What Causes Sensitive Teeth?
When tooth enamel wears away or gums recession occurs —either can expose the soft, inner part of your tooth called dentin. This dentin houses thousands of microscopic channels that run toward the center of the tooth, where the nerves live.
Certain triggers like cold drinks or hot tea can travel through these channels and stimulate the nerve, causing a short, sharp pain.
