I have a six tooth bridge that makes up all of my front six teeth. The bridge was installed by a dentist in another city less than two years ago. Since that time I have moved and begun seeing a new dentist. She was looking at my recent x-rays and remarked that my bridge would fail soon because there are two spots where it is not flush with the teeth it is anchored to. She showed me the x-rays and pointed out what look like very tiny gaps between the top of the bridge that overlays the tooth and the remaining top part of the tooth that appears to be just outside of the gums. The x-ray had to be magnified to see these gaps.
I have not had any problems with the bridge and have kept it very clean. She gave me copies of my x-rays to take to my old dentist. She also mentioned that if I had got the bridge done at her office, the redo would be free. I'm not sure if she is giving me sound advice or just looking to make some extra money by scaring me into allowing her to redo the bridge. Should this be a legitimate concern?
