What Is Periodontal Disease? Signs, Care, and Prevention
Periodontal disease means infection and inflammation of the gums and the bone that hold your teeth in place. It often starts quietly, then speeds up if plaque (a sticky film of bacteria) sits along the gumline. The good news: with the right plan, you can stop it and protect your smile for the long term.
What is periodontal disease, and how is it treated?
Periodontal disease begins as gingivitis (red, bleeding gums) and can progress to periodontitis (deeper pockets and bone loss). Dentists treat it with personalized plans that may include deep cleaning (scaling and root planing), targeted rinses or antibiotics, laser therapy, surgery for advanced cases, and regular maintenance.
How gum disease develops
Plaque builds up along your gums each day. If it isn’t removed, it hardens into tartar (a crusty deposit) that irritates the gums. Gingivitis is the early stage: gums look puffy, red, and bleed when you brush or floss. If untreated, it can advance to periodontitis. In periodontitis, the gums pull away and form pockets that trap more bacteria. Over time, the supporting bone can shrink, and teeth may loosen.
In Canada, roughly one in five adults show signs of periodontitis. It’s also tied to whole-body health. Research links gum disease with conditions like diabetes and heart disease. That’s why dentists look beyond the mouth and build a plan that fits your health, habits, and daily life. For a prevention-first overview, see how to prevent periodontal disease step by step.

Common warning signs
Call your dentist if you notice any of the following:
- Gums that bleed when brushing or flossing
- Red, tender, or swollen gums
- Bad breath that doesn’t go away
- Gum recession (teeth look “longer”)
- Loose or shifting teeth
- Pain when chewing or a change in your bite

Why individualized care matters
Gum disease doesn’t look the same for everyone. Your genetics, age, home care, diet, stress, medications (many cause dry mouth), smoking, diabetes, and even family history can all change how fast it progresses—and how it responds to care. “One-size-fits-all” advice can miss what you personally need. A personalized plan targets your risks, fits your routine, and helps you stick to it.
How your dentist diagnoses gum disease
At your visit, your dental team will:
- Measure pocket depths (a tiny ruler checks the space between tooth and gum)
- Check for bleeding, swelling, and recession
- Look at X-rays to assess bone levels
- Review your medical history and medications (dry mouth can raise your risk)
These details guide a plan that treats today’s problem and helps prevent a future flare-up.
Treatments matched to your needs
1) Non-surgical care
Deep cleaning (scaling and root planing) removes hardened deposits above and below the gumline and smooths root surfaces so bacteria can’t stick as easily. You’ll likely be numb for comfort. Curious about the process? Here’s what to expect during a deep cleaning.
Targeted antimicrobials may be used with deep cleaning. Your dentist might suggest short-term antibacterial rinses or place localized antibiotics in deeper pockets.
Laser therapy can help disinfect pockets and reduce inflamed tissue. It’s not for every case, but it can be a helpful add-on for some patients.
After initial care, your dentist will recheck healing (usually in a few weeks) and decide next steps.
2) Surgical options for advanced disease
If pockets remain deep or bone loss is advanced, your periodontist may recommend surgery. Options include flap surgery (to clean deeper areas), bone grafts (to rebuild support), or gum grafts (to cover exposed roots and strengthen thin gums). Your team will explain risks, benefits, and expected healing in plain language.
3) Periodontal maintenance
Periodontal disease is a chronic condition, so maintenance matters. Many people do best with cleanings every 3–4 months instead of every six. These visits remove bacteria before they restart the cycle and allow your team to coach your home care. Your schedule will be personalized to your risk and response to treatment.
Home care that actually works
Small, steady habits protect your gums between visits. Try these:
- Brush twice daily with a soft or electric brush (go gentle along the gumline)
- Clean between teeth every day (floss, interdental brushes, or a water flosser)
- Use fluoride toothpaste; consider an antibacterial or prescription rinse if advised
- Drink water often, especially if you have dry mouth (a common medication side effect)
- Quit smoking (your dentist can suggest tools and support)
- Choose a tooth-friendly diet (more vegetables, protein, dairy; fewer sticky sugars)
Gum disease and your overall health
Inflamed gums can raise your body’s overall inflammatory load. Studies link gum disease with diabetes control, heart disease, and pregnancy complications. Treating gum disease is not just about a healthy smile—it’s about your health overall. If you have diabetes, for example, your dentist may coordinate with your physician and adjust care to support blood sugar control.
What to expect during and after treatment
Deep cleaning is usually done with local anesthesia to keep you comfortable. You may feel some tenderness for a day or two. Over-the-counter pain relief and saltwater rinses can help. As gums heal, bleeding and swelling often improve quickly. Stick with your personalized maintenance schedule to keep pockets shallow and prevent relapse.
Costs and coverage in Canada
Many private and employer plans help with periodontal treatment, but coverage varies. Preventive cleanings are often covered more than surgical procedures. Your dental office can send a pre-authorization so you know your share beforehand.
Conclusion
Periodontal disease is common, but it’s manageable. The best results come from a plan that’s designed for you—your history, your risks, and your routine. Deep cleaning, targeted therapies, and regular maintenance can restore gum health and protect your teeth for years. If you’ve noticed bleeding gums, bad breath, or gum recession, book an assessment. Early action makes treatment simpler and results stronger.
FAQ
What’s the difference between gingivitis and periodontitis?
Gingivitis is early gum inflammation. Gums look red and bleed, but bone is still intact. Periodontitis is advanced disease with deeper pockets and bone loss. The earlier you treat, the easier it is to reverse the damage.
Can periodontal disease be reversed?
Gingivitis can usually be reversed with thorough cleaning and better home care. Once bone is lost in periodontitis, it can’t fully grow back on its own, but treatment can control infection, reduce pockets, and help you keep your teeth.
Does treatment hurt?
Deep cleaning is done with local anesthetic, so you should feel pressure but not pain. Some soreness after is normal and typically improves within a couple of days. Your team will suggest simple ways to stay comfortable.
How often should I return for maintenance?
Most people with a history of periodontitis do best with cleanings every 3–4 months. Your dentist will recommend a schedule based on your pocket depths, bleeding, dry mouth, smoking status, and daily habits.
Are lasers better than traditional treatment?
Lasers can help reduce bacteria and inflamed tissue, but they’re usually an add-on—not a stand-alone cure. The foundation is still deep cleaning, home care, and maintenance tailored to your risk.
