Anyone had dental problems after taking fosamax (alendronate)?

A qualified Yes: Patients taking Fosamax (alendronate) should continue good oral hygiene practices at home. Nearly all dental treatment can be completed without complication with patients taking fosamax (alendronate). Complications have presented when patients have oral surgery. The complications include extremely poor bone healing; even necrosis. Speak with a surgeon about all risk factors before any invasive treatment.

Slim possibility: Fosamax (alendronate) and other similar medications known as oral bisphosphonates (boniva, actonel) can cause necrosis of the jaw bone if they have been taken for a while. The chances are very low, usually less than 1% but if you recently had any invasive dental work then this could be the cause. You may want to check with a dentist or oral surgeon to verify this. It is easily treatable in it's early stages.

Yes: Osteonecrosis of the jaw is a rare but possible side effect, heaviest with IV fosamax (alendronate)

Osteonecrosis: Unfortunately, Fosamax (alendronate) is associated with osteonecrosis of the jaw bone, particularly if dental surgery or dental extraction is performed in long-term Fosamax (alendronate) users.
