Fillings are dental procedures that remove cavities and fill them with selected materials such as gold, silver, composite resin or porcelain.

2.1. Nerve stimulation The enamel layer protects the nerve from exposure, but fillings, especially deep fillings, can get close to the nerve causing itchiness and discomfort in the tooth. Therefore, after filling, the nerve inside the tooth needs a few days to a few weeks to heal. During this time, sensitivity may occur when the stimulus is encountered.
When the nerve heals, the sensation of sensitive teeth will disappear, you will not feel any difference between the filled tooth and other teeth.
2.2. Incorrect bite alignment If the filling is not aligned and too high relative to other teeth, it can increase the pressure when biting, causing pain and sensitivity. Normally, the bite will self-correct during the daily eating process after a few weeks, the sensitive tooth condition will also disappear. However, in some cases, if the pain increases over time or you have difficulty chewing food, you should see a doctor to have your bite checked. On re-examination, the dentist can trim the high point of the filling to fit the bite, eliminating pain and discomfort.
