Tooth whitening is a revolutionary aesthetic dental treatment (aesthetic or cosmetic dentistry) (both because of its enormous demand and because it has been a huge step in the world of dental aesthetics) that reduces the original color of dental pieces by several shades, leaving teeth whiter and brighter.
For this reason, many take much more care of their teeth and there is a growing interest in having white teeth, to the point that a color or tone that was previously considered normal, is now dark; white teeth give a clean, healthy and youthful appearance (this is derived from the fact that people over 50 years of age have a darker shade and a generally more yellowish color).
Dental whitening can be performed in the office or at home, although it is not possible to buy the same treatments (especially in terms of concentrations of active ingredients) for personal use and some specialists warn about the possible damage to dental pieces if they use these in high concentration without the prescription or the follow-up of a specialist dentist.
The whitening of the teeth allows to eliminate most of the stains produced by drugs such as (tetracyclines) or by extrinsic causes such as tea, coffee and other infusions, cigarettes and red wine, among other substances and foods.
However, not all dental stains or obscurations are removable or can be improved through tooth whitening and may require other types of aesthetic dental treatments such as the use of porcelain veneers or covers.
