Trusted, Proven

Great staff. Everyone is positive and very helpful. The doctor spends time with you discussing any condition and the options for treatment. I've been going there for years, and have always had good service.

The practice’s periodontist has magic in her hands. I have had so many procedures done (bone grafts, augmentation, implants, etc.) over the last two years, and I never needed to take a painkiller after the procedures. I was able to heal very quickly with very little pain. She’s very friendly, explains the procedure well and puts you at ease. She always has a sunny disposition, and she even provided me with her mobile number once so I could get in touch if needed during the weekend. Luckily, I never had to! Dr. Kwon was responsible for my crown. From my first experience with him, I loved how he explained the whole procedure and was extremely through and gentle during the procedure. He took the time to explain the aftercare and followed up, too. Great care overall! The staff is also extremely friendly and very responsive. Check-in and check-out are quick and easy. They work closely with your insurance, payment plan, etc., and they are quite upfront about the costs so you can plan better.

For as long as I can remember, I’ve been a ‘grinder;’ I grind my teeth during the day and also at night. While my teeth were straight and have healthy roots, my grinding had eroded and they were beginning to crack. My lower front teeth—the most visible in my smile—were nearly gone. I was ashamed of my teeth. Over an 8-month period, Dr. Valle-Cintron was a constant in a series of visits during which I had a full restoration of my teeth. He always took the time to listen to my concerns, answer my questions and explain what he was doing. The doctor and his assistants always made a high priority of maintaining my comfort—and the quality of their work and their professionalism are commendable. The friendly and efficient staff was always helpful and accommodating. The periodontist, who performed my bone graft and placed an implant where I’d had an extraction prior to my first visit, has her practice in the same office—truly convenient. After Dr. Valle-Cintron installed the permanent upper crowns, I realized I wanted the brightest white for my teeth and had made the wrong color choice. Dr. Valle replaced the crowns at no charge—a noble effort on his part for which I am most grateful. I’m very happy with my result. Dr. Valle-Cintron is intelligent and articulate. He’s a highly skilled cosmetic dentist who makes his patient feel comfortable and does a really good job of explaining the treatment process. His prices are fair and reasonable. He’s patient, pleasant and easy to be around. I have a new smile. I no longer feel like hiding my teeth while talking. It’s definitely given me more self-confidence.
