Lasers deliver energy in the form of light. Depending on the intended result, this energy travels at different wavelengths and is absorbed by a "target." In dentistry, these targets can be enamel, decay, gum tissue, or whitening enhancers.
Each one absorbs a different wavelength of light while reflecting other wavelengths. No measurable effect is seen beyond the intended target site. Lasers are very specific in regard to the wavelength produced.
This means that there must be a different laser for each type of procedure that you want to complete.
There is little or no sound associated with laser treatment, a pleasant treat for the dental patient who has experienced the whine of the dental drill. As technology advances, we hope to see lasers which can be used for several related treatments combined into one convenient machine.
Whitening teeth can be accomplished with special solutions that are applied to the tooth surface in the dental office and activated by laser energy. Colour changes of several shades is possible in a very short time. When combined with at-home tray based whitening systems, dramatic changes can be seen in even the most difficult cases.
Dental lasers have been shown to be safe and effective for treating both children and adults. Very specific equipment and training are required to incorporate this technology into the dental office, and many dentists are becoming involved in providing laser care.
Research with the technology and design enhancements with the machines themselves are proceeding at a staggering pace. At Kasemrad Hospital Prachachuen, Bangkok, Thailand, we look to the future with great excitement as the use of laser energy in dentistry expands to include many more procedures for us to help you and your love ones. |
