What are the risks of fosamax (alendronate) to osteonecrosis of the jaw?

Biphosphonates: From: http://www.merck.com ONJ, which can occur spontaneously, is generally associated with tooth extraction and/or local infection with delayed healing, and has been reported in patients taking bisphosphonates, including FOSAMAX (alendronate). Clinical judgment of the treating physician and/or oral surgeon should guide the management plan of each patient based on individual benefit/risk assessment.

Many: I would consult with your Dr., and maybe even get a second opinion and consider talking to a pharmacist.

Small risk: Small risk of medication related osteonecrosis of the jaw (MRONJ). It MRONJ can occur spontaneously, but most often follows a oral surgical procedure like tooth extraction. Any dental procedure done in a patient on Fosamax (alendronate) or other bisphosphonates should be managed by an oral surgeon.

Uncommon risk: but Fosamax (alendronate) use was conclusively linked to osteonecrosis of the jaw. Ask your OS for more info.
