Crown lengthening is a procedure that can be performed as a preventative measure against periodontal infections, and is usually implemented in response to repeated infection. It is an effective option for patients who have oversized gums covering a large portion of the crown. They often have problems maintaining their oral health because the extra gum tissue creates many more tight spaces that can trap food, breeding bacteria and infection. The procedure is quite simple. The patient is sedated as the excess gum tissue is surgically removed. As this is happening, our doctor shapes a smooth and symmetrical gum line with significantly less space so that it will be resistant to infection.
