Sarah Mir, DDS
Associate Pediatric Dentist
Dr. Sarah Mir recently moved to Connecticut and is excited to have joined the team at The Little Tooth Company. She was born and raised in Long Island, New York but has spent the last few years working in Washington, DC. She received her bachelor's degree from New York University, and went on to graduate summa cum laude from Stony Brook School of Dental Medicine, where she received her Doctorate in Dental Surgery. Following dental school, Dr. Sarah completed an additional two years of training in pediatric dentistry at NYC Health + Hospitals/Woodhull in Brooklyn, NY. Her education includes treating children with special needs, dental phobias, and the medically compromised. After completing her training, Dr. Sarah became a board certified pediatric dentist through the American Board of Pediatric Dentistry.
While in dental school, Dr. Sarah travelled to Madagascar where she treated children with no access to dental care. This experience solidified her decision to become a pediatric dentist. She is committed to making every dental visit fun for both the patient and parent.
Dr. Sarah loves baking, traveling, and reading. She can't wait to meet you at your next visit!
