Best Teeth Whitening

Laser and Tooth Dehydration

A common adverse effect in majority of teeth whitening treatments, especially when integrating ultra violet light-activated processes is tooth dehydration. In tooth whitening, heat is part of the process.

With heat, the water substance contained by the teeth and the nearby tissues evaporates, resulting to whiter-looking teeth. Typically, a few days later, rehydration takes place in which the teeth revert to a darker shade. Realizing this occurrence, one may speculate what the effect of quick in-office whitening really is.

Could it just be tooth dehydration and not a genuine lightening? Is laser treatment not the best teeth whitening choice after all? During a laser teeth whitening procedure, a highly concentrated light is aimed at the tooth. The tooth whitening agent on the tooth’s surface boil offs. Some of the peroxide permeates into the tooth and facilitates real bleaching. As the tooth is illuminated, the dark areas especially the pulp chamber and dentin attract light more willingly than reflect it.

Light is absorbed and transformed into heat. Gradually, the internal heat mounts up, pushing the fluid out of the tooth via the protein matrix encasing the basic units of the enamel. Looking at the tooth’s composition, it is porous, thus it is permeable.

For similar reason, it permits the peroxide to diffuse and allows water to move out of it. The whole process makes the efficiency of laser a bit confusing. The intention to move peroxide into the teeth to cause actual teeth whitening can be defeated when fluid moves out of the teeth after directing light to the tooth for peroxide activation.

The ending is, teeth become dehydrated and look white for the time being. Later, the teeth take in water like a sponge, thus returning to a darker shade. More info and facts about different teeth whitening solutions are available at http://www.bestteethwhiteningsolutions.com.
