A Knocked-Out Tooth: What to Do in the First 30 Minutes
A fall while playing, a cricket ball, a bike accident — and a tooth is out. Most people wrap it in a cloth or drop it in a glass of water and come the next day, by which time it is far too late. Handled correctly, that tooth can often be saved. Read this before you need it.
A permanent tooth knocked out — step by step
- Find it and pick it up correctly. Hold it only by the white crown. Do not touch the pointed root — that surface carries the living cells that reattach the tooth to bone.
- If dirty, rinse very briefly — in milk or saline, for no more than ten seconds. Do not scrub, do not use a brush, and never use soap or antiseptic.
- If you can, put it straight back. In older children and adults this is the best option. Ease it into the socket the right way round and bite gently on a clean handkerchief to hold it.
- If you cannot, store it properly. In order of preference: cold milk, then saline, then the patient's own saliva. Do not use the saliva option for young children, because of the risk of swallowing the tooth.
- Get to a dentist immediately. The first 30 minutes are the most valuable; chances fall sharply after an hour.
Why not water?
This is the single mistake that costs the most teeth. Clinging to the root surface are the living cells of the periodontal ligament, and reattachment depends entirely on keeping them alive.
Plain water is not balanced like body fluid. Placed in it, those cells swell, burst and die within minutes. Milk is close enough to body fluid to keep them viable for hours — and milk is available in nearly every home and shop, which is what makes it the practical choice.
A child's milk tooth
Here the rule reverses. A knocked-out baby tooth is not replanted, because pushing it back can permanently damage the developing permanent tooth beneath it. Control bleeding with gentle pressure on a clean cloth, apply a cold pack, and still bring the child in so the injury and surrounding teeth can be checked.
Chipped, loosened or displaced teeth
- A broken fragment: bring it in milk too — it can sometimes be bonded back on
- A loosened or shifted tooth: do not force it straight; come in the same day
- A tooth pushed up into the gum: serious, needs same-day attention
- A small chip with no pain: still worth checking, as cracks deepen later
When it is more than a dental problem
With facial injury, some signs mean hospital first: loss of consciousness or confusion, repeated vomiting, blood or clear fluid from the ear or nose, an inability to close the mouth properly, or a jaw that looks out of line. Seek emergency medical care before dental care.
Prevention, especially for children
- Use a mouthguard for cricket, kabaddi, cycling and contact sports
- Stop children running with objects in their mouths
- Children whose upper front teeth protrude are at markedly higher risk of injury — an early orthodontic assessment reduces that risk

Frequently Asked Questions
Can a knocked-out tooth be put back?
Yes. If a permanent tooth is knocked out cleanly and handled correctly, it can often be replanted. Success depends heavily on time — the first 30 minutes matter most, and the chance drops sharply after an hour outside the socket.
What should I store the tooth in?
Cold milk is the best widely available option. If milk is not to hand, use saline or the patient's own saliva. Never store the tooth in plain water — water destroys the living cells on the root surface that the whole chance of reattachment depends on.
Should a child's milk tooth be put back?
No. A knocked-out baby tooth should never be replanted, because doing so risks damaging the developing permanent tooth bud underneath. Still see a dentist so the injury and remaining teeth can be checked.
