Dental Crown Fit
by Pam101799, Jul 21, 2009 07:12PM
I was recently fitted for a crown but was whitening my teeth (over the counter - slow) and didn't make an appointment immediately. When I left the office, they said they would call (approx. 3 weeks) when the perm. crown came in. They didn't call until maybe 5 weeks later. Anyway, I finally went in to have the perm. crown placed only to find out it didn't fit properly. They claim that too much time went by...My question: is approx. 2 months too long to wait?Should my tooth have changed that much in 2 months time? I allowed them to use the cap but there is a black line next to the gum. Also, there is increasing tenderness surrounding the tooth and it's painful to floss. (It feels like the floss goes in and up too far - almost meets the other side if thats possible).
Thanks for your help.

Two months is quite a bit of time for placement of a crown. Its possible that your teeth may have shifted or moved which is preventing the placement of the crown. Usually the crown can be adjusted to fit, if not, it may need to be re-made.
The black line showing may be the metal of the crown showing underneath. The temporary crown usually isn't a perfect fit so it can cause some problems for the gums if its in place too long such as minor gum recession. Its possible that with some gum recession, the margin of the crown where it meets the tooth is showing instead of hiding underneath the gumline.
As for the soreness, I can only guess why. Perhaps the crown is too tight and your flossing harder up there to get it in, there could possibly be a little cement left that's irrigating the gums, the gums have receded (as mentioned earlier) and food may be getting stuck in there more easily and causing an irritation, etc.
When these types of issues arise, its important to discuss it with your dentist as to how best to approach your concerns and get them resolved.
