Three new crowns are very sensitive. What’s wrong?

IVE HAD SIX PORCELAIN CROWNS ON FRONT. THREE OF THEM HAVE BEEN SENSITIVE NOW FOR 4 WEEKS. MY DENTIST WANTS TO KEEP WAITING BUT IT’S HARD TO EAT NORMALLY. WHY ARE THEY SENSITVE TO FLOSSING BITING DOWN AND COLD WARM TEMPS? IVE HAD A 2ND OPIJNION HE THINKS MY CROWNS MAY BE LEAVING SOME TOOTH EXSPOSED BUT ITS HARD TO TELL THEY LOOK COVERED BUT THERE WAS A SENSITVE SPOT ON ONE AT GUM LINE. THESES 3 ARE ALL ON SAME SIDE.

Vickie,

When new crowns are sensitive like that to hot and cold, it can take a number of weeks for them to fully settle down.

Because of your second opinion, I’m going to assume that there isn’t anything obviously wrong. So the question about why they are sensitive is much less important than the question of what to do about it. Yes, they could be sensitive because part of the tooth is still exposed. Or it could be that they were overly irritated during the crown process. Or some other reason.

But if they are not getting worse, I would recommend just waiting it out. Be gentle with them. Avoid the things that irritate them (except for the flossing – you need to keep them clean). Eventually they should settle down. If they take a turn for the worse, then they may end up needing root canal treatments and you should go back to your dentist to figure out which of the tooth or teeth aren’t healing.
