Anyone even with even a small interest in the dental industry understands that laser dentistry is a big thing right now. However, few people understand exactly how laser dentistry works and how it can help. Here are some of the specific ways in which laser is used in dental treatment:

Cutting Through Oral Tissues

One of the primary uses of laser dentistry is to cut through oral tissues. The number of treatments that this can help with is enormous. For example, the laser can be used to cut gum tissues during gum contouring and reshaping to enhance a smile. It can also be used to cut diseases tissue samples so that the sample can be properly examined in the laboratory. The main advantage of laser cutting over traditional instruments is that laser can be precisely controlled, and this reduces the risk of tissue damage.

Vaporizing Oral Tissues

The lasers used in dentistry come in varying intensities. For example, there are extremely intense lasers that can vaporize oral tissues. Such lasers come in handy when the dentist needs to get rid of dead or infected tissues. In this case, the dentist just focuses the laser beam on the relevant tissues and they are vaporized.

Illuminating Dense Oral Tissues

Some dental problems begin under the enamel or deep within the tooth and fester for a long time before rearing their ugly heads outside the tooth. Unfortunately, by then the damage is done and the required treatment is extensive and costly. Fortunately, laser dentistry can be used to illuminate dense oral tissues so that the inside of the tooth can be examined. This technique can be used to, say, detect tooth cavities that are just starting.

Accelerating Teeth Whitening

Laser increases the rate of reaction (reactivity) of hydrogen peroxide. Hydrogen peroxide is the active ingredient in teeth whitening products. This means laser dentistry can help in cosmetic dentistry by accelerating the teeth bleaching process.

Fusing Oral Tissues

Lastly, an appropriate laser can also be used to fuse different pieces of oral tissues. This is more or less like "welding" oral tissues just like different metal pieces can be welded together. For example, the laser can be used to fuse the tiny openings on your teeth's surface to reduce teeth sensitivity.

As you can see, laser dentistry has a huge role to play in dental treatments, and one of its benefits is that is it less painful and less-prone to scarring compared to conventional treatments. Talk to your dentist about laser dentistry the next time you are in for a consultation.
