she said it interferes with healing. And it causes other problems down the line. I did read about that. But I asked my uber expensive Endodontist and he said there is no ONJ and not to worry. The bisphosphonates can cause issues. But this is why I am staying on the Tymlos. I have had some issues over the years. loving AI for this kind of thing:

Bisphosphonate medications can affect teeth in a few ways:
Osteonecrosis of the jaw (BRONJ): This rare but serious condition can occur when jaw bone dies and becomes exposed through the gums. It can happen after oral surgery, like a tooth extraction, or spontaneously. Symptoms include:
Pain, swelling, or infection in the gums or jaw
Gums that don't heal
Loose teeth
Numbness or a heavy feeling in the jaw
Drainage
Exposed bone
Inhibited tooth movement: Bisphosphonates can inhibit bone resorption, which can affect tooth movement.
Impaired bone healing: Bisphosphonates can also impair bone healing.

So my expensive dentist explained there is a difference between dentin and bone and jaw bone.
The community clinic dentist didn't understand that Tymlos was not a biphosphonate. (they do my cleanings and xrays and saw me on an emergency when I broke my wisdom tooth 3 weeks ago. I did tell you that my trigeminal neuralgia VANISHED after that happened! I must have been walking around with a hairline fracture for a few years. No one caught it! They all agreed it had to have been a gaping fracture for the xrays to read it.
I am lucky to have all three.
