A cosmetic dentist is responsible for a variety of procedures — from minor fixes to major surgeries. Here are a few of the cosmetic procedures they offer. Teeth whitening is one of the most basic cosmetic dentistry procedures—as well as one of the least expensive. Over time, teeth can become stained from food, drinks, medications, or other habits like smoking. Many people turn to teeth whitening to make their smile brighter. Dental veneers are thin, white shells made from medical-grade porcelain, resin, or ceramic. They’re custom made for each patient to resemble their natural teeth. A dental crown, also known as a dental cap, fits over a decayed or damaged tooth. These crowns can keep a weakened tooth from breaking or used cosmetically to cover misshapen or severely discolored teeth.
