A safe and effective way to whiten teeth with nanoparticles

In the age of Instagram and Snapchat, everyone wants to have perfect pearly whites. To get a brighter smile, consumers can opt for over the counter teeth-whitening treatments or a trip to the dentist to have their teeth bleached professionally. But both types of treatments can harm teeth.
According to an article published in ACS Biomaterials Science & Engineering (“Blue-Light -Activated Nano-TiO2@PDA for Highly Effective and Nondestructive Tooth Whitening”), researchers have now developed a new, less destructive method.
Teeth can become discolored on their outer surfaces when people consume colored foods and drinks, such as coffee, tea or red wine. As a result, many people turn to non-invasive whitening treatments that bleach the teeth.
Currently, the most common bleaching agent is hydrogen peroxide, which steals electrons from the pigment molecules that cause teeth discoloration, and this process can be sped up by exposing teeth to blue light. But high concentrations of hydrogen peroxide can break down a tooth’s enamel, causing sensitivity or cell death.
So, Xiaolei Wang, Lan Liao and colleagues wanted to see if a different blue-light-activated compound could be a safer, but still effective, alternative.
The team modified titanium dioxide nanoparticles with polydopamine (nano-TiO2@PDA) so that they could be activated with blue light.
