Diet Advice for Children’s Teeth 🥕

Healthy eating habits help protect your child’s smile for life.
A balanced diet is one of the most important ways to prevent tooth decay in children. What your child eats — and how often they eat it — has a big impact on their oral health. At Hazlemere Dental Practice, we help families make simple, realistic changes that keep children’s teeth strong and healthy.

1. Keep Sugary Foods to Mealtimes Only

Frequent snacking is one of the biggest causes of tooth decay. Every time your child eats something sugary, their teeth are exposed to acids for up to 30 minutes.

Better habits include:

• Offer sweets, biscuits or chocolate only with meals
• Avoid grazing throughout the day
• Choose tooth-friendly snacks between meals

2. Choose Tooth-Friendly Snacks

Great options include:

• Cheese cubes
• Fresh fruit (not dried fruit)
• Breadsticks
• Plain yoghurt
• Veggie sticks
• Rice cakes

Avoid sticky snacks like raisins, fruit bars and dried fruit — they cling to teeth and cause decay.

3. Water and Milk Are the Best Drinks

Sugary drinks are one of the biggest contributors to decay.

Best choices:

• Water
• Milk

Try to avoid:

• Squash
• Fizzy drinks
• Fruit juice
• Milkshakes
• Flavoured waters

If your child does have a sugary drink, keep it to mealtimes and use a straw to reduce contact with teeth.

4. Avoid Sugary Drinks at Bedtime

Even diluted squash or juice can cause rapid decay when teeth aren’t brushed afterwards. Only water should be given after brushing at night.

5. Be Careful With “Healthy” Sugars

Some foods seem healthy but can be harmful to teeth:

• Smoothies
• Fruit juice
• Honey
• Dried fruit
• Flavoured yoghurts

These contain natural sugars that still cause decay.

6. Encourage a Balanced Diet

A healthy diet supports strong teeth and gums. Aim for:

• Plenty of fruit and vegetables
• Whole grains
• Lean proteins
• Dairy or calcium-rich alternatives

7. Combine Good Diet With Good Brushing

Diet and brushing work together. Children should brush twice daily with fluoride toothpaste.

• Keep sugary foods to mealtimes
• Choose tooth-friendly snacks
• Water and milk are best
• Avoid sugary drinks at bedtime
• Watch out for hidden sugars
• Support with good brushing habits

Small changes make a big difference to your child’s long-term oral health.
