| Quick Summary |
| Who this is for: Anyone dealing with a knocked-out, broken, or fractured tooth from an accident, fall, or sports injury who needs to know exactly what to do right now. |
| Key takeaways: A knocked-out adult tooth can sometimes be saved, but only within about 60 minutes. Handling it wrong closes that window fast. A broken tooth with jagged edges or exposed pulp needs same-day care. How you store the tooth and what you do in the first few minutes makes a measurable difference in outcomes. |

Most dental situations give you time. A cavity can wait a few days for an appointment. Sensitivity from a lost filling is uncomfortable but not urgent. Dental trauma is different.
A tooth knocked out during a soccer game, a fall, or an accident operates on a clock. The same goes for a badly fractured tooth exposing the inner pulp. What you do in the first 30 minutes, before you even reach a dentist, directly affects what is still possible when you get there.
This post covers exactly what to do, step by step, for the two most common types of dental trauma: a knocked-out tooth and a broken or fractured tooth.
When a Tooth Gets Knocked Out: The 60-Minute Window
A knocked-out tooth is called an avulsion. It is the most time-sensitive situation in dentistry. The periodontal ligament fibers that attach the tooth to the jawbone begin to die within minutes of the tooth leaving the socket. The sooner those fibers stay viable, the better the chances of successful re-implantation.
Here is what the research actually shows: teeth re-implanted within 30 minutes have the highest success rates. Between 30 and 60 minutes, success rates drop but re-implantation is still attempted. After two hours, the prognosis is poor.
That is your window. Sixty minutes. Probably less.
Step 1: Find the Tooth and Handle It Correctly
Pick the tooth up by the crown, which is the white part you normally see in your mouth. Do not touch the root. The root is covered in those periodontal ligament fibers, and touching or scrubbing them damages what you are trying to preserve.
If the tooth is dirty, rinse it very gently under cold water for no more than 10 seconds. Do not scrub it. Do not dry it. Do not wrap it in a dry cloth or tissue.
Step 2: Try to Reinsert It
This sounds alarming, but it is the best option if possible. Gently place the tooth back into its socket, crown first, and bite down softly on a piece of gauze or a clean cloth to hold it in position. If it goes back in, the environment of the mouth is actually the best place for it while you get to the dentist.
If that is not possible, or if you are dealing with a child and are concerned about swallowing, move to step 3.
Step 3: Store It Properly
Storage medium matters a lot. Here is the ranking from best to worst:
- Milk. Cold milk is the best widely available storage option. It maintains the right pH and osmolarity to keep the cells alive.
- Saline solution. Similar to milk in effectiveness if you have it on hand.
- The patient’s own saliva. Holding the tooth in the cheek or under the tongue works if milk is not available, but there is a risk of swallowing it.
- Water. Last resort. It is hypotonic and damages the cells, but it is better than dry storage.
- Dry storage, paper towels, or tissues. Do not do this. The tooth dries out and the cells die quickly.
Step 4: Get to a Dentist Immediately
Call ahead if you can. The emergency dentistry team at Pioneer Valley Dental in West Valley City makes room for urgent situations. Calling on the way means the team is ready when you arrive, which matters when you are working against a clock.
If you are dealing with this right now, here is a quick visual walkthrough of the steps:

What Happens When You Arrive
The dentist will take an X-ray to assess the socket and surrounding bone. If the tooth is viable, it will be reinserted and splinted to adjacent teeth for two to four weeks while the ligament reattaches. A follow-up appointment checks for complications, including pulp death, which sometimes requires root canal treatment weeks later even in successful re-implantations.
If the tooth cannot be saved, the conversation will shift to replacement options. Dental implants are the most durable long-term solution. A bridge is another option. The dentist will walk you through what makes sense based on the location and condition of the socket.
Broken and Fractured Teeth: How Serious Is It?
Not every broken tooth is the same emergency. The severity depends on how deep the fracture goes.
Surface Chips and Minor Fractures
A small chip off the enamel with no pain and no sharp edges is the least urgent scenario. You should get it seen within a few days, but it is not a 911 situation. Avoid anything very hard or crunchy on that side until you do.
If the chip left a sharp edge cutting your tongue or the inside of your cheek, cover it with dental wax, orthodontic wax, or even a piece of sugarless gum until you can get in.
Fractures That Reach the Dentin
When a break goes deeper than the enamel into the dentin layer, sensitivity to temperature and pressure increases significantly. This needs to be seen within 24 to 48 hours. The tooth is vulnerable to further damage and bacterial infiltration.
Fractures That Expose the Pulp
The pulp is the soft tissue at the center of the tooth containing nerves and blood vessels. If you can see a reddish dot in the center of the break, or if the pain is severe and continuous rather than sensitivity-triggered, the pulp is likely exposed. This is a same-day situation.
An exposed pulp left untreated becomes infected. That infection does not resolve on its own. The treatment at this stage typically involves either a pulp cap procedure if caught early enough, or a root canal if the pulp is already infected.
Vertical Root Fractures
These are fractures that run lengthwise down the root, often invisible to the eye but causing dull, hard-to-localize pain. They are among the most serious fractures and frequently result in extraction because there is no way to stabilize a root split down its length. They tend to develop slowly from grinding or from biting into something very hard.
What to Do for a Broken Tooth Before You Get Seen
- Rinse your mouth with warm water to clean the area.
- Apply a cold compress to the outside of your cheek to manage swelling.
- Cover sharp edges with dental wax or sugarless gum to protect soft tissue.
- Take over-the-counter ibuprofen or acetaminophen as directed for pain.
- Do not place aspirin directly on the tooth or gum. This causes chemical burns.
- Avoid hot, cold, sweet, or very hard foods on that side.
Save any pieces of the tooth if you can find them. In some cases, particularly with front teeth, a fragment can be bonded back onto the tooth.
Dental Trauma in Kids vs. Adults
One important distinction: the approach to a knocked-out baby tooth is different from an adult tooth. Baby teeth are generally not re-implanted because forcing the primary tooth back into the socket can damage the developing permanent tooth underneath.
If a child loses a baby tooth from trauma, the main concerns are controlling bleeding, managing pain, and protecting the space until the permanent tooth comes in. A dentist still needs to see the child to assess whether the root was fully displaced and whether there is any damage to the underlying permanent tooth.
For adult teeth, every minute counts. The protocol described above applies.
Sports and Accident Prevention
Most dental trauma is preventable. A properly fitted mouthguard absorbs shock and keeps teeth from making contact with other teeth, hard surfaces, or blows during contact sports. Studies show mouthguards reduce the risk of dental injury by up to 60 times compared to playing without one.
Over-the-counter boil-and-bite mouthguards offer basic protection. Custom mouthguards made by a dentist fit better, offer more consistent protection, and are less likely to interfere with breathing or communication during play.
Pioneer Valley Dental can fit you or your child for a custom mouthguard as part of their general dental services. One appointment can prevent years of dental trauma management.

Frequently Asked Questions About Knocked-Out and Broken Teeth
1. Can a knocked-out tooth really be saved?
Yes, if you act fast. Adult teeth re-implanted within 30 minutes have the best outcomes. After 60 minutes, the prognosis drops sharply. Storage in cold milk or saline while you get to the dentist is critical.
2. What if I swallow the knocked-out tooth?
A swallowed tooth typically passes without issue. More pressing is getting to the dentist quickly to discuss replacement options, since re-implantation is no longer on the table.
3. Do baby teeth get re-implanted after being knocked out?
Generally no. Re-implanting a primary tooth can interfere with the developing permanent tooth beneath it. The goal shifts to managing the space and monitoring the underlying permanent tooth.
4. How do I know if my broken tooth is a dental emergency?
Severe continuous pain, visible reddish tissue at the break, or a break that goes below the gumline are all signs of an emergency. A small chip with no pain can wait a day or two. When in doubt, call the office and describe what you see.
5. Will I need a root canal after a knocked-out tooth is re-implanted?
Often yes, within one to two weeks of re-implantation. The trauma that knocked the tooth out frequently severs the nerve and blood supply. Root canal therapy preserves the tooth structure even if the pulp is no longer vital.
6. What is dental wax and where do I get it?
Dental wax is a soft wax you press over sharp edges or orthodontic hardware to protect soft tissue. It is sold at most pharmacies near the oral care section. Orthodontic wax works the same way.
7. Can a cracked tooth heal on its own?
No. Tooth structure does not regenerate. A crack will not close itself, and stress from chewing typically makes it worse over time. Early treatment is almost always simpler and cheaper than delayed treatment.
8. How long does it take to get treated at Pioneer Valley Dental for an emergency?
Call ahead and describe your situation. The team prioritizes trauma cases and typically gets urgent patients in the same day. Hours are Monday through Thursday 8:00 AM to 6:00 PM and Friday 8:00 AM to 3:00 PM.
9. What if the tooth socket is bleeding heavily?
Apply firm, direct pressure with clean gauze or a clean cloth. Bite down on it. Most post-trauma socket bleeding slows within 15 to 20 minutes with consistent pressure. If it does not, that is an additional reason to seek care urgently.
10. Does a mouthguard really make that much difference?
Yes. The American Dental Association estimates that mouthguards prevent approximately 200,000 dental injuries per year in the US alone. A custom mouthguard from your dentist provides better fit and protection than a generic over-the-counter version.
