How a Laser Accelerates the Laser Teeth Whitening Process

Laser teeth whitening is an effective way to remove stubborn stains. Dentists use a laser to speed up the whitening process. This is the controversial part of laser teeth whitening. Surgeons use this energy source to remove growths or cauterize wounds. That is why some people are wondering how a laser helps speed up laser teeth whitening. Here are the details.

Using a laser as an energy source in laser teeth whitening

Many companies in the field of dentistry continue to develop ways on how to improve the appearance of teeth. One of these methods is teeth whitening. An increasing number of people are becoming more aware of the color changes in natural teeth. That is why the demand for teeth whitening continues to increase. This treatment is one of the biggest fields of aesthetic dentistry.

The current teeth whitening techniques use 20-35% hydrogen peroxide. Chemical reactions in the whitening process can speed up by using several sources of energy. These energies go through a LED light, plasma arcs, and halogen lamps before reaching the whitening gel. Dentists are now using laser as a brand-new energy source. They combine laser with whitening gels, and something better comes out each time.

Using laser technology results in laser teeth whitening. Laser makes the teeth whitening process shorter. It only needs two to three minutes. This is much shorter than using conventional lighting methods.

Laser teeth whitening results in lower levels of tooth sensitivity as well. Other conventional lighting techniques have a strong acid reaction in the form of swelling. Laser teeth whitening gives better results. Its effects also last for a longer period.

What laser teeth whitening does

Laser teeth whitening heightens the teeth bleaching process without changing the chemical and structural changes to the tooth’s enamel and its surrounding tissues. Laser speeds up hydrogen peroxide activation in whitening gels. As soon as the hydrogen peroxide absorbs the laser, it breaks down. It becomes a radical of oxygen and a particle of water.

The radical of oxygen shrinks the enamel’s larger organic chromophores into smaller components through quick oxidation. Laser also heats up the whitening agent. This deepens the pigment bleaching. It is possible by penetrating deeper into the dentin layer. Dentin handles the coloration of the tooth. Once the bleach penetrates the stains in the dentin, teeth whitening happens.

In-office laser teeth whitening

Dentists perform laser teeth whitening in the clinic. This treatment uses 15-40% hydrogen peroxide. This type of teeth whitening has quick, visible whitening effects. It is minimally invasive and does not need the participation of patients.

Laser teeth whitening is for patients who need a dentist’s supervision because of conditions like gingival recession. Laser decomposes hydrogen peroxide faster to create free radicals. These free radicals whiten the teeth. The interaction of laser and hydrogen peroxide improves teeth whitening effectiveness.
