Laser Dentistry

Laser dentistry, a modern alternative to the drill, provides the same results and is often preferred by the patients. As lasers become more common in daily life, dentistry is one more area it has expanded to.

What is laser dentistry?
Lasers provide energy in the form of light at various wavelengths. The energy is projected to its intended target that then absorbs the light. Each target absorbs light at a different wavelength and deflects light outside of this range. This is why it is important that a different wavelength is used for each specific procedure.

Is it safe?
The use of lasers has been reported to be safe on all patients, both young and old. There are varying wavelengths that are used to get the desired effect. If a wavelength that is too strong is used for the wrong procedure it can damage the tooth or tissue, therefore, precaution should still be exercised.

What can they be used for?
Lasers can be used for almost any dental procedure, including the common root canals, tooth decay (cavities) and even teeth whitening. They can also be used for crown lengthening and removing excess tissue in the middle of the upper jaw, between the lip and teeth. It can also be used to cut the tissue that results in a child being "tongue tied". The procedure is much more appealing to the parent and child because the laser is a small object, there is relatively no blood, and no pain or noise. One thing lasers are unable to be used on are amalgam (silver) fillings. They are unable to cut through the amalgam restorations, but can be used on newly formed cavities.

Why are lasers preferred?
If used properly, lasers can lead to less blood, swelling and discomfort. Laser dentistry eliminates the grinding sound of the drill that is often annoying and leads to many people's phobia of the dentist. Lasers project no sound and nearly cause no pain or discomfort. The use of anesthesia can be eliminated from most procedures, but can easily be administered if pain does occur. Eliminating the anesthesia is popular among patients because they are able to return to work right after their visit without a numb lip or tongue.

Dare I say, "welcome to the new age of dentsitry"? I think that as the laser becomes more common and more research is conducted, lasers will be able to completely remove the drill, and hopefully the fear of patients as well.
