Teeth Whitening
The white teeth are synonymous with youth, beauty and good health. For this reason, teeth whitening procedures there since time immemorial. In the past resorted to the use of all types of abrasives to remove stains and rinse to get the color of teeth. Today we know better not use any product, since we wanted to whiten the tooth without harming it.
Why darken your teeth?
The color of the teeth is determined by the individual characteristics of dentin, therefore some people naturally have whiter teeth than others. There are other factors that influence the color of the teeth, the most important are:
* The consumption of certain foods or beverages, dyes, wine, herbal tea, coffee, tea and snuff cause the enamel surface stains.
* Some medications such as tetracycline, chlorhexidine or fluoride can stain the enamel and dentin
* Due to the aging darkens the dentin and enamel layer thins by wear, so that the tooth tends to be more yellow.
* The blows can cause bleeding inside the tooth structure that will make the tooth turns a grayish-black.
How does the whitening?
The outermost part of the tooth, the tooth enamel, it is colorless and therefore the tooth color is determined by the color of dentin that is below the tooth enamel. Whitening products act penetrating through the enamel to bleach the dentin and is important not to damage the enamel because otherwise they would leave the tooth checked out and looks off, without translucency and ultimately lifeless.
Stains can be classified into grades according to their intensity and the causative agent of browning. When the spots are superficial, such as those caused by snuff for example, may disappear with a simple dental cleaning. For deeper stains need to use specific products of bleaching.
The substances used today are carbamide peroxide and hydrogen peroxide in different concentrations and formulations. Both substances are considered safe if used in correct doses and times and always under supervision of a dentist. These products get a chemical reaction of oxidation that causes the tooth clarify its color without affecting the structure of tissues. The effect of bleaching is permanent, although the teeth can become darker over time, because logically continue to be exposed to the factors we have listed above. In general it may be necessary to repeat the treatment after a few years.
Attention …
! It is important to note that many severe stains (especially those caused by use of tetracyclines, which have gray or even blackish bands of different intensities) can not be resolved by bleaching. In these extreme cases will have to resort to the use of ceramic crowns made in zirconium, which offer an opaque white base, allowing us to disguise the staining of dentin and achieve impeccable results.
! Whitening treatments do not change the color of ceramic prosthesis, or the resin or the composite, therefore the color of the restorations in the mouth there will remain the same following treatment and will be darker or yellow over to natural teeth bleached, so it will be advisable to change them once you have achieved the desired target. For this reason it is important that you have to undergo some form of rehabilitation in his mouth (crowns, veneers, etc), do after bleaching, and get all the teeth have a uniform color.
