Thu-Nga Ortega, DDS, MAGD

At Dental Cosmetix only one patient is seen at a time to ensure the best quality of care is given to every individual patient. This also allows for close monitoring of each patient’s teeth and early detection of any problems to help yield the best and most conservative treatment, thus avoiding the need for complex dental treatment. Due to Dr. Ortega’s extensive post graduate studies and credentials, most treatment can be done in our office without referral to other offices thus allowing us to closely monitor patient treatment outcome.

Dr. Ortega is known by many as one of the best dentists in Fairfax. Through her extensive post-graduate studies and the use of cutting-edge technology, Dental Cosmetix has become the premier cosmetic dental facility in Fairfax, Virginia.

Our family has been having Dr. Ortega at Dental Cosmetix provide outstanding dental care for over 15 years. She is extremely generous with her time in making sure we get the best care and has even come in on the weekend to treat emergencies. We are always confident that we receive the highest quality care each and every visit. Dr. Ortega’s cheerful and uplifting attitude provides a positive atmosphere and makes our family feel comfortable as patients.

I am probably the wrong person to rate dental practice because I’m inherently biased! Yes, I love dental cleaning and scrapings! And, Dr Ortega is one the best! She and her caring staff are all so professional and friendly. Dr. Ortega listens to my concerns and never rushes me. I feel like I’m in good hands when I see her. If you have had the unfortunate experience of being with a “bad” dental practice then Dental Cosmetix is the right place for you!!!!
