How does Sensodyne Pronamel Gentle Whitening Toothpaste work?

Teddy asks…I just bought a tube of this toothpaste “Sensodyne Pronamel Alpine Breeze.” Can you tell me why it’s good for sensitive teeth?   The Beauty Brains respond: The important question isn’t how it works, it’s why in the heck they’d name a toothpaste flavor after an antiperspirant!  Oh well, it’s nice when the scent of your breath matches the smell of your armpits. But we digress… How does toothpaste for sensitive teeth work? Teeth become sensitive when their protective layers of enamel and cementum are work away.  The layer beneath the enamel, called the dentin, contains microscopic pores which expose the nerves to hot and cold materials. Then – ouch! Sensitive teeth products desensitize the tooth by blocking the nerve sensations. There are two types of nerve blocking types that are commonly used: potassium nitrate and strontium chloride. Sensodyne uses potassium nitrate at 5%.
