When Should You See a Dentist?

Many dental conditions benefit from early assessment. As a general guide, we recommend booking an appointment if you experience:

Dental pain lasting more than 24–48 hours

Persistent pain is unlikely to resolve on its own and usually indicates an underlying problem.

Facial or jaw swelling

Swelling may suggest an infection that requires clinical evaluation.

Pain when biting or releasing bite pressure

This may indicate a crack, infection, or other structural issue with a tooth.

Sensitivity to hot or cold that lingers

Prolonged sensitivity can suggest nerve involvement or deepening decay.

A bad taste or visible swelling around a tooth

These symptoms may indicate an active infection or abscess.

Important: If you experience difficulty breathing, difficulty swallowing, or rapidly spreading facial swelling, please attend your nearest A&E or call 999 immediately.
