Your gum tissue is like a frame that provides the form and the shape of the gingival end of the tooth . Unattractive smile results when the integrity of the gum is compromised or the actual gum between your teeth becomes weak. Usually due to poor oral hygiene (gum disease). Cosmetic dentistry provides many solutions to correct the gum line in order to create a great smile. These solutions are usually part of an overall strategy which may involve cosmetic gum surgery. Used to correct a 'gummy smile' (a significant portion of your gum is exposed when you smile), cosmetic gum surgery is the procedure of lengthening your teeth from the neck of the tooth upwards. Your teeth then appear to be longer and much less gum is seen when you smile.
