Implant Inflammation: Causes and Prevention

Implant inflammation is the general name for an inflammatory process in the gum and bone tissue around a dental implant. Implants are a long-term and successful treatment, but, like natural teeth, the tissues around them must be kept healthy; without care and regular dental check-ups the risk of inflammation rises. The mild, reversible form of inflammation affects only the gum (peri-implant mucositis), while the more severe form leads to the loss of the bone that supports the implant (peri-implantitis). In its early stage the condition is often painless and the patient may not feel it — which is exactly why regular check-ups and hygiene are decisive. Below we explain in plain language what implant inflammation is, why it happens, its signs and, most importantly, how it can be prevented.

What is implant inflammation?

“Implant inflammation” refers to an inflammatory process in the gum and/or bone tissue around an implant. It can be compared to gum disease around natural teeth. Inflammation has two main stages: the milder form — peri-implant mucositis — is inflammation of the gum (soft tissue) only, occurring without bone loss; this stage is usually reversible with treatment. The more severe form is called peri-implantitis — here, along with the inflammation, the bone that supports the implant is gradually lost. Because lost bone does not return on its own, it is very important to detect and stop the inflammation at an early stage. You can find detailed information about peri-implantitis in our separate article.

• Peri-implant mucositis — inflammation of the gum only, with no bone loss; usually reversible with treatment.
• Peri-implantitis — inflammation along with the gradual loss of the bone that supports the implant; the more severe form.
• Lost bone does not restore itself — which is why early detection plays a key role.

Is inflammation after surgery normal?

In the first days after an implant is placed, mild swelling, redness or tenderness of the gum can be an ordinary part of the healing process and is usually temporary — this is not the same as the bacteria-driven disease process. Such an early reaction usually decreases gradually. But if the swelling and pain do not improve as the days pass and instead get worse, or if there is pus, persistent bleeding or increasing pain, this may already be a sign of inflammation that needs a dental examination. Likewise, redness, swelling and bleeding that appear months or years after the implant has fully healed are not considered normal. Only a dentist can determine, on the basis of an examination, what is normal and what is a warning sign; do not try to assess it yourself. You can read about the ordinary course of healing in our article on the implant healing time.

What are the causes of implant inflammation?

The main cause of implant inflammation is the inflammation created by bacterial plaque (biofilm) that builds up on the implant and at the gum margin — that is, insufficient hygiene is the central factor. Alongside this, some factors can increase the risk of inflammation. Only a dentist can assess how much they apply to you; we list them here as risk factors, not as a diagnosis.

• Insufficient oral hygiene and the build-up of plaque — the main factor.
• Residual prosthetic cement left under the gum (excess cement).
• Smoking — a known risk factor that affects tissue health and healing negatively.
• A past or present history of gum disease (periodontitis).
• Some general health conditions, such as uncontrolled diabetes.
• A lack of regular professional care and check-ups.

The signs of implant inflammation

The signs of inflammation are not always obvious — especially in the early stage the condition is often painless, so the patient may not feel the problem themselves. If one or more of the signs below are present, you should see a dentist; do not try to assess them yourself:

• Redness or swelling of the gum around the implant.
• Pain, tenderness or a feeling of pressure in the implant area.
• Bleeding from the gum when brushing or during examination (probing).
• Discharge of pus from the gum margin, or a persistent unpleasant taste in the mouth.
• Gum recession or the metal part of the implant starting to show.
• In the late stage, a feeling that the implant is mobile — this is a serious sign and calls for an urgent examination.

What to do if there are signs of inflammation?

First of all, do not try to treat the symptoms yourself — “hiding” the problem with antibiotics, mouth rinses or painkillers can only cost you time. The right step is to see a dentist as soon as possible. The dentist determines the stage of the inflammation on the basis of an examination and, if needed, an X-ray. The early stage (mucositis) can often be managed with professional cleaning of the implant surface and improvement of home hygiene. In more advanced cases — in peri-implantitis — surgical treatment or, in selected cases, restoration of bone may be needed; you can read a detailed description of treatment in our article on peri-implantitis. The outcome of treatment depends on the stage, general health and hygiene, and no outcome can be guaranteed in advance — which, once again, shows why early detection is important.

How can implant inflammation be prevented?

The good news is that the risk of implant inflammation can be significantly reduced, and the basis for this is daily hygiene together with regular professional care. The steps below help reduce the risk, but no measure gives a 100% guarantee — your dentist determines the programme suited to your individual risk factors:

• Daily proper hygiene: careful but gentle cleaning of the implant and the gum margin (a brush, interdental brushes or the aids your dentist recommends).
• Regular dental check-ups and professional cleaning — the most reliable way to detect inflammation early.
• Stopping or reducing smoking.
• Keeping conditions such as gum disease or diabetes under control.
• Seeing a dentist without delay at the first signs (redness, bleeding, swelling).
