NCT ID NCT07419685
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a toothpaste containing fluoride and baking soda could help repair early tooth decay. Thirty-one healthy adults wore a custom mouthpiece with pieces of damaged enamel for nine days. They brushed with different toothpastes and then researchers measured how much the enamel hardened and how much fluoride it absorbed.
