Can I use this toothpaste if I have sensitive teeth or irritated gums?

The manufacturer specifically notes that if you already have tooth sensitivity, irritated gums, very worn enamel, or ongoing dental concerns, you should use this kind of whitening toothpaste with extra attention and stop if discomfort appears. Activated charcoal toothpastes rely on gentle polishing and adsorption, but any whitening formula — even a mild one — can aggravate existing sensitivity because the brushing action and the particles involved may interact with exposed dentine tubules or inflamed gingival tissue. If you have diagnosed dentine hypersensitivity, recession, recent dental work, or active gum disease, consult your dentist before adding a whitening toothpaste to your routine. They may recommend a desensitising toothpaste for daily use and reserve this product for occasional use, or suggest an alternative approach. Always brush with a soft-bristled brush, light pressure, and for the recommended two minutes. If sensitivity increases or gums become more irritated, discontinue use and seek professional advice.
