When you put food in your mouth, it immediately meets the bacteria that live there.
Plaque, for example, is a sticky film of bacteria.
These bacteria love the sugars found in many foods. So, when you don’t clean your teeth after eating, the bacteria and the sugar can combine to produce acids, which can destroy the enamel – the hard surface of the tooth.
In time, this can lead to tooth decay. The more often you eat, and the longer foods are in your mouth, the more damage occurs.
Many foods that are nutritious and important in our diet contain sugars – such as fruits, milk, bread, cereals, and even vegetables.
So, the key is not to try and avoid sugar but to think before you eat.
When you eat is also important because each time you eat food that contains sugars, the teeth are attacked by acids for 20 minutes or more.
This means that foods that are eaten as part of a meal cause less harm. More saliva is released during a meal, helping to wash foods from the mouth and reduce the effects of acids.
Here are some tips to follow when choosing your meals and snacks.
It is also important to brush your teeth twice a day and to clean between your teeth daily with floss or interdental cleaners.
And, of course, regular visits to your dentist will help prevent problems from occurring and catch those that do occur while they are easier to treat.
