Dental problems rarely happen at convenient times. A cracked tooth on a Saturday or a swollen jaw late at night raises a practical question: do you need help right now, or can this wait until the office opens? This guide helps you sort urgent situations from ones that can wait, explains sensible first steps, and shows where to go if your regular dentist is not available.
First, the most important rule: if you have trouble breathing or swallowing, swelling spreading toward your eye or neck, heavy bleeding that will not stop, or a significant injury to the face or jaw, call 911 or go to a hospital emergency room. These can be medical emergencies, not just dental ones.
What usually counts as a dental emergency
Dental emergencies generally involve severe pain, signs of infection, uncontrolled bleeding, or an injury where quick action can save a tooth. Common examples:
- A knocked-out adult tooth. Time matters.
- Facial or gum swelling, especially with fever, a bad taste or a pimple-like bump on the gum, which can signal an abscess.
- Severe, persistent toothache that over-the-counter pain relief does not control.
- A tooth pushed out of position or loosened by an injury.
- Bleeding that will not stop after an extraction or injury, even with firm pressure.
- A badly cracked or broken tooth with sharp pain.
What can usually wait for a regular appointment
Some problems are uncomfortable but not urgent. Call your dentist when the office opens:
- A small chip with no pain.
- A lost filling, or a crown that has come off, if you are not in significant pain. Keep the crown safe.
- Mild sensitivity to hot or cold.
- A dull ache that comes and goes and responds to over-the-counter pain relief.
- A broken or ill-fitting denture, unless it has caused an injury.
“Can wait” does not mean “ignore.” Mild symptoms can be early signs of a problem, such as an inflamed pulp that may later need a root canal.
First steps for common situations
The tips below follow the guidance published by the American Dental Association on its MouthHealthy dental emergencies page.
Knocked-out permanent tooth
Handle the tooth by the crown (the part you normally see), not the root, and keep it moist at all times. If you can, place it back in the socket. If that is not possible, hold it between your cheek and gum, put it in milk, or use a tooth preservation product with the ADA Seal. Then get to a dentist right away. Do not try to reinsert a baby tooth; call your child’s dentist instead.
Cracked tooth
Rinse your mouth with warm water to clean the area and put a cold compress on your face to limit swelling. Contact a dentist promptly.
Bitten tongue or lip
Clean the area gently with water and apply a cold compress. If the bleeding does not stop with pressure, seek urgent care.
Toothache
Rinse with warm water and use dental floss gently to remove any trapped food. The ADA specifically advises not putting aspirin on the aching tooth or gums.
Object stuck between teeth
Try gently removing it with floss. Do not use sharp or pointed instruments.
Where to go when your dentist is closed
- Call your regular dentist anyway. The ADA notes that most dentists reserve time in their daily schedules for emergency patients. Many offices also have an after-hours message with instructions.
- Look for a practice that offers same-day or weekend care. Our directory lists dental practices by state and city. Los Angeles readers can use our Los Angeles emergency dentist page. Always call ahead to confirm the office can see you.
- Use the hospital emergency room for medical red flags. ERs can manage spreading infection, airway concerns, serious bleeding and facial trauma. Many cannot provide definitive dental treatment such as a filling or root canal, so you will still need a dentist afterward.
- Consider a community health center. Some federally funded health centers have dental clinics with sliding-scale fees. Use the HRSA Find a Health Center tool and call to ask about urgent dental appointments.
What to tell the office when you call
Clear details help the team triage you correctly:
- Which tooth or area is affected and when the problem started.
- Whether there is swelling, fever, bleeding, or trouble opening your mouth.
- Whether a tooth was knocked out, and how you are storing it.
- Your medical conditions, current medications and allergies.
- Your insurance or Medicaid information. Adult Medicaid dental benefits vary by state (Medicaid.gov), so ask whether the office accepts your plan.
Preventing the next emergency
Not every emergency can be prevented, but some habits lower the odds. The ADA recommends wearing a mouthguard for sports, avoiding chewing ice, popcorn kernels and hard candy, and using scissors instead of your teeth to open packages. Regular checkups also help catch decay or cracks before they become painful. Our guide to how often to see the dentist explains how visit frequency is decided.
Frequently asked questions
Is a toothache an emergency?
A severe toothache that over-the-counter pain relief does not control, or one with swelling or fever, should be seen urgently. A mild, intermittent ache can usually wait for a regular appointment.
What should I do with a knocked-out tooth?
Hold it by the crown, keep it moist, try to place it back in the socket or store it in milk or between your cheek and gum, and see a dentist right away.
Should I go to the ER for a dental problem?
Go to the ER or call 911 for trouble breathing or swallowing, rapidly spreading swelling, uncontrolled bleeding or facial trauma. For other problems, a dentist is usually the better choice.
Can a lost crown wait until Monday?
Often yes, if you are not in significant pain. Keep the crown somewhere safe and call your dentist when the office opens.
