Primary Function: It is formulated to address tooth sensitivity. The key technology, often referred to as Pro-Argin, works by plugging the microscopic channels in the dentine that lead to the tooth's nerves, thus blocking pain signals.

Whitening: In addition to its primary function, this variant also has a low-abrasive formula that gently and effectively removes surface stains, helping to restore the natural whiteness of teeth.

Comprehensive Care: Like other Colgate products, it also provides general oral health benefits, including fighting cavities, strengthening enamel, and freshening breath.

Usage: For instant relief, you can apply it directly to the sensitive tooth with your fingertip and gently massage for one minute. For lasting relief, you should brush with it twice a day.
