Crown lengthening (or crown exposure) is required when your tooth breaks at or below the gum line and needs a new crown or other restoration. The edge of the crown is deep below the gum tissue and not accessible. It is also usually too close to the bone or below the bone.
The procedure involves adjusting the level of the gum tissue and bone around the tooth in question to create a new gum-to–tooth relationship. This will allow your general dentist to place the edge of the crown at the gumline, ensuring a proper fit to the tooth. It should also provide enough tooth structure so the new restoration will not come loose in the future. This allows you to clean the edge of the restoration when you brush and floss to prevent decay and gum disease.
When the procedure is completed, sutures are placed to help secure the new gum-to-tooth relationship. You will need to be seen in one or two weeks to evaluate your healing.
