Teeth bleaching has become a standard dental procedure over the last decades. From the beginning of dental bleaching there was a belief, that UV-light enhances the power of the material used (hydrogen peroxide).
Recent studies have actually shown, that the use of light cannot increase the bleaching efficacy. On the contrary, they initiated some skepsis, since the light can increase the drying out of the treated teeth, often leading to irreversible vitality issues.
We offer both procedures. We strongly advise you though, not to choose UV-lighting, as long as it isn’t absolutely clear, that it produces no harm to the vitality of the teeth.
