Crown lengthening is a procedure on gum and sometimes bone to expose more tooth surface. It is used when a fracture or cavity sits under the gum, or when there is not enough room for a crown without harming supporting tissue.
The name can sound like smile cosmetics. In general practice the main aim is function: a restoration edge that can be cleaned without constant inflammation. The tooth may look longer after healing, and that change is explained before consent.
Is it always possible?
If the remaining root is very short, extraction may be clearer. Dr. Majed Sabbah assesses how much tooth is left before suggesting the procedure in Jabal Al Taj.
