These drugs increase bone density by slowing the body’s natural turnover of bone cells.

Bisphosphonate drugs linked to osteonecrosis of the jaw
Bisphosphonate drugs have been associated with a serious condition causing jaw bone death, also referred to as osteonecrosis of the jaw (ONJ). This medical condition results in chronic pain and disfigurement and is very difficult to treat. Symptoms of jaw osteonecrosis include jaw pain, toothache, exposed bone, pain and swelling in the jaw, soft tissue infection, altered sensation, numbness, and loosening of the teeth. The jaw is particularly susceptible to this condition since it absorbs ten times more of the bisphosphonate than other bones in the body. Bisphosphonates accumulate in the bones and may remain in the bony tissues for perhaps up to twelve years after discontinuation. Patients undergoing dental procedures and those who are simultaneously using corticosteroids are at particular risk for developing jaw osteonecrosis. Also, patients should inform their dentist about using bisphosphonate drugs prior to any tooth extractions, dental implants, etc.
Fosamax Linked to Unusual Fractures of the Thigh Bone
Many patients who have taken Fosamax and/or other drugs in its class have suffered serious, atypical thigh bone (femur) fractures after long-term use. In 2010, the FDA issued a warning to patients and the medical community about a possible increased risk of femur fractures in persons taking Fosamax and other drugs used to treat osteoporosis.
