Cracked teeth: finding the cause of biting pain
A small crack can produce sharp, unpredictable pain even when the tooth looks intact. Early assessment can help clarify what can be done.
Typical signs of a cracked tooth
A sharp pain when you release your bite, sensitivity to cold or discomfort that is difficult to locate may all occur with a crack. These symptoms are not specific to cracks, so tests are needed rather than relying on sensations alone.
How are cracks assessed?
A dentist may check existing fillings, use careful biting tests and examine the tooth under light or magnification. X-rays help assess the surrounding structures, although small cracks do not always appear clearly in an image.
Does a cracked tooth need root canal treatment?
Only if the pulp has been affected in a way that requires it. Some teeth can be managed with a protective restoration. Others may need root canal treatment followed by a crown. A crack that extends deeply into a root can make preservation unlikely.
What to do while arranging an assessment
Avoid deliberately biting hard objects on the affected tooth and seek a dental review if pain persists. Sudden swelling or severe symptoms require urgent attention. For more information on the pulp itself, read our tooth pain assessment page.
