Laser Dentistry

Laser Dentistry

Laser dentistry is one of the most advanced dental treatments today. WaterLase uses a patented technology that combines focused light energy with a stream of water for a highly precise, exceptionally gentle dental experience. Using Laser Dentistry, Dr. Kumar performs a wide range of procedures with benefits including:
• Faster healing time and less trauma to teeth and gums.
• Less anesthetic for most procedures.
• Treating dental needs in more than one part of the mouth in one visit.
• Making dental care a more relaxing experience for you.

The Benefits of Waterlase Dentistry


WaterLase dentistry uses laser energy and a gentle spray of water to perform a wide range of dental procedures without the heat, vibration and pressure associated with the dental drill. With many procedures, it’s possible to use less anesthetic, or no anesthetic at all.


A laser dentist can often get you in and out of the dentist chair faster, since it’s less likely that you’ll need an injection. It’s nice to avoid that shot, isn’t it?

Not using anesthetic can allow Dr. Kumar to perform procedures that used to require more than one visit in a single appointment. Also, we can perform procedures that once meant an additional trip to a specialist, saving you even more time.


A laser dentist can remove decay far more precisely than the drill. This saves more of the healthy parts of your tooth and avoids micro-fractures that the friction of a drill can cause.

Saving your natural teeth can save you the discomfort and cost of bridges, dentures and implants. Even better, studies show people with natural teeth live longer.

What Can WaterLase Dentistry Do?

We may use WaterLase dentistry laser to treat your gums or other soft tissue in your mouth to:


We may suggest contouring or shaping your gums using WaterLase dentistry to improve the appearance of your smile – safely removing excess gum tissue that may give you a “gummy” smile, or make your front teeth appear irregular in size or shape.


Quickly and safely remove growths or excess tissue in your mouth including gum tissue over an unerupted tooth, small “tags” called papilla, and growths called fibromas.


Connections that restrict the movement of your tongue or cause your gums to recede can be “released” with less post-operative pain.


We recommend using WaterLase dentistry to remove debris and bacteria between your teeth and gums that can cause bleeding gums, gum recession and even loss of teeth. For moderate to severe gum disease, ask your doctor about REPAIR minimally invasive periodontal treatment.

We may also use our WaterLase iPlus laser to perform other procedures that could benefit you.

Frequently asked questions about Dental Lasers?

What is a dental laser and how does it work? ?

A dental laser produces a very narrow, intense and coherent beam of light energy which may or may not be visible to the human eye. When laser light and energy is absorbed by human tissues, it causes a reaction. The beam of light produced by the laser has the ability to cut, clean, remove, vaporize, and/or shape soft tissues (gums, cheeks and tongue) or hard tissues (removal of tooth decay).

How do lasers remove tooth decay?

Tooth structure contains water, and the laser is absorbed by water inside tooth. The laser energy causes the water to boil instantly and the resulting steam pressure removes the decay. Since diseased or decayed material has higher water content than the healthy tooth structure, the decay will be targeted first and removed.

What are the advantages of using dental lasers as compared to using a dental drill in removing tooth decay?

There are several different types of lasers that can be used to remove tooth decay, harden the newest types of cosmetic filling, finding tooth decay without putting sharp instruments on the tooth and may often help your dentist to conserve and strengthen healthy tooth structure.

  • Lasers used for removing tooth decay often reduce or eliminate the need for a local anesthetic
  • The laser can be minimally invasive than the drill in removing decay because of its selectivity for the softer, darker, decayed tooth structure
  • The laser can be used to remove new decay that occurs around existing gold and porcelain crowns
  • If the decay extends below the gum line, a laser can gently contour the gum so that the tooth and gum can be restored to health. Using a dental drill in this area could cause bleeding difficulty in bonding procedure
  • Lasers do not cause vibrations like conventional dental drills do. Some individuals don’t like the sound of conventional drills
  • Lasers do not cause micro fractures which a conventional drill might cause. Micro fractures might cause future tooth/filling fractures
  • Certain types of lasers can be used to detect decay without taking X rays like Diagnodent

What are the other uses of lasers in dentistry?

Yes. The lasers can be used for many dental procedures. These may include: the correction of speech problems caused by a tongue-tie which prevents normal tongue movement; the exposure of partially erupted wisdom teeth which reduces pain; the removal of lip pulls often seen in both young and adult orthodontic patients due to high frenum attachments; and the gentle removal of swollen gum tissues caused by medications you must take to correct or control medical problems. A laser may also perform biopsy procedures by taking small tissue samples for diagnostic purposes. Lasers can reduce inflammation in gum tissues within a periodontal pocket and reduce the amount of bacteria so that gums can heal. During crown lengthening procedures, lasers can remove or reshape excess gum tissues and bone tissue to provide adequate tooth shape for properly fitting restorations. Check with your dentist about how lasers can be used in your dental treatment. Small laser devices can also be used now a days to detect dental decay.

Can lasers be used effectively to whiten teeth?

Yes. Laser energy can activate the whitening chemical gel that can be used to whiten teeth. The usual procedure is to coat the tooth structure with the whitening gel and then the laser light is directed onto it. The activated chemical gel brightens your smile.

Do lasers hurt?

The aspect of laser dental or gum surgery that most people appreciate is its comfort. While no treatment is painless, the laser may reduce the need for postoperative pain medication and may reduce swelling and bleeding. Lasers usually result in faster healing as well.

How long laser dentistry been around?

Lasers have been used in Dentistry since 1990. The U.S. Food and Drug Administration has determined that lasers provide safe and effective treatment of a wide range of dental procedures.

When you visit our office, will you always be treated with laser?

Not always. Although the laser is a very useful dental instrument, it is not appropriate for every procedure and situation. It is frequently used in conjunction with other instruments. Please ask Dr. Kumar or your hygienist about the role of laser therapy in your dental treatment.
