While lasers still seem like science fiction, they’ve been used commercially (and medically) for decades. But there’s still room for growth in practical applications with this developing technology. One promising area is in the treatment of periodontal (gum) disease.
Gum disease is a bacterial infection triggered by plaque, a thin film of bacteria and food particles caused by inadequate oral hygiene. The disease is highly destructive and can eventually lead to both tooth and bone loss. Treatment procedures vary widely, but they all have the same goal: remove the offending plaque and calculus (tartar) from tooth and gum surfaces. Without plaque the infection subsides and the gums can heal.
For decades now, dentists have removed plaque and calculus manually with special hand instruments or ultrasonic equipment. If the disease has advanced below the gum line or formed deep voids filled with infection called periodontal pockets, the dentist may also employ surgical techniques to access the infected areas.
While all these techniques have a long track record for effectiveness, they can cause the inadvertent destruction of healthy tissue, as well as create discomfort for some patients afterward. This is where a new protocol called Laser Assisted New Attachment Procedure (LANAP®) may be able to make a difference in the future.
With the LANAP® protocol, surgeons direct a laser beam of light through a fiber optic the width of three human hairs onto diseased tissue. The particular color of light interacts with the tissue, which contains the darkly-pigmented bacteria causing the disease, and “vaporizes” it. The beam, however, passes harmlessly through lighter-pigmented healthy tissue; as a result diseased tissue is eradicated with little to no harm to adjacent healthy tissue.
With these capabilities, trained dentists using LANAP® for gum disease treatment might be able to achieve conventional results with less tissue removal and bleeding, less discomfort for patients, and less tissue shrinkage than traditional procedures — and without scalpels or sutures. And some post-surgical studies have indicated LANAP® might also encourage gum tissue regeneration in the months following.
LANAP®, however, is still developing and requires further research. Thus far, though, the results have been encouraging. As laser technology advances, it’s quite possible tomorrow’s patient may experience less discomfort and more effective healing with their gum disease treatment.

Periodontal (gum) disease is potentially devastating to your teeth, gums and bone. To fight it we have to remove the substance that causes and sustains the disease from all oral surfaces — a thin layer of bacteria and food particles known as plaque.
To accomplish this task, we use a variety of hand instruments called scalers to mechanically remove plaque and calculus (hardened plaque deposits), as well as ultrasonic equipment to vibrate plaque loose and flush it away with water. If we detect plaque deposits well below the gum line and around the tooth roots, we may need to use other techniques like root planing or surgery to access these deeper areas.
Â While gum disease is persistent and aggressive, these traditional techniques have proven quite effective in controlling the infection and restoring health to diseased gums. Yet like other aspects of medicine and dentistry, technological advances have created a new option for gum disease treatment: the Nd:YAG laser.
The Nd:YAG laser is named for the crystal it uses to produce a narrow and intense beam of light on a specific frequency. In recent years it's become an important surgical tool because it can distinguish between diseased and healthy tissue, destroying the former while not affecting the latter.Â It's being used now on a limited basis for treating gum disease, especially for removing infected tissue in deep pockets that can form below the gum line, and for removing plaque and calculus from root surfaces.
Â Because of its precision, early evidence of effectiveness is encouraging: minimal tissue damage and swelling, less bleeding and reduced patient discomfort after treatment. The heat from the laser has also been shown to kill bacteria and essentially sterilize the area.
Still, the findings aren't conclusive enough as to whether lasers are superior in most circumstances to traditional scaling methods. For the time being, we'll continue to use the tried and true methods for removing plaque and calculus. But as laser technology advances, the time may come when this new approach to gum disease treatment will become a more prominent and beneficial option for patients.

Lasers have transformed our everyday lives, especially in healthcare. These intense beams of light of a single wavelength have revolutionized all manner of diagnostics and treatments, from general surgery to cosmetic therapy.
Dentistry has also been influenced by the laser revolution. Here are just a few of the areas where they’re growing in use and popularity.
Early disease detection. Laser instruments can take advantage of “fluorescence,” the tendency of bacteria to “glow” when exposed to certain wavelengths of light. This is proving more effective in detecting early tooth decay in pits and fissures (very tiny areas in a tooth’s biting surface) than traditional needle-like probing instruments called dental explorers. Newer lasers can now detect the same fluorescent qualities in soft tissues, which may reduce the detection time for oral cancer and make the difference between life and death.
Dental caries treatment. Lasers have become an alternative to the dental drill in treating teeth with dental caries (decay). Although with larger cavities lasers are somewhat slower than the conventional drill, they truly shine when it comes to early enamel caries and small cavities because they can be quite precise in the amount of tooth structure they remove. This feature allows them to be less invasive than a dental drill.
Periodontal treatment. Periodontal (gum) disease is an infection caused mainly by bacterial plaque and calculus (hardened plaque deposits) that have adhered to tooth surfaces. Lasers are emerging as an alternative to conventional periodontal (gum) surgery to treat voids or spaces below the gum line called periodontal pockets that have formed because of gum tissue detachment as supporting bone is lost. With their ability to target and destroy infected tissue without damaging nearby healthy tissue, lasers can achieve similar outcomes as traditional techniques but with less tissue damage and discomfort to patients afterward.
Research and development into laser technology continues to perfect these and other applications that promise to make dental procedures less invasive and more comfortable for patients.
Root canal treatments are an essential part of dental care — countless teeth with deep decay would be lost each year without it. Now, this traditional dental care procedure is advancing to a new level of precision through lasers.
Root canal treatments have a simple goal: access a tooth's infected pulp and root canals, clean out the infected tissue and fill the empty pulp chamber and canals with a special filling. Once filled, the access is sealed and a porcelain crown later placed for additional protection against re-infection.
In the traditional procedure, we perform these steps manually with a dental drill and hand instruments. We may also need to remove a good portion of tooth structure, both healthy and infected tissue. A laser, on the other hand, is a highly focused beam of light with the ability to interact with healthy and infected tissues differently: destroying infected tissue while having no effect on nearby healthy tissue. The end result: we may be able to remove less healthy tissue with lasers than with the conventional procedure.
Lasers are also helpful with softening and precisely molding the filling material within each canal's particular shape. And, early reports seem to indicate a higher degree of comfort for patients (less drill noise and need for anesthesia), less bleeding and faster recovery times than the conventional approach.
But as a tool for root canal treatments, lasers do have a couple of disadvantages. While light travels in a straight line, root canals are rarely straight — conventional instruments with curved designs usually accommodate odd canal shapes better than a laser. Lasers can also raise temperatures within a tooth that can damage healthy tissue, both within the pulp and outward into the dentin.
Still, lasers for root canal treatments appear promising with some dentists using a combination of lasers and manual techniques to garner benefits from both approaches. While you won't see lasers replacing the traditional root canal treatment anytime soon, the future looks bright for more efficient ways to treat deep tooth decay.
Since their development in the laboratory over five decades ago, lasers have found increasing use in our everyday lives. In the field of medicine, it’s not uncommon to find lasers in the offices of dermatologists, ophthalmologists and surgeons, to name just a few. Now, some dentists are finding that lasers can offer an alternative means of treating gum disease — and one that may have advantages in certain situations.
You probably know that a laser produces a special kind of light — in fact, its name is an acronym for “Light Amplification by Stimulated Emission of Radiation.” Essentially, a medical laser uses electrical energy to produce an intense and narrow beam of concentrated light. This light can be directed to a particular area, often via a fiber-optic channel. The laser’s precision allows a doctor or technician to focus the light energy exactly where it’s needed — to remove diseased tissue, seal off blood vessels, and sterilize a wound, for example.
For several years, periodontists — dentists who specialize in treating diseases of the gums — have been researching the use of lasers for treating certain types of gum disease. In standard clinical practice, hand-held instruments and ultrasonic cleaning tools are used at regular time intervals (3 – 6 months) to remove the sticky bacterial biofilm, as well as calculus (tartar), that forms in between teeth and gums. If that still isn't effective, gum surgery may be required to access the affected area, remove diseased tissue, and reduce pocket depth (the space below the gum line that gets larger as bone loss occurs) to prevent reinfection.
Recently, however, several new procedures have been developed that use lasers to accomplish some or all of these goals. One type of therapy uses a special laser that emits pulses of light with a specific wavelength (color) of 1064 nanometers. This light passes through healthy cells like a sunbeam through a window — but when it encounters darkly-pigmented bacteria, it vaporizes them instantly!
One of the potential advantages of laser treatment is its precision: focused directly on the area where trouble occurs, it targets diseased tissue but leaves healthy tissue alone. Another is that laser treatment is less invasive: It requires less tissue removal, and may cause less discomfort and tissue shrinkage (gum recession) than conventional periodontal surgery. And because it produces small amounts of heat, it can seal blood vessels and help control bleeding.
While lasers have long shown promise for treating gum disease, until recently it wasn’t clear if they offered any advantages over traditional methods. Now, several studies have shown that certain laser treatments can be just as effective as traditional gum surgery in many cases — with the potential benefit of being less invasive. In the future, the use of lasers for periodontal procedures is likely to increase.
It’s important to remember that no single treatment — not even a laser — can “zap” gum disease in one fell swoop. Controlling periodontal disease requires effective at-home oral hygiene combined with regular professional care.
