Colgate Sensitive Pro-Relief Toothpaste - 8% Arginine Formula

Colgate Sensitive Pro-Relief Toothpaste is a 75 ml sensitivity toothpaste built around Pro-Argin technology. The formula uses 8% arginine and is designed to form a protective layer over exposed dentine, where hot, cold, and sweet stimuli can trigger discomfort.

Pro-Argin Targets Sensitivity

Colgate describes Pro-Argin as a formula that blocks exposed channels in the tooth. The Canadian product page says the toothpaste is designed for instant relief and lasting protection, while its Repair and Prevent version lists arginine at 8% and calcium carbonate at 35%. The documented Repair and Prevent formula also contains sodium monofluorophosphate at 1.1%.

The product family is positioned for teeth affected by sensitivity, with the protective layer intended to reduce contact between external stimuli and dentine tubules. Colgate's international product information describes a 1-minute fingertip application for instant relief and regular brushing for lasting protection.

75 Ml Tube And Formula

The 75 ml package is the format identified for Colgate Sensitive Pro-Relief Repair and Prevent in an English-language US retailer listing. That listing gives arginine at 8%, calcium carbonate, and sodium monofluorophosphate providing 1450 ppm fluoride. The 75 ml listing identifies the tube as a fluoride toothpaste with Pro-Argin ingredients.

Those figures describe the 75 ml Repair and Prevent product, not Colgate's larger US Sensitive Complete Protection multipack. The US listing for that separate product shows two 6.0 oz tubes, 5% potassium nitrate, and 0.24% sodium fluoride, illustrating that Colgate uses different sensitivity formulas and package formats across markets.

US Shelf Context And Pricing

US shoppers encounter Colgate Sensitive Complete Protection more readily than the 75 ml Pro-Relief tube. Target lists the separate 6 oz, two-tube pack at $8.99, or $0.75 per ounce, as of 09/22/2026. Target's US listing identifies that product's 5% potassium nitrate and 0.24% sodium fluoride.

The comparison is useful but not a like-for-like price claim. The 75 ml Pro-Relief tube uses the Pro-Argin and arginine format documented above, while the US Complete Protection pack uses potassium nitrate and a different fluoride ingredient. Formula, package size, and market labeling all affect how the products should be compared.

Best Fit For Sensitive Teeth

Colgate Sensitive Pro-Relief Toothpaste fits the sensitivity-care segment through its 75 ml tube, 8% arginine, calcium carbonate, and 1450 ppm fluoride specification. Its clearest distinction from the commonly listed US Complete Protection pack is the Pro-Argin approach rather than a 5% potassium-nitrate formula.

The product is most relevant to adults looking for a fluoride toothpaste with a sensitivity-focused arginine formula. The 75 ml size is compact, while the documented 1-minute application claim gives the product a more targeted use case than a standard fluoride toothpaste. Its practical limit is market consistency: the US shelf listing cited above covers a different Colgate sensitivity product and should not be treated as the price of the 75 ml Pro-Relief tube.
