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.

We’ve developed a number of effective treatments for periodontal (gum) disease. Depending on how far and deep a patient’s infection has advanced, treatment can be quite invasive and even require surgery. The more invasive, the longer and more uncomfortable the healing process can be.
But using a medical laser could make that less so. Although its use for gum disease treatment is still in its infancy, the latest observations from the field seem to show patients undergoing laser treatment may have less tissue trauma and bleeding, less discomfort after the procedure and quicker healing times.
Gum disease is a bacterial infection mostly caused by dental plaque, a thin film of food particles that build up on teeth in the absence of effective oral hygiene. The infection can advance deep below the gum line, weakening gum attachment to teeth and destroying supporting bone. Ultimately the affected teeth can be lost.
Traditionally, the only way to stop the disease is to manually remove plaque buildup on teeth and gum surfaces, which is continuing to sustain the infection, with special hand instruments called scalers or ultrasonic equipment. Because it’s important to remove as much plaque and diseased tissue as possible, we may need to perform a surgical procedure called flap surgery to move some of the gum tissues out of the way to get to these deeper areas. As with any surgery, this can create tissue trauma that may cause discomfort during the healing process.
Our new alternative is to use an Nd:YAG medical laser in a procedure known as Laser Assisted New Attachment Procedure or LANAP. With light energy delivered through a small fiber no more than the width of three human hairs, the laser can pinpoint diseased tissue and destroy bacteria through intense heat. Because of the laser beam’s tiny width and pulsing action, healthy tissue is at less risk for trauma than with the traditional treatment.
Coupled with other techniques, LANAP procedures could remove as much infected tissue and plaque as traditional methods, but with less healthy tissue trauma. In the future, then, patients with advanced gum disease undergoing laser treatment could have less bleeding and discomfort and faster healing times.

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.
