Crown Lengthening
In a procedure known as crown lengthening, your periodontist can extend the height or size of the portion of the tooth that is visible above the gumline. For the stability of your crown, there must be enough tooth structure for it to hold it in place. When your tooth has broken down, or when tooth decay has extended below the gum line, crown lengthening can reduce the gum tissue and bone level in order to gain better access to your tooth.
