Cosmetic dentistry involves a variety of aesthetic and restorative dental treatments including dental bonding, gum contouring, porcelain veneers, teeth whitening, bridges, crowns, fillings and implants. Cosmetic dentistry can be performed to make the teeth more pleasing in appearance as well as rejuvenate the look of the mouth. These procedures can also be performed for functional reasons to restore the bite of the patient and improve oral hygiene.
