A preventative measure against periodontal infections.
There are preventive measures against. One method implemented in response to repeated infection its called crown lengthening. The procedure is an effective option for those patients who have excessive gum tissue which covers a large portion of the tooth. Patients who have extra gum tissue often have problems maintaining their oral health. The excess tissue causes tight spaces between teeth where food can be trapped—breeding bacteria and infection. The procedure is quite simple. The patient is sedated then the excess gum tissue is surgically removed. Then the trimmed tissue is shaped to create a symmetrical gum line with significantly less space, making it resistant to infection.
