If a permanent tooth gets knocked out, act quickly. Retrieve the tooth, hold it by the crown, and rinse it gently if it’s dirty. Place it back in the socket if possible, or keep it moist in milk, then see a dentist immediately.
Retrieve the Tooth Carefully
When handling a knocked-out tooth, it’s crucial to treat it gently. Hold the tooth by the crown, which is the white part typically visible in the mouth, not the root.
- If the tooth is dirty, rinse it briefly with water. Do not scrub or remove any tissue fragments.
- Avoid using soap or chemicals.

Attempt to Reinsert the Tooth
If you can, try to place the tooth back into its socket in the mouth. Align it correctly with the other teeth and press it gently into place.
- Hold the tooth with a soft cloth or gauze and bite down gently to keep it stable.
- If reinserting the tooth is not possible, do not force it.
Keep the Tooth Moist
Proper moisture is vital for the survival of the tooth. If reinsertion fails, keeping the tooth moist is essential.
- Place the tooth in a container of milk.
- If milk is unavailable, use the person’s saliva or saline solution.
- Avoid storing the tooth in water.
“A tooth has the best chance of survival if it’s back in its socket within an hour.”
Seek Immediate Dental Care
Time is of the essence when it comes to dental trauma. Contact a dentist right away. If you’re near a major city, consider visiting a local clinic such as Toronto or Calgary to ensure timely care.
Explain the situation clearly and follow the dentist’s instructions promptly.
Understand the Risks
Even with prompt action, reimplantation may not always be successful. Factors affecting success include the time the tooth is out of the mouth and the care taken to preserve it.
Regular check-ups and following the dentist’s advice are essential for the best outcome.

Frequently asked questions
What should I do if I can't fit the tooth back in the socket?
If you can't reinsert the tooth, keep it moist in milk, saliva, or saline solution, and see a dentist as soon as possible to improve the chances of saving the tooth.
How long can a tooth survive outside the mouth?
A tooth has the best chance of being saved if it's reimplanted within an hour. The longer it stays out, the less likely it is to be successfully reattached.
Why shouldn't I store the tooth in water?
Storing a tooth in water can damage the root cells necessary for reattachment. Milk or saliva helps preserve these cells better.
Can I use any kind of milk to store the tooth?
Whole milk is preferred because its composition is closest to natural saliva, helping to maintain the viability of the root cells.
