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.

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.
For years, lasers have revolutionized the medical industry and now they are beginning to do the same within the field of dentistry. However, anytime new technologies are introduced, people naturally will have questions. Here is a list of frequently asked questions (FAQs).
What is a laser?
Lasers are beams of light that are a single wavelength and color. Laser is an acronym derived from “Light Amplification by Stimulated Emission of Radiation.”
How are they different from regular sunlight?
White light is made up of light with many wavelengths corresponding to the visible spectrum comprising the rainbow (red, orange, yellow, green, blue, indigo, and violet). Laser light consists of beams of a single color and hence a single wavelength of light, concentrated to a high energy level, which can penetrate living tissue.
How are they used in dentistry?
Dental laser usage typically falls into three categories: disease diagnosis; soft tissue procedures of the gums, lips and tongue; and hard tissue procedures of the bone or tooth enamel and dentin. Examples of the most common hard tissue treatments include the diagnosis and removal of tooth decay, while the most common soft tissue treatments include the removal of gum tissue as it relates to cosmetic dentistry and the treatment of gum disease.
Are they safe?
Absolutely! Before blazing a trail in the field of dentistry, lasers have been used for years in the medical field with research evidence and the FDA approving both their safety and efficacy. In fact, they are minimally invasive and can result in less tissue removal, less bleeding and less discomfort for patients after surgery. And what could be better than that?
