A knocked out permanent tooth in a child is time-sensitive

If your child lost a permanent tooth after injury, the first hour matters most. In many cases, a dentist may be able to reimplant the tooth, especially when it is handled carefully and treated quickly. This page helps parents understand what to do for a knocked out adult tooth in a child, how to save a knocked out permanent tooth when possible, and when to contact an emergency dentist right away.

What to do right away

Find the tooth and pick it up by the crown

Hold the tooth by the chewing surface or top part, not the root. Touching the root can damage important cells needed for successful reimplantation.

If dirty, rinse gently for a few seconds

Use milk or saline if available, or a brief gentle rinse with water. Do not scrub, dry, wrap in tissue, or use soap.

Get emergency dental care as soon as possible

A child knocked out permanent tooth emergency should be seen urgently. If a dentist is not immediately available and there are other serious injuries, seek emergency medical care.

How to save a knocked out permanent tooth

Best option: place it back in the socket if advised and possible

If the child is calm, the tooth is a permanent tooth, and it can be positioned correctly, immediate reimplantation may help. Bite gently on clean gauze afterward. If you are unsure, get urgent professional guidance.

If not reinserted, keep the tooth moist

Store it in cold milk, saline, or inside the child's cheek only if the child is old enough not to swallow it. Do not let the tooth dry out.

Bring the tooth to the dentist immediately

Even if the tooth cannot be placed back in the mouth, bringing it quickly and stored properly gives the dentist the best chance to help.

When to get urgent help beyond the tooth

Heavy bleeding that does not slow

Apply gentle pressure with clean gauze. If bleeding is significant or continues, seek urgent medical attention.

Possible head, face, or jaw injury

If your child has vomiting, confusion, severe swelling, trouble opening the mouth, or facial injury, medical evaluation is important right away.

You are not sure whether it is a baby tooth or permanent tooth

Do not force a tooth back in if you are uncertain. Answer a few questions in the assessment for personalized guidance on what to do next.

Frequently Asked Questions

What should I do if my child knocked out a permanent tooth?

Act quickly. Find the tooth, hold it by the crown, rinse gently only if dirty, keep it moist, and contact an emergency dentist for a knocked out permanent tooth right away. The sooner your child is seen, the better the chance of saving the tooth.

Can a knocked out permanent tooth be saved?

Sometimes, yes. A permanent tooth has the best chance of being saved when it is handled carefully, kept moist, and treated within the first 30 to 60 minutes. Dry time and rough handling lower the chance of successful reimplantation.

Milk is a common option. Saline is also appropriate. The goal is to keep the tooth moist. Avoid storing it dry in tissue or cloth.

You should still seek emergency dental care. Even if the chance of saving the tooth is lower after an hour, a dentist still needs to examine the area, check for other injuries, and discuss the next steps.
