How to Make Your Dental Implants Last: Daily Care and Preventing Peri-Implantitis

(Part 3)

Peri-Implant Mucositis and Peri-Implantitis

Two related but distinct conditions come up constantly in implant care, and confusing them leads to either unnecessary panic or dangerous complacency.

Peri-implant health

A healthy implant shows no redness, no swelling, no bleeding when the gum is gently checked, and no ongoing bone loss. Some settling of the bone level in the months after placement is normal and expected; it is not itself a sign of disease.

Peri-implant mucositis

Mucositis is inflammation confined to the soft tissue around the implant. The hallmark sign is bleeding when the area is gently probed or cleaned, sometimes with visible redness or puffiness. Crucially, there is no progressive loss of supporting bone at this stage. Strong evidence from both laboratory and human studies points to plaque as the direct cause.

Mucositis is generally considered reversible, since no permanent bone damage has occurred and the process can, in principle, be turned around by removing the plaque driving it. In practice, complete resolution is not guaranteed to happen quickly; as the previous section described, a return to full clinical health can take longer than a few weeks of improved cleaning. This stage is nonetheless where intervention has the best chance of preventing further damage, which is why bleeding gums around an implant deserve attention rather than a shrug.

Peri-implantitis

Peri-implantitis is a step further: inflammation of the same kind, but now accompanied by progressive loss of the bone that anchors the implant. It typically shows up alongside bleeding and, in more advanced cases, pus, deepening pockets, or visible gum recession.

One of the most clinically important facts about peri-implantitis is that it frequently develops with little or no pain. Bone can be quietly lost for a long time before a patient notices anything through sensation alone, which is a central reason routine professional monitoring matters even when everything feels fine.

Among people who already had mucositis, roughly three in ten went on to develop peri-implantitis within five years in one well-documented study. That risk depended heavily on preventive maintenance: around 44% of those without regular maintenance progressed to peri-implantitis, versus about 18% of those who attended regularly. Both figures matter. Maintenance reduces the risk substantially; it does not eliminate it.

How common are these conditions?

Pooling data from more than a hundred studies and over 13,000 patients, roughly 46% of implant patients show some degree of mucositis and about 21% show peri-implantitis, measured at the patient level (at least one implant affected). Stricter, more recent diagnostic criteria tend to report somewhat higher figures for both, and prevalence generally rises the longer implants have been in function.

These are population averages, not a prediction for any individual. Risk is also not evenly distributed: among non-smokers specifically, only about 5% of implants (not patients) showed peri-implantitis in one large analysis, versus roughly 18% across implants generally.(To be continued)
