I Am Taking 70 Mg Fosomax Tablets And Have Been

I am taking 70 mg Fosomax tablets and have been told that I need numerous tooth extractions. They say it's possible that whether I stop taking the drug or not, I run the risk of bone deterioration in my jaw. The dentist said he didn't think it would matter since I have been on a second round for about a year. Is this a real possibility??? YYYY@YYYY
