You invested thousands in your dental implant. It was supposed to last a lifetime. But something feels off. Here are the five warning signs that your implant may be developing peri-implantitis — and what to do about each one.

Sign 1: Bleeding Around the Implant

Healthy implants don't bleed when you brush or floss around them. If you notice bleeding from the gum tissue surrounding your implant — especially if it's persistent — this is an early warning sign of inflammation. The bacteria that cause peri-implantitis trigger an immune response that makes the tissue fragile and prone to bleeding.

What to do: See your dentist for a probing depth measurement around the implant. Early-stage inflammation (peri-implant mucositis) is reversible with professional cleaning and improved home care.

Sign 2: Swelling or Redness

The gum tissue around a healthy implant should look the same as the tissue around your natural teeth — pink and firm. Redness, puffiness, or a shiny appearance indicates active inflammation.

What to do: Don't ignore it. Swelling that doesn't resolve within a week needs professional evaluation.

Sign 3: The Implant Feels Loose

A properly integrated implant should feel completely solid — as stable as a natural tooth root. If you notice any movement, wobble, or a different sensation when biting, this may indicate bone loss around the implant.

What to do: This is urgent. Looseness typically means bone loss has already progressed. Get imaging (X-ray or CT scan) immediately to assess the extent.

Sign 4: Bad Taste or Odor

A persistent bad taste or smell from around the implant — even with good oral hygiene — can indicate bacterial infection in the pocket between the implant and the surrounding tissue.

What to do: This is a sign of active infection. Professional treatment is needed — home care alone won't resolve it.

Sign 5: Bone Loss on X-rays

This one you won't notice yourself. During routine dental check-ups, your dentist should be monitoring the bone level around your implants with periodic X-rays. If bone loss is detected — even without symptoms — intervention is warranted.

What to do: Discuss treatment options with your dentist. If they're not equipped for peri-implantitis treatment, seek a specialist.

Treatment Options

If caught early, peri-implantitis is treatable. Kainos Dental in Korea offers laser-assisted treatment using the LOKKI YAP Laser — more effective than mechanical cleaning at reaching bacteria in the microscopic surface textures of the implant. At $300–$800 per session (vs. $1,500–$3,000 in the US), treatment in Korea is a viable option even for patients who need to travel for it.
