White resin tooth fillings are common today because they look nice and are kind to natural teeth. But if a filling is supposed to make your tooth feel better after getting a cavity, why is it so sensitive?
Your tooth houses a very secure and sterile environment. The inner chamber is filled with nerves and blood vessels. Wrapped around that are layers of dentin and enamel. Dentin has pores that allow the nerves in your tooth to pick up on temperature changes. Enamel is like insulation that keeps the sensation from being too strong.
When a cavity breaks through the protective enamel layer, it can open up your tooth to major sensitivity.
Fillings, in a way, do something similar. Your dentist has to drill away not just the decayed part of your tooth, but also a little more to help anchor the restoration.
Your tooth will have to adjust to the shock of having a large piece of itself replaced with a foreign material. For some time after you get your filling, your tooth may be unusually sensitive to things like:
Give your tooth a week or so to see if it settles down. In response to the “leak,” your tooth’s dentin will build a thicker and more cushioned layer from the inside.
On occasion, persistent sensitivity can indicate a more serious problem. Your tooth simply may not respond well to the filling. Or, the restoration might have been insufficient, meaning you’d need a root canal or crown. Sensitivity could also indicate that your filling is too high and needs to be polished down a little more.
See your dentist if you feel the sensitivity means something’s wrong.
