Dental Checks For Young Children

Overview

A dental check for a young child is a short, gentle appointment where a dentist looks at your child's teeth, gums and mouth to make sure everything is healthy and growing as it should. It is not only about finding holes in teeth (cavities). It is also about spotting small problems early, giving you practical advice on brushing and drinks, and helping your child get used to the dentist so visits feel normal rather than scary.

Yes. Dental check-ups are one of the most common routine appointments in childhood, and almost every child has them. Needing a check is completely normal and nothing to worry about.

Symptoms

Common symptoms

• This is a routine check, not an illness, so there may be no symptoms at all — that is the point of going regularly.
• White or brown spots on the teeth, especially near the gum line
• Toothache or a tooth that feels tender when eating or drinking something cold, hot or sweet
• Gums that bleed a little when brushing
• Bad breath that does not go away after brushing

Symptoms in children

• Crying or waking at night with tooth pain
• Chewing on one side, or refusing crunchy foods
• Not wanting to eat or drink cold things
• A visible hole or dark patch in a tooth
• Swelling of the gum near a tooth
• Being upset or anxious about having their mouth looked at

Causes

Main causes

• Tooth decay happens when plaque (a sticky film of bacteria on the teeth) feeds on sugar from food and drinks and makes acid. Over time the acid softens the outer layer of the tooth and a hole can form.
• Not brushing well, or not brushing often enough, lets plaque build up.
• Sugary foods and drinks — especially between meals and in a bottle at bedtime — give the acid more chances to attack the teeth.
• Not getting enough fluoride (a mineral that makes the outer tooth surface stronger) raises the risk of decay.
• Missing regular dental checks means small problems are found later, when they are harder to fix.

Risk factors

• Having had decay in a baby tooth before
• Frequent sugary snacks or drinks through the day
• Going to sleep with a bottle of milk or sweet drink
• A close family member with a lot of tooth decay
• Special health needs, a dry mouth, or a condition that makes brushing harder
• Weak enamel (the hard outer coating of the tooth) from birth
• Difficulty getting to a dentist or finding an NHS dentist

When to see a doctor

See a doctor urgently if:

• Facial swelling, or swelling around the eye
• A knocked-out or badly broken permanent tooth
• Severe pain that keeps your child awake or stops them eating
• Bleeding that will not stop
• A high temperature together with tooth pain or swelling

Book a routine appointment if:

• When your child's first tooth appears, or by their first birthday
• Then every 6 to 12 months, or as often as your dentist advises
• Before your child starts school, so any problems can be sorted early
• If you notice white or brown spots, a hole, or bleeding gums
• If your child grinds their teeth, sucks their thumb or uses a dummy and you want advice
• If you need help with brushing technique, toothpaste choice or fussy eating

Diagnosis

The dentist will look inside your child's mouth using a small mirror and a bright light. They count the teeth, check the gums and soft tissues, and look for early signs of decay. They may ask you about brushing, drinks, snacking and whether there is any pain. Your child can sit on your lap for the check if that helps them feel safe. Dentists often use a 'tell, show, do' approach — explaining and demonstrating before they look.

Tests that may be done

• A visual examination of the teeth and gums
• An X-ray of the teeth, but only if your child is old enough and the dentist thinks one is needed
• A fluoride varnish application, which may be offered as part of the visit
• A discussion about diet, brushing and habits

What to expect at your appointment

The first visit is often very short — sometimes just a look and a chat. Later checks usually take about 10 to 20 minutes. You will normally be told straight away whether everything looks fine or whether anything needs watching or treating.

Treatment

For most children, no treatment is needed at all. The check is about keeping teeth healthy: advice on brushing, drinks and snacks, plus a protective fluoride varnish if it is suitable. If early decay is found, it can often be stopped or reversed with varnish and better brushing. Bigger holes may need a small filling, and badly damaged baby teeth are sometimes removed.

Self-care at home

• Brush your child's teeth twice a day, including just before bed, and help or supervise until they are about 7 or 8 years old.
• Use a fluoride toothpaste, and ask your dentist, health visitor or pharmacist what strength and how much is right for your child's age.
• Brush for about two minutes, gently covering every tooth and the gum line.
• Teach your child to spit out after brushing rather than rinse with water — rinsing washes away the protective fluoride.
• Keep sugary foods and drinks to mealtimes rather than spreading them through the day.
• Offer water or plain milk between meals. Water is the best drink for teeth.
• Do not put sugary drinks or juice in a bottle, and do not let your child go to sleep with a bottle.
• Take your child for a check as often as the dentist recommends, even if their teeth look fine.

Medical treatments

Treatment is decided by the dentist and depends on what they find. Options include fluoride varnish, which is painted on to strengthen the tooth surface; sealants, a protective coating on the chewing surfaces of back teeth; and small fillings for holes. If a baby tooth is badly decayed or infected, the dentist may recommend removing it. Some children are referred to a children's dental service, and for very young or very anxious children treatment can sometimes be done with sedation or a general anaesthetic. Your dentist will explain the choices and answer your questions.

When is surgery considered?

Removing a tooth may be suggested if a baby tooth is so decayed or infected that it cannot be repaired, or if it is causing pain or damaging the adult tooth underneath. This is usually done with a local anaesthetic to numb the area, and for some children it is done in a specialist clinic.

Living with this condition

Looking after young teeth is mostly about routine: brushing twice a day, keeping sugary treats to mealtimes, and going for regular checks. Making brushing part of the same daily pattern — after breakfast and before bed — helps it become automatic. A timer, a favourite song or a sticker chart can help younger children cooperate.

Lifestyle tips

• Make brushing a normal part of the day, not a battle — brush alongside your child.
• Keep sugary snacks and drinks as occasional mealtime treats, not everyday habits.
• Choose sugar-free medicines when your child needs them, and ask your pharmacist for advice.
• Do not share spoons, cups or toothbrushes — the bacteria that cause decay can pass between people.
• If your child uses a dummy or sucks their thumb, ask your dentist for advice on when and how to stop.
• Book the next check before you leave the surgery so it is not forgotten.

Diet and exercise

For teeth, the key is how often sugar hits them rather than only how much. Snacks like cheese, plain yoghurt, fruit and vegetables are kinder to teeth than biscuits, sweets and dried fruit. Water and plain milk are the best everyday drinks. Being active and eating well overall supports healthy growth, and a balanced diet helps build strong teeth from the start.

Mental health and emotional wellbeing

Dental visits can make some children anxious, especially after pain or a previous treatment. This is common and can be gently worked through — tell the dentist how your child feels, and ask for a short 'meet and greet' visit first if that would help. Toothache can also affect sleep, mood and concentration at school, so sorting problems early supports your child's wellbeing as well as their teeth.

Prevention

Most tooth decay in young children can be prevented. Brushing twice a day with fluoride toothpaste, limiting sugary foods and drinks, and going for regular dental checks greatly reduce the chance of problems. Starting these habits early makes them stick.

Vaccines

There is no vaccine for tooth decay. Routine childhood vaccinations are still important for your child's general health, so keep them up to date.

Screening programmes

Regular dental checks are the screening for children's teeth. They let the dentist spot early changes before a hole forms, and offer protective treatments such as fluoride varnish where suitable.

Complications

If left untreated

• Toothache and pain that disturbs sleep, eating and school
• Infection and abscesses in the gum or jaw
• Early loss of baby teeth, which can affect how adult teeth come through and how your child speaks and eats
• A need for more involved treatment, sometimes under sedation or general anaesthetic
• Dental anxiety that carries into adulthood
• Missed school days for your child and time off work for you

Long-term outlook

The outlook is very good. Children's teeth respond well to simple prevention, and early changes can often be stopped before a hole forms. Regular checks plus good brushing and sensible drinks give most children a healthy set of teeth — and habits that last a lifetime.
