Sugary, starchy foods and drinks will react to the bacteria in your mouth to produce acid, which will attack your tooth enamel, causing decay and potential tooth loss.
It’s not so much the amount of sugar and starch you eat, but the frequency. If you continually snack and consume sweet drinks throughout the day, you will expose your teeth to acid for longer periods.
Reducing how often you have sugary or starchy drinks and snacks will assists in keeping healthy teeth and gums. Why not replace your sweet treats with cheese, fresh fruit and vegetables, or nuts, and chew sugar-free gum to stimulate saliva production, your body’s natural mouth acid neutraliser. Rinsing with water after eating can also help.
