Let Our Family Treat Your Family

Welcome to Quince Orchard Dental Care.

Here, we think of our patients as extended family, and are honored to contribute to the health and wellness of members from Gaithersburg, Rockville, Potomac and Germantown.

Our dentists are highly accredited, deeply compassionate professionals who offer general dentistry, cosmetic dentistry and pediatric dentistry. No matter your age or the kind of dental service you require, we make it our goal to provide complete and effective care.

Perhaps you've always been one of those people who gets nervous about going to the dentist. We understand. Your mouth is a highly sensitive area that you use to eat, breathe and talk, and any pain or sensitivity can make dental work a less than relaxing event. For patients of all ages we offer varying degrees of relaxation assistance. From the televisions in the rooms to small amounts of nitrous oxide to sedation options, we make your experience as comfortable as possible.

For situations that require more complex attention, we can provide specialized service as an orthodontist, perform the surgery for a dental implant or address periodontal disease. If you've been hoping for cosmetic treatment to make your smile whiter or straighter, we can do that as well.

Some patients struggle with conditions like TMJ, bruxism or sleep apnea. Our dentists have the skill and equipment to treat these types of issues. Ask us if you experience headaches, jaw pain or neck discomfort on a regular basis.

Cleanings, braces or a root canal - we can do it all at Quince Orchard Dental Care. Let our family treat your family in Gaithersburg, Rockville, Potomac and Germantown.

What our patients say

  • Quince Orchard Dental is extremely clean, professional, knowledgeable and friendly. Dr. Mehran Rouhanian and Dr. Lauren Lewis made me feel like I was part of their family. I had a minor but irritating chip on one of my molars and they not only took the time to fix the small chip but also took the time to examine all of my teeth and give me insight to the general health of my teeth, brushing habits, and the conditions of my existing seals and what to look out for. Considering the fact that most people dislike making a trip to the dentist, I was delighted with the entire experience and will definitely be using Dr. Rouhanian and Dr. Lewis again in the future! Thank you!

  • Thank you Dr. Rouhanian for fixing my teeth! I had such a great experience in your office and would recommend it to anyone in the area who needs a dentist is or is looking to make a change. I had several cavaties when I went there and Dr. Rouhanian did an awesome job filling them all. I had no pain at all and now my teeth are no longer sensitive and feel great. Thanks again!

    Omid Gohari, Dental Care

  • We moved from out of town and needed a dentist. Dr Rouhanian and his staff have been amazing. The office staff are professional, courteous and prompt. The office is lovely and up to date. Dr Rouhanian has treated both myself and my spouse and we have both appreciated his expertise. I have also seen his wife Dr Lewis who was also amazing. As an RN I am very particular about our healthcare professionals and would recommend any of our friends to this office. Well done!

The technology is very up to date and the staff is so friendly.They made sure that all of my questions were answered before I left. I have been to multiple dental offices and never felt as comfortable as I do here at Quince Orchard Dental Care.
