Dr. Brian F Cahill, DDS
General & Restorative Dentist
Dr. Cahill brings a rare combination of deep clinical expertise and a genuinely down-to-earth chairside manner that puts even the most anxious patients at ease. His thorough approach means he notices the details others might miss — catching a loose implant during a routine cleaning, then making time the very next morning to fix it. Patients consistently describe him as knowledgeable, professional, and one of the most approachable dentists they have ever met.

“
Comfort, expertise, and a smile that finally feels like yours. That's the whole point.
“Such an amazing experience when going to the dentist, and have everyone and Avery Point of Contact be filled with pleasant and professional people. I highly recommend Research Triangle Dental to all - they certainly help maintain my SMILE! Thank You So Very Much!!”
“Everyone at Research Triangle Dental has treated me with common decency & respect, both of which are qualities that I find to be lacking in companies across the board in recent years.
I came to them in an incredible amount of pain, had no insurance at all, and have never in my life have I had a better experience with a dental practice!
My preferred dentist is Dr. Cahill. You can tell immediately that this man holds a wealth of knowledge and experience, as well as a high level of professionalism with the added bonus of a down-to-earth, approachable character. Great guy all around!
I would highly recommend RTD, from start to finish I cannot express enough how comfortable and attentive everyone at RTD has been the few times I have visited.
Thank you to everyone from the front desk staff, to the technicians and doctors, thank you so much for providing a practice upheld to such a quality standard. It is an absolute blessing to have found your practice!”
“Very friendly, knowledgeable, professional staff. I love the hygienist Elena (I think that's her name). She's wonderful! Both dentists are a joy as well. They are also great with financing options for products and procedures. I'd recommend this office to everyone”
“I highly recommend this place 🙌🏼 I had a tooth extraction done, and the experience was much better than I expected. From the moment I arrived, the staff was incredibly kind, attentive, and professional, which made me feel at ease the whole time.
The procedure was quick, well explained, and done with great care. Afterward, they gave me clear instructions for recovery and made sure I was doing well.
I would definitely come back and recommend them with full confidence for any dental treatment. Excellent service!”
“During my dental cleaning on the day before, Dr Cahill noticed that my implant was loose. He told me to come the next morning and that he would tighten it up. I got an appointment at 10:00 today and he was able to tighten it up in about 20 minutes. Thank you!”
