In short: A baby tooth that falls out naturally is fine. But one lost early to decay or injury needs a dentist — it can let neighbouring teeth drift and crowd the permanent tooth, sometimes needing a small space maintainer. Never push a knocked-out baby tooth back in. Book a check-up to protect the space.
A baby tooth coming out naturally when a permanent tooth is pushing it up is completely normal and no cause for concern. But a baby tooth lost early — because of decay, infection, or a knock or fall — does need a dentist’s attention, because baby teeth do an important job right up until they’re meant to fall out.
The main reason to act is space. Each baby tooth holds a space open for the permanent tooth developing beneath it. If a back baby tooth is lost years too early, the neighbouring teeth can drift into the gap, leaving too little room when the permanent tooth is ready to come through. That can lead to crowding, crooked teeth, and the need for braces later. In these cases a dentist may fit a simple space maintainer — a small appliance that holds the gap open until the permanent tooth arrives.
What to do:
- If it’s due to a knock or injury, see a dentist soon to check for damage to the gum, the developing permanent tooth, or nearby teeth. (Note: unlike an adult tooth, a knocked-out baby tooth should not be pushed back into the socket.)
- If it fell out due to decay or infection, book a check-up — other teeth may need attention too, and the dentist will assess whether a space maintainer is needed.
- Keep the area clean and give soft foods for a day or two if the gum is tender.
Losing a baby tooth early isn’t an emergency, but it’s worth a prompt visit. Book a children’s dental check-up so we can protect the space and your child’s future smile.
