When a child’s tooth gets knocked out, the moments right after matter more than most parents realize. The right response depends entirely on one critical detail: whether the tooth is a baby tooth or a permanent one. The two situations call for completely different actions, and taking the wrong step, even with the best intentions, can affect whether a permanent tooth can be saved.
Dr. Matthew Savage is a board-certified pediatric dentist at Main Street Pediatric Dentistry of Belmont with 20 years of experience helping families navigate dental emergencies of all kinds. Having a pediatric dentist you already know, with a complete picture of your child’s development, makes the response faster and more accurate when these moments happen.
How to Tell Which Tooth Was Knocked Out
Before taking any action, try to determine whether the tooth is a baby tooth, also called a primary tooth, or a permanent tooth. Baby teeth are smaller and typically have shorter, more tapered roots. If your child is younger than six, it is very likely a baby tooth. Between ages seven and twelve, either type could be involved depending on which teeth have already come in.
If you are not certain, that is completely normal. The right move regardless is to contact your dentist promptly. Dr. Savage can assess the situation quickly with a clinical exam and X-rays. Families who stay current with routine dental visits and first exams at our office already have baseline records on file that help us evaluate trauma cases more accurately.
What to Do If a Baby Tooth Is Knocked Out
The correct response when a baby tooth is knocked out is to leave it out and contact our office. This surprises many parents, who instinctively want to put the tooth back. Attempting to reinsert a baby tooth carries real risk to the permanent tooth developing directly beneath it in the jaw. Reinsertion can damage that developing tooth or push bacteria deeper into the tissue.
The appropriate immediate steps are straightforward. Apply gentle pressure with a clean cloth or gauze to manage any bleeding, keep your child calm, and call our office. Per guidelines from the International Association of Dental Traumatology, endorsed by the American Academy of Pediatric Dentistry in 2020, primary teeth should not be replanted following avulsion.
Dr. Savage will examine the area to confirm the tooth is fully out, check for any soft tissue injury, and assess whether a space maintainer may be needed. A space maintainer preserves the gap left by the early tooth loss so surrounding teeth do not drift before the permanent tooth is ready to come in.
Steps to Take If a Permanent Tooth Is Knocked Out
A knocked-out permanent tooth is a true dental emergency where time is the defining variable. The tooth has the best chance of successful reimplantation if it is returned to the socket within 30 minutes of the injury, with minimal time spent dry. Every additional minute outside the mouth reduces the viability of the periodontal ligament cells that allow the tooth to reattach.
Act quickly and follow these steps:
- Pick the tooth up by the crown, the white visible part. Do not touch the root.
- If the tooth is visibly dirty, rinse it gently with milk or clean water. Do not scrub.
- If your child is calm and old enough, gently try to seat the tooth back into the socket and hold it in place. Otherwise, store it in milk or a Save-A-Tooth solution to keep it moist.
- Head to our office or an emergency dental provider immediately.
Do not store the tooth in tap water, as it can damage the root cells. Milk is the preferred storage medium if reimplantation is not immediately possible. Contact our office right away so we can prepare for your arrival and see you as quickly as possible.
What Happens When You Arrive at the Office
Once you arrive, Dr. Savage will assess the tooth, the socket, and the surrounding bone with an exam and X-rays. If reimplantation is possible, the tooth will be repositioned and stabilized with a splint bonded to adjacent teeth. That splint typically remains in place for one to two weeks while the surrounding tissue begins to heal.
Follow-up care is a critical part of managing a traumatic dental injury. Dr. Savage monitors reimplanted teeth over several visits to evaluate whether the root has reattached successfully and whether any additional treatment is needed.

Frequently Asked Questions About Knocked-Out Teeth in Children
Should I try to put my child’s knocked-out baby tooth back in?
No. Baby teeth that are knocked out should not be reinserted. Attempting to do so can injure the developing permanent tooth underneath. The right step is to control any bleeding with clean gauze, keep your child calm, and contact your pediatric dentist right away for guidance and an evaluation.
What if I cannot get to the dentist within 30 minutes after a permanent tooth is knocked out?
Keep the tooth moist at all costs. Milk is the best storage option if immediate reimplantation is not possible. Even if 30 minutes has passed, it is still worth going directly to your dentist or an emergency provider. Teeth stored in milk have been successfully reimplanted after more than an hour in some cases. Getting to care quickly gives the best possible outcome.
Do all knocked-out permanent teeth survive reimplantation?
Not always, but the odds improve significantly with fast action and proper handling. The health of the periodontal ligament cells on the root surface determines how well the tooth can reattach. Dry time and physical damage to the root are the two biggest factors affecting outcome. Dr. Savage will be straightforward with you about the likelihood of success based on the condition of the tooth when you arrive.
What is a space maintainer and when does my child need one?
A space maintainer is a small dental appliance placed in the gap left by a prematurely lost baby tooth. It prevents neighboring teeth from shifting into the space before the permanent tooth is ready to come in. Whether one is recommended depends on which tooth was lost and how much development time remains. Dr. Savage will assess this during your visit and recommend one if it would benefit your child’s developing bite.
