7 Warning Signs of Gum Disease You Should Never Ignore

Gum disease is deceptively quiet in its early stages. Unlike a cavity — which often announces itself with sensitivity or pain — gingivitis and early periodontitis can progress for months or years without causing significant discomfort. By the time it hurts, meaningful damage may already be done.

This is precisely why gum disease remains the most common cause of adult tooth loss in Canada, despite being almost entirely preventable with early intervention.

Here are the seven warning signs to watch for — and what to do if you notice them.

Healthy gums do not bleed. Period.

If your gums bleed when you brush or floss, even occasionally, this is almost always a sign of inflammation — the hallmark of gingivitis, which is the earliest, most reversible stage of gum disease. Many people dismiss bleeding gums as a normal response to flossing, particularly if they floss infrequently. It is not.

The good news: gingivitis is fully reversible with a professional cleaning and improved home care. It does not have to progress further.

Healthy gum tissue is pale pink, firm, and fits snugly around each tooth like a cuff. Inflamed gums are redder, often slightly swollen, and may look shiny or feel spongy to the touch.

This visual change reflects the increased blood flow and immune response happening beneath the surface as your body fights bacterial infection in the gum tissue.

Occasional bad breath is normal — typically related to food, morning dryness, or temporary digestive issues. Persistent bad breath that does not resolve with brushing, flossing, and tongue cleaning is a different matter.

The bacteria responsible for gum disease produce volatile sulfur compounds — the same compounds responsible for the characteristic odour of periodontal disease. Chronic bad breath (halitosis) despite good oral hygiene warrants a professional evaluation.

If your teeth look "longer" than they used to — if more of the root surface is visible than in the past — your gums are receding. Recession exposes the more sensitive root surface of the tooth (which lacks enamel protection), leading to temperature sensitivity and an increased cavity risk at the gum line.

Recession can result from periodontal disease, aggressive toothbrushing technique, or both. Once the gum tissue is lost, it does not regenerate on its own — though surgical procedures can restore it in certain cases.

New or worsening sensitivity — particularly to cold temperatures or sweet foods — can indicate gum recession exposing root surfaces. It can also indicate that bone loss from periodontitis is affecting the attachment around the root.

Sensitivity is worth investigating, not masking with desensitising toothpaste alone. Identifying and treating the underlying cause is always preferable to managing the symptom.

Healthy adult teeth should have no detectable movement. If a tooth feels even slightly mobile — or if your bite has changed, or your teeth no longer fit together the way they used to — this is a sign that the bone supporting your teeth has been compromised.

Bone loss from periodontitis is irreversible. The bone that is lost does not grow back. Teeth that become significantly mobile from bone loss are often not salvageable. This is why early detection matters so profoundly — catching gum disease at the gingivitis stage, before bone loss begins, keeps all your options open.

Gum disease is not typically painful in its early-to-moderate stages — which is what makes it so insidious. Pain when chewing, however, can indicate a periodontal abscess (a localised pocket of infection), significant attachment loss, or a cracked tooth — all of which require prompt attention.

Any new or unexplained pain during eating should be evaluated by a dentist as soon as possible.

Do not wait for your next scheduled appointment. Call your dental office and describe what you are experiencing. In most cases, a professional cleaning and full periodontal assessment can be scheduled quickly — and the earlier treatment begins, the better the outcome.

At Alces Dental, our periodontal assessments include full pocket depth charting, bone level evaluation from digital X-rays, and a personalised treatment plan. For patients with active gum disease, we typically recommend scaling and root planing — a deep cleaning below the gum line — followed by a more frequent maintenance interval.

Gum disease is not something to be embarrassed about. It is extraordinarily common, driven heavily by genetics and systemic factors as well as home care. But it is also something that, caught early, can be fully controlled — and your natural teeth preserved for a lifetime.
