Why Charcoal, Lemon, and Lime Work for Teeth Whitening
Activated charcoal, derived from coconut shells or wood, is a porous substance that binds to stains and toxins, per a 2017 Journal of Applied Oral Science study. Lemon and lime, rich in citric acid and vitamin C, act as natural bleaching agents, breaking down surface stains, according to a 2019 Dental Research Journal report. Together, they tackle discoloration from coffee, tea, or wine while promoting oral health. However, their abrasive or acidic nature requires careful use to protect enamel. This trio is affordable, natural, and effective when used correctly, making it ideal for at-home whitening.
