What is teeth whitening really everything? The following report includes fascinating information about teeth whitening – info, you can not just old stuff they used to say use.

Teeth whitening, also known as tooth whitening is a common procedure in general dentistry, but especially in the field of cosmetic dentistry. Many people consider white teeth, an interesting feature of a smile be. teeth of a child are generally whiter than the adult teeth that follow. As we age, the adult teeth often increase in value – that is, they darken. This phenomenon is due to changes in the mineral structure of teeth, the enamel is less porous. The teeth may be stained by bacterial pigments, foodstuffs and tobacco.

As white teeth are subconsciously associated with youth, they are desirable. This is reflected in the spread of American culture throughout the world, especially when a white smile is coined a Hollywood smile. “The procedure to bleach teeth uses oxidising agents such as hydrogen peroxide in tooth shade lighter. The oxidizing agent penetrates into the pores in the crystal structure of rod-shaped enamel and s’ interprismatic oxide deposits stain over a period of time, a layer of dentin underneath the enamel, is also bleached.

There are two main methods of money laundering. The first concerns the application of a high concentration of oxidizing agent for a short period of time, which is called office bleach. This provides quick results but risks of chemical burns to the soft tissues. Therefore, most in-office bleaching procedures use a light-cured protective layer that is carefully painted on the gums and papilla (the tips of the gums between the teeth). The bleaching agent is either carbamide peroxide, which decomposes in the mouth to form hydrogen peroxide or hydrogen peroxide itself. The gel typically contains up to 35% hydrogen peroxide equivalent.

The other method uses a thin mouthguard or a low concentration of oxidizing agent next to the teeth as long as several hours a day for a period of 5-14 days of retention. This is called take-home bleaching or in-the-counter. This is a slower process, but has less risk for soft tissue. Bleach is usually less than 10% hydrogen peroxide equivalent.

A typical course of bleaching can produce dramatic improvements in the aesthetic appearance of teeth most colorful, but some spots do not fade. Tetracycline may require prolonged bleaching, as it takes longer for the bleach to reach the dentine layer. decalcifications white-spot can be highlighted and more sensitive.

Recently there have been efforts to accelerate the bleaching process by the use of light. Studies have shown mixed results regarding the effectiveness of light-activated bleaching.

Side effects of whitening teeth as chemical burns (if a high concentration oxidizing agent contacts unprotected tissues, which may discolor the bleach or mucous membranes), sensitive teeth, and overbleaching (known in trade as “fridge-door teeth”). Rebound, or teeth losing the bleached effect and darkening, is also a problem with a number of studies in which the rebound effect over 30 days. A study recent study by Kugel et al showed that up to 4 levels of brightness can be lost more than 30 days with money light-activated/office.
