Every time you eat, your saliva breaks down food particles to prepare them for the digestive process. One of the results of that break-down is an acidic byproduct, which fuels dental plaque. Each time you eat, the acid lasts for about half an hour inside of your mouth.
So in theory, snacking more frequently can raise your risk of cavities. Especially with certain types of foods. Sugar being one, but carbohydrates being another.
Drinks like diet soda and sports drinks are just as — if not more so — dangerous to your tooth enamel as a naturally sweetened soda.
If you have more dental plaque on your teeth, your mouth will be creating even more biofilm byproducts each time you eat. So brushing your teeth throughout the day can help you lower your risk of decay, along with less frequent snacking.sugar
