Management of Tooth Avulsion in a 6-Year-Old Child
Do not replant the tooth—an avulsed primary tooth should never be reimplanted to avoid damage to the developing permanent tooth underneath. 1
Immediate Assessment
At age 6, you must first determine whether this is a primary (baby) tooth or permanent tooth. The maxillary central incisors typically exfoliate between 5-7 years of age, so at 6 years old, this could be either dentition 1. This distinction is absolutely critical because management differs completely:
If Primary Tooth (Most Likely at Age 6):
- No replantation indicated 1
- Confirm the tooth was actually avulsed (not intruded) through clinical and radiographic examination if the tooth was found 1
- If the tooth cannot be located, obtain a radiograph to rule out intrusion rather than avulsion 1
- Consider chest radiograph only if the child displays breathing difficulties to ensure the tooth was not aspirated 1
If Permanent Tooth (Less Likely but Possible):
This would be a dental emergency requiring immediate action:
- Handle only by the crown, never touch the root 1
- Replant immediately at the scene if possible (have child bite on cloth to hold position) 1
- If immediate replantation not feasible, place in proper storage medium in order of preference: Hank's Balanced Salt Solution, cold milk, saline, or saliva (have patient drool into container) 1, 2
- Never store in water (causes osmotic lysis of root fibroblasts) 1
- Seek immediate dental care for splinting (2 weeks) and root canal therapy (within 7-10 days) 1
Post-Avulsion Management for Primary Tooth
Since this is most likely a primary tooth at age 6:
Immediate care:
- Ensure hemostasis at the avulsion site
- Check that the child can bite teeth together properly 1
- Soft diet for 1 week 1
- Monitor for signs of infection
Dental referral timing:
- Non-urgent referral to dentist for follow-up evaluation
- Immediate referral only if unable to achieve proper bite closure or if extensive gingival/facial swelling develops 1
Critical Pitfalls to Avoid
Never replant a primary tooth - This is the most important point. Replantation risks damaging the permanent tooth germ developing underneath 1
Don't assume intrusion - If the tooth cannot be found, radiographic confirmation is needed to distinguish between avulsion and intrusion 1
Consider non-accidental trauma - Child abuse should be considered in any child younger than 5 years with severe tooth injury affecting lips, gingiva, tongue, or palate 1
Antibiotics and Additional Care
- Systemic antibiotics are NOT indicated for primary tooth avulsion 1
- Antibiotics are only indicated for permanent tooth avulsion with reimplantation (penicillin for children <12 years, doxycycline for ≥12 years) 1
- Maintain good oral hygiene
- Restrict digit sucking if possible 1
Long-term Monitoring
Monitor for potential complications affecting the developing permanent tooth:
- Crown discoloration
- Gingival swelling
- Development of parulis (gum boil)
- Any signs suggesting damage to the permanent successor 1
The permanent tooth should erupt normally, though there is potential for developmental disturbances from the trauma to the primary tooth 1.
