How to fight tooth decay and erosion
Drink soft drinks only in moderation, if at all.
Use a straw so your teeth are less exposed to the sugar and acid in the drink.
Take a drink of water, preferably tap water that has been fluoridated, after a sugary or acidic drink to help rinse out your mouth and dilute the sugars.
Protect your teeth by using fluoride toothpaste. Also, after drinking sugary or acidic beverages, don't brush your teeth right away. Wait at least one hour so your teeth can recover and your enamel can reharden before you take the brush to them.
Do not sip a sugary or acidic drink slowly or over a long duration. Doing so exposes your teeth to sugar and acid attacks for longer.
Never drink sugary or acidic drinks before you go to bed – if you do so, the liquid will pool in your mouth, coating your teeth with sugar and acid.
Drink water instead. It has no acid, no sugar – and no kilojoules.
