A knocked-out tooth is one of the few dental situations where minutes genuinely matter. What you do in the first half hour can directly affect whether the tooth has a chance of being saved.
If this has just happened to you or someone nearby, here's exactly what to do, step by step.
Step One: Find The Tooth
Handle It By The Crown, Not The Root
Pick the tooth up by the crown, the visible chewing surface, not the root, which contains delicate tissue essential for reattachment.
Avoid Scrubbing Or Cleaning It Aggressively
If dirty, gently rinse with water or milk for a few seconds. Don't scrub it, use soap, or wrap it in a towel.
Step Two: Try To Reinsert It, If Possible
Why Reinsertion Gives The Best Chance Of Success
If you're able to, gently place the tooth back into its socket facing the correct direction.
If Reinsertion Isn't Possible
That's okay. Move directly to keeping it in a safe, moist environment instead.
Step Three: Keep The Tooth Moist At All Times
Why A Dry Tooth Is A Bigger Problem
Root surface cells can die quickly if the tooth dries out, lowering the chances of reattachment.
Best Options For Storage
- Milk, one of the most readily available and effective options
- A tooth preservation kit, if available
- Saline solution, if on hand
- The inside of your cheek, only if the person is alert enough to avoid swallowing it
What To Avoid
Don't store the tooth in tap water or a dry tissue or paper towel.
Step Four: Get To A Dentist As Quickly As Possible
Why Time Is The Most Important Factor
The chances of saving the tooth decrease significantly the longer it's out of the mouth.
Call Ahead If You Can
Call your dentist's office on the way so they can prepare for your arrival.
What Happens When You Arrive At The Dentist
Evaluating The Tooth And Socket
Your dentist examines the tooth and socket to determine whether reattachment is viable.
Reattachment, If Possible
If the tooth is a good candidate, your dentist cleans the area and repositions it, often stabilizing it with a splint while it heals.
Next Steps If Reattachment Isn't An Option
If the tooth can't be saved, your dentist will discuss replacement options, which may include a dental implant.
What If It's A Baby Tooth Instead Of A Permanent One
Baby teeth are generally not reinserted, since doing so can risk damaging the developing permanent tooth underneath. Still, contact a dentist to check for additional injury.
Common Situations Where This Happens
Sports-related injuries are one of the most common causes, which is part of why a properly fitted mouthguard is worth discussing if you or your child plays sports. Falls, particularly in young children, are another frequent cause.
FAQs
How long do I have before a knocked-out tooth can't be saved?
The chances decrease the longer it's outside the mouth, which is why getting to a dentist quickly matters so much.
Can I put a knocked-out tooth back in myself?
If comfortable, gently reinserting it can help, but it's not required. Keeping it moist and getting to a dentist quickly matters most either way.
What should I store the tooth in if I can't get to a dentist right away?
Milk is one of the best and most accessible options.
Should baby teeth be reinserted the same way as adult teeth?
No. Baby teeth are typically not reinserted, since it can risk the developing permanent tooth underneath.
What if the tooth breaks instead of coming out completely?
The same urgency applies. Timely treatment can affect outcomes for broken teeth too.
