OLD SCHOOL - Brush-on whiteners and ill-fitting strips whose brightening results were so-so at best.

NOW SCHOOL - Faster than ever whiteners that leave your teeth nearly as gleaming as in-office options.

Improvements in the fit of at-home devices, as well as bleach-delivery systems that work faster, have made DIY whitening easier than ever. In fact, many dentists we spoke to admitted to using at home
options themselves – either to maintain professional results or to avoid sitting through a not so comfy in-office procedure.

“At-home whiteners have improved vastly. They offer nearly instant results with minimal impact on your wallet,” says Michael Apa, DDS, a New York City cosmetic dentist.
