I Have Degenaritave Disk Deasease. I Have Been On Levertraceatram

I have degenaritave disk deasease. I have been on levertraceatram keppra generic. For 6 years. My teeth are rotting from the inside.. I have lost alot of weight from not being able to eat. My bones rub against one another because the protection layer is gone. Is it possible that the keppra did this. I am 34 and was in goof health before the med change5 years ago. Can the med explain this
