Re: Broken tooth or filling? problems
The filling is more likely to break/fall than the tooth itself, unless you get some hit in this area. If you got an amalgam (black) filling, then its more likely have to be replaced if the chip that broke is large, while if you got a composite (white) filling it might could be repaired, if the broken part is small enough and did not effect the stability of the rest of the filling/tooth.
Anyway, you'll have to see a dentist for consultation.
