Knocked Out Baby Tooth What to Do

If your child's baby tooth gets knocked out, stop any bleeding with gentle pressure and call 1-888-771-7431 right away. Unlike permanent teeth, a knocked-out baby tooth should never be put back in the socket. According to the American Dental Association, you should keep the tooth moist and see a dentist as soon as possible to check for hidden damage and protect the adult tooth growing underneath.

Step 1. Control the bleeding and stay calm

When a baby tooth gets knocked out, the bleeding often looks scarier than it actually is. The socket has tiny blood vessels that may ooze for several minutes. Use a clean piece of gauze or a soft cloth, fold it, and have your child bite down gently on the spot. Hold steady pressure for about 10 minutes.

If gauze isn't handy, a damp tea bag works too. The tannins help constrict blood vessels. Don't let your child rinse or spit forcefully, since that can dislodge the clot. A little pink tint in the saliva over the next day is normal. If bright red blood keeps flowing after 20 minutes of direct pressure, call a dentist immediately. That might mean the injury goes deeper than just the tooth.

Step 2. Find the tooth but don't try to replant it

Pick up the tooth by the crown, the smooth white part that showed in the smile. Avoid touching the root. Rinse it briefly with milk or saline if it's dirty. Don't scrub it, and don't use tap water. The Children's Hospital of Philadelphia notes tap water's chlorine can harm the tiny cells on the root surface.

Here's the critical rule. Never try to put a baby tooth back into the socket. A baby tooth's root sits directly on top of the developing adult tooth. Forcing it back in can damage or even kill the permanent tooth underneath. That's why pediatric dentists almost never reimplant avulsed baby teeth.

Step 3. Store the tooth properly and get to a dentist

Even though you won't put it back, bring the tooth with you. Place it in a small container with milk, saliva, or saline solution. Milk works well because its pH and mineral content are close to teeth. You can also store it between your cheek and gums if you're careful not to swallow it.

The American Dental Association says the best chance for saving a permanent tooth is within 30 to 60 minutes. For a baby tooth, the urgency is about checking for hidden fractures, root fragments left behind, or injury to the jaw. A dentist will take an X-ray to see if any pieces remain and to monitor the adult tooth below.

What the dentist will do when you arrive

The dentist will first numb the area gently, then clean the socket to remove any debris. They'll take an X-ray to see if the entire root came out or if fragments are still inside. If pieces remain, they may need to remove them to prevent infection.

For a baby tooth that's completely gone, the dentist will discuss space maintenance. Baby teeth hold space for adult teeth. Losing one too early can cause neighboring teeth to drift, leading to crowding later. A space maintainer is a small, custom metal band that keeps the gap open. The cost for a space maintainer typically ranges from $200 to $500, depending on the type and location.

Pain relief and what to watch for at home

Over-the-counter pain relievers are safe if dosed correctly. Give your child ibuprofen (like Children's Motrin) at 5-10 mg per kilogram of body weight every 6-8 hours, or acetaminophen (Children's Tylenol) at 10-15 mg per kilogram every 4-6 hours. For a typical 30-pound toddler, that's about 100 mg of ibuprofen.

Apply a cold pack wrapped in a towel to the outside of the cheek for 15 minutes on, 15 minutes off. This reduces swelling and numbs the area. Offer soft, cool foods like yogurt or applesauce for the first day. Avoid straws, because suction can disturb the clot.

When to go to the emergency room instead

Most knocked-out baby teeth are not life-threatening. But head straight to the ER if your child shows any of these signs. Trouble breathing or swallowing means swelling could block the airway. Facial swelling that spreads toward the eye or down the neck may indicate a serious infection. A high fever over 101°F with increasing pain could signal an abscess forming.

If the injury involved a hard blow to the head, loss of consciousness, or vomiting, go to the ER to rule out a concussion. Dental injuries often happen with falls, and head trauma trumps tooth trauma.

Frequently asked questions

Will the adult tooth grow in normally?

Most of the time, yes. The adult tooth is deeper in the jaw and often escapes injury. According to the American Academy of Pediatric Dentistry, the dentist will monitor it with periodic X-rays to ensure it erupts on schedule and in the right position. Sometimes a knocked-out baby tooth can cause a minor disruption, like a white or yellow spot on the adult tooth's enamel. That's cosmetic and doesn't affect function.

Should I save the tooth for the Tooth Fairy?

Absolutely. After the dentist examines it, you can keep it. Rinse it with milk, let it air dry, and store it in a small box. Some parents write the date and story on the box. It's a tangible reminder that your child got through a scary moment.

How much does treatment usually cost?

Without insurance, an emergency visit for a knocked-out baby tooth often runs between $150 and $300 for the exam and X-ray. If a space maintainer is needed, add another $200 to $500. Many dental offices offer payment plans or sliding-scale fees for uninsured patients. When you call 1-888-771-7431, we can match you with a practice that fits your budget.

Can this be prevented?

Mouthguards are the best defense. The American Dental Association recommends a custom-fit mouthguard for any sport with contact or fall risk, including soccer, basketball, and gymnastics. You can buy boil-and-bite guards at the drugstore for around $20, or your dentist can make one that fits better for about $100 to $300. It's a worthwhile investment compared to the cost and stress of an emergency visit.
