Black under filling?!


Question: In a blink, the tooth under my daughter's filling became black. What is that? She's not in any pain.

Her dentist doesn't work Fridays, and the dentist he refers to, well let's just say he's not an option. My daughter is 5 so we need a pedi dentist. Will this easily wait until Monday or will this develop pain?

There are two possibilities for the black appearance under the child's filing you describe. I do wonder about the material used to do the filing since you say you can see under it. At any rate, the two possibilities are as follows. Some filings and crowns are not properly sealed at the edge where they meet the tooth and that provides a pocket where food can lodge. If the food isn't removed it rots and turns black promoting additional decay.. On the other hand in your child's case, what your seeing may be additional decay that wasn't removed when the filing was done in the beggining or an exposed tooth area that is now decaying. Either issue requires you see the Dentist and have the situation dealt with before it poses a more serious issue.

If she is not in any pain I wouldn't worry about it until Monday but I have no idea what could have caused her tooth to turn black. At least it is a baby tooth!

Hi! I've been in dentistry for over 20 years and several things can cause this. If the area under the filling was not completely sterile and bacteria was present, it could be re-occuring decay. If she is not in pain, this can wait until Monday, just make sure she brushes and rinses thoroughly and use a fluoride mouth rinse before bed. It is also possible the nerve is dying and the tooth may need to be removed. But I wouldn't panic and wait until the dentist can see her and determine if this is something easily re-done and take it from there. Good luck. ~M

Recurrent decay, marginal breakdown, or stains.

She should see her dentist.
