I'm not too fussed about dentist visits. Only ever had two fillings and my wisdom teeth removed.
My last employer, however, suffered with her teeth. I think they were made of glass as she was constantly chipping them, which would then lead to infestation or rot; or her old crowns would fall out.
In the two years that I worked for her, she probably had about 8 (or more - I stopped caring after a while, and to be honest near the end of my employment I got a little sadistic thrill every time she complained she was in pain) visits. Needless to say she loathed dentists.
