4. Keep drinks in your mouth for a long time

The longer you keep sour drinks in your mouth, the more damage they cause. Acid does not mean that such drinks taste sour: in (light) soft drinks, fruit juice, yoghurt drinks and wine are acids that you barely taste. Let your wine roll extensively in your mouth or keep your cola in your mouth until the jab is off, then the acids are extra long in your mouth and the chance of erosion is greater.

Not too often drink, those sour drinks. With water, coffee and tea without sugar you are always good. Drink soft drinks or fruit juice, swallow it immediately or drink with a straw.
