Another type of lightening enamel, which is produced in the dentist's office, is Air-flow. This procedure is not a complete bleaching, and the usual cleaning of dental plaque.
Laser Whitening Features
Этот процесс в основном похож на предыдущий.Here, a special gel is also applied to the teeth, but its activation is performed using a laser. Naturally, laser teeth whitening, the price of which is significantly higher than the cost of household products, is considered one of the safest methods.

Home methods
Despite the fact that today there are safe and effective methods of teeth whitening, some people continue to use old-fashioned recipes.
Such means are considered very popular:
