Tooth decay is closely linked to sugar. Cutting it down in the right way is a simple and effective step to protect teeth.
- Bacteria use sugar to make acid that wears away enamel.
- How often you eat sweet things matters as much as how much sugar you eat.
- Limit sweet drinks and group sweets after meals.
- Keep brushing twice a day with fluoride toothpaste.
Bacteria in the plaque on your teeth use sugar to make acid, and acid is what wears away tooth enamel. So the less sugar you eat, the fewer acid attacks your teeth face. This article suggests a gentle way for the whole family to start cutting down sugar, without being overly strict about it.
Why sugar causes cavities
Each time you eat something sweet, bacteria produce acid for about 20 to 30 minutes. If you snack all day long, your teeth stay in an acidic environment for a very long time and do not get a chance to recover. That is why how often you eat sweet things matters just as much as how much sugar you eat in total.
Where to start cutting sugar
- Limit soft drinks, milk tea and bottled juice, and drink plain water instead.
- Group sweets together after a main meal instead of nibbling all day.
- Read food labels to see how much sugar has been added to a product.
- Swap sweet snacks for fresh fruit, unsweetened yoghurt or plain nuts.
These small changes are easier to keep up than cutting out sweets completely, and they let the whole family take action together. Many families find that once soft drinks are replaced with water, the biggest part of the job is already done.
Habits that go with it
Cutting sugar is not enough on its own. You still need to brush twice a day with fluoride toothpaste and floss every evening. Do not eat sweets just before sleep, because saliva flow drops during the night. For young children, parents can set an example, limit sweets between meals and keep cakes for after meals. If you notice white spots, dark holes or sensitivity, come in early for a check.
