What This Guide Covers and Who It Is For
This guide walks you through what to do when your child chips, cracks, loosens, or knocks out a tooth. It covers first aid, treatment options, costs, and when to see a specialist.
Dental trauma is one of the most common childhood injuries. According to the American Academy of Pediatric Dentistry, injuries to the teeth and mouth can happen at any age. [1] Toddlers fall while learning to walk. Older children collide during sports or playground activities. Teenagers take hits during contact sports.
The steps you take right after an injury matter. The right first aid can mean the difference between saving a tooth and losing it permanently. This guide is for parents, guardians, coaches, and anyone who cares for children.
You will learn how to handle injuries to both baby teeth (also called primary teeth) and permanent teeth. The approach is different for each, and knowing the difference is critical.
Types of Dental Trauma in Children
Dental trauma ranges from a small chip to a tooth that is completely knocked out of its socket. Each type of injury needs a different response.
Common Injury Types
Not all dental injuries look the same. Some are obvious, like a missing tooth. Others are hidden, like a cracked root that only shows up on an X-ray. Here are the main types of dental trauma seen in children.
A chipped or fractured tooth means part of the tooth structure has broken off. Minor chips affect only the outer enamel. More serious fractures can expose the dentin (the softer layer under the enamel) or the pulp (the nerve and blood supply inside the tooth). When the pulp is exposed, the child typically feels sharp pain and you may see a pink or red spot on the broken surface.
A luxated tooth is one that has been pushed out of position. It may be pushed sideways, deeper into the gum (intrusion), or partially out of the socket (extrusion). These injuries are common in toddlers because their bone is softer and more flexible. [1]
An avulsed tooth is one that has been completely knocked out of the socket. This is the most urgent type of dental trauma for a permanent tooth. For a baby tooth, the approach is very different.
- Enamel chip: Small piece of the outer tooth surface breaks off. Usually painless.
- Crown fracture: Larger break that may expose dentin or pulp. Often painful.
- Root fracture: Crack in the root below the gumline. May not be visible without an X-ray.
- Luxation: Tooth pushed sideways, inward, or partially out of the socket.
- Avulsion: Tooth completely knocked out of the socket.
Baby Teeth vs. Permanent Teeth: Why the Response Is Different
The most important thing to know is whether the injured tooth is a baby tooth or a permanent tooth. The treatment approach changes significantly based on this.
Baby teeth typically start falling out around age 6. If your child is under 6 and loses a front tooth to trauma, it is very likely a baby tooth. Children between ages 6 and 12 may have a mix of both baby and permanent teeth, which can make identification harder. When in doubt, a dentist can confirm with an X-ray.
A knocked-out baby tooth should not be pushed back into the socket. [1] The roots of a baby tooth sit directly above the developing permanent tooth bud. Forcing the baby tooth back in can damage or displace the permanent tooth that has not yet come in. This is a common mistake parents make in the moment.
A knocked-out permanent tooth, on the other hand, should be replanted as quickly as possible. Time is the single most important factor. The cells on the root surface start to die within minutes when the tooth is outside the mouth. [2]
What Causes Dental Injuries in Children
Falls are the number one cause of dental injuries in children under age 5. [1] Toddlers are learning to walk and run, and their coordination is still developing. Collisions with furniture, stairs, and hard floors account for most injuries in this age group.
In school-age children and teenagers, sports injuries become the leading cause. Basketball, soccer, baseball, football, hockey, and cycling are common activities associated with dental trauma. Playground accidents and roughhousing also contribute.
Children with certain dental features are at higher risk. A child whose upper front teeth stick out (called an overjet) is more likely to injure those teeth in a fall or collision. Orthodontic treatment can sometimes reduce this risk by bringing the teeth into better alignment.
A 2018 systematic review of 24 global epidemiological studies estimated the overall prevalence of traumatic dental injuries in primary teeth at approximately 22.7%, though individual studies reported rates ranging widely depending on the population studied. [4] This means dental trauma in young children is very common and parents should be prepared.
First Aid: What to Do Right After a Dental Injury
Stay calm, assess the injury, and follow these specific steps based on the type of trauma your child experienced.
If a Permanent Tooth Is Knocked Out
This is the most time-sensitive dental emergency in children. Ideally, the tooth should be back in the socket within 30 minutes. [2] Every minute counts.
Find the tooth. Pick it up by the crown (the white part you normally see). Never touch the root. The root surface has delicate cells called periodontal ligament cells that help the tooth reattach to the bone. Touching, scrubbing, or drying the root damages these cells.
If the tooth is dirty, gently rinse it with cold milk or saline solution for no more than 10 seconds. Do not use tap water for more than a brief rinse, as the chemicals in tap water can harm root cells. Do not scrub it. Do not wrap it in tissue or let it dry out.
Try to place the tooth back in the socket. Have the child bite gently on a clean cloth to hold it in place. If the child is too young, too upset, or if you are not sure the tooth is going in the right way, store the tooth in a container of cold milk. Milk closely matches the conditions the root cells need to survive. Then go to a dentist immediately. [2]
- Do: Pick up tooth by the crown only.
- Do: Rinse gently with milk or saline if dirty.
- Do: Try to replant immediately or store in cold milk.
- Do: Get to a dentist within 30 minutes.
- Do not: Touch, scrub, or dry the root.
- Do not: Store in tap water for extended time.
- Do not: Wrap in tissue or paper towel.
If a Baby Tooth Is Knocked Out
Do not try to put a baby tooth back in. [1] Replanting a baby tooth can push it into the developing permanent tooth underneath, causing damage to the tooth bud. This can lead to discoloration, malformation, or delayed eruption of the permanent tooth.
Control any bleeding by having the child bite on a clean gauze pad or cloth for 10 to 15 minutes. Apply gentle pressure. Offer a cold compress or ice wrapped in a cloth to reduce swelling.
Call your child's dentist to schedule a visit. Even though the tooth will not be replaced, the dentist needs to check for other injuries. There may be bone fragments, damage to neighboring teeth, or soft tissue wounds that need treatment.
If a Tooth Is Chipped or Cracked
Find any broken tooth fragments and store them in cold milk or water. In some cases, the dentist can bond the fragment back onto the tooth.
Rinse the child's mouth gently with warm water. Apply a cold compress to the face near the injured area to reduce swelling. If the child is in pain, an age-appropriate dose of ibuprofen or acetaminophen can help. Avoid aspirin for children.
See a dentist within 24 hours. Even a small chip can sometimes hide a deeper crack. An X-ray can reveal root fractures or damage to the pulp that is not visible from the outside. A tooth that looks fine on the surface may need treatment underneath.
If a Tooth Is Pushed Out of Position
A tooth pushed sideways, inward, or partially out of its socket needs dental attention the same day. Do not try to move the tooth back into position yourself.
If the child can close their mouth without the displaced tooth hitting another tooth, have them bite gently on a gauze pad to stabilize it. If the tooth is blocking the bite or the child cannot close their mouth, go to a dentist or emergency room immediately.
Luxation injuries in baby teeth sometimes resolve on their own as the tooth slowly returns to its original position over weeks. However, monitoring by a dentist is still necessary because the injury can affect the nerve or the permanent tooth developing below. [1]
Preventing Dental Injuries
Custom-fitted sports mouthguards are the most effective way to protect teeth during contact sports. Research consistently supports their use. A 2009 systematic review by Benson and colleagues, which examined studies across multiple sports, found that the risk of an orofacial injury was 1.6 to 1.9 times greater when a mouthguard was not worn. [5] An earlier comprehensive review by Knapik and colleagues also concluded that mouthguards are effective at reducing dental injuries, though the exact degree of protection varies by sport, mouthguard type, and study design. [3]
Mouthguards from a dentist are molded to your child's teeth for a secure fit. Over-the-counter boil-and-bite mouthguards offer some protection but typically fit less precisely. Any mouthguard is better than none. [2]
For toddlers, childproofing the home helps reduce fall-related injuries. Padding sharp furniture corners, using safety gates near stairs, and supervising playtime on hard surfaces all lower the risk. Children with protruding front teeth may benefit from early orthodontic evaluation to reduce their vulnerability to trauma.
What Happens at the Dental Visit After a Trauma
The dentist will examine the injury, take X-rays, and determine the best treatment based on which tooth is affected and how severe the damage is.
The Initial Examination
The dentist will start by asking how the injury happened, when it happened, and what symptoms the child has. This history helps determine the type and severity of the trauma.
A clinical exam involves checking the injured tooth and surrounding teeth for mobility, fractures, and changes in color. The dentist will test whether the tooth responds to temperature or tapping, which gives clues about nerve health. Gums and lips will be checked for cuts or embedded debris.
X-rays are typically taken during the first visit. They reveal root fractures, bone damage, and the position of developing permanent tooth buds beneath baby teeth. In some cases, multiple X-ray angles are needed. The dentist may take follow-up X-rays over the coming weeks and months to monitor healing.
Common Treatments for Dental Trauma
Treatment depends on the type of injury, the child's age, and whether the tooth is a baby tooth or permanent tooth. Here are the most common approaches.
For minor enamel chips, the dentist may smooth the rough edge or apply a tooth-colored composite bonding material to restore the shape. This is typically a single visit with no anesthesia needed.
For fractures that expose the pulp, treatment is more involved. In a permanent tooth, the dentist may perform a pulp cap (placing protective material over the exposed nerve) or a partial pulpotomy (removing a small portion of damaged pulp). These procedures aim to keep the nerve alive so the tooth can continue to develop normally. In a baby tooth with pulp exposure, extraction is sometimes the simplest and safest option.
For a replanted permanent tooth, the dentist will splint it to the neighboring teeth using a thin wire or composite material. The splint holds the tooth in place while the periodontal ligament reattaches to the bone. Splints typically stay in place for one to four weeks. The dentist will monitor the tooth closely for signs of complications such as infection, root resorption (the body breaking down the root), or nerve death. [2]
- Composite bonding: Repairs small chips. One visit. Tooth-colored filling material.
- Pulp cap or pulpotomy: Protects or treats an exposed nerve. Aims to keep the tooth alive.
- Splinting: Stabilizes a replanted or loosened tooth with wire or composite for one to four weeks.
- Root canal treatment: Needed if the nerve dies. Removes the pulp and seals the inside of the tooth.
- Extraction: Removal of a tooth that cannot be saved. A space maintainer may be placed for a baby tooth.
- Crown: A cap placed over a tooth with significant structural damage. Protects the remaining tooth.
Follow-Up Visits and Long-Term Monitoring
Dental trauma does not end with the first visit. Many complications develop weeks, months, or even years later.
The dentist will typically schedule follow-up visits at two weeks, one month, three months, six months, and one year after the injury. At each visit, the tooth is checked for color changes, mobility, and sensitivity. X-rays track root development in young permanent teeth and watch for signs of resorption.
A tooth that turns gray or dark yellow after trauma may have a damaged nerve. In baby teeth, this does not always require treatment. The tooth may heal on its own or simply fall out on schedule. In permanent teeth, a color change often signals that root canal treatment (also called endodontic treatment) will be needed. [2]
Parents should watch for swelling, a pimple-like bump on the gum above the injured tooth, persistent pain, or increased looseness. Any of these signs warrant a call to the dentist.
Treatment Costs for Dental Trauma in Children
Costs depend on the injury type, the treatment needed, and whether follow-up procedures are required. Costs vary by location, provider, and case complexity.
A simple composite bonding to repair a small chip may range from $100 to $400 per tooth. A pulpotomy or pulp cap typically costs between $150 and $500. Splinting a replanted tooth may range from $200 to $600. Root canal treatment on a permanent tooth can range from $500 to $1,500, depending on the tooth. A stainless steel or white crown for a baby tooth may cost $200 to $600. Extraction with a space maintainer typically runs $150 to $500 combined.
Many dental insurance plans cover emergency treatment and follow-up care for traumatic injuries. Coverage varies widely between plans. Some plans cover the emergency visit in full but limit coverage for restorative procedures like crowns. Contact your insurance provider before treatment when possible to understand your benefits.
If your child needs care from more than one specialist, costs can add up. For example, a severe injury may require treatment from a pediatric dentist, an endodontist (root canal specialist), and possibly an oral surgeon. Ask about treatment plans and expected costs at the first visit.
When to See a Pediatric Dental Specialist
A pediatric dentist has two to three years of additional training beyond dental school, focused specifically on treating children's teeth and managing dental trauma. [1]
Any child with a knocked-out permanent tooth should see a dentist immediately. If your general dentist is unavailable, go to the nearest emergency room for initial stabilization, then follow up with a dentist as soon as possible.
A pediatric dentist is particularly helpful when the injured child is very young, frightened, or has special health care needs. Pediatric dental offices are designed for children, and the staff is trained to manage anxiety and behavior during stressful visits.
You should seek specialist care if the injury involves multiple teeth, a fractured jaw, a tooth pushed deep into the gum, or heavy bleeding that does not stop with pressure. Injuries involving permanent teeth in children under 12 also benefit from specialist care because these teeth are still developing and require careful monitoring.
- Knocked-out permanent tooth: See a dentist within 30 minutes. This is the most time-sensitive dental emergency.
- Tooth pushed into the gum (intrusion): Requires specialist evaluation, especially for permanent teeth.
- Fracture exposing the nerve: Needs same-day treatment to protect the tooth's vitality.
- Multiple injured teeth or jaw pain: May indicate a fracture requiring imaging and specialist care.
- Baby tooth trauma in a child under 3: A pediatric dentist is best equipped to evaluate very young children.
- Tooth that turns dark after injury: Schedule a follow-up to check for nerve damage.
