A Knocked-Out Tooth: Why Identifying Adult or Baby Matters
A tooth knocked out during an accident needs urgent attention, but guidance differs for a permanent tooth and a baby tooth. Do not assume that every tooth should be put back. Contact a dentist immediately and explain the person’s age and which tooth is missing.
Handle a permanent tooth carefully
For a knocked-out adult tooth, hold the crown rather than the root and keep it moist. If it can be gently replaced without force, that may be appropriate; otherwise milk or an approved tooth-preservation medium can help during urgent travel to care. Do not scrub the root or let the tooth dry out.
Avoid replacing a baby tooth
A baby tooth should not be replanted because of risk to the developing permanent tooth. A dentist still needs to evaluate the injury and surrounding tissues. Serious head injury, loss of consciousness, breathing difficulty, or uncontrolled bleeding requires emergency medical help. Quick professional guidance matters because the visible missing tooth may be only one part of the injury, and the right immediate action depends on which type of tooth was lost.
