I had caps on the teeth for several years, and they kept coming off, coming off. I did not want to go through the bone graft. It was a little frightening. I thought, "Oh, this might not be so easy the second time," but it was, and it was the third and the fourth time and the fifth time. I had no problem afterwards. This place is amazing and so is Dr. Arnold. If any of my friends anywhere needed an implant, I would highly recommend Dr. Arnold.--Irma
