Dental Implants and Periodontal Care: Why Healthy Gums Make Implants Last

Dental implants have transformed the way missing teeth are replaced. By anchoring a replacement tooth into the jaw itself, an implant restores not just the visible crown but the foundation beneath it. They are highly successful — but they are not maintenance-free, and their long-term success is closely tied to periodontal health. Understanding that connection is the key to making an implant last.

How implants work: osseointegration

A dental implant is a small post — usually titanium — placed into the jawbone to act as an artificial tooth root. What makes it work is a process called osseointegration: a direct structural and functional connection between living bone and the surface of the implant. Over several months the bone grows against and bonds to the implant, creating a stable foundation that can support a crown, bridge, or full-arch restoration. This is also why adequate, healthy bone is essential — and why bone grafting is sometimes needed first, as we discuss in bone loss & regeneration.

How long do implants last?

The evidence is encouraging, with the important caveat that reported figures are study averages, not promises for any individual. A widely cited 2015 systematic review (Moraschini and colleagues) reported a mean implant survival of about 94.6% over an average follow-up of roughly 13 years. A 2024 meta-analysis looking out to 20 years found survival in the range of roughly 88–92% — about four out of five implants still in function at two decades — while emphasizing the importance of long-term follow-up care.

One distinction matters here: survival (the implant is still in place and functioning) is not the same as success (stricter criteria including minimal bone loss and no infection). Success rates are generally lower than survival rates, and definitions differ between studies — which is why a single universal “implant success rate” should be treated with caution.

Implants can get gum disease too

Implants are not vulnerable to cavities, but the tissues around them can become inflamed by bacterial plaque — just like the tissues around natural teeth. The American Academy of Periodontology describes two related conditions:

• Peri-implant mucositis — inflammation of the soft tissue around an implant without bone loss. The AAP notes it can be treated and is reversible if caught early.
• Peri-implantitis — inflammation that has progressed to involve loss of the supporting bone. It is more serious and usually requires surgical treatment.

These conditions are common enough to take seriously, which is precisely why ongoing professional monitoring of implants is recommended.

Why periodontal health is central

The same bacteria and host-susceptibility factors that drive gum disease around natural teeth can drive disease around implants. Research summarized by the AAP and peer-reviewed reviews identifies a history of periodontal disease, inadequate plaque control, smoking, and diabetes as risk factors for peri-implant disease — and finds that patients with a history of periodontitis are at higher risk. The practical implications are clear:

• Active gum disease should be brought under control before — and around — implant treatment.
• Implants need the same daily care as teeth: thorough brushing and cleaning between them.
• Regular professional maintenance, including monitoring of the implant tissues, protects the investment over the long term.

The periodontist’s role

A periodontist is the specialist in the gums and supporting bone — the foundation that implants depend on — and in the placement and maintenance of implants themselves. That dual expertise is especially valuable in complex cases involving limited bone, prior gum disease, or the need for grafting. Whether you are considering an implant or maintaining one you already have, healthy gums and consistent care are what allow it to last.
