Treatment of Broken Teeth
Treatment depends on the depth of the fracture: enamel-only cracks require minimal intervention or simple smoothing, enamel-dentin fractures need bonded restoration within days, and fractures exposing the pulp demand immediate pulp therapy to preserve tooth vitality. 1, 2
Immediate Assessment
When evaluating a broken tooth, determine the fracture depth through clinical examination:
- Enamel-only fractures appear as superficial cracks without dentin exposure and typically cause no sensitivity 1
- Enamel-dentin fractures expose yellowish dentin and often cause temperature sensitivity 1
- Complicated crown fractures expose pink/red pulp tissue and require urgent intervention 1
- Check for tooth mobility, which may indicate root fracture requiring radiographic evaluation 1, 2
Treatment Algorithm by Fracture Type
Enamel-Only Fractures (Uncomplicated)
- Smooth sharp edges with a dental handpiece or leave untreated if already smooth 1
- No urgent dental referral needed, but monitor for signs of pulpal necrosis (discoloration, swelling, sinus tract formation) 1, 2
- Prognosis is excellent with the tooth remaining intact and functional 2
Enamel-Dentin Fractures (Uncomplicated)
- Refer to dentist within a few days—the more sensitive the tooth, the more urgent the referral 1
- Restoration options include tooth-colored composite bonding or rebonding the original tooth fragment if available 1
- The American Academy of Pediatric Dentistry recommends bonded composite or full coverage crown to bind tooth segments together and prevent crack propagation 2
- Covering exposed dentin reduces bacterial contamination risk and discomfort 1
- Monitor for pulpal necrosis during follow-up 1
Crown Fractures With Pulp Exposure (Complicated)
- Immediate dental referral is mandatory to preserve pulp vitality 1, 2
- Timeliness is critical, especially in immature permanent teeth (within 3 years of eruption) 1
- For immature teeth with open apex: pulp therapy allows continued root development 1
- For mature teeth with closed apex: root canal therapy is the treatment of choice 1, 2
- Extraction is indicated only if patient behavior precludes pulp therapy or the crack extends deep into the root 2
Root Fractures
- Obtain radiographic examination when crown mobility is present 1, 2
- Fracture location determines prognosis: apical fractures have excellent outcomes and rarely need treatment, while fractures near the crown have poor prognosis 1, 2, 3
- Extraction is indicated for root fractures near the crown with excessive mobility and aspiration risk 2
- For severe crown-root fractures, the crown fragment must be removed and the remaining fragment assessed for orthodontic extrusion or submersion 1
Immediate Symptomatic Management
- NSAIDs (ibuprofen) are first-line for pain control, with acetaminophen as an alternative 2, 3
- Apply cold compresses to reduce swelling 2
- Follow soft diet for 10 days and avoid temperature extremes with food and beverages 2
- Maintain gentle oral hygiene to prevent infection 4
Critical Pitfalls to Avoid
- Do not delay referral for pulp-exposed fractures—immediate pulp therapy within hours to days significantly improves outcomes for preserving tooth vitality 1
- Never store avulsed tooth fragments in water, as this causes osmotic lysis of root fibroblasts; use milk or saliva instead 1
- Do not assume enamel-only fractures are benign—all fractured teeth require monitoring for delayed pulpal necrosis 1, 2
- Failing to obtain radiographs when mobility is present may miss root fractures 1
Follow-Up Monitoring
- Monitor all fractured teeth for clinical signs of pulpal necrosis: crown discoloration, gingival swelling, increased mobility, sinus tract development 2, 3, 4
- Schedule follow-up examinations to assess healing and identify adverse consequences early 5
- For treated teeth, verify absence of periapical pathology on follow-up radiographs 4
