Is it safe for dental work?
Certainly! Smirk® Teeth Whitening Powder PAP Pro is safe for caps, implants, bridges, veneers, and bonding. It helps maintain consistent coloration by keeping natural teeth the same shade as dental work, ensuring an even, confident smile.
Will it cause tooth sensitivity?
Absolutely not. Our peroxide-free formula is gentle on teeth and gums, free from PEG, parabens, and phthalates. It features Strontium Chloride Hexahydrate, known for sensitivity relief, forming a protective barrier over nerve endings for a pain-free experience.
How fast is shipping?
We dispatch orders on average within 9 hours of purchase.
Expect 2-4 days for your package to arrive.
Whats PAP?
Phthalimido peroxy caproic acid (PAP) is a whitening agent used in oral care products. It helps to remove surface stains from teeth, resulting in a brighter and cleaner appearance. For years only hydrogen peroxide could whiten teeth. Now with PAP entering the market everything has changed.
