When your child has a dental emergency, your instincts kick in fast. You want to stop the pain, fix the problem, and make them feel safe, all at the same time. That instinct is good. But in the panic of the moment, even the most attentive parents sometimes reach for "fixes" that feel right and actually make things worse.

Some of the most common reactions are things nearly every parent would try:

• Rinsing off a knocked-out tooth.
• Putting something on the gum to numb the pain.
• Heading to the nearest emergency room.

These all sound perfectly reasonable in the moment. But depending on the situation, each one could permanently damage a tooth, cause additional injury, or send you somewhere that can't actually help.

The good news is that knowing what not to do is just as valuable as knowing what to do. This post walks you through seven of the most common mistakes parents make during a child's dental emergency, along with simple, clear guidance on what to do instead. Keep it bookmarked. Hopefully you'll never need it, but if you do, you'll be glad it's there.

Mistake #1: Putting Aspirin Directly on the Tooth or Gum

It makes sense on the surface. Your child is in pain, aspirin relieves pain, so why not apply it right where it hurts? Unfortunately, this is one of the most damaging things you can do in the moment.

Aspirin is an acid. When it sits directly on soft gum tissue, it causes an aspirin-induced chemical burn. The tissue turns white, becomes raw and painful, and can take days or even weeks to heal on its own. You've added a second injury on top of the original problem.

There's also a separate concern worth knowing: aspirin is not recommended for children at all due to the risk of Reye syndrome, a rare but serious condition that can affect the liver and brain.

Do this instead: Give your child an age-appropriate dose of ibuprofen or acetaminophen by mouth, following the label's dosing instructions. These are safe and effective, and they won't cause any additional damage. Then call your dentist.

Mistake #2: Trying to Reimplant a Knocked-Out Baby Tooth

If your toddler or young child knocks out a tooth and you find it on the ground, the instinct is to put it back. That's exactly the right instinct for a permanent tooth. For a baby tooth, though, it's the wrong move.

Baby teeth sit directly above the developing permanent teeth underneath. Trying to push a knocked-out primary tooth back into the socket risks your child swallowing or inhaling it, and can damage the permanent tooth bud forming just below the gumline. The roots of baby teeth are shorter and more fragile, making proper reimplantation very difficult even for a dentist.

The good news is that losing a baby tooth early, while not ideal, is manageable. Your dentist may recommend a space maintainer to hold the gap until the permanent tooth comes in on its own.

Do this instead: Don't try to reimplant it. Keep the tooth if you can find it, bring it to the appointment, and call your dentist as soon as possible so they can assess the socket and the surrounding teeth.

Mistake #3: Storing a Knocked-Out Permanent Tooth in Water

If your child knocks out a permanent tooth, getting to a dentist quickly is critical. But how you store that tooth in the meantime matters just as much as how fast you move.

Water seems like a safe, neutral option. It's actually one of the worst things you can store a tooth in. Tap water has a different salt concentration than the cells on the root surface. When those root cells sit in plain water, they absorb it, swell, and burst. This destroys the periodontal ligament cells that are essential for the tooth to reattach successfully. Within 20 to 30 minutes in water, the chances of saving the tooth drop significantly.

Do this instead: Place the tooth in a small container of cold whole milk. Milk's composition is close enough to the fluid around those root cells that it keeps them alive. If milk isn't available, have your child hold the tooth gently inside their cheek (as long as they're old enough not to swallow it), or use a tooth preservation kit like Save-A-Tooth if you have one. Get to a dentist as quickly as possible, ideally within the hour.

Mistake #4: Rinsing or Scrubbing a Knocked-Out Tooth Under the Tap

You find a knocked-out tooth on the ground and it's dirty. Of course you want to clean it before putting it back. This is one of those situations where the instinct is completely understandable and also genuinely harmful.

Those same periodontal ligament cells we described above are destroyed just as easily by rinsing or scrubbing. Running the tooth under tap water washes them away. Scrubbing the root removes them entirely. Either way, you've significantly reduced the chances of saving the tooth.

Do this instead: Handle the tooth only by the crown, the white part you can see in the mouth. If it's visibly dirty, give it one brief, gentle rinse with milk or saline. Do not scrub, wipe, or soak it. Then store it in milk and get to the dentist as quickly as you can.

Mistake #5: Ignoring a Chipped or Cracked Tooth Because There's No Pain

When a child chips a tooth and isn't crying, it's easy to file it under "minor" and keep an eye on it. Pain, after all, usually means something is wrong. No pain seems to mean things are fine.

With dental injuries, though, the absence of pain isn't always a green light. A chip or crack can expose the inner layers of the tooth to bacteria, even when the nerve hasn't been affected yet.

Over time, that exposure can lead to infection, sensitivity, or more significant damage that requires a more involved treatment to address. Some cracks are also not visible to the naked eye and may be affecting more of the tooth than they appear to.

Getting a chipped or cracked tooth evaluated promptly gives your dentist the chance to catch issues early, when they're far easier to treat.

Do this instead: Call your dentist within 24 hours of any chip or crack, even if your child seems completely unbothered. Save any broken pieces if you can find them. Avoid hard or crunchy foods until the tooth has been examined.

Mistake #6: Reaching for Orajel or Benzocaine Products to Ease the Pain

When a child is in pain and it's late at night, the tube of Orajel in the medicine cabinet looks like a lifesaver. It's sold right next to the children's ibuprofen, so it feels like a perfectly safe option. 

But the FDA has issued a clear warning against using benzocaine products, including Orajel and similar numbing gels, on children for tooth or gum pain.

The concern is a condition called methemoglobinemia, in which the blood loses its ability to carry oxygen effectively. It can develop quickly, and in young children in particular, it can be serious. 

Symptoms include pale or grayish skin, shortness of breath, and fatigue. It's rare, but the risk is real enough that the FDA advises against these products for children entirely.

Do this instead: Children's ibuprofen or acetaminophen, dosed by weight and age, is your best option for managing dental pain safely at home. A cold compress on the outside of the cheek can also help with swelling and discomfort. Reach out to your dentist, even after hours, because most pediatric dental practices have a protocol for urgent calls.

Mistake #7: Automatically Going to the ER or Assuming You Shouldn't

When something happens to your child's teeth, and it's 9 p.m. on a Sunday, the emergency room feels like the obvious answer. Other times, parents assume a dental problem isn't serious enough to warrant a trip to the ER and wait it out until Monday morning. Both assumptions can lead you in the wrong direction.

The truth is that emergency rooms and dental offices handle different things well. Most ERs are not equipped to reimplant teeth, repair chips, or treat dental injuries the way a dentist can. If your child knocks out a permanent tooth and you spend two hours in an ER waiting room, that tooth is almost certainly not getting saved. For most dental injuries, your pediatric dentist is the right first call, even after hours, because most practices have an emergency line for situations like these.

On the other hand, there are real dental emergencies that belong in the ER. If your child has uncontrolled bleeding that won't stop after 15 to 20 minutes of firm pressure, swelling that is spreading to the face, neck, or floor of the mouth, difficulty breathing or swallowing, or a possible jaw fracture, go to the ER right away. A dental infection that has spread beyond the mouth can quickly become a medical emergency.

Do this instead: When in doubt, call your pediatric dentist first. Even after hours, most practices have a way to reach an on-call provider who can tell you exactly where to go and how urgent it is.

Quick Reference: What to Do in the Most Common Dental Emergencies

Knocked-out permanent tooth: Hold by the crown, not the root. Rinse briefly with milk if dirty. Store in cold milk. Get to a dentist within 30 to 60 minutes.

Knocked-out baby tooth: Do not try to reimplant it. Call your dentist to have the area examined.

Chipped or cracked tooth: Save any pieces. Avoid hard foods. Call your dentist within 24 hours, even without pain.

Tooth pain: Give ibuprofen or acetaminophen by mouth in the correct dose. Use a cold compress on the cheek. Call your dentist. Skip the Orajel.

Bleeding from the mouth: Apply firm pressure with a clean cloth for 15 to 20 minutes. If bleeding does not stop, go to the ER.

Contact your dentist: Reach out to your dentist as soon as possible for guidance.

Conclusion

Dental emergencies with kids are stressful, and nobody expects you to have a dental degree when one happens. But a little advance knowledge goes a long way. Reach for milk instead of water. Skip the Orajel. Call your dentist before heading to the ER. Small things like these can make a real difference in how the situation turns out.

Frequently Asked Questions

What counts as a pediatric dental emergency? 

A dental emergency is anything that involves severe pain, uncontrolled bleeding, a knocked-out or severely displaced tooth, signs of infection such as swelling or fever, or trauma to the face or jaw. If you're unsure whether something qualifies, call your dentist and describe what's happening. They can help you decide how quickly to be seen.

My child knocked out a tooth and I can't find it. What should I do? 

Call your dentist right away. If the tooth can't be located, your dentist will want to examine the socket and the surrounding teeth to rule out any fractures or embedded tooth fragments. In some cases, an X-ray is needed to confirm the tooth came out completely.

Is it okay to give my child ibuprofen before a dental appointment? 

Yes. Giving your child an appropriate dose of ibuprofen or acetaminophen before the appointment is perfectly fine and can help keep them more comfortable. Just let the dental team know what you gave and when.

Can a knocked-out tooth really be saved?

Yes, in many cases it can, especially if you act quickly and store it correctly. The window is roughly 30 to 60 minutes for the best chances of successful reimplantation. After an hour, the odds decrease significantly, though it is sometimes still worth attempting. Speed and proper storage are the two factors most within a parent's control.

What if my child is scared to go to the dentist after an injury? 

That's completely normal. A traumatic experience with a tooth can make kids anxious about dental visits. Let your dentist know before the appointment so the team can take extra time to explain what's happening, move at your child's pace, and make the visit as calm as possible. Pediatric dentists are specifically trained to work with anxious kids.

What if my child's tooth was pushed up into the gum instead of knocked out completely? 

This is called a tooth intrusion, and it looks alarming — the tooth appears to have disappeared or sunk into the gumline. Do not try to pull it back down. Leave it alone and call your dentist immediately. In young children, an intruded baby tooth will often re-emerge on its own over time, but it needs to be monitored closely to ensure it isn't affecting the permanent tooth developing beneath it.

My child swallowed the knocked-out tooth. Should I be worried? 

In most cases, no. A swallowed tooth will pass through the digestive system without causing harm. The bigger concern is whether it was inhaled into the airway rather than swallowed. If your child is coughing, wheezing, or having any difficulty breathing after a tooth is knocked out and can't be located, go to the ER right away. If they seem completely fine, a swallowed tooth is generally not a medical emergency, but do let your dentist know so they can document it.

What should I keep on hand at home for dental emergencies? 

A simple dental first aid kit goes a long way. Consider keeping a tooth preservation kit like Save-A-Tooth (mentioned in the knocked-out tooth section above and available at most pharmacies), children's ibuprofen and acetaminophen, gauze pads to control bleeding, and your dentist's after-hours number saved in your phone. You don't need much — just having the right storage medium for a knocked-out tooth and knowing the number to call puts you on the right track when there’s a sudden emergency.
