Hi I'm on Letrozole I get all the side effects, aching bones and pain. However in answer to your dentistry problem. I have always had my check ups and within months of taking Letrozole I needed 3 fillings. 6 months later I go for check up and need another 2 fillings (dentist asked me what I was doing to need so many fillings) .Sadly I refused to have any more fillings so the teeth still need filling. My doc asked how I was coping and I burst out crying saying that with all the problems I've been through, and now my teeth are falling apart. He said it is from the tablets. I now have toothpaste called duraphat (I get it on prescription.) Not sure if that helps, but you're not alone
