Q & A
Concerning Bisphophonates and Osteonecrosis
Published by the ADA
What is osteonecrosis of the jaw?
Bone is a living tissue with living cells and a blood supply. Osteonecrosis means death of bone which can occur from the loss of the blood supply or by a problem with the bone’s ability to regrow. Very rarely, osteonecrosis of the jawbone has occurred in individuals taking oral bisphosphonates for treatment of osteoporosis or Paget’s disease of bone. Dental treatments that involve the bone can make the condition worse.
What is the risk for developing osteonecrosis of the jaw?
Your risk for developing osteonecrosis of the jaw, from using oral bisphosphonates, is very small (estimated at less than one person per 100,000 person-years of exposure to the drugs Fosamax, Actonel or Boniva); but, if it does occur, it may be a serious condition with no known treatment so you should be aware of this complication. At this time, there is no way to determine who will develop the disease. However, the condition is rare and has just recently been associated with the use of oral bisphosphonates. It is important for you to understand that other factors may play a role in the development of osteonecrosis, such as other medications you are taking and health problems that you may have.
Should I stop taking the oral bisphosphonate?
The benefits of reducing hip fractures and other complications associated with osteoporosis, can be very important. Your dentist cannot advise you about these benefits. You should talk with your physician if you have any questions. Also, it has not been shown that stopping use of the drug will decrease your risk for developing osteonecrosis.
What are the risks associated with dental procedures?
Although the risk is low with any procedure, it is higher with procedures involving the bone and associated tissues, such as tooth extractions. Your dentist will be able to tell you if the procedure will involve these tissues.
How can I decrease my risk of developing osteonecrosis of the jaw?
Talk to your dentist about oral hygiene, because maintaining good oral hygiene is the best way to prevent oral diseases that may require dental surgery.
What are the signs and symptoms of osteonecrosis of the jaw?
You should tell your dentist immediately if you have any of the following
symptoms, now or in the months following treatment:
- feeling of numbness, heaviness or other sensations in your jaw
- pain in your jaw
- swelling of your jaw
- loose teeth
- exposed bone
What other choices do I have if I do not have the procedure?
Your treatment options depend on the oral health condition that you have. Your dentist will be able to discuss treatment options with you.
Risks associated with not having the procedure?
Your risk for developing osteonecrosis of the jaw is very small. You may be at increased risk for developing other health problems if a dental disease is not treated. Your dentist will be able to discuss alternative treatments, other risks associated with various treatment options, and the risk of no treatment, even temporarily. You should also consult with your treating physician about any health risks.
