Signs You Need a Root Canal
Root canal treatment saves teeth that would otherwise need extraction. Recognising the signs early means simpler, more comfortable treatment.
Warning Signs
Severe toothache. Pain that lingers after hot/cold. Darkening of the tooth. Swelling or tenderness in nearby gums. A recurring pimple on the gum. If you recognise these, book a check-up or emergency appointment promptly.
What Root Canal Involves
Root canal treatment removes infected pulp, cleans the canals and seals the tooth. A crown is usually placed afterwards. Modern root canal is comfortable — most patients report minimal discomfort.
A Note from Dr Sarah Metias, Principal Dentist
The symptom I always ask about first is unprovoked pain — pain that starts without any trigger, particularly at night. That pattern strongly suggests pulpitis that won't resolve without intervention. In our emergency appointments at Station House, I regularly see patients who've been managing dental pain for weeks with ibuprofen, hoping it will pass. It rarely does once the nerve is involved. If you have lingering sensitivity to cold that takes more than 30 seconds to settle, please don't wait — early treatment saves the tooth and is far less complex than addressing an abscess.
