CONTOURING
What?
-
It is the trimming of the gum line by either laser or periodontal surgery.
-
Gingivectomy is the cutting away of soft tissue only, in such a way that the firmer outer layer of the gum is preserved as far as possible.
-
Crown lengthening involves opening of the gum and contouring of the underlying bone with a drill. The gum is trimmed and sutured into the correct position.
When?
-
An uneven gum line
-
Too much gum covering the teeth eg. Overgrown gums, due to side effects of certain medications or genetic defects
-
Teeth that appear too short
-
“Gummy smile”
-
Where a crown needs to be placed, but very little tooth is left.
-
Severe periodontitis
Advantages
-
Good cosmetic result, with minimal invasion.
Disadvantages

It extends total treatment time, as aesthetic treatment can only be started after healing of the gums.
