep in the tooth. It does not occur in minor fillings, but when it happens, it may be caused by trauma if the tooth broke due to an accident, the tooth has been filled several times or the cavity was too deep.
