Behind the viral glow-up is a harsh reality your enamel can’t escape. Rice flour and toothpaste already provide abrasion; adding acidic lemon juice turns the mix into a scrub that can thin enamel, roughen the surface, and make teeth more sensitive and yellower over time. Olive oil offers no real shield against that damage. What looks like whitening is often just dehydration and aggressive polishing that your teeth pay for later.

If you want a brighter smile without gambling with irreversible erosion, choose options that respect enamel. Occasional baking soda paste, oil pulling, ADA-approved whitening toothpaste, and professional treatments can safely lift stains while fluoride and a soft-bristled brush protect what you can’t replace. A naturally shaded, intact tooth is far healthier—and ultimately more beautiful—than a brittle, over-bleached one chasing a filter-level white.
