In orthodontic treatment, teeth are moved in to new positions and relationships and the soft tissue and underlying bone are altered to accommodate changes in esthetics and function. Function is more important than esthetics. The speciality of orthodontics has in addition to its benefits, complications as well as risks associated with its procedures. However the benefits outweigh the risks & complications in most of the treatment cases. Few of the unwanted side effects associated with treatment are tooth discolorations, enamel decalcification, periodontal complications like open gingival embrasures, root resorption, allergic reactions to nickel & chromium as well as treatment failure in the form of relapse.

A pleasant smile is considered a symbol of beauty and well being in the modern society periodontology extensively deals with soft tissue surgeries. However, pain, trauma, bleeding, postoperative edema and scarring are often associated with conventional methods of surgery which are problematic for both the patient and the clinician. Hence, to overcome these drawbacks, 940 nm diode laser was used to perform various periodontal surgical procedures. This case report highlights the use of diode laser to correct gummy smile for better shape, contour and gingival margin.

The toxicity and tissue reactions to dental materials are receiving more attention as a wide variety of materials are used and as federal agencies demonstrate more concern in this area. A further indication of the importance of the interaction of materials and tissues is the development of recommended standard practices and tests for the biological interaction of materials.

The principal reason of gingival inflammation is bacterial plaque, along with other predisposing factors. These predisposing factors are calculus, malocclusion, faulty restorations, complications associated with orthodontic therapy, self- inflicted injuries, use of tobacco & radiation therapy. The contributing factors to gingival inflammation & periodontal destruction are deficient dental restorations and prosthesis. Inadequate dental procedures that add to the weakening of the periodontal tissues are referred to as iatrogenic factors.

Lasers have been used in dentistry since 1994 to treat a number of dental problems. A variety of lasers are now available for use in dentistry. Once stated as an intricate technology with restricted usage in clinical dentistry, there is a growing awareness of the usefulness of lasers in the armamentarium of the modern dental practice, where they can be used as an adjunct or alternative to various long-standing approaches.
