In questions about your teeth, we cooperate with the DentAL dental practice , which has its headquarters directly in our practice.
The natural aging process of the teeth also changes their color over time. Typical triggers for discoloration are tobacco, tea, coffee, red wine, cola and some medications. The whitening of the teeth (bleaching) causes nothing else than the destruction of these dyes.
The active ingredient used is always hydrogen peroxide, H 2 O 2, whether with over-the-counter strips (here, however, the concentration is lower), rails or active substance applied directly to the teeth.
Hydrogen peroxide was once used to disinfect the oral cavity and by chance one came across the coveted effect of tooth whitening. The unstable H 2 O 2 decomposes into water and reactive oxygen, which splits and destroys dyes.
Please note that fillings and ceramic restorations (eg crowns) can not be lightened.
