Why tooth injuries matter in youth sports
Tooth injuries are a common occurrence in children who play contact sports like football, hockey, basketball, and soccer, as well as in activities with fall risk like skateboarding and gymnastics. A blow to the mouth can damage a tooth in different ways—and how quickly you respond affects whether your child’s smile can be saved or restored.
This guide walks you through the main types of sports-related tooth injuries and points you to the specific care steps your child may need. It is not a replacement for urgent dental care; if your child has suffered a significant blow to the mouth, contact your dentist or an urgent-care center right away.
Types of sports tooth injuries
Chipped or broken tooth
A chip or crack in a tooth is often the most common sports injury. The tooth may feel sharp or rough, and your child may have visible damage. Even a small chip can expose deeper layers of the tooth and cause sensitivity or risk infection over time.
What to do next: See the detailed guide on chipped tooth care for step-by-step first aid and when to schedule a dental visit. Most chipped teeth need professional evaluation within 24 hours.
Loosened tooth
A blow to a tooth can cause it to loosen within its socket without falling out completely. Your child may notice the tooth feeling wiggly, painful when chewing, or uncomfortable when touched. A loose tooth can be a baby tooth or a permanent tooth, and the injury may affect the root or blood supply.
What to do next: See the guide on loosened or knocked-loose teeth for assessment and first-aid guidance. Call your dentist the same day—do not wait.
Completely knocked-out tooth
If a tooth is knocked completely out of the socket, time is critical. How you handle the first few minutes can make a significant difference in whether the tooth can be saved.
What to do next: Consult the knocked-out tooth emergency guide immediately for specific steps on handling the tooth, controlling bleeding, and deciding whether to seek emergency or urgent dental care. This type of injury requires prompt professional evaluation.
Why see a dentist even if the tooth “looks okay”
Not all damage is visible to the naked eye. A tooth that appears fine after an impact may have:
- A crack that runs deep into the tooth or root
- Nerve damage that causes the tooth to darken over time
- Injury to the tooth’s root or the bone holding it in place
- Damage to a baby tooth that affects the permanent tooth developing underneath
X-rays and a clinical exam are the only way to know for sure. If your child complains of lingering pain, sensitivity to temperature, or discoloration after any impact to the mouth, schedule a dental visit promptly.
Prevention: the best defense
While injuries happen, a well-fitted mouthguard significantly reduces the risk of tooth damage during sports. See the sports mouthguard guide to learn about custom-fitted and over-the-counter options appropriate for your child’s age and activity.

Frequently asked questions
Can a knocked-out baby tooth grow back?
Baby teeth do not regrow if they are completely knocked out. However, a new permanent tooth will eventually erupt in its place. A dentist should evaluate your child as soon as possible to rule out any injury to the underlying permanent tooth bud.
Should my child wear a mouthguard during sports?
Yes. A properly fitted mouthguard is one of the most effective ways to prevent tooth injuries during contact and collision sports. Talk to your dentist about custom or over-the-counter options that fit your child's age and sport.
What if my child complains of tooth pain after a fall but the tooth looks fine?
Internal damage is not always visible. Schedule a dental visit promptly so your dentist can examine the tooth and take X-rays to check for cracks, nerve damage, or other injuries beneath the surface.
