Researchers are developing a breath mint that whitens your teeth while also rebuilding your tooth enamel.

Pulp, dentin, cementum, and enamel are the primary components of human teeth. Enamel is the toughest and most durable of all the materials. It is made up of calcium phosphate crystals called hydroxyapatite.

A lozenge containing a genetically modified peptide, or chain of amino acids, as well as phosphate and calcium ions, has been developed by University of Washington researchers.

Amelogenin, a critical protein in the production of dental enamel, the crown of the tooth, is the source of the peptide. It’s also necessary for the production of cementum, which covers the tooth root’s surface.

The peptide in each lozenge is engineered to bind to broken enamel and repair it while without damaging the mouth’s soft tissue, resulting in several micrometres of new enamel on the teeth.

The lozenge’s new enamel is whiter than that created by tooth-whitening strips or gels.

It also has the following particular advantage: Traditional tooth-whitening treatments employ hydrogen peroxide, a bleaching substance that, over time, can erode tooth enamel. The lozenge, on the other hand, preserves, strengthens, and rebuilds teeth.

The lozenge has already been tested on extracted teeth from humans, pigs, and rats by the researchers. They’re getting ready to start clinical trials now.

“We have three objectives in the clinical trial,” Professor Sarikaya said. “First, demonstrate efficacy. Second, documentation. Third, benchmarking – seeing how the whitening effect compares to existing commercial treatments.”

The trials are only anticipated to last three months.
