The science behind Sensodyne Rapid Relief


Here at Sensodyne, it is our job to study the causes of tooth sensitivity to really understand how to get protection from it. Sensitivity can occur when the softer, inner part of the tooth called ‘dentine’ becomes exposed, revealing small holes called tubules. When you eat something, such as a cold, hot, sweet or sour food, signals rush down these tubules, triggering the nerve inside your tooth. This can result in the instant, short, sharp sensation called tooth sensitivity.

As many as 1 in 3 people suffer from sensitive teeth, but only 1 in 3 of sensitivity sufferers act on it. What’s more, 70% of sufferers say sensitivity takes the pleasure out of eating and drinking, and many may also go to great lengths to create work-arounds for the discomfort. These may include: avoiding certain types of foods or drinks, eating or drinking on one side of their mouth, covering their teeth with tongue, changing their brushing technique, and wearing a scarf over their mouth in cold weather.

But there is no need to come up with all these ways to cope, as there’s a simple solution. Sensodyne Rapid Relief gives quick and ongoing protection from sensitivity when used as directed, to help beat sensitivity fast.


The unique Sensodyne Rapid Relief formulation is designed for quick protection. Sensodyne Rapid Relief toothpaste is powered by Strontium Acetate in a unique formulation that accelerates occlusion of exposed dentine tubules.

Sensodyne Rapid Relief delivers strontium ions to the dentine surface to help build a robust and substantive protective layer.

This allows Sensodyne Rapid Relief toothpaste to provide quick and ongoing protection when used as directed to help beat sensitivity fast, and it also leaves your mouth feeling clean and fresh.
