Sensodyne Rapid Action is a specialized toothpaste designed to provide fast relief from tooth sensitivity. This clinically proven formula starts working from the first brush to create a protective barrier over sensitive areas while maintaining overall oral hygiene and fresh breath. This 75ml toothpaste contains potassium nitrate as its active ingredient, which helps relieve tooth sensitivity by calming the nerves inside the teeth. The product is formulated to provide quick relief while still being gentle enough for daily use. For best results, it should be used twice daily as part of a regular oral care routine. The toothpaste helps build ongoing protection against sensitivity with continued use.
