If every sip of cold water or a bite of ice cream sends a sharp pain through your teeth, you’re not alone. Tooth sensitivity is common and usually means dentin, the inner layer of the tooth, is exposed or more vulnerable.

Everyday habits can make it worse. Brushing too hard with a stiff brush can wear away enamel and gum tissue, exposing the sensitive root area. Frequent acidic foods and drinks – sodas, citrus juices, vinegar-heavy snacks – soften enamel and make sensitivity more likely over time.

Grinding or clenching can also cause tiny cracks and wear that lead to sensitivity. Even whitening products used too often or incorrectly may irritate teeth.

Start by switching to a soft toothbrush and a toothpaste designed for sensitivity. Use gentle pressure and avoid aggressive back-and-forth scrubbing. Rinse your mouth with water after acidic foods instead of brushing immediately on softened enamel.

If sensitivity is limited to one or two teeth, or if it worsens suddenly, see your dentist. Cavities, cracked teeth or leaking fillings need targeted treatment, not just special toothpaste.
