Does apple cider vinegar help in teeth whitening?
Apple cider vinegar exhibits mild bleaching properties due to acetic acid. However, its low pH can erode dental enamel irreversibly. Surface stain removal is possible, but long-term usage poses structural risks. "Acidic nature of acetic acid may allow it to penetrate the tooth’s outer layer, which isn't good," a dental expert said. Clinically approved whitening treatments remain safest choice.
