Knocked out tooth first aid — dental trauma steps for adults and children

Key facts

• Hold a knocked-out tooth by the crown, not the root
• Replant or store in milk — don’t let it dry
• See a dentist within 30–60 minutes if possible
• Never replant a baby tooth
• Head injury or uncontrolled bleeding needs emergency care

First check for serious injuries

Before focusing on the tooth, check the person. If there was a blow to the head with loss of consciousness, confusion, vomiting, severe headache, a suspected jaw fracture, difficulty breathing or bleeding that does not stop with firm pressure, go to a hospital emergency department or call 998. Once serious injury is ruled out, look for the tooth and any broken pieces. Control bleeding from the mouth by biting on a clean folded gauze or cloth. Note whether the injured tooth is a baby tooth or a adult tooth, because first aid is different. Children usually lose front baby teeth around six to seven years old.

Knocked-out adult tooth: step by step

Find the tooth and hold it by the crown — the white part — not the root. If it is dirty, rinse it briefly (around ten seconds) in milk, saline or cold water; do not scrub it, use soap or wrap it in tissue. If possible, gently push it back into the socket the right way round and bite on a cloth to hold it. If that is not possible, keep it moist: milk is a good option, or the person’s own saliva in a clean container, or inside the cheek for an adult who will not swallow it. Do not let it dry out. See a dentist immediately; the sooner it is replanted, the better the chances.

Baby teeth, loosened and pushed teeth

Do not put a knocked-out baby tooth back in, as this can damage the developing adult tooth underneath; bring the child to a dentist to check for other injuries. Loosened teeth — including the common search ‘loose teeth after a blow in children’ — should be seen the same day; the dentist checks the position and may splint the tooth. Teeth pushed out of position, pushed up into the gum or pushed backwards also need prompt assessment; do not try to force them back yourself unless instructed. A tooth that is slightly sore or wobbly but not displaced still benefits from an examination and X-ray, because nerve damage can appear later.

Can a dentist put a tooth back in?

Yes — in many cases a dentist can reposition or replant a knocked-out or displaced adult tooth and hold it in place with a flexible splint bonded to the neighbouring teeth, usually for around two weeks, and sometimes longer for certain injuries. This is what people often mean when they ask whether a dentist can ‘glue a tooth back in’. A broken piece of tooth can sometimes be bonded back if it is kept in water or milk. Replanted teeth often need root canal treatment later and regular X-ray reviews, because the nerve and root may be affected. The outcome depends on how long the tooth was out and how it was stored.

Treatment and follow-up at Manhal

At Manhal, Dr. Manhal Helfawee or Dr. Fariba Alnoory examines the injury, takes X-rays, repositions or replants teeth where appropriate, places a splint, repairs fractured teeth and gives instructions on soft diet, cleaning and pain relief. Your tetanus status may need checking if the injury was contaminated with soil. Follow-up visits over the following weeks and months check healing, the colour of the tooth and the nerve; root canal treatment is started if needed. If a tooth cannot be saved, options such as implants or bridges can be discussed later. A mouthguard for contact sports helps prevent future injuries.

Dental emergencies need quick relief and a clear diagnosis. We prioritise severe pain, swelling, trauma and broken restorations, and will tell you what to do while you travel to the clinic.
