While traditional dentistry focuses on oral hygiene and preventing, diagnosing and treating oral disease, cosmetic dentistry focuses on improving the appearance of a person’s teeth, mouth and smile. Many people turn to cosmetic dentistry, or ‘aesthetic dentistry’, as a way of improving their appearance. They do this in the same way they might use cosmetic surgery or even a new hairstyle. The treatments can be used to straighten, lighten, reshape and repair teeth. Cosmetic treatments include veneers, crowns, bridges, tooth-coloured fillings, dental implants and tooth whitening.
