Q: How are lasers used in dentistry?

What our experts say:

There are different types of lasers that do different things.  Diode lasers are used on soft tissue only. Sometimes we use it to contour gum tissue, to help get rid of periodontal pockets, to take away gum tissue where there is excess growing over a wisdom tooth; to get rid of an abscess ulcer; and to get rid of sensitivity on a tooth.  We also use a BIOLASE WaterLase iPlus. It’s an Erbium laser used for soft tissue as well as cutting hard tissue and removing decay. It’s used instead of a drill, so the laser energy chips away at the tooth structure. You don’t need an anesthetic, 95 percent of the time, which means no needles. This means we can work on multiple areas in the mouth at once.  It can also be used for root canal work to cleanse and disinfect bacteria, and can also be used to trim bone in periodontal bone surgery. I am a laser-assisted dentist. We use it all day long.  Most of the time, we use the WaterLase.  I try to stay on the cutting edge and am the first in my area to have been trained with the water laser.  I’m doing a lot of gum surgery with it, instead of using burs and scalpels. The healing is amazing with it. It disinfects as it cuts, so there is minimal or no bleeding, and many times sutures are not necessary. But, you need to get a mastership to learn how to use the laser.  It’s a whole new world.
