Mouth injuries are extremely common in young children, especially under the age of six. Little ones are naturally prone to accidents, whether slipping on tiles or falling with a toothbrush.
As a paediatrician (and grandparent), I’ve encountered countless cases of dental trauma and soft tissue injuries. The key is staying calm and knowing when to manage at home and when to seek urgent care.
When to See a Doctor or Dentist Immediately
If your child has any of the following, seek immediate medical or dental care:
- Bleeding that doesn’t stop after 10 minutes
- A broken, loose, or missing tooth
- A large or gaping cut on the lips, face, tongue, or inside the mouth
- A tooth pushed through the lip
- A foreign object lodged in the mouth or throat (do NOT remove it)
- Difficulty breathing or swallowing
- Signs of unusual drowsiness or disorientation
- You’re simply unsure or concerned
Common Mouth Injuries in Children
1. Frenulum Tear (Bleeding, No Visible Cut)
Scenario: A ball hits your child’s mouth. There’s a lot of blood, but no visible wound.
Diagnosis: Likely a frenulum injury — the thin tissue connecting the upper lip to the gum.
What to Do:
- Apply a cold cloth
- Give paracetamol for pain
- Avoid acidic foods (e.g. orange juice, tomato-based sauces)
- Bleeding should stop within minutes
This injury looks dramatic, but usually heals on its own.
2. Bitten Lip or Cut Lip
Scenario: A fall results in your child biting or cutting their lip.
What to Do:
- Clean the area gently
- Apply a cold compress
- Use paracetamol as needed
- Seek help if:
- The cut is deep
- Teeth punctured through the lip
- The skin is gaping or torn
3. Bitten Tongue
Scenario: Your child falls and bites their tongue during impact.
What to Do:
- Rinse the mouth with clean water
- Apply pressure with sterile gauze if bleeding
- Use a cold cloth-wrapped ice cube to reduce swelling
- Avoid placing ice directly on the tongue
- Seek help if:
- Bleeding lasts longer than 15 minutes
- The bite is larger than 2 cm
- The tongue looks partially amputated
- You see a piece of tooth embedded in the tongue
4. Minor Tooth Loosening
Scenario: A fall causes gum bleeding and a slightly wobbly tooth.
What to Do:
- Offer a soft diet for 1–2 weeks
- Visit a dentist for assessment
- Manage discomfort with paracetamol
If the tooth hasn’t shifted out of place, this is usually a minor injury.
5. Tooth Pushed into Gum (Intrusion)
Scenario: A toddler falls and a tooth appears pushed upwards.
What to Do:
- Give pain relief
- Book an urgent dentist appointment
- Follow a soft food diet
This may be a baby tooth, but an X-ray is necessary to check for root damage or harm to the developing permanent tooth.
6. Knocked-Out Permanent Tooth
Scenario: A permanent tooth is completely knocked out during sports or a fall.
What to Do:
- Stay calm and reassure your child
- Pick up the tooth by the white crown, not the root
- Rinse gently in milk
- If your child allows, reinsert it into the socket
- If not, store the tooth in a cup of milk
- Go to emergency dental care immediately
Time is critical – ideally within 30 minutes.
7. Object Injury to the Soft Palate or Throat
Scenario: A toothbrush or pencil is in your child’s mouth during a fall.
What to Do:
- Do NOT attempt to inspect or remove anything
- Go to the nearest emergency centre immediately
- A deep puncture in this area can affect large vessels or cause a serious infection
This is a high-risk injury, urgent evaluation is needed.
Prevention Tips for Mouth Injuries
Help reduce the risk of future trauma by following these safety tips:
- No running with objects in the mouth (e.g. pencils, lollipops, toothbrushes)
- Use non-slip mats in bathrooms and around wet areas
- Avoid rough play near hard furniture
- Teach older children to keep a safe distance during sports
- Always wear helmets and mouth guards during cycling, contact sports, and skating
Fun fact: Athletes are 60× more likely to have dental trauma without a mouth guard. With one, the risk drops by 82–93%.
Final Thoughts
Mouth injuries can be distressing, but most are treatable with the right response. Stay calm, assess the situation, and reach out to your doctor or dentist if you’re uncertain.
Your child’s smile is worth protecting — and you’re doing an amazing job being prepared.
