Gum disease is the swelling or soreness of the gums around your teeth. It is caused by bacteria in plaque, a sticky, colorless film that forms on your teeth.


This is the mildest form of gum disease. The bacteria produce by-products (toxins) which irritate the gums resulting in inflammation and infection. Gums become red, swollen and bleed easily. This stage of gum disease is reversible with effective oral care at home and professional treatment with your Registered Dental Hygienist or Periodontist.

Periodontitis: This is a form of gum disease results in the inflammation, infection, and destruction of the supporting bone and attachment fibers that hold your teeth in your mouth. As the disease progresses, pockets form allowing more bacterial plaque to form below the gum line. Tooth roots are exposed and become susceptible to acids, cold temperatures, and touch.

Early Periodontitis: 

  • Inflammation and infection are present
  • There is some bone loss which results in a pocket formation
  • Gums are bleeding

Moderate Periodontitis: 

  • Continued inflammation and infection
  • More noticeable bone loss and some tooth movement
  • Bone loss extends between the roots of the teeth
  • Gums continue to bleed
  • Teeth appear to look longer

Advanced Periodontitis:

  • Bone loss and tooth mobility increases
  • Eventual loss of one or more teeth
