If your child has a toothache, rinse their mouth with warm water, gently floss around the sore tooth to remove trapped food, give a child-safe pain reliever at the right dose, and call the dentist for an appointment. Most children’s toothaches come from cavities, food stuck between teeth, or new teeth coming in. Swelling, fever, or a knocked-out adult tooth needs same-day care. A gentle family dentist in Bolton can find the cause quickly.
Many toothaches can be prevented with regular hygiene services, where cavities are caught while they’re still small.
Children who feel anxious about the dentist can be helped with a calm approach and, when appropriate, sedation options.
If a baby tooth is badly decayed or infected, a gentle extraction may be the kindest fix. To get seen quickly, request an appointment online. Same-day visits are available when possible.

What causes toothache in children?
| Cause | Clues |
|---|---|
| Cavity | Pain with sweets or cold, dark spot or hole |
| Trapped food | Pain after eating, eases after flossing |
| New adult molar coming in | Sore gum at the back, around age 6 or 12 |
| Loose baby tooth | Wobbly tooth, tender gum |
| Injury | Recent fall or knock, chipped or darkened tooth |
| Abscess | Swelling, pimple on gum, fever, bad taste |
| Grinding | Morning soreness, worn teeth |
| Sinus or ear infection | Ache in upper back teeth with cold symptoms |

How can you ease your child’s tooth pain at home?
- Warm water rinse: for children old enough to swish and spit.
- Gentle flossing: food caught between teeth is a common cause.
- Pain relief: children’s acetaminophen or ibuprofen, dosed by age and weight. Check with a pharmacist if unsure.
- Cold compress: wrapped ice on the cheek for 10 to 15 minutes.
- Soft, cool foods: yoghurt, smoothies, and soup that’s not too hot.
- Extra pillow at night: raising the head can ease throbbing.
Avoid these
- Aspirin for children and teens, due to the risk of Reye’s syndrome
- Putting any pill directly on the gum
- Numbing gels with benzocaine for young children, as Health Canada advises
- Applying heat to a swollen face
- Waiting to see if it goes away
How can you tell where the pain is coming from?
Young children often struggle to describe tooth pain. They may point to their ear, rub their cheek, or refuse to eat. A few gentle questions and a quick look can help.
- Ask them to point with 1 finger to the sore spot.
- Check whether it hurts with cold, sweet, or biting.
- Look for dark spots, holes, chipped edges, or a swollen gum.
- Gently press on the gum near the tooth to see if it’s tender.
- Note whether the pain comes and goes or is constant.
Share what you notice with the dental team. It helps them find the cause faster.
What treatments might your child need?
- Filling: for a small or medium cavity, often tooth-coloured.
- Pulpotomy: a “baby root canal” that removes the inflamed part of the nerve in a baby tooth.
- Stainless steel or tooth-coloured crown: protects a baby molar with a large cavity.
- Extraction: for a badly infected or broken baby tooth.
- Space maintainer: holds space for the adult tooth if a back baby tooth is removed early.
- Sealants and fluoride: to prevent new cavities.
How does diet affect toothache risk?
It’s how often children have sugar that matters most. Every sip of juice or nibble of a sweet snack feeds cavity-causing bacteria for about 20 to 30 minutes. Grazing on snacks and sipping sweet drinks all day keeps teeth under constant attack.
Try keeping treats to mealtimes, offering water and milk as main drinks, and choosing tooth-friendly snacks like cheese, vegetables, and plain yoghurt. Sticky snacks such as gummies and fruit leather cling to teeth, so brush or rinse after them.
When is a child’s toothache an emergency?
- Swelling in the face, cheek, or jaw
- Fever with tooth pain
- A knocked-out adult tooth
- A broken tooth with pink or red showing in the centre
- Pain after a fall or blow to the face
- Difficulty swallowing or breathing (go to the emergency department)
What should you do if an adult tooth is knocked out?
- Find the tooth and pick it up by the crown, not the root.
- If dirty, rinse briefly in milk or saline. Don’t scrub.
- Try to place it back in the socket and have your child bite on gauze.
- If you can’t, store it in milk or inside the cheek (for older children).
- See a dentist within 30 to 60 minutes.
Don’t put a knocked-out baby tooth back in. It can damage the adult tooth underneath. Call the dentist for advice.
What happens at the dental visit?
- A gentle chat: the team talks to your child in simple, calm words.
- Looking: the dentist checks the tooth, gums, and bite.
- X-ray: a small image may be needed to see inside the tooth.
- Treatment: a filling, a baby tooth nerve treatment, or an extraction, depending on the cause.
- Prevention plan: tips on brushing, diet, and sealants.
Do baby teeth with cavities need treatment?
Yes. Untreated cavities in baby teeth can cause pain, infection, and trouble eating and sleeping. Infection can also affect the adult tooth developing underneath. Back baby teeth often stay until age 10 to 12, so they need to stay healthy for years.
How can you prevent toothaches in children?
- Brush twice a day with fluoride toothpaste: a rice-grain smear under 3, pea-sized from 3 to 6.
- Help with brushing until about age 8.
- Floss once teeth touch.
- Limit sugary snacks and drinks to mealtimes.
- Offer water between meals.
- Ask about sealants on back adult molars.
- Use an athletic sports guard for hockey, soccer, and other contact sports.
- Keep check-ups every 6 months.
How can you help a nervous child?
- Stay calm and positive yourself.
- Use simple words like “the dentist will count and clean your teeth”.
- Avoid words like “hurt”, “needle”, or “pull”.
- Bring a comfort toy.
- Praise them afterwards for being brave.
Common myths about children’s toothaches
“Baby teeth fall out, so cavities don’t matter.”
Infected baby teeth can cause pain and harm adult teeth.
“Toothache in kids is usually just teething.”
Teething affects babies and toddlers. In older children, pain usually has another cause.
“If the pain stops, the problem is gone.”
Pain can fade while infection grows. A check-up is still needed.
“Kids can’t have sedation at the dentist.”
Some children benefit from safe, appropriate sedation options.
Real family examples
The popcorn kernel. An 8-year-old had sudden gum pain after a movie night. Flossing at home dislodged a kernel, and the pain eased within hours.
The hidden cavity. A 6-year-old complained when eating candy. An X-ray showed decay between 2 baby molars, fixed with small fillings.
The hockey puck. A 12-year-old knocked out a front tooth at practice. His coach put it in milk, and it was replanted within the hour. He now wears a custom sports guard.
