According to the Vita scale, teeth can be whitened up to two levels. According to our clinical study, after 7 applications the teeth become up to 7 levels brighter. However, you will see that your teeth are whiter after only one to three days.
The whitening effect lasts up to 18 months. This also depends on your lifestyle habits: The fewer pigment-containing foods and beverages such as coffee, tea, cola, red wine, curry or tobacco products you consume, the longer the effect will last.
If you use a Whitening Toothpaste every day, the whitening effect will not only last longer but will also improve steadily.
