What causes gum disease
Gum disease begins with plaque-related inflammation and can progress when deposits remain around teeth and risk factors affect healing.
The short answer
Gum disease begins with plaque-related inflammation and can progress when deposits remain around teeth and risk factors affect healing. Early gingivitis affects the gum margin, while periodontitis can damage attachment and supporting bone.
How does plaque contribute to gum disease?
Plaque is a bacterial biofilm that collects on tooth surfaces and along the gumline. If it is not removed, inflammation can make gums red, swollen, and prone to bleeding; mineralized plaque becomes calculus and requires professional removal.
What can you do to reduce your gum disease risk?
Brush twice daily with fluoride toothpaste and clean between teeth every day using a method that fits the spaces. Arrange periodontal assessment and professional cleaning when deposits, bleeding, pockets, or gum recession are present.
When should gum disease be assessed by a dentist?
Seek care for repeated bleeding, persistent bad breath, gum recession, loose teeth, pus, or changes in how teeth meet. Pain with facial swelling or fever should be assessed urgently.
What should you ask about your gum disease stage?
Ask whether you have gingivitis or periodontitis, how deep the pockets are, and whether radiographs show bone loss. Ask which cleaning, home-care changes, or periodontal treatment is appropriate for each affected area.
Frequently asked questions
Is gum disease caused by poor brushing alone?
Plaque is central, but smoking, diabetes control, medication effects, genetics, and other factors can alter risk and healing.
Can gum disease be reversed?
Early gum inflammation can improve with plaque control and professional care; established attachment or bone loss needs periodontal management.
