Tooth sensitivity is a common problem that can make everyday things—like drinking cold water or enjoying hot tea—uncomfortable. It usually happens when the protective enamel wears down or gums recede, exposing the inner layers of the tooth. These exposed areas react quickly to temperature, pressure, or sweet and acidic foods. Here are some common, real-life causes of sensitive teeth:

• Worn enamel – From hard brushing or abrasive toothpaste

• Gum recession – Exposes sensitive tooth roots

• Tooth decay – Cavities let刺激 reach the nerve

• Cracked or chipped teeth – Small breaks expose inner layers

• Teeth grinding (bruxism) – Gradually wears away enamel

• Recent dental treatments – Temporary sensitivity after procedures

• Acidic foods & drinks – Soft drinks, citrus, and energy drinks weaken enamel

• Plaque buildup – Irritates gums and increases sensitivity

• Cold air exposure – Triggers pain in exposed teeth

Simple habits can cause big discomfort—catching it early makes all the difference.
