Cosmetic gum surgery is a treatment often used in tooth correction such as veneers, bonding or crowns. This treatment is needed when gum tissue deteriorates or becomes damaged due to genetic factors, gum disease or poor oral hygiene habits. Problems treated by cosmetic gum surgery include a gummy smile, gum recession, jagged gum line, gum loss. This weakens the gums, which can alter the appearance of a smile. Cosmetic gum treatment is done by dental surgeons and cosmetic dentists.
