Child's toothache: what parents can do, and when to see a dentist

A child with toothache is upset and so are you. Children often cannot say exactly where it hurts, so look for the signs and act early.

What can cause it?

• A cavity in a baby tooth. This is the most common cause. See what causes tooth decay.
• Food stuck between teeth.
• A new tooth coming through, which can make the gum sore.
• A gum infection or an abscess, sometimes with a swollen cheek.
• An injury to a tooth.

What are the signs?

A child may refuse food, chew on one side, cry when drinking something cold or sweet, hold the cheek, wake at night, or have a swollen gum or face.

What can you do at home?

1. Look in the mouth for stuck food or a visible hole, and gently clear any food with floss.
2. Rinse with warm water. Older children can use warm water with a little salt, and they must spit it out.
3. A cold pack, wrapped in cloth, on the outside of the cheek can ease swelling.
4. Offer soft, lukewarm food and avoid sweets.

What should you not give?

• Do not give aspirin to a child. It is not safe for children.
• Do not put a tablet, clove oil or any gel on the gum unless a doctor or dentist has said to.
• Ask a doctor or pharmacist about a children’s pain medicine and the dose for your child’s weight and age. Follow the pack.

Do baby teeth really need treatment?

Yes. Baby teeth help a child eat and speak, and they hold the space for the adult teeth. An infected baby tooth can cause pain, swelling and harm the adult tooth underneath. A baby tooth with a cavity should be seen to, even if it will fall out later.

When to go the same day

Go the same day if there is swelling of the face, eye or neck, a fever, trouble swallowing or breathing, or if your child cannot eat or drink. If there was a blow to the head, go to a hospital. Read dental emergency: when to go today.

Preventing the next one

Keep sweets to mealtimes, give water between meals, and brush twice a day with a small amount of fluoride toothpaste. Help your child brush until they can do it well. See food and drinks that harm your teeth.
