Thy B. Nguyen, DDS
Crown Dental Care
Dr. Thy B. Nguyen is a general and cosmetic dentist at Crown Dental Care in Rockville, MD. Born in Vietnam and raised in Gaithersburg from the age of eight, he treats patients in English and Vietnamese — so a crown, a root canal, or an implant plan can be explained in the language a family actually thinks in.
Background and training
Dr. Nguyen earned a Bachelor of Science in biology from The George Washington University before completing his Doctor of Dental Surgery at the University of Maryland Dental School in Baltimore. He graduated at the top of his class, was selected for the Gamma Pi Delta Prosthodontic Honor Society, and was elected president of the Gorgas Odontological Honorary Society, a merit-based organization.
He went on to complete a residency in advanced general dentistry in Baltimore, where his colleagues elected him chief resident and he received the Harry W. Dressel Jr. Award, given for clinical proficiency and total patient care.
Why patients choose Dr. Nguyen
That residency is worth weighing when you compare general dentists. It is an additional year of hospital-based training past dental school, concentrated on complex restorative cases and patients with medical complications — the background that makes a general dentist comfortable keeping work in-house that would otherwise be referred out to a specialist.
Patients most often see him for cleanings, consultations, bridges, root canals, and dental emergencies, and he carries a 4.93 out of 5 overall rating on Zocdoc. He is recognized as a top dentist in the Maryland region and has appeared as a dental expert in the TOP Doctors Interviews series carried on CNN, FOX News, and CNBC.
Practice focus
