Every time you eat or drink something sugary, bacteria in plaque turn the sugar into acid. Acidic food and drinks also attack enamel directly, even without sugar. Over time, repeated acid attacks lead to decay and erosion.
Decay and erosion
- Decay is caused by bacteria feeding on sugar. It creates holes (cavities) in the tooth.
- Erosion is the dissolving of enamel by acid from food and drinks. It makes teeth thin, sensitive and yellow-looking.
Common culprits
- Fizzy drinks, including diet versions, which are still acidic
- Energy drinks and sports drinks
- Fruit juice and smoothies
- Flavoured water and iced tea
- Sweets, especially sticky or slow-dissolving ones
- Frequent sweetened tea or coffee
Habits that limit damage
- Keep sugary and acidic food and drinks to mealtimes.
- Drink water between meals.
- Use a straw for fizzy drinks to reduce contact with your teeth.
- Don’t sip drinks slowly over a long time.
- Wait 30 minutes after something acidic before brushing.
- Finish a meal with cheese or milk, which help neutralise acid.
Hidden sugars
Many sauces, cereals and “low-fat” foods contain added sugar. Check labels for ingredients ending in “-ose” (sucrose, glucose, fructose) and for syrups.
Regular check-ups
Early decay and erosion can be managed before they cause pain. Book a check-up with Dr H.B Mohamed in Lenasia on 011 852 7866.
