Tooth pain in children

Overview

Tooth pain in children is discomfort or aching in or around a child's tooth. It can range from a mild twinge to severe, constant pain and is often a sign that something needs attention from a dentist.

Yes, tooth pain is very common in children. Many children experience it at some point, especially during teething or if they develop cavities.

It can affect children of all ages, from babies who are teething to older children who have permanent teeth. It is especially common in children who have not yet learned good brushing habits or who eat a lot of sugary foods.

Symptoms

Common symptoms

• Constant or sharp pain in a tooth or jaw
• Pain that gets worse when eating or drinking hot, cold, or sweet things
• Tenderness or swelling in the gums near a tooth
• Bad breath or a bad taste in the mouth

Symptoms in children

• Fussiness or crying, especially during feeding or at bedtime
• Pulling at the ear or touching the face on one side
• Refusing food or drink
• Chewing on one side of the mouth

Causes

Main causes

• Tooth decay (cavities) – acid from bacteria damages the tooth
• Teething – when new teeth push through the gums in babies
• Injury – a fall or accident that chips or knocks a tooth
• Infection or abscess – a pocket of pus inside the tooth or gum

Risk factors

• Poor brushing and flossing habits
• Frequent snacking on sugary or sticky foods
• Not getting enough fluoride in water or toothpaste
• Having deep grooves in teeth (which trap food)
• Wearing braces or other dental appliances

When to see a doctor

See a doctor urgently if:

• If there is swelling in the face or neck that is getting worse
• If your child has a fever along with tooth pain
• If the pain is severe and does not get better with simple pain relief (like children's paracetamol or ibuprofen, as directed by a pharmacist)

Book a routine appointment if:

• If the pain lasts more than 1–2 days
• If you notice a spot or hole in your child's tooth
• For a regular dental checkup every 6–12 months

Diagnosis

A dentist will ask about your child's symptoms, look inside the mouth, and gently tap the teeth to find the painful one. They may also take an X-ray to see hidden cavities or infections.

Tests that may be done

• Visual examination of the teeth and gums
• Dental X-rays to check for decay between teeth or below the gum line

What to expect at your appointment

The dentist will explain what is causing the pain and suggest the best treatment. They will talk to you and your child in a calm, friendly way. Most visits are quick and not painful.

Treatment

Treatment depends on the cause of the pain. The goal is to relieve pain, treat any infection, and save the tooth if possible.

Self-care at home

• Give your child a soft toothbrush and brush gently around the sore area
• Rinse the mouth with warm salty water (if your child can spit it out)
• Offer cold drinks or a cold compress on the cheek to reduce swelling
• Use over-the-counter children's pain medicine as directed by a pharmacist or doctor – never give aspirin to children

Medical treatments

A dentist may clean out decay and place a filling, or apply a fluoride varnish to a sensitive area. For an infection, they may need to drain pus and prescribe antibiotics. In some cases, a baby tooth may need to be removed to protect the permanent tooth underneath.

When is surgery considered?

If a tooth is badly damaged or infected, a dentist may recommend extraction (pulling the tooth). This is usually done with local anaesthetic to numb the area. An infected tooth may need a root canal treatment if the permanent tooth is involved.

Living with this condition

With proper dental care, most children recover quickly from tooth pain. Encourage your child to brush twice a day with fluoride toothpaste and floss once a day. Keep up with regular dental visits.

Lifestyle tips

• Help your child brush their teeth until they are about 8 years old
• Limit sugary snacks and drinks, especially between meals
• Provide a balanced diet with fruits, vegetables, and calcium-rich foods

Diet and exercise

A healthy diet helps keep teeth strong. Avoid sticky sweets like caramel and lollipops. Drinking water after meals can help wash away food bits. Exercise and play are fine – just encourage a mouthguard during contact sports to prevent injuries.

Mental health and emotional wellbeing

Tooth pain can make children feel irritable, upset, or anxious, especially if they fear the dentist. Reassure them that dentists are there to help and that pain relief will come. Talk calmly about what to expect at the visit.

Prevention

Most tooth pain in children can be prevented with good oral hygiene and healthy habits. Brushing, flossing, regular dental checkups, and limiting sugary foods are key.

Screening programmes

Regular dental checkups starting from when the first tooth appears (usually around 6 months) help catch problems early.

Complications

If left untreated

• Spread of infection to the jaw, face, or bloodstream (serious)
• Damage to the permanent tooth growing under a baby tooth
• Abscess (pus pocket) that may require more intensive treatment

Long-term outlook

With prompt care, almost all tooth pain in children can be successfully treated. Simple cavities can be filled, and infections can be cleared. Healthy habits help protect your child's smile for years to come.
