A crown (‘cap’) is often indicated for teeth with very large fillings, or after a tooth has fractured. A crown lengthening procedure is required in situations where the tooth fractured below the gum, or when there isn’t enough sound tooth structure remaining to support the new crown.
This procedure involves the removal and re-contouring of the tissue surrounding the tooth. Lowering the gum-line around the tooth provides your dentist with more sound tooth structure to place the crown on. Your crown will have a better prognosis and the gum tissue will remain healthy.
Aesthetic crown-lengthening involves a similar procedure, typically in the upper front teeth. The procedure is indicated to reduce excessive gum tissue surrounding the teeth in order to improve a ‘gummy smile’ appearance and restore more harmonious proportions to the upper front teeth.
