Gum contouring, also referred to as gingival contouring or gum reshaping, is a dental procedure that removes or sculpts excess gingival tissue to improve the proportion, symmetry, and overall appearance of the gumline relative to the teeth. It can be performed for purely cosmetic reasons, for functional correction, or as part of a broader restorative plan — and is often completed in a single office visit.
Why It Matters
An uneven or overgrown gumline can make teeth appear short, asymmetrical, or buried — a presentation commonly described as a “gummy smile.” Beyond aesthetics, excess gingival tissue creates sheltered pockets where bacterial plaque accumulates, elevating the risk of periodontal disease. Reshaping the gumline to expose a greater proportion of the natural tooth crown can make home care more effective and support long-term gingival health.
How the Procedure Works
Most clinicians use a diode or Nd:YAG soft-tissue laser, which simultaneously removes tissue and cauterizes blood vessels, reducing bleeding and post-operative discomfort compared to traditional scalpel techniques. The general sequence involves:
- Application of local anesthetic to the treatment area
- Marking of the target gumline to guide tissue removal
- Laser or scalpel excision of excess gingival tissue
- Reshaping of underlying alveolar bone when necessary — a related procedure called crown lengthening
- A short recovery period during which hard, crunchy, or spicy foods should be avoided
Candidacy and Key Considerations
Ideal candidates have stable bone levels and no active periodontal disease. When only soft tissue is removed, results are typically permanent, since excised gingival tissue does not fully regenerate. In cases involving significant bone overgrowth, osseous recontouring may be required alongside soft-tissue reshaping to prevent the gumline from migrating back — a process known as creep. Gum contouring is frequently combined with restorative and cosmetic work such as dental veneers or composite bonding to achieve comprehensive smile improvement.
A consultation with a periodontist or experienced restorative dentist is the best starting point for determining whether gum contouring addresses a cosmetic concern, a functional deficit, or both — and for confirming that underlying periodontal health is sufficient to support the procedure.
