A dentist is a healthcare professional trained to diagnose and treat oral health conditions. A cosmetic dentist is a dentist who specialises in improving the appearance of teeth and gums. Cosmetic dentistry procedures include teeth whitening, porcelain veneers, bonding, and gum contouring. Some cosmetic dentists may also offer Invisalign clear braces and teeth straightening. The main thing that differentiates a cosmetic dentist from a dentist is their extra training in cosmetic dentistry procedures. This means that they can offer a broader range of treatments to help improve the appearance of your smile.
