A Green Light Treatment for Whiter Teeth, Fewer Cavities | Headline Science
The first thing people notice when they meet you is your smile. To be more confident when giving wide-mouthed, eye-crinkling smiles, people want healthy, pearly white teeth. Currently consumers turn to whitening treatments that combine hydrogen peroxide-containing gels and blue light. But they can break down enamel and lead to cavities and discoloration. Now, researchers in ACS Applied Materials & Interfaces report a new hydrogel treatment that breaks apart cavity-forming biofilms and whitens teeth without damaging them.
