When you eat or drink sugary foods, bacteria in plaque convert the sugars into acids. These acids attack tooth enamel, causing demineralization and, eventually, cavities. Sticky sweets and sugary drinks prolong acid exposure because they cling to the teeth or bathe them in sugar for extended periods. Over time, repeated attacks lead to sensitivity, decay and possible tooth loss.

Understanding free sugars

Health experts recommend limiting “free sugars” to less than 10 % of your total daily energy intake, and ideally below 5 %. Free sugars include sugars added to foods and drinks by manufacturers or at home, plus those naturally present in honey, syrups and fruit juices. They don’t include sugars found in whole fruits and vegetables because the fibre slows absorption and reduces harm to teeth.

Tips to reduce sugar and protect your smile

1. Choose water: Replace pop, juice and sports drinks with water. Sugary beverages are a leading source of free sugars, and sipping them throughout the day constantly exposes teeth to acid.
2. Use a straw: If you do indulge in a sweet drink, use a straw positioned toward the back of your mouth. This reduces contact with your teeth.
3. Limit frequency: It’s not just how much sugar you consume, but how often. Having a dessert with a meal is less harmful than snacking on sweets all day. Frequent snacking means teeth are under constant attack.
4. Rinse or drink milk after sugary treats: Swishing with water helps wash away sugars and acids. Milk neutralizes acids and supplies calcium and phosphate to remineralize enamel.
5. Read labels: Many foods marketed as “healthy” are loaded with added sugars. Check ingredients for words ending in “‑ose” (such as sucrose or glucose) and keep track of total sugar grams.
6. Choose whole fruit over juice or dried fruit: Whole fruits provide vitamins and fibre without bathing your teeth in concentrated sugar. Dried fruits and fruit juices are sticky and high in free sugars.
7. Don’t brush immediately after acidic or sugary foods: Acid softens enamel temporarily. Wait at least 30 minutes before brushing to avoid abrasion. Rinse with water instead.
8. Maintain good oral hygiene: Brush twice daily with fluoride toothpaste, floss daily and visit your dentist regularly. Fluoride strengthens enamel and helps reverse early decay.

Reducing sugar is a powerful way to protect your smile and overall health. Small changes add up over time and can prevent cavities, gum disease and other complications.
