Call your dentist first
For a broken tooth, a lost filling or bad tooth pain, call your dentist. The American Dental Association says most dentists set aside time for emergencies.
If you do not have a dentist, look for an office that says it sees same-day emergencies. The list below comes from what offices say on their own websites, so call before you go.
If a tooth is knocked out
For an adult tooth that has been knocked out, the American Dental Association says:
- Keep it moist.
- If you can, put it back in the socket without touching the root.
- If it will not go back, hold it between your cheek and gum, or put it in milk or a tooth-preservation product with the ADA Seal.
- Get to a dentist right away.
When to go to the ER instead
Go to the emergency room or call 911 if you have:
- Trouble breathing or swallowing
- Swelling that is spreading quickly
Also go to the ER if your dentist’s office is closed and you cannot reach anyone, and the problem cannot wait.
After-hours and weekend care
Some Maryland offices say they answer emergency calls after hours, and some are open on weekends. Our list of dentists open on Saturdays can help if a problem starts at the end of the week.
