A recent warning from dentist Anne Lahnalammi Ebeling highlights the rise of toothpaste containing hydroxyapatite, a substance claimed to repair enamel damage and whiten teeth, as an alternative to fluoride. Hydroxyapatite, composed of calcium and phosphate, is the primary mineral found in tooth enamel, which has raised interest in its application within toothpaste. Many such products are becoming more prevalent in pharmacies and health stores, contributing to the shifting conversation about dental care.
