# Top 10 Dental Habits for Primary School Children

Between the ages of about five and eleven, children lose their baby teeth and gain their first permanent ones, take over more of their own tooth care and start making more choices about what they eat and drink. This guide sets out ten dental habits that help to protect children's teeth in these years, from supervised brushing and the right fluoride toothpaste to drinks, lunchboxes, dentist visits, habits and sport. It is written for parents and carers, based on NHS guidance, and is general information, not personal medical advice. Your dentist can advise on your own child.

| Habit | Why it matters | Simple tip |
| --- | --- | --- |
| 1. Supervise brushing twice a day | Children cannot clean well alone yet | Help until about age seven or eight |
| 2. Use the right fluoride toothpaste | Strength depends on age | Check the ppm on the tube |
| 3. Cut down on sugary drinks | A major cause of decay | Water and milk as the norm |
| 4. Plan lunchboxes and snacks | Frequency of sugar matters | Cheese, fruit and vegetables |
| 5. Visit the dentist regularly | Free NHS care for children | Keep the dates |
| 6. Ask about fluoride varnish and sealants | Extra protection for back teeth | Ask at check-ups |
| 7. Handle loose teeth gently | Natural process; avoid forcing | Let teeth fall out on their own |
| 8. Address thumb sucking and dummies | Can affect bite | Gentle encouragement; seek advice |
| 9. Protect teeth during sport | Falls and knocks are common | Ask about a suitable mouthguard |
| 10. Notice early signs of problems | Early help is easier | Look for marks, pain, crowding |

## How this list is ordered

The habits are ordered by how much they protect children's teeth, starting with the daily routine of brushing and fluoride, then drinks and food, professional care, and finally habits, sport and spotting early problems. This is an editorial list based on NHS guidance for parents and carers and not a clinical protocol, and it does not claim to rank habits for every child. Arrangements for NHS dental care differ between the UK nations and can change, so check the NHS website or ask your dental practice. Your child's dentist can adapt advice to their needs, including children with additional needs or medical conditions.

## What changes at primary school age

Children usually lose their first baby teeth from about the age of six, and by around twelve most have a full set of adult teeth apart from the wisdom teeth. The first permanent molars come through at about six, behind the baby teeth, and are often missed by parents because they do not replace a tooth. New permanent teeth have softer enamel at first and are prone to decay, especially in the deep grooves on the chewing surfaces. Children also gain independence, with school meals, birthday parties, sports clubs and pocket money. A few reliable habits in these years protect teeth for life.

## 1. Supervise brushing twice a day

NHS advice is that children should brush twice a day for two minutes, once before bed and once at another time, and that an adult should supervise or help until about the age of seven or eight, when most children have the skill to do it well alone. Young children may rush, miss the back teeth and the gum line, or swallow toothpaste. Stand behind them in front of a mirror, check each area and use a timer or a song. Spit out toothpaste and do not rinse. It ranks first because it prevents most decay. Watch out for skipping the night-time brush, for children eating or drinking after brushing except water and for worn brushes. Replace brushes about every three months.

## 2. Use the right fluoride toothpaste

Fluoride is the key protective ingredient, but the strength should suit the child's age. NHS advice is to use a pea-sized amount of toothpaste with at least 1,000 parts per million of fluoride for children aged three to six, and from the age of seven, the standard family toothpaste with 1,350 to 1,500 ppm is advised. Check the label, because some children's pastes contain less, and ask your dentist if unsure. It matters because too little fluoride gives less protection and too much swallowed can mark developing teeth. Watch out for flavours that tempt children to eat paste, for tubes left within reach, and for rinsing with water after brushing, which removes the fluoride. Supervise to be sure of the amount.

## 3. Cut down on sugary drinks

Sugary and acidic drinks are a major cause of decay in children, particularly when sipped through the day. NHS advice is to make water and milk the main drinks, to keep fruit juice and smoothies to a small glass of about 150ml a day with a meal, and to avoid fizzy and energy drinks. Squash and diet drinks can still be acidic, so dilute and keep them to mealtimes. A water bottle in the school bag makes the healthy choice easy. It ranks third because drinks affect teeth every day. Watch out for sports drinks, flavoured waters, sweet milk drinks and bedtime drinks other than water. Our guide on drinks ranked for teeth explains more.

## 4. Plan lunchboxes and snacks

Frequent sugary snacks keep the mouth acidic and encourage decay. For lunchboxes, choose fruit, vegetable sticks, cheese, plain yoghurt, sandwiches, wholegrain crackers and water, and keep sweets, biscuits, cereal bars and dried fruit for occasional mealtimes. Sticky snacks that cling to the teeth are worse than those that are eaten and cleared quickly. Talk to your child about why, and involve them in choosing. It ranks fourth because it complements brushing. Watch out for hidden sugars in yoghurts, cereal bars and drinks, and for sweets as rewards. Check labels, and aim for tooth-friendly habits that fit your family. Our guide on foods good for teeth gives ideas.

## 5. Visit the dentist regularly

NHS dental care is free for children in the UK, though arrangements differ between nations, and regular check-ups allow the dentist to find decay early, apply preventive treatments and advise on brushing and diet. The dentist will recommend how often your child needs to attend, and some children need to be seen more often. Registering with a practice early and keeping appointments helps children to be at ease. If you cannot find an NHS dentist for your child, contact NHS 111 or your local integrated care board. It ranks fifth because it supports all other habits. Watch out for waiting for pain, for passing on your own fears and for missed appointments. Praise your child for being brave.

## 6. Ask about fluoride varnish and fissure sealants

Fluoride varnish is a concentrated fluoride coating that a dentist or dental nurse paints on the teeth, and NHS guidance recommends that children have it regularly from a young age, usually a couple of times a year. Fissure sealants are thin protective coatings applied to the deep grooves of the back teeth, which are hard to clean and prone to decay, and they are often used on new permanent molars from about six. Neither hurts. Ask your dentist whether your child would benefit and how often. It ranks sixth because these add to home care. Watch out for assuming that varnish or sealants replace brushing, and for sealants that chip, which should be checked at the next visit.

## 7. Handle loose teeth gently

Losing baby teeth is a normal process, and teeth usually loosen gradually and fall out when ready. Children can wiggle a loose tooth gently with a clean finger or tongue, but should not force or pull a tooth that is not ready, which can cause pain, bleeding and damage. A small amount of bleeding is normal and stops quickly with gentle pressure on a clean tissue. Keep brushing around a loose tooth. If a permanent tooth comes through behind a baby tooth, so that there are two rows, or if a baby tooth has not fallen out when the adult tooth is well through, ask the dentist. It ranks seventh because it is mostly nature. Watch out for heavy bleeding, pain, swelling or a tooth lost after a knock.

## 8. Address thumb sucking and dummies gently

Many children suck their thumbs or fingers or use a dummy, and most stop on their own before school age. If it continues beyond the age when the permanent front teeth come through, from about six or seven, it can affect how the teeth and jaws develop and may contribute to an open bite or protruding front teeth. Pressure and shaming usually backfire. Praise, reward charts, distraction and identifying triggers such as tiredness work better, and a dentist or orthodontist can offer advice and, in some cases, habit-breaking approaches. It ranks eighth because it affects only some children. Watch out for sores on the thumb, speech changes and teeth that appear to be moving. Our guides on thumb sucking and dummy habits explain more.

## 9. Protect teeth during sport

Children are active, and falls and knocks to the mouth are common, especially in contact and ball sports, cycling, scootering and playground games. A mouthguard reduces the risk of broken or knocked-out teeth in contact sports, and a dentist can advise about suitable guards for growing mouths, which may need replacing as teeth change. Children with braces need specific advice. Ask the school or club about their policy, and keep a note of what to do if a tooth is knocked out. It ranks ninth because it protects against accidents. Watch out for guards that no longer fit, for wearing a guard only in matches and for ignoring a knock. Seek advice for any tooth that is loose, chipped or discoloured after an injury.

## 10. Notice early signs of problems

Parents can often spot early problems. Look for white, brown or black marks on teeth, swollen or bleeding gums, bad breath that does not clear, a child who avoids certain foods or complains of toothache or sensitivity, teeth that are very crowded or stick out, and a bite that does not meet. Early decay can sometimes be reversed with fluoride, and early orthodontic problems can be monitored. If you are worried, book a dental appointment. Orthodontic assessment is usually considered when most permanent teeth have come through, and your dentist can refer if needed. It ranks last because it relies on all the rest. Watch out for swelling of the face or fever, which need urgent care.

## Making dental care fun and manageable

Children cooperate better when care is positive. Let them choose a brush and a toothpaste flavour that is suitable for their age, use a two-minute timer or app, brush together as a family and share books and games about teeth. Praise effort, use sticker charts, and avoid sweets as rewards. Explain why you do things in simple terms. For children who find brushing hard, because of sensory issues or additional needs, ask the dentist or a health professional for adaptations. Calm and consistency matter more than perfection.

## When to seek dental advice quickly

Contact a dentist promptly if your child has toothache, a swollen face or gum, a tooth that has been knocked out, loosened or discoloured after an injury, bleeding that does not stop, or a mouth sore that lasts more than about two weeks. A knocked-out adult tooth needs urgent attention, and baby teeth should not be put back. Call NHS 111 if you cannot reach a dentist, and seek emergency help for swelling that affects breathing or swallowing or for a head injury. Our guide on dental emergencies explains first-aid steps based on NHS advice.

## School life and teeth

School can be a place of both good and bad habits. Many schools encourage water bottles and healthy snacks, and some run supervised brushing programmes, particularly in areas where decay rates are higher. Talk to your child about drinks and snacks at school, birthday parties and trips, and keep a spare toothbrush for sleepovers. Make sure that the school knows about any dental injury and how to contact you. If your child is bullied or teased about their teeth, braces or breath, listen and tell the school. Dental health is part of overall wellbeing.

## Orthodontic assessment and braces in the primary years

Many parents wonder when to think about braces. Most orthodontic treatment starts in the early teens, once most permanent teeth are through, but some problems benefit from an earlier look, and a dentist can refer for an assessment if they spot crowding, an unusual bite or a habit affecting the teeth. NHS orthodontic treatment depends on clinical need, assessed with a standard index, and waiting lists can be long. An assessment does not mean that treatment will start immediately. Our guides on signs a child may need an assessment and on children's orthodontics explain more.

## Children with additional needs or medical conditions

Some children find tooth brushing or dental visits harder because of sensory sensitivities, autism, ADHD, learning disability, anxiety or physical difficulties, and some have medical conditions or take medicines that affect their teeth. Tell the dental team in advance so that they can plan, for example with a quieter appointment, a visual guide to the visit, a familiar person present or extra time. Adapted brushes and routines can help at home. Community dental services support children who cannot be treated in a general practice. Ask your dentist or health visitor what is available locally.

## A simple weekly check for parents

Once a week, lift your child's lips and look at their teeth in good light. Check for new marks, bleeding gums, loose teeth that are not due, and teeth that look different in colour or shape. Check that their toothbrush is in good shape, that their toothpaste has the right fluoride strength and that the water bottle goes to school. Make a note of any questions for the next dental visit. A minute of attention each week helps you to spot trouble early and keeps your child involved in looking after their own mouth.

## Key takeaways

For primary school children, the key habits are supervised brushing twice a day with the right fluoride toothpaste, water and milk as the main drinks, tooth-friendly lunchboxes, regular dental visits with fluoride varnish and sealants where advised, gentle handling of loose teeth and protection during sport. Seek advice early about marks, pain or habits. This is general information based on NHS guidance, not personal medical advice, so ask your child's dentist.

### Frequently Asked Questions

Until what age should I help my child brush?

NHS advice is to supervise or help until about the age of seven or eight, when most children can brush well alone. Check the back teeth and gum line, and make sure they spit out and do not rinse.

What fluoride toothpaste should my child use?

NHS advice is a pea-sized amount with at least 1,000 ppm fluoride for ages three to six, and from age seven the standard family toothpaste with 1,350 to 1,500 ppm. Check the label and ask your dentist if unsure.

What drinks are best for children's teeth?

Water and milk. Keep fruit juice and smoothies to about 150ml a day with a meal, and avoid fizzy, energy and sports drinks. Diet and squash drinks can still be acidic.

What are fissure sealants?

They are thin protective coatings applied to the deep grooves of the back teeth, which are hard to clean. They are often used on new permanent molars, and the application does not hurt.

Is NHS dental care free for children?

Yes, NHS dental care is free for children in the UK, though arrangements differ between nations. Register with a practice early and keep regular appointments.

Should my child pull out a loose tooth?

It is best to let it fall out when ready, wiggling it gently if they like. Forcing a tooth that is not ready can cause pain and bleeding. Ask a dentist if a baby tooth has not fallen out when the adult tooth is through.

Does thumb sucking affect teeth?

If it continues after the permanent front teeth come through, from about six or seven, it can affect how the teeth and jaws develop. Gentle encouragement works better than pressure, and a dentist can advise.

Does my child need a mouthguard for sport?

A well-fitting mouthguard reduces the risk of broken or knocked-out teeth in contact sports. A dentist can advise on suitable guards for growing mouths, and children with braces need specific advice.
