Here's my two cents too. You are way too young to be taking any of these drugs to avoid osteoporosis but I want to let women know that one of the side effects of these drugs is necrosis of the jawbone. Necrosis means death of the jawbone! It is found in the fine print (very tiny) in the literature that accompanies these drugs. My dear friend who is 82 years old and still has all her own teeth, found that after taking one of these drugs two of her back teeth were loose. When she went to the dentist, he asked her what medications was she taking? She then checked in with the doctor who prescribed this drug who said to her that's one of the side effects for a small percentage of women. AND here comes the best part! This doctor blamed her for not asking about side effects. Tell me about this so-called best medical care in the world!
