A dental injury is one of those things nobody plans for. A fall, a hit during sports, a bite into something harder than expected, and suddenly you or your child is holding a broken tooth wondering what happens next. What you do in the first 30 to 60 minutes can make the difference between saving a tooth and losing it permanently.
Here’s what to do, step by step.

If a Tooth Is Completely Knocked Out
- Find the tooth and pick it up by the crown (the white part), never the root. Touching the root can damage the cells needed to reattach it.
- Rinse it gently with milk or saline if it’s dirty. Do not scrub it, use soap, or let it dry out. Do not wrap it in a tissue or paper towel.
- Try to reinsert it into the socket facing the right direction and have the person gently bite down on clean gauze or a cloth to hold it in place. If that’s not possible, keep it moist: submerge it in milk, saliva, or a store-bought tooth preservation solution.
- Get to a dentist within 30 minutes if at all possible. The chance of successfully saving the tooth drops significantly after the first hour outside the mouth.
Never store a knocked-out tooth in plain water. It damages the root surface.
If a Tooth Is Broken, Chipped, or Cracked
- Rinse the mouth with warm water to clear away blood or debris.
- Save any broken pieces if you can find them, keeping them moist in milk or saliva.
- Apply a cold compress to the outside of the face or lips to reduce swelling.
- Control bleeding with gentle pressure from clean gauze if the gums or lip are cut.
- Avoid chewing on that side and skip very hot, cold, or sugary foods until it’s evaluated. A cracked tooth can be more sensitive to temperature and pressure than it looks.
General First Aid Tips for Any Dental Injury
- Over-the-counter pain relief (like ibuprofen or acetaminophen) can help manage discomfort while you get to care.
- Do not put aspirin directly on the tooth or gums. It doesn’t help and can burn the tissue.
- If there’s a cut on the lip, tongue, or inside the cheek along with the tooth injury, that needs to be checked too.
- Watch for signs that need urgent attention: heavy bleeding that won’t stop, facial swelling that’s spreading, or a fever, which can point to infection.
When to Go to the ER vs. a Dentist
Most tooth injuries, including knocked-out and broken teeth, are best handled by a dentist who can actually treat the tooth, not just stabilize you. Emergency rooms are the right call for uncontrolled bleeding, a possible broken jaw, a head injury, or if you can’t reach a dentist and it’s after hours. Otherwise, a same-day dental visit gets you faster, more targeted treatment, often at a lower cost than an ER trip.
The Bottom Line
Time matters more than almost anything else with a dental injury. Keep the tooth moist, keep pressure off it, and get seen as quickly as you can. The faster the tooth gets professional attention, the better the odds of saving it.
If you’re dealing with a dental emergency, Dental ERx offers same-day appointments for exactly these situations. Call ahead so we can have everything ready when you arrive.
What should I do if my permanent tooth gets knocked out?
Pick up the tooth by the crown, gently rinse it if dirty, and try to place it back into the socket if possible. If you cannot reinsert it, keep it moist in milk, saliva, or a tooth-preservation solution and see a dentist as soon as possible.
Can a knocked-out tooth be saved?
Yes, a knocked-out permanent tooth may be saved if it receives prompt dental treatment. The sooner the tooth is placed back in the socket or preserved properly, the better the chances of saving it.
What should I do with a broken or chipped tooth?
Rinse your mouth gently, save any broken pieces in milk or saliva, apply a cold compress to reduce swelling, and avoid chewing on the injured side until a dentist can examine the tooth.
Should I go to the ER or a dentist for a broken tooth?
Most broken or knocked-out teeth should be treated by a dentist. Go to the ER if there is uncontrolled bleeding, a suspected broken jaw, a serious head injury, significant facial swelling, or another condition requiring immediate medical attention.
How quickly should I see a dentist after a dental injury?
You should seek dental care as soon as possible, especially if a permanent tooth has been knocked out. Ideally, get professional care within 30 minutes when possible, as the chances of saving the tooth decrease the longer it remains outside the mouth.
