What to do if tooth falls out
If an adult tooth is knocked out, hold it by the crown, keep it moist, and seek urgent dental care for possible replantation.
The short answer
If an adult tooth is knocked out, hold it by the crown, keep it moist in milk or saliva, and seek urgent dental care immediately. Do not scrub the root or wrap it in a dry tissue.
What happens to an adult tooth after it is completely displaced?
A completely displaced adult tooth is an avulsed tooth, and the periodontal ligament cells on its root may be injured outside the mouth. A baby tooth should not be pushed back into its socket because it can affect the developing adult tooth.
How should you handle and protect a knocked-out tooth?
Find the tooth, lift it by the white crown, and gently rinse visible dirt without rubbing the root; if it can be placed back without force, keep it seated and bite softly on clean gauze. Otherwise place it in milk or inside the cheek only if the person is alert and old enough not to swallow it, then bring it to the dental team.
Why does a knocked-out adult tooth need immediate care?
Treat an adult tooth knocked out as urgent, especially after a blow to the face, and seek care immediately. Go to emergency medical care for heavy bleeding, loss of consciousness, vomiting, breathing difficulty, or a suspected jaw injury.
What should you ask about replacing the knocked-out tooth?
Ask whether the tooth can be replanted, whether the socket or neighboring teeth are fractured, and whether a flexible splint is needed. Ask how the tooth will be monitored for pulp or root complications and what replacement options apply if it cannot be saved.
Frequently asked questions
Should I clean a knocked-out tooth?
Rinse it gently if dirty, but do not scrub the root or use disinfectant.
What if the tooth is loose rather than out?
Do not pull or test it repeatedly; protect it from further force and obtain urgent dental assessment.
