A child's dental emergency can happen in an instant — a fall, a collision during sports, or sudden severe tooth pain. Most parents are not sure whether to call a dentist, go to the ER, or handle it at home. The answer depends on the specific situation.
This guide breaks down the most common pediatric dental emergencies and exactly what to do, based on pediatric dental trauma protocols and AAP guidelines.
- Facial swelling that is spreading to the neck or throat
- Difficulty breathing or swallowing due to swelling
- A dental injury combined with a head injury or loss of consciousness
- Uncontrolled bleeding from the mouth that will not stop after 15 minutes of pressure
- Facial swelling with fever — possible spreading dental infection
- Jaw fracture or severe facial trauma
The Most Time-Sensitive Emergency: Knocked Out Permanent Tooth
A knocked-out permanent tooth is the one dental emergency where every minute matters. According to dental trauma guidelines, a permanent tooth that has been completely knocked out can often be saved — but only if treated within 30 to 60 minutes.
The clock starts the moment the tooth comes out. After 60 minutes, the chances of successful reimplantation drop significantly.
🦷 What to Do When a Permanent Tooth Is Knocked Out
Pick it up by the white part (the crown). Never touch the root — the root contains cells needed for reimplantation.
Hold it under clean water for 10 seconds only. Do not scrub, dry, or wrap it in tissue.
If your child is old enough and cooperative, gently place the tooth back in the socket. Have them bite on a cloth to hold it. Do not force it.
Place the tooth in cold milk, or between your child's cheek and gum. Do not store it in water or tissue.
Bring the tooth with you. Call ahead if possible.
If a baby tooth (primary tooth) is knocked out, do NOT try to put it back in. Reimplanting a baby tooth can damage the permanent tooth developing underneath. See a pediatric dentist within 24 hours, but it is not a 60-minute emergency.
Common Dental Situations — What to Do
Facial Swelling With Fever
Swelling of the face or jaw combined with fever can indicate a dental abscess that is spreading. This can become life-threatening if the infection spreads to the airway or bloodstream. The fact that your child can still swallow or eat does not lower the urgency.
→ Go to the nearest Pediatric ER tonight. Do not wait for a dental appointment.
Permanent Tooth Knocked Out or Broken
Any permanent tooth that is completely knocked out or broken needs to be seen within 60 minutes if possible, or same day at minimum. A broken permanent tooth that exposes the inner pink layer (pulp) is also urgent.
→ Call an emergency pediatric dentist immediately. If none is available — go to the ER.
Tooth Pushed Into the Gum (Intruded)
Sometimes a tooth is not knocked out but pushed up into the gum from impact. This looks like the tooth has gotten shorter or disappeared. This needs same-day dental evaluation.
→ Call an emergency pediatric dentist. Do not try to pull the tooth down.
Severe Toothache
A toothache that is severe, keeps your child awake at night, or is getting worse needs dental evaluation within 24 hours. This may indicate a cavity that has reached the nerve, or an abscess forming. Watch for facial swelling — if it develops, escalate to ER.
→ Call your pediatric dentist first thing in the morning. If swelling develops — go to the ER.
Chipped Baby Tooth With No Pain
A small chip on a baby tooth with no pain, bleeding, or swelling is generally not an emergency. The sharp edge can be smoothed by a dentist, but it does not need same-day care.
→ Call your pediatric dentist within a few days to schedule a non-urgent appointment.
Facial Swelling — Never Ignore It
Facial swelling from a dental infection is one of the most under-recognized pediatric emergencies. Parents often assume swelling is just from the tooth and will go away on its own. But a dental abscess can spread rapidly — to the neck, the airway, and in rare cases to the brain.
- Swollen cheek or jaw combined with fever
- Swelling that is spreading — getting larger over hours
- Swelling near the eye
- Difficulty opening the mouth fully
- Difficulty swallowing — even if your child says they can swallow fine
