Start the day with healthy food. The rest of the day may be difficult to control, but breakfast should be easy. Greek yogurt, green smoothies, protein shakes, and eggs and are all examples of super-healthy and teeth-friendly breakfasts. Stay away from sugary cereals and juices and remember to brush your teeth before breakfast and rinse with a fluoride mouth rinse after.
Wait to brush after eating chocolate. After eating, sugar and acid stay in your mouth. These bacteria produce acid which is problematic for your teeth (an acid attack). So, rinse with water after eating sweet sugary foods and avoid brushing for around 30 minutes as this can cause further damage to the teeth surface layer (enamel).
