Dr. Mason told me I had six cavities. I was shocked because I see the dentist every six months and haven't had a cavity in over 20 years. I asked her what would cause such quick decay of my teeth. She didn't know. I decided to get a second opinon from my former dentist ( I switched because he is a long drive.) He is very highly regarded. He said I had NO cavities. None what so ever. A year later I still have no cavities. I have since talked to neighbors that have been seeing her and they have all had major work done by her. Mmmm...
