Can tulsi and toothpaste really whiten your teeth?
Despite tulsi's chlorophyll and antimicrobial profile, there's no biochemical evidence it whitens enamel, clarified periodontist Dr Ketan Rajput. Tooth whitening requires controlled oxidising agents like carbamide peroxide-not herbal abrasives. Applying unverified home mixtures may cause enamel abrasion and dentinal sensitivity, undermining long-term oral health rather than enhancing it.
