Summary

This study tested whether a bioactive desensitizer gel can reduce tooth sensitivity better than a standard fluoride varnish. Thirty adults with sensitive teeth received one of the two treatments, and their pain levels were tracked over 6 months. The gel works by releasing calcium and phosphate to help seal exposed dentin.
