Claims that a magical home recipe can whiten teeth in 3-5 days lack scientific support, as per evidence-based analysis of Dr Yogita Parmar at Max Healthcare (New Delhi). Biology of tooth enamel and stain removal requires controlled professional interventions. Rapid DIY methods do not change enamel structure. Evidence prioritises safe, incremental whitening, hygiene over unproven shortcuts.
