The money for a smile
The technique of tooth whitening is done when the stains are internal (age, color genetics ...) and that scaling is not sufficient to mitigate them.
If now the products and methods used fully respects the integrity of the enamel, other considerations come into play, and the laundering operations must be well reasoned. The color of teeth is related to pigmentation of the skin, color of lips and gums. Even cleared up, the smile must always be in harmony with the rest of the face. This is the first impression a person emerges, it must be fully adapted to the morphology and even personality.
The Hollywood smile was his time. He smiles now be customized. The practitioner must also consider well the interest of clarification. If the tooth has flaws, they will only be more visible once it cleared. There has been a whole decade several techniques that elucidate the enamel and restore luster to the teeth. They have improved considerably since their inception and can now get a very natural color without causing major side effects.
The technique
The most common is the "home bleaching". Your dentist makes a groove in soft plastic, adapted to your teeth, in which you place a freeze most often based on hydrogen peroxide. You then apply the splint on your teeth and keep overnight for three weeks. This same technique can be done in the office. The product is then more concentrated (it goes from 22 to 35%), the application takes 25 minutes and three to five sessions are required, at a rate of one every 15 days. A new method more effective and performed in the office has been developed. This deposit of hydrogen peroxide to 35% in a groove that keeps it strong on the teeth and is placed under a UV lamp. The results are even more convincing. With all these techniques bleaching, teeth brightened by about one or two colors and the effect lasts about 5 years, but avoid beverages and tobacco yellow teeth, have good hygiene Dental and make regular cleanings.
Disadvantages
The only side effect observed is hypersensitive to hot and cold can be treated by taking tablets of fluoride after bleaching.
Price
600 to 1 600 $ depending on the color of the teeth and the technique used.
