How to Keep a Dental Implant Healthy (and Avoid Peri-Implantitis)

A dental implant is one of the longest-lasting ways to replace a missing tooth — but only if the tissue around it stays healthy. The titanium post and the crown on top won't rot or decay. What can fail is the gum and bone that hold the implant in place. Understanding how that happens, and how to prevent it, is the difference between an implant that lasts decades and one that's lost in a few years.

This guide draws on specialist prosthodontic research co-authored by Dr. Sadık Taki, whose review in Acta Scientiae Dentium examined the factors that cause peri-implantitis — the leading reason healthy-looking implants run into trouble.

What is peri-implantitis?

Peri-implantitis is gum disease around an implant. It usually starts as peri-implant mucositis — reversible inflammation of the soft tissue, where the gum becomes red and bleeds when cleaned. If that's ignored, it can progress to peri-implantitis, where the inflammation reaches the bone and the bone begins to recede from around the implant. Lose enough bone and the implant loosens and eventually fails.

The mechanism is similar to the gum disease that loosens natural teeth, which is why people with a history of gum disease need to be especially vigilant after getting implants.

What causes it — and what you can control

The single biggest driver is dental plaque — the sticky bacterial film that builds up on any surface in the mouth, including an implant crown. On top of that, research into the causes of peri-implantitis consistently points to several risk factors:

• Smoking — one of the strongest and most consistent risk factors, because it impairs healing and blood flow to the gums.
• Poorly controlled diabetes — high blood sugar makes infection and tissue breakdown more likely.
• A history of gum disease (periodontitis) — the same susceptibility carries over to the tissue around implants.
• Inadequate cleaning — especially the gaps between the implant and neighbouring teeth, which a normal toothbrush can't reach.
• Leftover cement from fitting the crown, which can sit under the gum and trigger inflammation — a reason to choose an experienced clinician.
• Skipping maintenance visits, so early problems aren't spotted.

Most of these are within your control. The two that aren't fully — diabetes and a gum-disease history — can still be managed with closer monitoring.

Your daily routine for a healthy implant

Brush gently, twice a day

Use a soft-bristled brush (manual or electric) and angle it at the gumline. You're trying to disrupt plaque without scrubbing the gum away. Non-abrasive toothpaste is fine; you don't need anything special.

Clean between teeth every day

This is the step people skip — and it's the one that matters most for implants. The junction between the implant and the gum is where plaque collects and where peri-implantitis begins. Use whatever you'll actually do daily: floss, interdental brushes sized to fit the gaps, or a water flosser. Your dentist or hygienist can show you which suits your implant.

Don't smoke

If you do nothing else from this list, stopping smoking gives the biggest single boost to your implant's long-term odds.

Why professional maintenance is non-negotiable

Here's the catch with implants: early peri-implantitis is usually painless. There's no nerve in the implant to warn you, so the first sign is often bleeding or a change you might not notice yourself. That's why regular hygiene appointments matter even more than they do for natural teeth. A hygienist can clean below the gumline with implant-safe instruments, and a dentist can measure the gum pockets and check the bone level on X-rays to catch trouble while it's still reversible.

If you had your implant placed abroad, arrange ongoing maintenance with a dentist at home so someone is monitoring it long-term. Our guide on how to vet a dental clinic abroad covers asking about aftercare before you travel, and how much a dental implant costs in the UK explains what a quote should include.

Warning signs to act on

Book a check-up promptly if you notice any of these around an implant:

• Gums that bleed when you brush or floss the area
• Redness, swelling or tenderness of the gum
• A persistent bad taste or smell
• The crown feeling loose, or the gum starting to recede

Caught early, peri-implant inflammation is usually treatable with a thorough professional clean and better home care. Left late, once bone is lost, it's far harder to reverse — so early action protects the work you've paid for.

The bottom line

Implants don't decay, but they're not maintenance-free. Daily cleaning between the teeth, not smoking, and keeping up regular professional check-ups are what keep an implant healthy for the long term. The peri-implantitis review co-authored by Dr. Sadık Taki underlines a reassuring point: the biggest risks to an implant are the ones patients and their dentists can do something about.
