Welcome to Rashin T. Bidgoli, DMD, PC & Associates

“Rooted in Care, treated like Family”

Welcome to Dr. Bidgoli & Associates in Potomac Falls, VA formerly known as Sterling, VA.! Our mission is to make a conscious effort to treat every patient as if they are a member of our own family. We often say, “If you were my mother, father, or daughter, this is what I would do.” That’s the mindset we carry into every appointment. It’s not just about fixing a tooth- it’s about doing what’s truly best for the person sitting in front of us, with honesty, care, and respect. Dr. Bidgoli & Dr. Majlessi believe in taking as much time as needed to listen to your concerns.

What truly sets us apart in the Northern Virginia area is our commitment to precision and collaborative care, a reputation we have earned through the years of honest, patient-focused care. Many patients come to us for second opinions, seeking clarity and reassurance before moving forward with treatment. It’s not uncommon for them to share that their general dentist told them, “If Dr. Bidgoli’s office says you need a root canal, that means 110 percent you need it.” That level of trust- from both patients and referring doctors speaks volumes.

At our practice, we use state-of-the-art 3D imaging technology called CBCT to get a clear, detailed view of your teeth—helping us detect even the smallest cracks, hidden canals, or signs of infection. What makes us different? We go a step further. Unlike most practices where clinicians interpret the scans themselves, we send 95–97% of our CBCT scans to a board-certified oral and maxillofacial radiologist, Dr. Abramovich, for interpretation. His expertise ensures that we receive a comprehensive, medically validated radiology report for each case. This high level of diagnostic rigor allows us to provide our patients with the most accurate, informed, and safe treatment possible—setting a new standard in endodontic care.

Services we offer include Root Canal Therapy, Root Canal Retreatment, Apicoectomy, Cracked Teeth,Cone Beam Captured Tomography (CBCT)and more. We look forward to providing you with prompt and effective treatment in our office.

We hope you find this website useful and invite you to contact us with your questions at any time.

Yesterday, I had a root canal done by Dr. Majlessi. I dont normally write reviews but wanted to share my experience. Like me, you probably have anxiety about getting a "root canal". But put those worries aside. This office was AMAZING from start to finish! The Office Manager - Cindy, was so kind & helpful with getting me in for treatment quickly as I was in pain. The assistant, was also so sweet & clearly cares about the patients comfort at the office. Dr. Majlessi was wonderful. She has a great bedside manner & constantly checked on me through out my procedure to make sure I was doing OK. My procedure was quick, painless & I am feeling so much better today! If I could give 10 stars I would.

Had my first root canal ever with this team and I felt cared for and communicated with clearly throughout the whole process. Thank God for modern medicine as well to avoid what could have been excruciatingly painful. They dentists made sure the anesthesia had numbed to the area for the procedure and then throughout the procedure, they were attentive to making sure I didn’t experience pain and that I was cared for. I was shocked at how calm the whole experience was and grateful to still be able to complete work later that day and received clear instructions on care. Thank you for your good work!
