Overview
Toddlers often knock or chip a baby tooth while learning to walk and play. The tooth may be loose, pushed, chipped or knocked out.
Most injuries are minor, but a check protects the adult tooth forming underneath. Never push a knocked-out baby tooth back in.
What to know
- Common in young, active children
- Have the tooth checked by a dentist
- Never re-implant a knocked-out baby tooth
- Watch for darkening or swelling later
Caring for it
- Stay calm and comfort your child.
- Rinse the mouth gently with water to see the injury.
- Use a cold pack or cool damp cloth on the lip or cheek for swelling.
- If a baby tooth is knocked out, do not try to put it back in.
- Offer soft foods and keep the area clean.
- Give children's pain relief if needed, following the label for their age.
- Book a dental check, even if the injury looks minor.
Call your dentist if…
- Seek urgent care if there is heavy bleeding, a tooth is pushed into the gum, or your child has a deep cut, ongoing pain or swelling.
Common questions
Should I put a knocked-out baby tooth back?
No. Re-implanting a baby tooth can damage the adult tooth growing beneath it.
The tooth has gone grey. Is that bad?
A darkening baby tooth should be checked, though it does not always need treatment.
Does a wobbly baby tooth need treatment?
Often it settles, but your dentist should check how loose it is.
Will this harm the adult tooth?
Usually not, but a check helps spot any rare effect on the developing tooth.
