When I was numb but still feeling pressure, he stopped and was not going to continue unless I signed Visa authorization-400.00--much trouble healing and he asked if i took fosomax? Went back due to problem healing and when jaw begsn hurting i googled loose teeth and fosomax. This potential pretty awful outcome showed so primary ordered bone scan.. I had to go back again due to bone protrusion.Again, with my abnormal report. He "dished radiologist,my primary and me"-saying I was looking for zebras .But he had brought up Fosomax. He may be good but poor, uncaring manner and while I was there another patient called about failed implant (these fail due to doctor, not implant).After research, I learned an older patient should discontinue Fosomax 3 mths. before surgery(under ADA guidelines).He never questioned this but I had listed it on intake form.In his favor, his staff is lovely and there has been no extra costs for needed followup care, xrays, or visits. And no charge for cancelled appts.
