The lasers used in laser dentistry have been used for other surgical procedures for over twenty years. Laser dentistry, however, didn't become prominent until the 1990s.
Aside from extreme precision, lasers eliminate the need for cutting and suturing; they also offer rapid recovery, long-lasting results, the ability to safely treat patients with diabetes, blood disorders and those on blood-thinning medications, and minimal or no scarring.
They are most commonly used for gum recontouring and periodontal (gum) therapy.
Some anesthetic is usually required during gum recontouring. Initially, anesthesia may be required for periodontal therapy. A local anesthetic can be used if necessary. Antibiotic therapy is used to prevent infection. As therapy progresses, and gums become healthy, the need for anesthesia generally diminishes.
Your gums may be slightly sore, but most patients are able to continue with their regular activities soon after these procedures.
