Colgate Sensitive Maximum Strength Whitening Toothpaste 3 Pack provides 24/7 sensitivity protection with twice-daily brushing. This sensitive teeth toothpaste contains potassium nitrate, clinically proven to soothe the nerves in exposed dentin. With regular use, it provides long-lasting sensitivity relief and removes surface stains to help keep teeth whiter and brighter (with regular brushing vs. non-whitening toothpaste). Plus, Colgate Sensitive Whitening toothpaste helps repair weakened enamel, protect teeth from cavities and provides the freshness you trust from Colgate. At Colgate, we make products that promote healthy smiles.
