Never heard of this nor experienced any loosening of teeth with OP! In fact, the opposite should be true. Whatever is going on there, it is not due to OP. You might check out the topical calcium therapy at calcium therapy.com. It is specific for gum disease and one of the effects is tightening of teeth. Vitamin C and D3 are also very important for teeth, jawbone and connective tissue. At least 5,000 mg of C and 5,000 IU of D3 per day. Good luck!
