Dr. Ali Fatemi helms family dental offices in Lexington Park and Gaithersburg, where he practices the techniques that he mastered at the Columbia School of Dental and Oral Surgery in New York. Working with children, adults, and seniors, the doc delivers everything from basic checkups to Invisalign braces. Filtered-water lines run through both offices, carrying bacteria-free fluids for use during biannual checkups and dental cleanings, and an arsenal of digital-x-ray machines cut radiation by 90% compared to conventional systems.

To plug cavities, the doctor forgoes metal fillings in favor of tooth-colored materials that are free of the mercury that some believe can negatively affect health and the chrome that everyone knows can attract insatiable car crushers. Thanks to his license in sedation dentistry, Dr. Fatemi can spare his patients stress by lulling jittery patients into a blissful slumber.
