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.

Fillings are meant to repair damage to your tooth, instead of being a bother you. If your filled tooth is unusually sensitive, you shouldn’t ignore it!
When Was the Filling Placed?
Old fillings can change the shape of your tooth, and new metal or tooth colored fillings take time for your tooth to adjust to. Both can cause sensitivity depending on your tooth’s health.
What Does Sensitivity Mean?
Sensitivity happens when small channels in the tooth structure have opened up a bit, exposing the sensitive nerves to temperature changes. Your enamel layer protects each tooth. Where there is no enamel or there is a break in it, your tooth will become sensitive.
This may mean that:
Just because a filled tooth is sensitive doesn’t guarantee you’ll have to replace the filling, but you should get it looked at, anyway.
If There is a Cavity
If an x-ray or exam reveals that decay has indeed shown its ugly head again, then your only option is to change out the filling. Your dentist will remove it, clean out new decay, and seal the tooth off again in the most conservative manner possible.
Retreating a filled tooth might require that you take things a step further. Depending on the size of the restoration, an indirect filling or crown could be necessary. If the cavity or damage is too deep, you may need a root canal instead.
Contact your dentist for an exam if your filled tooth starts to bother you without any apparent reason. The sooner you take action, the more conservative treatment will be!
