It’s easy to feel invincible following a professional cleaning at the dentist, but it’s actually right after this thorough scouring that you’re at the highest risk of staining your teeth.
Saliva contains glycoproteins that adhere to the surface of the teeth, and this invisible layer is called the dental pellicle. The pellicle is removed (along with any stains) during professional cleanings, leaving the enamel more susceptible to stains.
This is why it’s important to avoid dark foods and drinks for two to three hours after a cleaning to give the pellicle time to reform.
