Back to School Smiles

Oral Health Tips

As the new school year begins, families across Ireland are stocking up on uniforms, copies, and lunchbox essentials. But one item often overlooked can have a huge impact on your child’s success in school – their oral health. Tooth decay is still the most common chronic childhood disease in Ireland. Around 1 in 3 children under 5 years old experience decay, and many 12-year-olds already have cavities in their back teeth. Poor oral health can lead to pain, missed school days, difficulty concentrating, and even lower self-confidence. Starting the term with a healthy smile is just as important as having the right schoolbag.

Here are expert-backed tips to help your child stay cavity-free this year!

Book a Dental Check-Up

If it’s been a while since your child’s last visit, get an appointment in before school schedules get hectic. Regular check-ups mean problems can be spotted early and advice given for keeping teeth healthy all year.

Replace their Toothbrush

Children’s toothbrushes should be changed every 3 months, or sooner if the bristles are worn. A child-sized brush makes it easier to reach all teeth comfortably.

Supervise Brushing

Children should brush twice a day for 2 minutes using a smear of fluoride toothpaste. Turn brushing into a fun activity. Try brushing together, using a timer, or even a favourite song to keep them engaged.

• Use a soft-bristled brush with a small head.
• Angle the brush at 45° to the gum line.
• Gently clean all surfaces, including the inside of the front teeth.

Pack a Tooth-Friendly Lunchbox

Most Irish schools now follow healthy eating policies. Aim for:

• Whole grains, fruit, veg, nuts/legumes, lean protein, and dairy in moderation.
• Drinks: water or milk instead of sugary juices or fizzy drinks.

Protect with a Sports Mouthguard

If your child plays rugby, GAA, football, or any contact sport, a properly fitted mouthguard is essential. Ask your dentist or coach about the best options – it could prevent a painful (and costly) dental injury.

Limit Snacking

Frequent grazing can expose teeth to constant acid attacks, increasing the risk of decay. Encourage snacks at mealtimes where possible, and swap sugary treats for healthier alternatives.

Good oral health doesn’t just mean fewer trips to the dentist, it supports your child’s confidence, focus, and wellbeing. As you prepare for the year ahead, make oral hygiene part of the back-to-school routine and give your child the best start with a happy, healthy smile.
