It is not just what you eat that matters. It is also how often you eat.

Every time you eat or drink something sugary, your teeth are under acid attack. This can last for up to an hour. If you snack frequently, your teeth have little time to recover.

Grazing throughout the day can:

• Increase the risk of tooth decay.

• Weaken enamel.

• Raise the chance of sensitivity.

• Make plaque harder to control.

Sugary drinks, sweets and even some “healthy” snacks can contribute.

To reduce risk:

• Stick to three meals a day where possible.

• Keep sugary food and drinks to mealtimes.

• Choose water or milk between meals.

• Pick savoury snacks when you can.

If you do have something sugary, try to have it with a meal rather than on its own.

Chewing sugar-free gum after eating can help increase saliva, which protects teeth.

Small changes in eating patterns can protect your smile. Giving your teeth time to recover is just as important as brushing.
