FAQ
Pain & SymptomsWhy Are My Teeth Sensitive to Cold?
Quick Answer
Tooth sensitivity to cold is usually caused by exposed dentin, enamel erosion, gum recession, or a cracked tooth. A dentist can identify the cause and recommend treatment.
Detailed Explanation
Cold sensitivity occurs when the protective enamel layer is compromised, exposing the dentin underneath. Dentin contains microscopic tubules that connect to the nerve, causing sharp pain when exposed to cold temperatures. Common causes include enamel erosion from acidic foods and drinks, gum recession exposing the root surface, teeth grinding (bruxism), cracked teeth, and recent dental procedures. Treatment depends on the cause: desensitizing toothpaste, fluoride treatments, dental bonding, gum grafting, or a night guard for bruxism. Persistent sensitivity lasting more than a few weeks warrants a dental evaluation.
