Anatomical crown exposure and crown lengthening procedures are used when your periodontist must adjust the levels of gum tissue and sometimes bone around a tooth. These procedures may be performed for esthetic or functional reasons.
Anatomical Crown Exposure
Anatomical crown exposure is used on patients whose teeth appear too short, or their gum line is uneven or “gummy”.
During anatomical crown exposure, your periodontist removes excess gum tissue and sometimes bone tissue to expose more of the tooth crown, the white enamel-covered part of the tooth. Once the excess gum and tissue is removed, the gum line is then sculpted to create a more correct proportion between gum tissue and tooth surface. This can be done to just one tooth to even out your gum or to several teeth to expose a natural and broad smile.
Your dentist or periodontist may recommend dental crown lengthening to make a restorative or cosmetic dental procedure possible. When a tooth is decayed or broken below the gum line or has insufficient tooth structure for a restoration, such as a crown or bridge, crown lengthening allows your periodontist or dentist to adjust the gum and bone level to expose more of the tooth so it can be restored.
