A Parent's Guide to Dental Emergencies for Kids

Dental emergencies never happen at a convenient time for families in Garden City, Williston Park, or anywhere else on Long Island. It’s the playground fall right before dinner, the bike accident on a Sunday, or the toothache that shows up at 2 a.m. In the moment, it’s hard to know whether you’re dealing with something that can wait until morning or something that needs attention right now. Here’s a practical, save-it-for-later guide to the most common pediatric dental emergencies and exactly what to do for each one.

Knocked-Out Tooth: Baby Tooth vs. Permanent Tooth

This is the one distinction that matters most, and it’s also the one parents most often get backwards.

If it’s a permanent tooth: time is critical. Find the tooth and pick it up by the crown (the white chewing part), never the root. If it’s dirty, rinse it gently with water, don’t scrub it or use soap. If possible, gently reinsert it into the socket and have your child hold it in place by biting down on clean gauze or a washcloth. If reinsertion isn’t possible, keep the tooth moist in a container of milk (or have your child hold it between their cheek and gum if they’re old enough not to swallow it) and get to a dentist immediately. The window for successfully saving a permanent tooth is generally within about an hour of the injury.

If it’s a baby tooth: do not try to put it back in. Reinserting a primary tooth can actually damage the permanent tooth developing underneath it. Instead, control any bleeding with light pressure from clean gauze, keep your child calm, and call your pediatric dentist to be seen. It’s still worth a visit, both to check that no fragments remain and to make sure the permanent tooth bud wasn’t affected by the injury.

Chipped or Broken Tooth

Rinse your child’s mouth gently with warm water to clear the area, and if you can find the broken piece, save it and bring it with you. Apply a cold compress to the lips or cheek if there’s swelling. Chipped teeth don’t always hurt right away, but they should still be seen fairly promptly, since a crack that looks minor can expose the inner layers of the tooth to bacteria and lead to infection if left untreated.

Sudden Toothache

Rinse the mouth with warm water and gently floss around the painful tooth in case something is trapped there, that alone resolves more toothaches than parents expect. A cold compress on the outside of the cheek can help with swelling or discomfort. Avoid the old home remedy of putting aspirin directly on the gum or tooth; it doesn’t relieve pain that way and can actually burn and damage the gum tissue. If the pain doesn’t ease up, or if you notice swelling, fever, or a bad taste that suggests infection, call your dentist rather than waiting it out.

Bitten Tongue or Lip

These look alarming because mouths bleed a lot, but most are manageable at home. Clean the area gently with water and apply a cold compress to control swelling and bleeding. If bleeding doesn’t slow down after about 10 to 15 minutes of steady pressure, or if the cut is deep or gaping, that’s a sign to seek care at a dentist or emergency room rather than continuing to wait.

Object Caught Between Teeth

Try gently removing it with dental floss first. Avoid sharp or pointed objects like a pin or knife tip, since they can injure the gums or push the object in further. If floss doesn’t work, it’s better to leave it and call your dentist than to keep trying at home.

When to Go to the ER Instead of the Dentist

Most dental emergencies are best handled by your pediatric dentist, even after hours, since many keep time reserved for emergency patients or have an after-hours line. A trip to the emergency room makes more sense when there’s a possible broken jaw or facial bone, bleeding that won’t stop with steady pressure, a head injury alongside the dental injury, or any trouble breathing or swallowing. When in doubt about which one applies, calling your dentist’s emergency line first is a reasonable way to get guided to the right place.

Build a Simple Dental Emergency Kit at Home

A few things kept together, maybe in a small bag in a bathroom cabinet, make a real difference in the first chaotic minutes of an emergency:

• Your pediatric dentist’s phone number, including their after-hours or emergency line, saved somewhere you’d actually find it under stress
• Clean gauze or a soft cloth
• A small container with a lid, for storing a knocked-out tooth in milk if needed
• A cold pack or something that can double as one

Having this ready ahead of time is part of what having an established dental home is for. If your child already has a regular pediatric dentist, you’re not scrambling to find one while also managing an injury.

Frequently Asked Questions

Should I try to put my child’s knocked-out tooth back in?

It depends on whether it’s a permanent tooth or a baby tooth. A permanent tooth should be gently reinserted if possible, or stored in milk, and seen by a dentist within about an hour. A baby tooth should not be reinserted; instead, control bleeding and call your dentist.

Is a chipped tooth a dental emergency?

It depends on severity, but it’s always worth a prompt call to your dentist. Even a small chip can expose the inner tooth to bacteria and should be evaluated rather than left alone.

Can I give my child aspirin for a toothache?

Not applied directly to the gum or tooth. Doing so can burn and damage the gum tissue. Oral pain relief should be given as directed by your pediatrician or dentist, not placed against the sore spot.

When should I go to the emergency room instead of calling the dentist?

Go to the ER for a possible broken jaw, bleeding that won’t stop with steady pressure, a head injury along with the dental injury, or any trouble breathing or swallowing. Most other dental emergencies, including a knocked-out or chipped tooth, are better handled by a dentist.

What’s the most important thing to do in any dental emergency?

Stay calm, control any bleeding with gentle pressure, and call your pediatric dentist right away. Having their number saved ahead of time, along with knowing the difference between a baby tooth and permanent tooth emergency, makes the biggest difference in the first few minutes.
