(HealthDay News) -- Periodontal disease refers to a group of problems that affect the spaces between the gums and teeth. Proper and consistent oral hygiene can help prevent the disease.

The ADAM Encyclopedia says symptoms of periodontal disease may include:

  • Gums that are red and swollen.
  • Gums that bleed, even from just brushing your teeth.
  • Chronic bad breath.
  • Teeth that loosen.
  • As the disease progresses, the gums recede, which could affect the way the upper and lower teeth meet when you bite down.
