What can I do?

Your gums may have receded, or some tooth enamel may have worn away. When this happens, the root surfaces of your teeth become exposed.
Exposed roots are porous, like a sponge. They contain thousands of tiny channels that lead straight to the nerves of your teeth.
When hot or cold foods and liquids come in contact with the root surfaces, they may stimulate the nerves, causing you to feel pain.

Use Colgate® Sensitive toothpaste for clinically proven sensitivity relief.
Brush the sensitive areas gently twice each day with a soft-bristled toothbrush. Colgate's 360® Sensitive brush is specifically designed for this purpose.
