Dr. Rivera, his wife and three daughters are pleased to make Peachtree City their home. Prior to moving to Peachtree City in 2000, Dr. Rivera was a faculty member at the Medical College of Georgia School of Dentistry for eleven years. While at MCG, he was very active in the faculty practice, concentrating his interest in the treatment of complex prosthodontics patients and patients with temporomandibular disorders as a member of the faculty practice orofacial pain team. During that time, he was also a director of the Prosthodontic Residency TMD clinic. Dr. Rivera was Board Certified in prosthodontics. The American Dental Association recognized Orofacial Pain as a dental specialty in 2020. Dr. Rivera is a specialist in Prosthodontics and also Orofacial Pain. He is fluent in English and Spanish. Since 2021, Dr. Rivera has limited his practice to the treatment of Orofacial Pain, including temporomandibular disorders, and headache, and the fabrication of oral appliances to treat obstructive sleep apnea.

In September 2023, Dr. Rivera earned the “AQH” (Added Qualification in Headache Medicine) by passing a competency exam administered by the National Headache Foundation.

The AQH was originally created in 2000 to recognize physicians with an advanced level of experience in headache medicine. In 2005, board certification in headache medicine was established by the United Council for Neurologic Subspecialties (UCNS), and the AQH program became dormant

In 2012, the Board of the NHF recognized the growing number of allied health care practitioners along with primary care physicians, who had gained experience in the diagnosis and treatment of headache. They also determined, as a service to those experiencing headache, that the NHF-endorsed AQH should be reinstated. The goals are to establish the standards for headache practice and assist those with headaches in locating clinicians who could provide optimal headache-related health care.

What People Are Saying

I came in on 3/25/2019 to have a deep cleaning done. This wasn't an easy task as I still have braces on and have no date in the near future for their removal. Nonetheless, from the moment I walked in, the staff member at the front desk was very welcoming. The doctor who came to numb me was very kind and comforting. The young lady who did my x-rays was also, and the hygentist was simply amazing. He was very friendly and caring. He took time to explain everything he was doing and checked in often to ask how I was doing. He was also very personable. So, I'd like to thank you all for such a pleasant and wonderful dental experience!!!

The dentists & all the staff are very caring, knowledgeable & efficient. I’ve had a lot of dental work done over the years & this practice is top notch!! I’ve not had any pain with any of their procedures, in fact, I actually fell asleep during a root canal (no calming medications involved) & woke myself up snoring!! True story! I am grateful for their excellent care & highly recommend them!!
