They continued to bill me even though I paid everything owed to them. $50-$100 dlls out of the blue. I must have paid it 2 or 3 times over, until the red flags went up. I said no more. My son received sealer to protect his teeth. It wasn't 6 months later that they wanted to apply sealer again on his teeth and charge me all over again. About a year after getting treatment from them and getting a clean bill of health they started leaving messages on my phone tell me that I needed to have my cavities treated. What cavity?
