Coffee/stain prevention concern
Multiple reviews mention daily coffee consumption as a driver; consumers purchase specifically to prevent or slow stain accumulation rather than achieve dramatic whitening.
Gentle formula reputation
Buyers chose this product because it is marketed as non-irritating whitening toothpaste; many had previous concerns about sensitivity with other whitening products.
Repeat purchase and positive experience
Several reviewers indicate they continue repurchasing after initial trials, suggesting word-of-mouth or personal satisfaction drives loyalty.
Discounted pricing
At least one buyer mentioned purchasing at a discount rather than full price, suggesting price sensitivity despite premium positioning.
