How do I recognise a cracked tooth?

A cracked tooth often causes sharp pain during specific chewing movements. Sensitivity to cold is a common early symptom. Sometimes the crack is visible as a fine line under strong lighting. Dyes or special lamps help with diagnosis. The pain comes and goes, which makes it hard to pinpoint. Left untreated, the crack can extend until the tooth fractures. X-rays do not always reveal small cracks. Early treatment with a crown or bonding prevents further damage. Avoid hard nuts or ice if you suspect a cracked tooth. A timely diagnosis often saves the tooth from extraction.
