Dental implants have an excellent long-term track record — but they are not maintenance-free. The tissues around implants can develop inflammation, just like gums around natural teeth. A landmark 2025 systematic review pulled together 102 clinical studies to answer a simple question: how often does this actually happen, and who is most at risk? Here is what it found, in plain language.
The Two Conditions to Know
Researchers divide implant problems into two stages:
- Peri-implant mucositis — inflammation of the gum around the implant, with bleeding but no bone loss. Think of it as the implant version of gingivitis. It is reversible with professional cleaning and better home care.
- Peri-implantitis — the same inflammation plus progressive loss of the bone holding the implant. This is the implant version of periodontitis (gum disease), and it needs professional treatment.
Catching mucositis early is the whole game, because it is the only stage you can fully reverse.
How Common Are They?
The review — led by researchers at Harvard, Tufts, and the University of Pennsylvania for the Academy of Osseointegration and the American Academy of Periodontology — analyzed data from 13,030 patients across 102 studies:
- Peri-implant mucositis: about 46% of implant patients (nearly half).
- Peri-implantitis: about 21% of implant patients (roughly 1 in 5).
Over 20 years of implant function, the cumulative incidence reached about 53% for mucositis and 22% for peri-implantitis. Those numbers sound high, but remember: mucositis is common, reversible, and largely a signal to step up cleanings — not a verdict on your implants.
Who Is Most at Risk?
The analysis identified the strongest risk indicators:
- A history of gum disease (periodontitis) — the single most consistent risk factor for both conditions. Patients who lost teeth to gum disease carry that susceptibility to their implants.
- Smoking — significantly raised the risk of both mucositis and peri-implantitis.
- Diabetes — a significant risk indicator for peri-implantitis specifically.
- Obesity — linked to higher mucositis risk.
- Alcohol consumption — linked to higher peri-implantitis risk.
What This Means for Your Implants
Three practical takeaways:
- Maintenance visits are not optional. Implants need professional cleanings and yearly checks just like natural teeth — arguably more so if you have a history of gum disease.
- Bleeding around an implant is a warning, not a quirk. Bleeding when you brush around an implant can signal mucositis — the reversible stage. Don’t wait for pain; implants rarely hurt until damage is advanced.
- Your overall health matters. Controlling diabetes, quitting smoking, and treating any remaining gum disease directly protect your implant investment.
The Specialist Advantage
A prosthodontist plans implant placement with long-term tissue health in mind — implant position, spacing, and the shape of the final crown all affect how cleanable the implant is years later. Research consistently shows that implants placed in poor positions are harder to maintain and more prone to disease. Getting the planning right from day one is the best prevention there is.

Frequently Asked Questions
What is peri-implantitis in simple terms?
It is an infection-like inflammation around a dental implant that destroys the supporting bone — the implant equivalent of advanced gum disease. The earlier stage, peri-implant mucositis (bleeding, no bone loss), is reversible.
How common is peri-implantitis?
A 2025 review of 102 studies found about 21% of implant patients develop peri-implantitis and 46% develop the milder, reversible mucositis.
Can peri-implantitis be prevented?
Risk drops sharply with regular professional maintenance, good daily cleaning, treating gum disease, controlling diabetes, and not smoking. Proper implant positioning at placement also matters.
Does bleeding around my implant mean I have peri-implantitis?
Not necessarily — bleeding usually signals mucositis, the reversible early stage. But it always deserves a professional check, because only an exam and X-ray can confirm whether bone loss has started.
I lost my teeth to gum disease. Can I still get implants?
Yes, but your history of periodontitis makes maintenance even more important. A prosthodontist will factor this into your plan and your long-term care schedule.
