What Should You Do If Your Child Knocks Out, Chips, or Breaks a Tooth?

September 15, 2026

Children run, climb, jump, play sports, ride bicycles, and occasionally collide with things.

Unfortunately, teeth sometimes get caught in the middle.

A dental injury can happen during sports, on a playground, at home, or from a seemingly minor fall. When it does, parents may have only seconds to determine what happened and decide what to do next.

The most important first step is staying calm enough to evaluate the situation.

After that, what you should do depends heavily on whether the injured tooth is a baby tooth or a permanent tooth.

Start by Checking Your Child

Before focusing entirely on the tooth, make sure your child has not experienced a more serious injury.

A significant fall or collision can involve the head, face, jaw, or other parts of the body.

If there are signs of a serious head injury, loss of consciousness, difficulty breathing, uncontrolled bleeding, suspected jaw fracture, or another medical emergency, seek appropriate emergency medical care.

Once immediate medical concerns have been addressed, attention can turn to the dental injury.

What If a Tooth Is Chipped?

A small chip may not cause much pain, but the tooth should still be evaluated.

The severity depends on how much tooth structure was lost and whether deeper layers were exposed.

A minor enamel chip may require relatively simple treatment or monitoring. A deeper fracture can expose dentin or the pulp inside the tooth.

If you find the broken piece, save it and bring it to the dental appointment.

Do not assume a chipped tooth is harmless simply because your child says it does not hurt.

What If the Tooth Looks Cracked?

Cracks can be difficult to evaluate at home.

Your child may complain that the tooth hurts when biting or becomes sensitive to temperature. In other cases, there may be no immediate symptoms.

A pediatric dentist can evaluate the tooth and determine how deeply the damage extends.

Prompt assessment is especially important when the injury involves a permanent tooth.

What If a Baby Tooth Is Knocked Out?

A completely knocked-out primary tooth should generally not be placed back into its socket.

Attempting to reinsert a baby tooth could potentially damage the developing permanent tooth underneath it.

Contact your child's dentist for guidance and an evaluation.

The dentist can confirm that the entire tooth was lost, examine surrounding tissues, and evaluate whether other teeth were injured.

What If a Permanent Tooth Is Knocked Out?

A knocked-out permanent tooth is a time-sensitive dental emergency.

Handle the tooth carefully by the crown, which is the portion normally visible in the mouth. Avoid touching the root.

If the tooth is dirty, gently rinse it without scrubbing or removing attached tissue.

Contact a dental professional immediately for instructions and urgent care.

Keeping the tooth moist is important. Depending on the circumstances and professional guidance, an appropriate tooth-preservation solution or milk may be used if immediate reinsertion is not possible.

Do not allow the tooth to dry out.

The chance of successfully saving a knocked-out permanent tooth can decrease as time passes, making prompt professional care particularly important.

What If the Tooth Was Pushed Out of Position?

Trauma does not always knock a tooth completely out.

A tooth may be pushed backward, forward, sideways, or deeper into the socket. It can also become partially displaced.

Do not repeatedly move the tooth or attempt complicated repositioning at home.

Contact a dentist promptly.

Treatment depends on whether the tooth is primary or permanent, how far it moved, the child's age, and the condition of the surrounding tissues.

Why Can a Tooth Change Color After an Injury?

Parents sometimes notice that an injured tooth becomes darker days or weeks after an accident.

Trauma can affect the blood supply and pulp tissue inside the tooth.

A color change does not tell the entire story by itself, but it is an important reason for follow-up.

The dentist may recommend monitoring the tooth for additional signs of pulpal or root problems.

An Injured Tooth May Need Long-Term Monitoring

One of the challenging aspects of dental trauma is that complications are not always immediate.

A tooth can appear relatively normal after an accident and develop changes later.

This is especially important for permanent teeth because trauma can affect the pulp, root, and surrounding bone.

Follow-up appointments allow the dental team to monitor healing and respond if problems develop.

Protecting Teeth During Sports

Dental injuries cannot always be prevented, but appropriate protective equipment can reduce risk.

Children participating in contact or collision sports may benefit from wearing a properly fitting mouthguard.

A mouthguard can help protect the teeth and surrounding oral tissues from direct impacts.

Children should also be discouraged from chewing ice, opening packages with their teeth, or biting hard objects that could cause fractures.

Create a Plan Before an Emergency Happens

Parents usually do not expect a dental emergency until one occurs.

Knowing who to call and understanding the difference between an injured baby tooth and permanent tooth can save valuable time.

Keep your child's dental office contact information readily available. Coaches, caregivers, grandparents, and other adults who regularly supervise your child may benefit from knowing where that information is kept.

Quick Action Can Matter

A chipped, displaced, or knocked-out tooth can be frightening for both children and parents.

However, many dental injuries can be successfully managed when they receive appropriate attention.

Remember the key distinction: a knocked-out baby tooth generally should not be replanted, while a knocked-out permanent tooth requires immediate attention.

When you are unsure about the severity of an injury, contact a dental professional.

A prompt evaluation can determine how much damage occurred, provide appropriate treatment, and establish a plan for monitoring the tooth as your child continues to grow.
