Your smile looks more like a smirk. You keep your lips taut over your teeth, uncomfortable with their yellowish hue and convinced that your far-from-white smile is far less attractive than going through life with your mouth shut. You wish you could smile a big, uninhibited grin. You want to be free of that self-conscious feeling you get every time you look into the mirror. You're thinking about laser teeth whitening.
Laser teeth whitening is a popular procedure for those who feel like their smiling with corn kernels instead of pearly whites. It can produce tremendous changes in coloration and the fact that its administrated by a dental professional adds a level of safety that you do not have when applying chemical mixtures to your mouth at home.
Among the many different processes available, laser teeth whitening produces some of the best results. How does it work?
It starts with your dentist applying a coating of a peroxide-based chemical mixture to your teeth. The hard shell of you teeth, the enamel, is actually quite porous on a microscopic level and those chemicals can penetrate into the dentin. The dentin, your teeth's interior, is the primary source of coloration. A yellowed dentin results in a yellowed tooth. By getting a bleaching agent inside the tooth, it's possible to fundamentally alter its coloration.
That explains the whitening agent itself, but what about the laser? What purpose does it serve? The dentist can use a laser to heat the agent, improving its performance and heightening the whitening reaction it spurs. In laser teeth whitening, the laser does not actually do anything to the teeth. It activates the bleaching agent. It makes the process quicker and allows the dentist to achieve more dramatic results.
The use of these chemicals is safe, but there are potential side effects for some people. Nerve irritation and inflammation can cause temporary discomfort for recipients of laser teeth whitening. While criticism will argue that this whitening can actually weak one's teeth, that argument is resolved by the fact that your dentist will immediately treat your cleaned teeth to a fluoride wash, adding to its strength in excess to any weakening the chemical process may have caused.
When the laser turns off and the bib comes off, the results of laser teeth whitening can be quite impressive. People often move up several shades on the whiteness scale. People who have not cut loose with a big grin for as long as they remember find themselves smiling with a newfound sense of self-confidence. They're able to look happy when they're happy and they can stop wondering if they're being judged on the basis of a dingy grin. Laser teeth whitening improves lives by improving smiles.
