Spencer G. Hornstein, DDS, MAGD
Dentistry of Bethesda
Dr. Spencer G. Hornstein founded Dentistry of Bethesda on Old Georgetown Road in 1991 and still leads the practice today. He holds Mastership in the Academy of General Dentistry and is a Fellow of the Academy of Laser Dentistry.
Why patients choose Dr. Hornstein
The MAGD credential is worth understanding when you are shopping for cosmetic work. Cosmetic dentistry is not a recognized dental specialty, so the honest proxies for skill are continuing education, case volume, and photographs. Mastership in the AGD requires more than 1,100 hours of continuing education, several hundred of them hands-on — a documented, verifiable record of training rather than a marketing claim. Patients cite a stable, long-tenured team and a practical, low-pressure approach to elective treatment.
Practice focus
Cosmetic bonding, porcelain veneers, tooth contouring and smile makeovers, laser dentistry, and comprehensive general and restorative care.
