Can Fosamax cause problems with teeth?

Answered by Randy McIntyre

It is possible for Fosamax to cause problems with teeth. While the occurrence of teeth-related side effects is rare, there have been reports of individuals experiencing jaw osteonecrosis as a result of taking this medication.

Jaw osteonecrosis, also known as ONJ, is a condition where the bone tissue in the jaw does not receive an adequate blood supply and eventually dies. This can lead to the death of the jawbone and potentially result in the loss of teeth.

It is important to note that the risk of developing jaw osteonecrosis from Fosamax is relatively low. Studies have estimated the incidence to be less than 1% in patients taking the drug for osteoporosis. However, the risk may be higher in individuals who are receiving higher doses of Fosamax or who have received treatment with the medication for an extended period of time.

The exact mechanism by which Fosamax can cause jaw osteonecrosis is not fully understood. It is believed that the medication may interfere with the normal bone remodeling process, leading to an accumulation of dead bone tissue in the jaw.

Symptoms of jaw osteonecrosis may include pain, swelling, infection, and loosening of teeth. In some cases, exposed bone may be visible in the mouth. If you experience any of these symptoms while taking Fosamax, it is important to seek medical attention promptly.

If jaw osteonecrosis is diagnosed, treatment options may include antibiotics to treat any infection, pain management, and in some cases, surgical removal of the affected bone. It is important to note that the management of jaw osteonecrosis can be complex and may require the involvement of various healthcare professionals, such as dentists, oral surgeons, and rheumatologists.

To minimize the risk of developing jaw osteonecrosis while taking Fosamax, it is recommended to maintain good oral hygiene practices, such as regular brushing and flossing, and to schedule regular dental check-ups. It is also important to inform your healthcare provider and dentist if you are taking Fosamax or any other bisphosphonate medication.

While rare, it is possible for Fosamax to cause problems with teeth, specifically jaw osteonecrosis. It is important to be aware of the signs and symptoms of this condition and to seek medical attention if any concerns arise.
