I was terrified- I had a bad experience with another Periodontist and was referred to Dr. Mazer by Dr. Jeffrey, also at Dental One. Dr. Mazer was so patient, and answered all of my questions. ( I was really scared, so my husband was terrified!) Dr. Mazer even gave me his phone number in case I had a problem over the weekend. I have not had any problems with the implants, and I'm so glad I had them done. They weren't cheap, but it was well worth it! I would highly recommend Dr. Mazer (and Dr. Jeffrey!)
