🦷 Can You Get Cavities Under Fillings?

Yes! Even with a filling, decay can form around or beneath it if bacteria sneak in. This usually happens when:

  • Fillings wear down or crack
  • Plaque builds up around the edges
  • Oral hygiene isn’t consistent

Prevention tips:
βœ… Brush twice daily with fluoride toothpaste
βœ… Floss carefully around fillings
βœ… Limit sugary snacks
βœ… See your dentist regularly

Old fillings don’t stop new cavities β€” keeping your teeth clean is key! 😁
