When the doctor should refer to the dentist, and how urgently
- Topic
Airway threats and spreading infection: emergency department. Knocked-out teeth and exposed pulp: dentist today. Decay and gum disease: within weeks.
What it is
Doctors see many dental problems in emergency, primary care and hospital wards. The decision is not only whether to refer but how fast and to whom: a dentist, an oral and maxillofacial surgeon, ENT or the emergency department. Urgency depends on the airway, the spread of infection, bleeding, trauma and suspicion of cancer. Medical patients about to start treatments that affect the mouth (head and neck radiotherapy, antiresorptives, chemotherapy, valve surgery, transplant) need a planned dental assessment beforehand.
Key facts
- Emergency: airway signs, spreading facial or neck infection with systemic illness, uncontrolled bleeding, major facial trauma.
- Same day: avulsed permanent tooth, pulp exposure, displaced teeth, severe pain with localised swelling.
- Within days: toothache without swelling, pericoronitis without spread, dry socket, broken fillings with pain.
- Within weeks: caries, bleeding gums, loose teeth without infection, denture problems.
- Suspected cancer route: oral ulcer or patch beyond three weeks, red patch, induration, numb lip, unexplained loose teeth.
Referral urgency
| Situation | Where | How fast |
|---|---|---|
| Floor-of-mouth or neck swelling, trismus, dysphagia, stridor | Emergency department, maxillofacial or ENT | Immediately |
| Avulsed permanent tooth, exposed pulp, displaced tooth | Dentist | Same day (avulsion within the hour) |
| Toothache without swelling, dry socket, mild pericoronitis | Dentist | Within days |
| Caries, gum disease, routine care | Dentist | Within weeks |
| Persistent ulcer, red or white patch, numb lip | Oral surgery or head and neck clinic | Suspected-cancer route |
In clinical practice
- Giving antibiotics and sending a patient home without arranging dental treatment leads to recurrence and spread.
- Dental pain in people with diabetes, immunosuppression or on antiresorptives deserves earlier review.
- Write the tooth, the findings and the urgency in the referral.
Next step / Initial management
- Use the urgency tiers to decide where and how fast to refer; when in doubt, refer sooner.
- Before head and neck radiotherapy, high-dose antiresorptives, chemotherapy, cardiac valve surgery or transplant: refer for a planned dental assessment.
- Give safety-net advice: return at once if swelling grows, swallowing or breathing becomes difficult, or fever appears.
