Sonrisa más brillante: Blanqueamiento dental profesional I


With age, the teeth naturally darken because the shade is determined by the color of the dentin, and it darkens because as the enamel ages, it becomes more translucent and reflects the tone we really have inside. However, the main causes are due to the frequent consumption of foods with coloring properties such as coffee, tea, wine, carbonated drinks, etc. Smoking is also included in the category of factors that darken the tooth, as well as poor oral hygiene.

In addition, another factor inducing dental darkening is the consumption of tetracyclines, these antibiotics causing dental discoloration. In the latter case, teeth whitening is not as effective.

Either way, the dentist is responsible for identifying where the dental darkening is coming from and recommending the most appropriate treatment for each case.

  1. Teeth whitening at home: This treatment is generally complementary to the previous one.

Ideally, any autonomous treatment should be supervised by specialized dentists.
  1. Mixed teeth whitening: it consists of a combination of the previous two.

Teeth whitening, according to specialists, does not weaken the enamel, it can only cause sensitivity in the teeth and gums, but it regenerates without leaving a trace once the treatment is complete and it does not occur in all cases.
