In order for gums to heal well against a tooth a distance of at least 2-3mm between the margins of the restoration (a cap or filling) and the crest of bone supporting that tooth is needed. If this minimum distance, which is referred to as “biologic width”, is not in place chronic inflammation will occur which could lead to eventual tooth loss.

In addition, a tooth, which is broken or decayed below the gum-line, is difficult for the dentist to restore properly. Crown lengthening provides for better visualization of tooth margins and correspondingly a better fitting restoration.

Crown lengthening is performed under local freezing. A simple crown lengthening involves reshaping of gum and supporting bone to provide better access to the margins. Following a healing period of 4-6 weeks your dentist can proceed with the final restoration of your teeth.
