First foods and cavity risk in the first 3 years
15 August 2026 · 5 min read
What, when and how often a child eats in the first 3 years sets the pattern for lifelong dental health.
It's the frequency, not just the food
Teeth decay when acid attacks happen more often than they can recover. Grazing on snacks or sipping sweet drinks across the day keeps teeth under constant acid attack. Three meals and two set snacks, with water in between, lets enamel recover between exposures.
Food choices that protect
Cheese, plain yogurt, nuts (age-appropriate), vegetables and whole fruits support healthy teeth. Whole fruit is fine as a snack; keep dried fruit and juices for mealtimes only, and offer water with snacks. Avoid sugary drinks and sticky sweets that cling to the teeth.
Night is the riskiest time
After the last meal, only water. Milk at bedtime, breastfeeding through the night after teeth arrive, or a bottle in the cot leave sugars on the teeth for hours. Clean the teeth last thing at night and avoid anything but water after that brushing.
