Hypertensive Patient with Acute Pulpal Pain
A 54-year-old woman attends as an emergency with severe throbbing pain in the lower left first molar (LL6) that wakes her at night and is worse with hot drinks. The tooth has a deep occlusal restoration and is tender to percussion; there is no swelling, no trismus, and no raised floor of mouth. Her blood pressure today is 178/104 mmHg on two readings; she reports no headache, chest pain, or visual disturbance and has no known diagnosis of hypertension. She is not on any medication. She is systemically well, afebrile, and has no medical allergies. She wants the tooth 'out today'.
1. Is this a true emergency requiring immediate extraction, and how would you manage the pulpal diagnosis today?

Diagnosis: Irreversible pulpitis (spontaneous, night pain, thermal sensitivity, tender to percussion but no periapical swelling). This is a true dental emergency for pain relief, but the correct treatment is pulpal, not extraction.
Management today:
- Extraction is not indicated as first-line: the tooth is restorable and the patient is systemically well. Removing a restorable molar on the day of an emergency visit is rarely justified and removes future options.
- Offer pulpectomy (partial or full) or pulpotomy under local anaesthesia to remove the inflamed pulp and relieve pain. If she declines or access is impossible, extirpation of the coronal pulp and a temporary dressing is acceptable.
- Analgesia: paracetamol and/or ibuprofen (she has no contraindication) - avoid aspirin as an analgesic.
- Antibiotics are not indicated - there is no spreading infection, no swelling, no systemic involvement.
- Consent and document the diagnosis and the treatment offered.
2. How does the raised blood pressure alter your plan, and what would you do about it?

Interpretation: 178/104 mmHg is stage 2 hypertension and is newly detected. It is not a hypertensive emergency (no end-organ symptoms - no headache, chest pain, visual disturbance), so it does not absolutely contraindicate urgent dental treatment.
Plan:
- Do not dismiss it. Recheck after a period of rest, in a calm environment, with an appropriately sized cuff; anxiety and pain can elevate readings.
- Treat the pain - untreated pain drives BP up. Use effective local anaesthesia (aspirate; avoid adrenaline-containing solutions only if there is a specific concern, but standard 2% lidocaine with 1:80,000 adrenaline is generally acceptable at minimal doses).
- Avoid routine elective treatment if BP remains this high; limit to urgent care.
- Refer to her GP for assessment and management of newly diagnosed hypertension - this is a significant incidental finding and should be communicated in writing.
- Document the readings, the advice, and the referral.
- Recheck at follow-up; if BP is uncontrolled and elective work is planned, liaise with her GP before proceeding.
