Does anyone know the best way to get proper diagnostics care for a possible tooth fracture without being given the run around and ripped off by dentists? Whilst extracting my last wisdom tooth (in the US) the dentist must have made a bad mistake, because right after the procedure I couldn't bite down properly on the affected side on my mouth. I went for years with this situation, and started experiencing occasional pain on that side. Whilst a teaching assistant the the University of Washington (UW), I used to visit UW Medicine for faculty, telling the dentists that I suspected a fracture (based on my research). However they would invariably just throw me off, claiming it was very hard to identify such cracks, it might not actually be a crack, etc. Eventually I lost that tooth, almost certainly due to the widening crack, as I suspected. Now back home in Ghana, another tooth seems weak when eating certain very hard foods, and again I suspect a crack. Again, dentists in general seem unwilling to really address it, halfheartedly trying various diagnostic procedures that do not actually uncover the problem. One was quick to propose a root canal, which seemed weird to me as the first line option to address something like that. This dentist describes himself as a root-canal specialist, and it's not a stretch to assume that he sees every dental problem in terms of root canals. Another dentist suggested it was a small cavity, and did her drill and fill routine, which has done nothing at all to alleviate the problem. Yest another dentist claims I need some tooth tissue filed away to correct the problem. So now I'm not sure what to do. It seems cracks are hard to identify; I'm not sure why dental imaging cannot help much here. I'd like to know if there are better options than dealing with lazy dentists who just want your money.
