The four stages of gum disease, and what each one costs to treat
Gum disease is painless for most of its course, which is why it is usually found late. Here is how it progresses, what treatment each stage needs, and where the cost rises steeply.

Most patients who come to us with loose teeth are surprised to hear they have had gum disease for years. It rarely hurts. It does not usually stop you eating. By the time it becomes obvious, a good deal of the damage is permanent.
The useful thing about gum disease is that it follows a predictable path. If you know which stage you are at, you know what treatment you need and roughly what it will cost. Here is that path, stage by stage.
Stage one: healthy gums
Worth describing first, because many people have never seen healthy gums and assume their own are normal. Healthy gums are pale pink, firm, and sit tightly against the tooth in a thin scalloped edge. They do not bleed when brushed or flossed, not even a little.
On the chart, pocket depths measure 1 to 3mm at every point. There is no bleeding on probing and no bone loss visible on X-ray.
Treatment needed: a professional clean every six months
Typical cost: from NPR 2,000 per visit
Stage two: gingivitis
Plaque sits along the gumline long enough to harden into calculus, and the gum responds with inflammation. It becomes red, slightly swollen, and bleeds when you brush. This is gingivitis and it is extremely common.
The important detail is what has not happened yet: no bone has been lost. Nothing is permanent at this point. A thorough professional clean plus a corrected home routine resolves it, usually within two weeks.
This is also the stage most people ignore, because bleeding gums do not hurt and it is easy to assume you are brushing too hard. The bleeding is the warning that arrives before the damage.
Treatment needed: scaling and polishing, plus technique correction
Typical cost: from NPR 2,000, usually one visit
Reversible: completely
Stage three: early to moderate periodontitis
If inflammation continues, it moves below the gumline. The fibres attaching gum to tooth break down, and pockets form between the two. Bacteria colonise those pockets, where no toothbrush reaches. The bone that holds the tooth starts to resorb.
On the chart, pockets now measure 4 to 6mm and bleed when probed. X-rays show the first loss of bone height. Patients often notice nothing at all, or only bad breath that keeps coming back.
Treatment moves from cleaning to deep cleaning: scaling and root planing under local anaesthetic, quadrant by quadrant, cleaning inside the pockets and smoothing the root surfaces so the gum can reattach. We re-measure six to eight weeks later and compare with the original chart.
The bone lost at this stage does not come back. Treatment stops the process; it does not rewind it. That is the first point where waiting costs you something you cannot buy back.
Treatment needed: scaling and root planing, quoted per quadrant
Usually one or two visits, plus a re-evaluation
Reversible: the inflammation, yes. The lost bone, no.
Stage four: advanced periodontitis
Pockets exceed 6mm, substantial bone has been lost, and teeth begin to loosen, drift, or splay outward. Patients notice gaps opening between front teeth, a bite that feels different, or a tooth that moves when pushed with the tongue.
Deep cleaning alone often cannot reach the base of pockets this deep. Surgical access is usually required, so the root surfaces and bone defects can be cleaned directly, and grafting may be considered in specific defects.
Some teeth at this stage cannot be saved. Where a tooth is lost, replacement becomes the next conversation: an implant, a bridge, or a denture, all considerably more expensive than the treatment that would have prevented the loss.
Treatment needed: periodontal surgery, quoted per site
Possible additional cost: extraction and replacement, from NPR 100,000 for an implant
Reversible: no. The goal is keeping the remaining teeth.
Where the cost actually escalates
The jump is not gradual. Treating gingivitis costs about the same as a routine cleaning. Treating moderate periodontitis costs several times that. Treating advanced disease, including replacing teeth you lose, costs an order of magnitude more.
This is the only real argument for early examination, and it is a financial one as much as a clinical one. A gum check costs a consultation fee. The alternative, discovered five years later, is measured in implants.
How to find out which stage you are at
Not by looking in the mirror. Pocket depth is measured with a graduated probe at six points around every tooth, and bone level is assessed on X-ray. That charting takes about twenty minutes and gives you a definite answer rather than an impression.
If your gums bleed when you brush, if your breath is persistently bad, or if you have simply never had your gums charted, that examination is the thing worth booking.
