A laser is a device that uses light energy to perform work. Lasers are unique because they can treat targeted tissue while leaving surrounding tissue unaffected. In addition, lasers may seal off blood vessels and nerve endings during a procedure lessening bleeding, postoperative pain and swelling. Due to their gentle and precise nature, lasers are used with little or no anesthetic.
Lasers in Cosmetic Dentistry
Lasers allow dentists to precisely reshape tissues for the best esthetic results. If a patient has a "gummy smile" or has veneers or crowns, a dentist can lengthen the tooth by altering the hard or soft tissue and raising the gum line with little or no bleeding, pain or postoperative swelling.
Laser whiting is a procedure which is done in the office and takes about one hour. The laser helps speeds up the reaction of whitening gels and works directly off the pigment of the teeth so it can whiten faster and deeper. Most patients see whitening results immediately with results being 3 to 6 shades whiter and with less sensitivity afterward.
Laser use of Periodontal Disease (Gum Disease)
The use of lasers to treat periodontal disease is a conservative, non-surgical procedure. With proper home care, this procedure can often alleviate the problem thus not requiring periodontal surgery.
After removing the debris and calculus (tarter) deposits that are in the pockets around the teeth, the laser is used to selectively remove diseased or infected tissue lining the pockets. The laser will also kill the bacteria that causes periodontal disease and help promote healing of the gums and sometimes even help rejuvenate attachment to the tooth.
Lasers for Cold or Canker Sores
Cold sores can be uncomfortable, unaesthetic and inconvenient. They generally break out in response to trauma or stress. Once the cold sore is full blown, it can take up to two weeks to heal. If the cold sore is caught and treated with the laser before it has a chance to develop, the sore will not break out.. The laser provides immediate relief, and the result will be no further progression of the sore.
Lasers used for Root Canals
Lasers can be used to gain access to the infected nerve and clean, shape, enlarge and sterilize the root canal. If a laser is being used as part of the procedure, the procedure may be preformed without anesthesia, and laser use will also conserve much of the strength and natural tooth structure.
