Tooth Sensitivity: How It Works, Explained Simply

Video Transcript

Something cold or sweet can trigger a quick, sharp twinge in a sensitive tooth. This happens when enamel wears thin or the gums pull back. That exposes the softer layer underneath, called dentin. Dentin is full of microscopic tubules that lead toward the nerve. Hot, cold, and sweet signals travel through the tubules and reach the nerve. Sensitivity toothpaste and gentle brushing can help calm the response. Protecting the enamel and gumline keeps teeth more comfortable. This video is for general education only. It is not medical or dental advice. Ask your dentist what's right for you.
