Fosamax and Dental Health
If you, or a loved one has ever taken bisphosphonate drugs either intravenously, or pills, prescribed by your physician to prevent osteoporosis, be aware that you must keep your mouth spectacularly healthy. The reason for this is that it has been shown that these drugs which include:

These drugs can cause osteonecrosis of the jaw (ONJ). ONJ is a very
painful lesion which occurs when teeth are extracted, or jaw surgery is
done in susceptible individuals (bisphosphonate users). The bone is
dead (necrotic) and therefore never heals properly.
The chief of the Division of Oral and Maxillofacial Surgery at LIJ,
Salvatore Ruggiero, DMD, MD, and his staff reported that they were
struck by the appearance of a cluster of cancer patients with necrotic
lesions in the jaw, a condition they previously saw only rarely in one
to two patients a year. When they launched a study of patients' charts,
they found that 63 patients diagnosed with this condition over a
three-year period shared only one common clinical feature: They had all
received long-term bisphosphonate therapy.
Bisphosphonates commonly are used in tablet form to prevent and treat osteoporosis in post-menopausal women. Stronger forms are used widely in the management of advanced cancers that have metastasized to the bone, where the disease often causes bone pain and possibly even fractures.
Several cancers can involve or metastasize to the bone, including
lung, breast, prostate, multiple myeloma and others. In cancer
chemotherapy, the drugs are given intravenously, and usually for long
periods of time.
Proper protocol for individuals would be to have a very thorough dental
and oral examination performed by a highly qualified dentist. Any tooth
which has any possibility of needing extraction, should be removed
before beginning bisphosphonate treatment. Any area in which you are
contemplating having a dental implant placed, should be done at least 6
months prior to beginning therapy with bisphosphonates.
If you have taken bisphosphonates, you should consider never having a
tooth removed again. It can be treated with root canal, and submerged
beneath the gums. There are times when this might not be possible. Be
sure to place your care in the hands of an oral surgical team that has
experience in treating ONJ.
Be sure to tell your dentist if you have ever taken oral or IV
biphosphonates. It is extremely important that you do not keep this
information from your dentist.
