Understanding Teeth


Your Enamel and Sensitivity

Exposure of your tooth's dentin, which lies just below the enamel, is the cause of regular or occasional sensitivity, which can be quite annoying. Once dentin is exposed, the nerves within the dentin may become susceptible to triggers such as cold food or drinks resulting in a short, sharp nerve pain in the tooth.


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.
