How safe is teeth whitening?


Teeth whitening is relatively safe according to the majority of studies done in the last 10 years. The in-office teeth bleaching done by dentist, might cause gum or tooth sensitivity, because the whitening gels the dentist use have higher concentration of peroxide, compared to the at home whitening products. Modern whitening gels are better formulated and in general cause less sensitivity than their predecessors.

The stronger whiteners used in dental offices might weaken the teeth enamel, that’s why the in-office whitening gels contain fluoride to counter-effect the possible enamel weakening.
