How Laser Teeth Whitening Works

Sphere: Related Content
Laser teeth whitening is a relatively new teeth whitening system. Teeth whitening treatment is used in cases where normal brushing, flossing and other means of dental hygiene don’t work as they should. Over time, the enamel of teeth tends to erode due to the foods we eat and the liquids we drink. The modern American diet is very high in sugars and starches, and many of our drinks contain lots of citric acid or carbonated water, both of which eat away heavily at tooth enamel. Tooth enamel is the substance that coats our teeth to prevent them from decay. Laser teeth whitening is one method to get rid of the built-up stains and plaque.

The Process of Laser Teeth Whitening

First, the teeth are scraped as clean as they can possibly be with conventional instruments like picks. This is to lessen the work the laser process has to do during laser teeth whitening. Next, a coating of hydrogen peroxide or other bleaching agent is lightly applied to the teeth near the gum line. This is basically preparatory work for the actual laser to do its job. After the initial coating of peroxide is applied in laser teeth whitening, a slightly heavier coat of chemical-based gel is put on the teeth. The gel is to ensure that the laser is able to perform as well as possible and remove as much plaque as can be done. The next step in laser teeth whitening is the actual laser – it works in conjunction with the gel and peroxide, rather than as a stand-alone agent. Most of the time, the entire process takes approximately an hour. It’s worth the wait – laser teeth whitening can whiten teeth by up to 10 shades.

If you have sensitive teeth, they can be damaged by the laser, though this only happens rarely. However, you may need to repeat the process of laser teeth whitening several times to get the full effect. People with sensitive teeth would be best advised to do the entire treatment in one session to avoid using the gel, because it sometimes can have a bad reaction with teeth. Laser teeth whitening can cost anywhere from 300 to 2000 dollars, depending which system is used.

Laser teeth whitening is a good process by which to clean teeth, and it can be the most effective over a long term. Depending on your own preferences it can be done either quickly or slowly, but take care not to become over-reliant on treatments and neglect good hygiene habits.
