Unfortunately, not all dental bleaching techniques are safe. Some providers use too high a concentration of hydrogen peroxide, which is not even allowed in Belgium and the Netherlands because it damages tooth enamel. At Wellness Kliniek, we use the PrevDent treatment, a safe and comfortable method to painlessly whiten teeth up to 9 shades. There's no need to worry about damaging tooth enamel, as the technique is completely safe to use.
