As of 2015, cosmetic laser gum contouring surgery to improve the appearance of a "gummy" smile costs from $300 to $3,000, depending on how much of the gum line needs treatment, according to DocShop. Laser surgery to treat gum disease can cost from $400 to $4,500, states Dr. Max Arocha.
Laser assisted new attachment procedure, or LANAP, and deep pocket therapy with new attachment, or DPT, are FDA-approved laser therapies used to treat periodontal disease, explains Dr. Arocha. To treat and heal gum pockets, the lasers kill bacteria that cause gum disease. Laser gum surgery is typically less expensive than traditional gum surgery, and most dental insurance companies cover a percentage of the cost.
