Gum disease

Also called Gingivitis or Periodontitis

Gum disease is when your gums become swollen, sore or infected, usually because of a build-up of plaque on the teeth. Early gum disease (gingivitis) is very common and can be reversed. If not treated, it can lead to periodontitis, which damages the tissue and bone that hold teeth in place.

What it is

Brushing twice a day, cleaning between the teeth, not smoking and regular dental check-ups help prevent and treat it.

Advanced gum disease may need deep cleaning by a dentist or hygienist, and sometimes teeth are lost.

Common signs

  • Red, swollen gums
  • Bleeding when brushing or flossing
  • Bad breath
  • Gums pulling away from the teeth
  • Loose teeth

How it is usually diagnosed

  • Dental examination
  • Measuring gum pockets
  • Dental X-rays

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Dental check-up notes
  • Gum pocket charts
  • Dental X-ray reports
  • Hygienist treatment notes

Questions to ask your doctor

  • How advanced is my gum disease?
  • How often should I see the hygienist?
  • Which cleaning tools should I use?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Swelling of the face or neck, fever, or difficulty swallowing or breathing: get urgent medical help
