Cosmetic gum surgery, also known as periodontal plastic surgery, is a type of dental surgery that aims to improve the appearance of the gums and, in some cases, the overall smile. This type of surgery is often performed by periodontists who specialize in treating gum-related problems.

Below are some common cosmetic gum surgeries:

• Gum contouring: correction of the "gummy smile" 
• Gingival Grafts: to address receding gums by adding gum tissue to areas where it has receded.
• Crown Lengthening: when there is not enough dental structure available for restorations, excess gum tissue is removed
• Laser Gum Contouring

These procedures are often performed for both functional and aesthetic reasons. While the primary goal is to address issues related to gum health, aesthetic improvements can have a significant impact on a person's smile and overall facial aesthetics.
