Getting there:

In preclinical trials, participants received a dental lozenge the size of a cough drop, with a core of calcium and phosphate coated in a layer of peptide-infused flavoring.

Not yet:

Further research is needed to investigate the permeability and chemical stability of the mineral layer to achieve an effective, easy-to-apply treatment for dentin hypersensitivity, including implementing the peptide-guided approach under in vivo conditions.
