About Oak Hills Periodontics

If your dentist has referred you into San Antonio's Medical Center district, 5419 Fredericksburg Road is an easy address to find. Oak Hills Periodontics sits on the district's main spine, between the hospital campuses to the northwest and the Wonderland of the Americas corner to the southeast. For patients living around Oak Hills, Balcones Heights, Castle Hills or the older neighborhoods inside Loop 410, that is a short drive; for anyone already coming to the Medical Center for other appointments, it stacks neatly onto the same trip. Clinical days begin at 7:30 a.m. on Monday, Tuesday and Thursday, with a Friday morning session that ends at noon.

This is a specialist office. Dr. Pamela Ray and Dr. Gabriella Diaz practice periodontics, which means gums, the bone underneath them and the implants that go into it, rather than routine fillings and family checkups. Gum recession is a large part of the work, and the repair is more interesting than it sounds. When the gum margin has crept down a root, a connective tissue graft borrows a thin layer of tissue from the palate, or uses a processed donor graft, and tucks it under the gum at the recession site, where it takes on a new blood supply and rebuilds thickness. Done in time, it covers exposed root, calms the cold sensitivity and stops the recession progressing. Done late, the bone already lost underneath limits how much root can be covered, which is why coverage should be quoted as a realistic percentage rather than a promise.

The same surgical skill set covers implant placement and bone grafting, crown lengthening for teeth broken near the gum line, treatment of gummy smiles where too much tissue shows on a smile, full-mouth reconstruction planning and dentures. Deep cleaning and periodontal maintenance keep treated gums stable afterwards.

Because this is a referral practice, most patients arrive from their own dentist and keep going back there for cleanings and crowns. That split is a feature rather than an inconvenience: the surgical phase happens here, the restorative phase happens where your records already live, and the two offices coordinate the sequence. Bring the referral notes and any recent radiographs to the first visit and you will save yourself a step.

Oak Hills Periodontics sits at 5419 Fredericksburg Road in San Antonio's Medical Center district, convenient for Oak Hills, Balcones Heights, Castle Hills and the neighborhoods inside Loop 410. Dr. Pamela Ray and Dr. Gabriella Diaz limit their work to periodontics: gum recession and soft tissue grafting, gummy smile correction, crown lengthening, bone grafting, implant placement, full-mouth reconstruction and dentures. Clinical days begin at 7:30 a.m. Most patients arrive on referral and keep their own dentist for routine care.

Frequently Asked Questions

Do I keep my regular dentist if I am treated here?
Almost always, yes. This is a surgical specialty practice, so the periodontal work such as grafting, implant placement and crown lengthening happens here, while cleanings, fillings and most crowns stay with your general dentist. The two offices exchange notes and imaging so the sequencing lines up. If you were referred, bring the referral letter and any recent x-rays to the first appointment, which avoids repeating radiographs unnecessarily.
Will a gum graft fully cover an exposed root?
Sometimes, but not always, and the honest answer depends on the bone between your teeth. Where that bone is intact, root coverage is often close to complete. Where recession has already taken the bone with it, a graft can thicken the tissue, reduce sensitivity and halt further loss without covering every millimeter of root. A periodontist can estimate the likely result after measuring the defect rather than guessing from a photograph.
What days can appointments actually be booked?
Clinical sessions run from 7:30 a.m. to 4:00 p.m. on Monday, Tuesday and Thursday, plus a Friday morning that finishes at midday. Wednesdays are given over to administrative work rather than treatment. That early start suits patients who would rather have a procedure done before the workday than after it. If you need late afternoons at the end of the week, plan around the Friday cutoff and the Wednesday closure.

I had a gum flap procedure and tooth extraction done. Dr. Diaz and her staff were so wonderful, kind, and I felt at ease which is a big deal for me since I have a lot of anxiety around dental care. The experience was 100 times better than anticipated! Very professional and compassionate.

I had a great experience here. This place was a top choice recommended by ChatGPT and my dentist. I had to wait a little bit for an appointment, but it was so worth it. Dr. Diaz shook my hand, was friendly and took her time thoroughly explaining everything to me. Instead of selling me on a procedure, she helped me understand why I wasn’t a good candidate for It and she was correct. I really appreciate the honesty and can tell that these dentist are very knowledgeable. I will definitely refer my friends here!

The level of professionalism and knowledge base that Dr. Pamela Ray provides to her patients is exceptional. Dr. Ray is a brilliant leader in her field who provides compassionate patient care. She and her staff (Alba in particular who was involved in my surgery) provided me a level of comfort that assisted reducing my anxiety prior to my procedure. I provide Dr. Ray and her staff the highest recommendations.

I have been a patient at Oak Hills Periodontics for quite some time now, and I truly appreciate the level of care and treatment I’ve consistently received. From day one, I have felt welcomed and supported, and over time it has honestly started to feel like I am being cared for by family rather than just a dental team. The entire staff is exceptional, and I especially want to thank Doctor Pamela Ray, Melia, Wendy, and Lupe for their kindness, professionalism, and genuine care. They always go above and beyond to make sure I feel comfortable and informed, and they treat every visit with patience and respect. The doctors and team are highly skilled, but what really stands out to me is the way they combine expertise with compassion. I always feel heard, never rushed, and confident that I’m in good hands. I am truly grateful for the ongoing care I’ve received here. It’s rare to find a practice that makes you feel this valued and cared for over the long term, and I sincerely appreciate everything they do.

I had an excellent experience at this dental office from start to finish. The front desk staff was welcoming, efficient, and made the check-in process smooth. I was seen right on time, which I really appreciated. The dental team was professional, knowledgeable, and took the time to explain everything clearly. They made sure I was comfortable throughout the entire visit and checked in frequently to ensure I wasn’t experiencing any discomfort. Having had extensive dental work most of my life, this was the first time having a pain-free cleaning. This was the first time ever laying in the chair, daydreaming and forgetting that I was even having dental care. 😁🤣 The office itself was clean, modern, and well-organized, which added to the overall positive experience. It’s clear that patient care and attention to detail are priorities here.
