Losing a tooth is a normal part of childhood, and most of the time it’s nothing to worry about. Kids typically start losing baby teeth around age 6 and continue through age 12. When it happens naturally, you just need to manage a little bleeding and keep the area clean. But if a permanent tooth gets knocked out from a fall or injury, the situation is more urgent and requires fast action.
When a Baby Tooth Falls Out Naturally
Baby teeth usually loosen on their own and come out with minimal fuss. Once the tooth is out, have your child bite down gently on a piece of clean gauze or a soft cloth to stop the bleeding. The bleeding is typically light and should slow within a few minutes. If your child’s gums look swollen or sore, a cold compress on the outside of the cheek can help with both swelling and discomfort.
Don’t try to put a baby tooth back in. Replanting a baby tooth can damage the permanent tooth developing underneath the gum. Once it’s out, it’s out for good. Rinse it off, tuck it under the pillow for the tooth fairy if your child is into that, and move on.
Cleaning the Empty Socket
After the tooth comes out, have your child rinse gently with warm saltwater. It won’t taste great, but it helps clean the empty socket and reduce the chance of irritation. Use about half a teaspoon of salt in a small glass of warm water.
Your child should keep brushing twice a day with a soft-bristled toothbrush, being a little extra gentle around the gap. Flossing once a day should continue as usual. The gum tissue over the socket heals quickly in kids, and normal brushing habits help keep the surrounding teeth and gums healthy while the permanent tooth makes its way in.
Managing Pain After Losing a Tooth
Most of the time, losing a baby tooth naturally causes only mild soreness. A cold compress held against the cheek for 10 to 15 minutes is often enough. If your child needs more relief, children’s ibuprofen and acetaminophen are both effective options for dental pain. Research on pediatric dental pain found that combining the two (alternating doses, not taking them at the same time) appears to be the most effective approach for kids 12 and under, working better than either one alone.
Stick to soft foods for the rest of the day. Yogurt, applesauce, mashed potatoes, and smoothies are all easy choices that won’t irritate the socket. Avoid anything crunchy, spicy, or very hot until the area feels comfortable again.
If a Permanent Tooth Gets Knocked Out
This is a completely different situation. When a child loses a permanent tooth from an injury, like a fall, a collision during sports, or an accident, you need to act fast. Teeth treated within 30 minutes to one hour have the best chance of being successfully replanted. Every minute counts because the soft tissue fibers connecting the tooth root to the jawbone dry out quickly in open air, and once those fibers die, the tooth is much harder to save.
Here’s what to do immediately:
- Find the tooth. Pick it up by the white crown (the part you normally see). Never touch the root.
- Rinse gently if dirty. Hold it under clean water for no more than 10 seconds. Don’t scrub it, don’t use soap, and don’t wrap it in tissue.
- Try to put it back in. If you can, gently push the tooth back into the socket and have your child hold it in place by biting down on a cloth. This gives the tooth the best environment for survival.
- If you can’t replant it, store it properly. Drop the tooth into a container of cold milk. Milk is widely recommended because it keeps the root’s living cells viable for a meaningful period of time. If you don’t have milk, saline solution works for up to about two hours. Saliva (having your child spit into a cup and placing the tooth in it) is better than nothing. Do not store the tooth in plain water, which damages the root cells.
- Get to a dentist or emergency room immediately. Call ahead so they can prepare.
The ideal storage solution is a product called Hank’s Balanced Salt Solution, which is what the American Association of Endodontists recommends. Some school nurses and sports facilities keep it in their first aid kits. But milk is nearly as effective and far easier to find in most situations, which is why it’s the standard recommendation for parents.
How to Tell if It’s a Baby Tooth or Permanent Tooth
This distinction matters because the response is so different. Baby teeth are smaller, whiter, and have shorter roots (or almost no visible root if the tooth was already loose). Permanent teeth are larger, slightly more yellow, and have a longer, more defined root. If the tooth was already wiggly and your child is in the typical age range for losing teeth, it’s almost certainly a baby tooth. If a solid tooth got knocked out by an impact, especially in a child over 7 or 8, there’s a real chance it’s a permanent tooth. When in doubt, save the tooth in milk and get to a dentist quickly.
What to Expect as New Teeth Come In
After a baby tooth falls out, the permanent tooth usually starts appearing within a few weeks to a few months. Sometimes you can already see the edge of the new tooth poking through before the baby tooth is fully gone. Other times, the gap sits empty for a while. Both are normal. The new tooth may look large compared to the remaining baby teeth, and it may come in slightly crooked. This is common and often corrects itself as the jaw grows and the rest of the permanent teeth fill in.
If no permanent tooth appears after six months, or if you notice the gum tissue looking red, swollen, or painful in the weeks after the tooth falls out, a dental visit can rule out any issues with the incoming tooth’s positioning.
