Possibly..: Rarely in some patients who take bisphosphonates such as Fosamax, (alendronate) osteonecrosis of the jaw can occur. This may necessitate stopping the medication and seeking evaluation by a dentist/oral surgeon. You should share your symptoms with the physician who prescribed the medication.

Fosamax (alendronate): This medication works by preventing the bone from remodeling, and that's why it helps with osteoporosis. I am unaware of any effect on actual tooth structure, and your post does not state where you are getting your infections. I suggest that you have a thorough dental exam to determine the condition of your teeth.

Impertinent: I have never found any mention of dental problems connected to Fosamax (alendronate) in any of the literature I have read. Dental extractions are the exception.
