What to do for a knocked-out permanent tooth

It’s never pleasant to see your child knock out a tooth, but it’s even more unnerving when you realize that they’ve knocked out a permanent tooth. Here’s what you need to know about treating a knocked-out permanent tooth.

Apply a cold compress, like a cool, wet washcloth, to your child’s mouth to stop the bleeding and minimize swelling. If you can find their tooth, pick it up by the crown (the part that you usually see above your child’s gum line). Avoid touching the tooth’s root. Rinse the tooth with milk to clean it and gently push it back into the tooth socket. Have your child hold the tooth in place with gauze or a washcloth. If your child can’t or won’t hold the tooth in place, you can put the tooth in a cup of milk

Never put the knocked-out tooth in water; the water can damage the tooth’s roots, making it impossible to reattach. If milk isn’t available, saliva is your next-best option. Don’t put your tooth in milk alternatives, like almond milk or another plant-based milk, as these milk products don’t have the same pH as dairy milk.

When to seek care for a knocked-out permanent tooth

A knocked-out permanent tooth requires prompt emergency dental care. When you seek immediate care, it’s more likely that we’ll be able to successfully reattach your child’s tooth. Try to seek emergency dental care within 30 minutes to optimize your chances of saving your child’s tooth.

When in doubt, call 911 immediately

In a pediatric emergency, it's essential to act quickly and seek medical help immediately. When faced with a situation where a child's health or life may be at risk, it's better to err on the side of caution and call 911 right away. Delaying treatment can worsen the condition and make it more difficult to save the child.
