Gum disease is the quietest serious problem in dentistry. It rarely hurts until it is advanced, and the bone it destroys around your teeth does not grow back on its own. Most people who lose teeth to it never had a symptom dramatic enough to make them call.
The one early sign that is easy to notice is also the one most often dismissed: gums that bleed when you brush or floss. That is not normal, and it is not a sign of brushing too hard. It is inflammation, and at that stage it is highly treatable.
Gingivitis and periodontitis are not the same thing
Gingivitis is inflammation of the gum tissue — red, puffy, bleeding gums — with no bone loss yet. It is reversible. Professional cleaning plus consistent home care will usually resolve it completely.
Periodontitis is what happens when that inflammation continues and the supporting bone begins to dissolve. The gum detaches from the tooth, forming pockets that trap bacteria in places no toothbrush reaches. This stage is manageable and can be stabilized, but the lost bone does not return. The distinction matters because it determines whether treatment is a cure or a control program.
How we measure it, rather than guess
Periodontal assessment is a measurement, not an impression. We probe the depth of the space between gum and tooth at multiple points around every tooth. Healthy readings are shallow; deeper readings indicate attachment loss, and the pattern across the mouth tells us whether the problem is localized or generalized.
X-rays complete the picture by showing the actual bone level. Together these give a baseline that lets us tell, at the next visit, whether what we did worked — which is the only meaningful measure of periodontal treatment.
Scaling and root planing
When pockets have formed, a standard cleaning is no longer sufficient because it cannot reach the root surfaces below the gumline. Scaling and root planing — often called a deep cleaning — removes hardened deposits from those root surfaces and smooths them so the gum tissue can reattach and the pocket can shrink.
It is typically done with local anesthetic, often across two visits by half the mouth at a time. Afterwards, maintenance visits move to a shorter interval than standard cleanings, because the pockets that remain repopulate with bacteria faster than healthy tissue does.
Receding gums and why they matter
Recession exposes root surface, which is softer than enamel, decays more easily, and is frequently sensitive to cold. It has several possible causes — periodontal disease, aggressive brushing, grinding, or simply the anatomy you were born with — and the right response depends entirely on which one applies.
Identifying the cause is the point. Treating recession from over-brushing with a deep cleaning helps nobody, and treating recession from active periodontal disease with a softer toothbrush helps even less.
The whole-body connection, stated carefully
Periodontal disease is associated with several systemic conditions, including diabetes and cardiovascular disease. The relationship with diabetes is the best established and runs in both directions: poorly controlled blood sugar worsens gum disease, and severe gum disease makes blood sugar harder to control.
It is worth being precise here rather than sweeping. Association is not the same as proof of cause for every condition on the list. What is genuinely well supported is that chronic oral infection is not isolated from the rest of your health, and that treating it is worthwhile on its own terms.
