Description
Letícia Condolo and co-authors tested, in a 2026 dental study, whether glue-like coatings guard cracked teeth during bleaching while letting the bleach work. Whitening gel's active agent, hydrogen peroxide, can seep through enamel cracks toward the pulp. That seepage may cause pain and harm.
Fifty human premolars were split into five groups, from sound unbleached teeth to cracked teeth with one of two adhesive shields. Cracks were found by shining light through the teeth and measured by software. After two bleaching rounds, gel seepage into the pulp space was read by light tools. Cracked teeth without a shield let through the most gel, while sound teeth let through the least. Color change was tracked for two weeks to check that shields did not spoil the whitening.
