Dental work is often just as conspicuous as the flaws it's attempting to fix. That's why Dr. Mark Nguyen continues Orange Dental Arts' 30-year tradition of conservative dentistry. Rather than relying on silver metal amalgams to keep cavities in check, he fills enamel holes with white composite resin, which, like a snowman's skull tattoo, is difficult to see. Similarly, his Invisalign braces ease teeth into place without wires or brackets. Dedicated to utilizing the most conservative dental technology available, Dr. Nguyen attends continuing-education courses.
