My 2 year old frontal bridge is loose, any suggestions on what I should do?

Unfortunately, if you have one anchor tooth uncemented, you need to get the bridge off. Your dentist is hoping it will loosen on its own. However, in my experience, that is not likely. Without xrays, it is more difficult to advise you. If you wait too long the loose anchor tooth will decay beyond repair and it may be lost. Sometimes, it is better to sacrifice the bridge rather than lose the anchor teeth. I am sorry your bridge only lasted 2 years.

Hi:
Although it is unconventional, sometime if the bridge can be loosened a little bit more so it can be removed easily, it will cause the least damage to the teeth.  However, since you have root canal teeth you have to be very careful.Best,Dr. Maddahi
