Periodontics: Uses of Periodontic Dental Lasers
Since their introduction in the 1960's, laser use in medicine and dentistry has increased steadily, and it's been no different in Periodontics. The CO2 and the Nd:YAG lasers have both received Food and Drug Administration (FDA) approval for soft tissue surgery and are the most commonly used lasers in dentistry. A dental laser work by delivering concentrated beams of light strong enough to cut through tissue.
Pros & Cons of Dental Lasers
The popularity of lasers results from claims that dental laser gum treatment is painless. Although the FDA has not permitted the manufacturer of any laser to make that claim, the general experience described by patients is that there is less pain and swelling after laser treatment compared to conventional oral surgery. Local anesthesia for pain control is still required during laser surgery.
Another advantage of the laser is that it causes less bleeding in the area of surgery than traditional oral surgery techniques. This is especially helpful in the oral cavity, which has an abundant blood supply. The laser decreases bleeding by sealing the blood vessels at the surgical wound. On the flip side, this can delay healing and create a less stable wound.
Application of Lasers in Periodontal Treatment
The application of lasers in periodontal treatment is restricted to the removal of gum tissue to reduce pocket depth, or for some minor periodontal plastic surgery procedures. These surgeries can be easily performed with traditional instruments without the additional high cost of dental laser treatment.
More recently, lasers have been evaluated for use in scaling and root planing. But in a research study recently published in the Journal of Periodontology, laser therapy appeared to be less effective than traditional scaling and root planing treatment. In fact, research has not conclusively shown that laser therapy is effective in removing the tartar that has accumulated under the gum line and can actually damage the surfaces of teeth and the bone. This damage could delay healing and the ability of the gum tissue to reattach to the root surface.
For all these reasons, the American Academy of Periodontology is concerned about misleading claims regarding the use of lasers in periodontics. It is important to remember that laser treatment in periodontics is limited to soft tissue (gum) for periodontal surgery and that the laser beam should not touch the tooth or bone. Anesthesia is required during dental laser treatment, and dental laser treatment may be more expensive than traditional surgical procedures.

Receding Gums Fixed With Periodontal Procedures
Not even the most beautiful teeth can look attractive if healthy and pleasing-looking gums do not surround them. That's because the gums frame the teeth like a picture frame frames a picture. To have a pleasing smile, the shape, color, and texture of the gums are just as important as that of the teeth they frame. Although tooth development, periodontal disease, trauma, or tooth loss can create esthetic gum deformities like receding gums, modern periodontal procedures can give individuals a smile to smile about.
Common Cosmetic Gum Problems
Unhealthy Gums
As a result of periodontal disease, a person may have red, shiny, or swollen gums. If an individual has gingivitis or periodontitis, the gums have to be periodontally treated prior to cosmetic dental procedures.
"Gummy Smile"
Teeth that appear too short may be normal-sized teeth hiding under too much gum. This can be the result of normal tooth development, or the use of certain medications that may cause gums to overgrow. Either way, a crown lengthening (see article "Crown Lengthening") procedure can help reveal the normal tooth structure.
Recession
If the teeth appear to be too long or if the root surfaces are exposed, it may be due to receding gums (see article "Recession"). Soft tissue grafting (see article "Soft Tissue Grafts") is very successful in correcting this problem.
Uneven Gum Margins
If the gum margins appear to be higher on some teeth and lower on others, this may be due to receding gums, altered eruption, or gum defects that resulted from tooth loss. The treatment of uneven gum margins may require crown lengthening, soft tissue grafting, ridge augmentation or a combination of these procedures.
Gum Indentations
After a tooth is lost, the bone that encased it disintegrates and the gum around it may collapse, creating an indentation where the tooth used to be. Ridge augmentation procedures can help correct this problem.
Uneven Pigmentation
Changes in the color of the gums may be part of normal gum development, or the result of scarring. Soft tissue grafts can predictably correct this problem.
Spaces In Between the Teeth
Periodontal disease can result in spaces in between the teeth that may appear like black triangles. These spaces can be very difficult to treat. They can be made less unattractive by a combination of procedures that include orthodontics (braces), crowns (caps), and/or periodontal (gum) surgery. The best way to avoid these spaces is to seek periodontal treatment in its early stages.
Missing Teeth
One or more missing teeth can be predictably replaced with the aid of dental implants. Dental implants can look and feel like natural teeth.
Changes in the appearance of the gums like receding gums can occur as a result of normal tooth development, periodontal disease, trauma, or tooth loss. By working with a restorative dentist who has expertise in cosmetic dentistry and through the aid of modern periodontal techniques, individuals can design a smile that is both aesthetic and youthful in appearance.
