Turmeric, oil pulling, and strawberries can promote oral health but have limited teeth-whitening effects. Charcoal and baking soda may help remove surface stains but can erode enamel if used too often. Homemade whitening powders,

which combine natural ingredients like baking soda and charcoal, can clean teeth but don’t effectively whiten deep stains. While these natural remedies may offer mild improvements, professional treatments are the safest and most effective option for long-lasting teeth whitening.
