What is tooth sensitivity?

The feeling of having sensitivity in teeth is when mild discomfort in the teeth when they come into contact with hot or cold beverages. This is a normal side-effect a person can get after specific dental procedures such as tooth fillings, tooth extractions and the installation of dental implants. The reason for the sensitivity is usually because the nerves inside the tooth may be inflamed after the procedure.

Causes of tooth sensitivity weeks or months after getting a filling

Tooth sensitivity right after a dental procedure is normal. However, if the sensitivity persists weeks or months after the process, it may be a sign of a more profound and more severe issue that needs to be addressed.

Interfering with the bite

If the filling is not correctly fitted, or if it causes disruption with the bite of a person, the filling may be damaged when the person bites down on food. This may cause cracks on the filling. If a poorly fitted filling is left untreated, it may break or fall off, leaving the tooth unprotected. If a filling is not installed correctly or positioned, the person should see a dentist reshape the filling.


There is a chance that an infection has developed inside the tooth, causing the discomfort that the patient feels.

Cracks and damage to the teeth or filling

If there is damage to the teeth or the filling, the nerves and sensitive tissues inside the tooth may be exposed, triggering tooth sensitivity if exposed to beverages that are too hot or cold.

If a patient feels tooth sensitivity months after a filling has been placed on a tooth, one can assume that there is an underlying cause. The standard timeframe for tooth sensitivity after a filling should only be for a few days to a few weeks after the filling was put. It is a sign that there is something wrong if the tooth sensitivity persists after this timeframe. 

The right thing to do is to visit your dentist. The dentist will be able to find the problem with the tooth or the filling and correct it to get rid of the sensitivity of the tooth. If it has been months since your tooth filling procedure, and you are experiencing pain or sensitivity in your tooth, consult your dentist and get treatment for your tooth sensitivity.
