Wondering if my 3-month old replacement filling should suddenly start being sensitivity to hot/cold??


Question: I had a silver filling replaced on my bottom tooth, before last one on the right (excluding wisdom teeth, since those have been removed). It was replaced in August, and just recently became sensitive to hot/cold. It was replaced with a white filling (although I could have sworn that they worked on that area twice, and the first time I saw a silver filling being placed... Could they have overlapped fillings for extra protection ?). It's been about a week so far, I'm wondering if it's the sensitivity is a natural thing, or did I somehow dislodge the filling while it was settling?

I was also fitted with a night guard at the end of October, to reduce night time grinding, so from August to October, I could have been grinding my teeth at night.

Thanks!
Answers: white (or composite) fillings can be sensitive for a couple of months after the filling has been placed. the filling material shrinks slightly (silver expands) and can cause some discomfort.

also, the tooth has to recover from the filling being placed by building up secondary dentin (insulation for teeth) and this takes time.

typically silver and white are not layered together for protection.

grinding can also increase sensitivity. i would wait a couple of weeks and see if things change and if they do not you might want to check back with your dentist.
