Dentist-Supervised Teeth Whitening
Our teeth are made up of two layers. The outer layer is called the enamel and this enamel serves to protect our teeth from the hazards brought on by everything we put into our mouths. When food, cigarette smoke, coffee, etc. are taken in, eventually, they will form another film-like layer on top of our enamel and in time this film causes discoloration to our teeth.
There are means by which we can help our teeth keep to its original hue such as frequent visits to the doctor for cleaning, and brushing our teeth regularly enough. A dentist can scrape off this film or use chemicals that will wash it away. And we can use special whitening toothpastes at home whose abrassive elements can help knock some of that film away pretty successfully. The problem is, because our teeth are porous, these whitening agents can seep through, penetrating to the inner layer. And when this residue accumulates there and present adverse effects, you cannot simply scour them away.
Stains on the teeth do not suggest rotten teeth but many people just find them unattractive. So if we must address this issue, then we should do so with a system that does not cause MORE problems as a by-product of the solution. In tooth whiteners, bleaching chemicals -- usually carbamide and/or hydrogen peroxide -- are employed to set off an oxidation reaction into the tooth enamel to break apart the staining compounds.
Though these 2 chemicals are the same bleaching elements used to color hair, when used in the mouth the hydrogen peroxide (found in both) is used as the active whitening agent.
Before you start, you must consult with your dental care professional regarding the procedure best for you. Should you decide to go for a Dentist-supervised tooth whitening system, it will involve the controlled application of the two chemicals mentioned earlier in doses especially measured to address your particular needs. Usually, before your dentist will proceed with this, he/she will most likely clean your teeth, fill any cavities, and make sure the your gums are in good health.
Most of these dentist-supervised procedures involve the use of hydrogen peroxide gels, bonded by a high intensity laser light to quicken the bleaching effect. This procedure is said to be able to lighten your teeth four to six shades from the hue prior to the treatment after only one 40-minute treatment.
