Gum disease is one of the most common oral health conditions in Canada — and one of the most underestimated. It affects roughly seven out of ten Canadians at some point in their lives, yet many people don’t realize they have it until significant damage has been done. Understanding the signs, causes, and treatments for gum disease is essential for protecting not just your teeth, but your overall health.
What Is Gum Disease?
Gum disease — known clinically as periodontal disease — is an infection of the tissues that surround and support your teeth. It’s caused by plaque, the sticky film of bacteria that constantly forms on your teeth. When plaque isn’t removed through regular brushing and flossing, it hardens into tartar, which can only be removed by a dental professional. The bacteria in plaque and tartar produce toxins that irritate gum tissue, leading to inflammation and eventual tissue and bone destruction.
Gingivitis vs. Periodontitis
Gum disease progresses in stages. Gingivitis is the early, reversible stage characterized by red, swollen gums that bleed easily during brushing or flossing. At this point, no permanent damage has occurred, and the condition can be fully reversed with improved oral hygiene and professional cleaning. If gingivitis is left untreated, it can advance to periodontitis — a more serious condition where gums pull away from teeth, forming pockets that become infected. In advanced periodontitis, bone and tissue are destroyed, and teeth can loosen or need to be removed.
Warning Signs to Watch For
Gum disease is often painless in its early stages, which is why many people don’t notice it. Watch for gums that bleed when you brush or floss, persistent bad breath or a bad taste in your mouth, red, swollen, or tender gums, gums that have pulled away from your teeth, loose or shifting teeth, and changes in how your teeth fit together when you bite. If you notice any of these signs, schedule a dental appointment promptly — early detection makes treatment simpler and more effective.
Who’s at Higher Risk?
While anyone can develop gum disease, certain factors increase your risk. Smoking and tobacco use are the most significant risk factors and also reduce treatment effectiveness. Diabetes makes you more susceptible to infections, including gum disease. Hormonal changes during pregnancy, puberty, and menopause can make gums more sensitive. Certain medications that reduce saliva flow, genetic predisposition, and poor nutrition also contribute to increased risk.
The Connection to Overall Health
Research increasingly shows links between gum disease and serious systemic health conditions. Periodontitis has been associated with an increased risk of heart disease, stroke, diabetes complications, respiratory infections, and adverse pregnancy outcomes. While the exact mechanisms are still being studied, the chronic inflammation caused by gum disease appears to contribute to inflammation elsewhere in the body. Treating gum disease isn’t just about saving your teeth — it’s about protecting your whole-body health.
Treatment Options
Treatment depends on the stage of disease. Gingivitis is typically resolved with professional cleaning and improved home care. For early to moderate periodontitis, scaling and root planing — a deep cleaning procedure performed under local anaesthesia — removes tartar from below the gum line and smooths root surfaces. More advanced cases may require surgical treatments including flap surgery, bone grafts, or tissue regeneration. Your dentist or periodontist will create a treatment plan tailored to the severity of your condition.
Prevention Is Everything
Preventing gum disease is straightforward — brush twice daily with fluoride toothpaste, floss once daily, and visit your dentist regularly for professional cleanings and exams. Your dental hygienist can remove tartar buildup that brushing alone can’t address and identify early signs of gum disease before you notice symptoms. If you smoke, quitting is the single most impactful thing you can do for your gum health.
