Understanding Your Teeth
Your Enamel and Sensitive Teeth
Exposure of your tooth's dentin is the cause of regular or
occasional sensitivity, which can be quite annoying. This
feeling of pain is known as "dentin hypersensitivity."
Dentin lies just below the enamel, which is the hard, outermost
surface of a tooth. Thousands of microscopic channels run through
the dentin. Once dentin is exposed, the nerves within these
channels may become susceptible to triggers such as cold food or
drinks resulting in a short, sharp nerve pain in the tooth.
Good Oral Health Begins with Understanding
This diagram can also help you understand why exposed dentin
plays such an important role in causing that sensitivity.
With Sensodyne® Toothpaste
Sensodyne® toothpaste creates a barrier to the sensation of pain
and, with regular brushing, builds long-lasting protection.
Without Sensodyne® Toothpaste
Nerves within the tooth are triggered by hot and cold stimuli
due to worn enamel or receding gums.
