About Spring Valley Orthodontics

Dr. Negaar Sagafi is praised for a watchful, non-aggressive approach that avoids rushing kids into early or unnecessary braces.

Reviews highlight Dr. Negaar Sagafi's patient-centered style, including a willingness to monitor younger kids for years before starting treatment rather than pushing early braces, and accommodating urgent or unscheduled visits. Several notes mention fast results with newer technology like Brava and Brius appliances, and families with multiple children in treatment often return across years. Staff are described as warm, and the office is noted as clean and well organized across its two locations.

Bethesda/Spring Valley Orthodontics. ​Dr. Sagafi and her team provide a top-tier orthodontic experience, blending advanced technology with attentive, individualized care. Highly recommended for their expertise and welcoming environment, specifically noted for making the transition into adult braces a positive and supported journey. Dr. Sagafi went above and beyond to help me!

I am a young 50 plus year old patient:) My teeth have been so messed up since I was young, that Dr. Sagafi had to coordinate a treatment plan that involved a periodontist, orthodontist, and general dentist. She installed my brava braces, but alot had to happen prior to that. I am about 2 years into my treament. I have received so many nice compliments on my teeth. And my smile has greatly improved with no cosmetic dentistry. I have to admit that Dr. Sagafi and her staff have been nothing but Graceful, Patient, Professional and Most Competent in my experience. Highly recommend her services, Kudos!

I cannot say enough wonderful things about this practice! Dr. Sagafi is not only an extremely knowledgeable practitioner, but she also has such a warm and welcoming bedside manner. I used to live in Washington DC and moved to Colorado, however, I chose to travel back to DC to have Dr. Sagafi do my adult Invisalign because I have 100% confidence in her abilities. She and her staff worked with my hectic schedule and were able to fit me in at this location and their other office in Bethesda. Dr. Sagafi was also really great about putting the bonds on the inside of my teeth so they weren't visible, which is so great! Everyone at this office is so warm and welcoming, you won't have a bad experience!

Dr. Sagafi is brilliant, creative, compassionate and wholly committed to her patients. She and her staff provide truly excellent care, time and time again. We came in with a highly unusual and complex presentation, requiring several years to manage and coordination with several other practitioners. At every step on the journey. Dr. Sagafi listened, brainstormed various alternatives and stayed upbeat and committed. We always felt cared for, understood and like she was doing everything she could to deliver the best care in a dynamic and challenging case. We are deeply grateful to her and her team.

Dr Sagafi is great! I was a little apprehensive at starting orthodontic treatment as an adult, especially because I was told I would likely require jaw surgery. But Dr. Sagafi was able to come up with a way to treat me without requiring surgery. My regular dentist says Dr. Sagafi is a cutting edge orthodontist and the best in DC and I believe him. Dr. Sagafi's entire team is great too-scheduling is always a breeze as were all billing and insurance issues.
