Noticed dark lines or spots on your back teeth? 👀🦷
Before you assume the worst or ignore it completely - here’s what you need to know.
Dark marks on back teeth can sometimes be harmless staining, but they can also be an early sign of tooth decay or wear. The best way to know for sure is to have them checked by a dentist.
Catching things early can often mean simpler treatment and help protect your natural teeth for longer ✨
