1. Brush your teeth twice a day
Brush your teeth last thing at night and at least one other time during the day with a fluoride toothpaste. When brushing at night time, spit out after brushing and do not rinse so that the fluoride stays on your teeth longer and protects them even more.
2. don't brush after eating
After eating or drinking any acidic food, wait at least one hour before brushing your teeth. Acidic food and drink, such as juices, smoothies and fruit, temporarily soften your tooth enamel. Try not to brush straight after eating these things, or you could end up damaging the protective layer on your teeth. Drinking a glass of water immediately after acidic food/drinks dilutes the acid and helps minimise erosion of your teeth.
