After a dental sports injury, act quickly: find any knocked-out tooth, hold it by the crown, and put it back in its socket if it is an adult tooth and you can. If you cannot, keep it in milk or saliva and see a dentist right away. For broken, loose, or pushed-in teeth, save any pieces, control bleeding with gauze, and get a dental assessment the same day. Go to hospital for head injuries, a possible broken jaw, or trouble breathing. This guide covers first aid by injury type, what happens at the dentist, recovery, and prevention.
First, Check for Serious Injuries
Before focusing on teeth, check the athlete for signs of a more serious injury. Call 911 or go to the nearest emergency department for:
• Loss of consciousness, confusion, vomiting, or other signs of a concussion
• A possible broken jaw, such as teeth that no longer meet or difficulty opening the mouth
• Heavy bleeding that does not slow with pressure
• Swelling or bleeding that affects breathing or swallowing
A dental injury often happens alongside a blow to the head. If there is any concern about a concussion, the athlete should stop playing and be assessed.
Dental Sports Injury First Aid by Type
| Injury | What to do right away | How soon to see a dentist |
| Knocked-out adult tooth | Hold by the crown, replant if possible, or store in milk or saliva | Immediately |
| Knocked-out baby tooth | Do not replant; control bleeding | Same day |
| Tooth pushed out of place | Do not force it back; bite gently on gauze | Immediately |
| Loose tooth | Avoid chewing on it | Same day |
| Chipped or broken tooth | Save pieces, rinse, cold pack | Same day, sooner if the nerve is exposed |
| Cut lip, tongue, or gums | Rinse, apply pressure, cold pack | Same day; hospital if bleeding does not stop |
| Jaw pain or bite change | Keep the jaw still | Hospital if a fracture is suspected |
What to Do for a Knocked-Out Tooth
A knocked-out adult tooth (avulsion) is one of the most time-sensitive dental emergencies. A 2023 study summarizing International Association of Dental Traumatology guidance explains that the cells on the root are most likely to survive when the tooth is replanted within about 15 minutes, and may remain viable but compromised when the tooth is kept in milk, saliva, or saline with less than 60 minutes of dry time.
1. Find the tooth and pick it up by the crown (the white chewing part), not the root.
2. If it is dirty, rinse it briefly in milk or water for a few seconds. Do not scrub it or wrap it in tissue.
3. Replant it if you can. Gently push it back into the socket the right way round, then bite on a clean cloth or gauze to hold it.
4. If you cannot replant it, place it in milk, or keep it in the athlete’s mouth inside the cheek if they are old enough not to swallow it. Avoid storing it in water.
5. Get to a dentist immediately. Bring the tooth with you.
Never replant a baby tooth, since this can damage the adult tooth developing underneath. Bring the child to a dentist the same day.
What to Do for a Broken, Loose, or Displaced Tooth
Chipped or broken tooth
Rinse the mouth with warm water and keep any broken pieces in milk or water. A cold pack on the cheek helps with swelling. Cover a sharp edge with dental wax or sugar-free gum. If you see a pink or red spot in the centre of the break, the nerve may be exposed, so see a dentist as soon as possible.
Loose tooth
A tooth that wobbles after a hit may have a damaged root or supporting ligament. Avoid chewing on it, eat soft foods, and see a dentist the same day. Loose teeth are often stabilized with a splint bonded to neighbouring teeth.
Tooth pushed out of position
A tooth pushed inward, outward, or deeper into the gum needs prompt care. Do not try to force it back into place. Bite gently on gauze to control bleeding and see a dentist right away.
Soft tissue injuries
Cuts to the lips, tongue, cheeks, or gums can bleed heavily. Rinse gently, apply firm pressure with clean gauze for 10 to 15 minutes, and use a cold pack. Deep cuts may need stitches. Go to hospital if bleeding does not slow.
What Happens at the Dentist After a Sports Injury?
1. Assessment: the dentist examines the teeth, gums, bite, and soft tissues and asks how and when the injury happened.
2. Imaging: X-rays, and 3D CBCT imaging when needed, check for root fractures, displacement, and bone damage that is not visible.
3. Treatment: depending on the injury, this may include replanting and splinting a tooth, repositioning a displaced tooth, bonding a chipped edge, or placing a crown.
4. Root canal treatment when needed: if the nerve is damaged or exposed, root canal treatment may be recommended. Learn more about root canal therapy in Mississauga at Tomken Dental.
5. Follow-up: injured teeth are monitored over the following weeks and months, since some problems, such as nerve damage or root resorption, appear later.
At Tomken Dental, emergency care is provided by general dentists, and the team checks for hidden damage with X-rays and 3D imaging when needed, stabilizes loose teeth, and follows up to monitor healing. Learn more about emergency dentistry in Mississauga at Tomken Dental.
Treatment Options After Dental Trauma
| Injury | Common treatment |
| Small chip | Smoothing or dental bonding |
| Larger break | Filling or crown |
| Nerve exposed or damaged | Root canal treatment, often followed by a crown |
| Loose or displaced tooth | Repositioning and splinting |
| Knocked-out tooth | Replanting and splinting, usually followed by root canal treatment |
| Tooth that cannot be saved | Extraction, then replacement with an implant, bridge, or denture |
With its in-house lab, Tomken Dental can make and place some crowns in a single visit.
Recovery After a Dental Sports Injury
• Eat soft foods while teeth are tender or splinted.
• Keep the area clean by brushing gently and rinsing with warm salt water if your dentist recommends it.
• Avoid contact sports until your dentist says it is safe.
• Attend follow-up visits, even if the tooth feels fine.
• Watch for darkening of the tooth, swelling, a pimple on the gum, or increasing pain, which can signal nerve damage or infection.
When Can You Return to Sports?
It depends on the injury and treatment. A small chip may not affect play at all, while a replanted or splinted tooth usually needs time to stabilize before contact sports resume. Your dentist will advise when it is safe to return, and a properly fitted mouthguard is strongly recommended when you do.
How to Prevent Dental Sports Injuries
Wear a mouthguard
A mouthguard helps cushion blows to the face and protect teeth, lips, and jaws. Mouthguards are recommended for contact sports such as hockey, football, rugby, lacrosse, and martial arts, and for activities with a risk of falls or impacts, such as basketball, soccer, skateboarding, and cycling.
| Mouthguard type | Fit | Considerations |
| Stock (ready-made) | Loose, one size | Inexpensive; can be bulky and make breathing and talking harder |
| Boil-and-bite | Moulded at home | Better fit than stock; may thin out where bitten |
| Custom-made by a dentist | Made from an impression or scan of your teeth | Closest fit and comfort; replace as teeth grow or the guard wears |
For children and teens, mouthguards need replacing as their teeth and jaws grow. Athletes with braces should ask their dentist about a mouthguard designed to fit over brackets.
Use other protective gear
Helmets with face masks or cages, as required in many hockey and lacrosse leagues, add protection for the face and teeth.
Treat existing problems
Protruding front teeth are more likely to be injured. Orthodontic treatment may reduce this risk for some children. Learn about orthodontics in Mississauga at Tomken Dental.
Dental Trauma After Sports in Mississauga: What to Have Ready
Coaches and parents can keep a small dental first aid kit in the team bag:
• Clean gauze
• A small sealed container
• A small carton of milk or a bottle of saline
• A cold pack
• The team or family dentist’s contact details
Knowing what to do before an injury happens saves valuable minutes.
Does Insurance Cover Dental Sports Injuries?
Coverage depends on your plan. Many dental plans cover emergency exams, X-rays, and some treatment for injured teeth, while crowns or implants may fall under major services with lower coverage. Some school or league sports insurance may also apply. Tomken Dental offers direct billing with many insurers and accepts patients covered by the Canadian Dental Care Plan. You will see and approve an estimate before treatment begins.
Dental Injuries in Children and Teens
Children and teens are especially prone to dental injuries in sports and play. Front teeth that stick out are more likely to be hit. Parents and coaches can help by making mouthguards part of the standard kit, replacing them as children grow, and knowing what to do before an injury happens. Remember that baby teeth are not replanted, while adult teeth should be replanted or stored in milk right away. Learn about family and children’s dental services in Mississauga at Tomken Dental.
Common Mistakes After a Dental Injury
• Scrubbing a knocked-out tooth or touching the root
• Storing a tooth in water or letting it dry out
• Replanting a baby tooth
• Waiting to see whether a loose or chipped tooth settles on its own
• Returning to play without checking for a concussion
Long-Term Monitoring After Dental Trauma
Some effects of a dental injury show up weeks or months later. A tooth may darken, become sensitive, develop an abscess, or show root changes on X-rays. Follow-up visits allow your dentist to catch these early and treat them before they cause pain. Keep all scheduled follow-ups, even if the tooth feels normal.
Talking to Your Child’s Coach or School
Let coaches and school staff know which dentist to contact in an emergency, and ask whether the team keeps a first aid kit with gauze and a container for a knocked-out tooth. A quick plan agreed in advance helps adults act calmly when an injury happens.
Dental Sports Injury: Quick Summary
Stay calm, check for serious injuries, save any teeth or fragments, keep knocked-out adult teeth moist in milk or saliva or replant them, and get to a dentist quickly. Follow-up visits matter even when the tooth feels fine, because some problems appear weeks or months later.

Frequently Asked Questions
How should I store a knocked-out tooth?
Replant it if possible. If not, keep it in milk or saliva and see a dentist immediately. Avoid storing it in water or letting it dry out.
Can I still see a dentist if the injury happened hours ago?
Yes. See a dentist as soon as possible. Even when time has passed, a dentist can assess the tooth and discuss options.
Should a knocked-out baby tooth be put back?
No. Replanting a baby tooth can damage the adult tooth underneath. Bring your child to a dentist the same day.
What if my tooth turns dark after an injury?
Darkening can mean the nerve has been damaged. Book a dental visit so the tooth can be checked and treated if needed.
Do I need a mouthguard for non-contact sports?
For sports with a risk of falls, collisions, or flying objects, a mouthguard is a sensible precaution. Ask your dentist which type suits your sport.
