I have lost 2 molars on my upper right side of my mouth in the past 3 years… that is how long I have been on Reclast. I have one Reclast infusion/ year. I had no idea there could be a connection! My lower back is very painful, I have osteoporosis and arthritis! Trying to ignore it! I am 72 years old.. have always been very active and taken great care of my teeth.
