The “crown” is the part of a tooth visible above the gumline. Sometimes more of the tooth below the gums must be exposed to fill a cavity near the gumline or place a new crown on a broken tooth. “Crown lengthening” provides more tooth structure for this to to be done. This helps to ensure that the general dental procedure is successful and prevents gum irritation.
The periodontist administers a local anesthetic and gently recontours excess gum and bone tissue to expose more of your natural tooth.
