Dr. Griffin was born and raised in Knoxville, and even as a young child, he knew dentistry would be in his future. Today, his areas of focus at Cornerstone Dental Arts include IV sedation, dental implants, the pinhole surgical technique, and soft-tissue and bone grafting, with a dedication to making implant therapy a pleasant experience for every patient.
Beyond his work at Cornerstone, Dr. Griffin shares his expertise as a faculty member of the Midwest Implant Institute and serves as director of MII Tennessee, teaching other dentists the art and science of implant dentistry.
Dr. Griffin utilizes the Yomi robotic-assisted surgical system — the first and only FDA-cleared robot for dental implant procedures. This technology provides millimeter-level precision for implant placement, resulting in minimally invasive procedures and faster recovery times.
Combined with 3D CT imaging and AI-powered planning, the Yomi system allows for same-day implants in qualifying patients while keeping Dr. Griffin in full control throughout the procedure.
Dr. Griffin gave me a thorough evaluation using high-tech imaging, paired with relaxed, informative explanations. The entire experience was gentle, thorough, and actually quite relaxing. I highly recommend him for quality, conscientious dental care.
Great experience as always. Dr. Griffin doesn't just run in and back out — he takes the time to do a thorough exam, even for a routine cleaning appointment.
After a trauma fall, Dr. Griffin responded immediately even while out of town and got me worked in. He placed temporary teeth and built a plan so I'd have my smile while preparing for further treatment. He and his staff are absolutely the best!
Dr. Griffin did a wonderful job extracting my tooth in preparation for a dental implant. He made sure I was completely numb before proceeding, and all I felt was a little pressure. A very good experience!
Dr. Griffin was professional and friendly, and made care decisions that were logical and least-invasive — saving me a lot of money. Other specialists wanted a pricey procedure I was ultimately able to avoid entirely, thanks to Dr. Griffin.
Dr. Griffin and his staff are fantastic — genuinely concerned for patient comfort while doing top-notch work. I trust no one else, and our whole family goes here.
I've been a patient of Dr. Griffin's for over 20 years, and my whole family trusts Cornerstone too. No other dental practice in East Tennessee comes close — he always puts the patient's interests first and is constantly updating his technology and techniques so we get the best possible care.
