Many adults feel self-conscious about yellowing teeth, especially after years of drinking coffee, tea, or wine. Expensive whitening treatments promise fast results, but many people continue searching for affordable and natural alternatives. One surprising remedy gaining attention is powdered eggshells, which some believe can help brighten teeth while supporting enamel health.
Eggshells are naturally rich in calcium carbonate, a mineral also found in tooth enamel. When finely ground into powder, the particles can gently polish surface stains without causing the harsh abrasion linked to some whitening products. Supporters claim the mineral content may also help strengthen enamel and reduce sensitivity over time.
