Crown Lengthening

In the section entitled “Perio To Improve Your Smile” we discussed esthetic crown lengthening. Crown lengthening is also done for functional reasons. Sometimes there is not enough tooth structure above the gum to properly restore a tooth. If a restoration is placed under these circumstances the gum can be permanently inflamed leading to bone loss and a crown may continually come uncemented. Crown lengthening is done to expose more tooth structure so that the restoration will be in harmony with the surrounding gum tissue.

Crown Lengthening

When a tooth fractures below the gum line, or if the previous restoration on the tooth ends below the gum line, crown lengthening is necessary. Crown lengthening exposes more of the tooth that is underneath the gum. This allows the dentist to place a new restoration that fits well and does not lead to bone loss.
