Tooth injuries happen in an instant — a sports collision, a fall, or biting down on something hard. What you do in the minutes that follow can make the difference between saving and losing a tooth.
This guide explains the first-aid steps for two common injuries, a chipped tooth and a knocked-out tooth, and when to find an emergency dentist near you.
First aid for a chipped or cracked tooth
- Rinse your mouth with warm water to clean the area.
- Save any pieces of the tooth if you can, and keep them moist.
- Use a cold compress on the outside of the cheek to reduce swelling.
- Cover a sharp edge with dental wax or sugar-free gum to protect your tongue and cheek.
- See a dentist promptly to assess the damage and discuss repair options.
For longer-term repair choices once the emergency is handled, our guide on fixing chipped or cracked teeth covers bonding, veneers, and crowns.
First aid for a knocked-out tooth
A knocked-out permanent tooth is a true emergency, and acting fast matters. Pick up the tooth by the crown (the top), never the root. Gently rinse it if it is dirty, but do not scrub it. If possible, place it back in the socket and hold it there. If you cannot, keep it moist in milk or in your cheek pouch, and see a dentist immediately — ideally within the hour.
Why speed matters
For a knocked-out tooth, the chances of successful re-implantation are highest when it is treated within about an hour. This is why knowing how to reach an emergency dentist quickly — and understanding what to do right now — is so important.

Frequently asked questions
What should I do if my tooth gets knocked out?
Pick it up by the crown, not the root, rinse gently without scrubbing, and try to place it back in the socket. If you can't, keep it moist in milk or your cheek and see a dentist within the hour.
Is a chipped tooth an emergency?
A small chip may not be urgent, but a large chip with pain, bleeding, or a sharp edge should be seen promptly. Save any pieces, protect the area, and contact your dentist.
How quickly do I need to see a dentist for a knocked-out tooth?
As soon as possible, ideally within an hour. The sooner the tooth is treated, the better the chance it can be successfully re-implanted.
