Sensodyne

Sensodyne is a brand of toothpaste designed to relieve dentin hypersensitivity, a condition characterized by pain from stimuli such as cold, heat, or sweetness. The brand is produced by Haleon, a consumer health company formed in 2022 from the former consumer health operations of GlaxoSmithKline (GSK), and marketed in many regions worldwide.

Most Sensodyne formulations contain a desensitizing ingredient, commonly potassium nitrate, intended to reduce nerve excitability in dentinal tubules. Some variants employ tubule-occluding or remineralization technologies, including calcium-based minerals and fluoride for cavity protection.

Variants include Sensodyne Pronamel, marketed for enamel protection against acid erosion, and Sensodyne Repair & Protect, which uses NovaMin (calcium sodium phosphosilicate) to promote remineralization and form a protective layer on exposed dentin.

Usage guidelines typically recommend brushing twice daily with a pea-sized amount and avoiding rinsing immediately after brushing to maintain the desensitizing agents at the tooth surface. It is intended as part of regular oral care and is not a substitute for professional dental advice.

Availability and regulation vary by country, but Sensodyne products are commonly sold over the counter in pharmacies and supermarkets and regulated as consumer oral-care products within applicable health authorities.
