Dentistry - Dark spot on surface of filling
Expert: Lawrence Spindel DDS, www.lspindeldds.com - 11/10/2009
Question
I recently noticed a small dark spot that appears to be on the surface of an old silver filling in the bite surface of a lower molar. I have had no sensitivity, and I develop sensitivity (especially to cold) quite easily when I have any problem in a tooth. Does this sometimes happen with older fillings, or do I need to see a dentist?
Answer
Dear Judith,
Sometimes as silver fillings age they can oxidize and turn black and it does not indicate a problem, but other times fillings can be cracked and the cracked areas appear black. If you haven't been to a dentist within the last 6 months this would be a good time to schedule a check up and a cleaning. When you are there ask your dentist to check out the filling with the black spot. The presence or absence of sensitivity is not always a reliable indicator of trouble.
I hope this information is helpful and please feel free to contact me with any future dental questions.
