Which tissue is affected?
The inflammation affects the gums, for example the margin next to a tooth. Whether the tooth's supporting tissues are also damaged must be assessed separately.

What becomes inflamed in gingivitis?
Gingivitis means inflammation of the gums. Bacterial plaque is a common trigger. The gums may look red or swollen and bleed more easily. A dental examination shows whether the tissues supporting the teeth are also affected.

The gums are inflamed
In gingivitis, inflammation affects the gums. Red, swollen or easily bleeding gum margins may be signs of it.
Plaque plays an important role
Bacteria live in soft dental plaque. If this biofilm remains at the gumline, the surrounding tissue can respond with inflammation.
Gums can recover
Removing plaque and using suitable daily cleaning methods support recovery. Hardened deposits are removed professionally.
At a glance
How does the inflammation develop?
Bacterial plaque remaining at the gumline can cause redness, swelling or bleeding. This does not necessarily cause noticeable pain.
Can the gums recover?
Plaque-induced gingivitis can subside with effective plaque control. This includes gentle daily cleaning and professional removal of hardened deposits.

Often confused
Gingivitis or periodontitis?
Gingivitis affects the gums. Periodontitis also damages the tissues that anchor a tooth. An examination is needed to tell them apart.
Quick answers
Can gingivitis occur without pain?
Yes. Gums can be inflamed without being noticeably painful. Recurring bleeding, redness or swelling should be examined.
Does every case of gingivitis become periodontitis?
No. Gum inflammation can subside. Persistent inflammation can, however, spread to the tissues supporting the teeth.
Is brushing harder the answer?
Thorough, gentle cleaning matters, including between the teeth. Suitable techniques and cleaning aids can be discussed at the practice.

For your consultation
A question to discuss with Dr. med. dent. Niusha Barahmand Pour:
Are only the gums inflamed, or are there signs that the tooth-supporting tissues are affected too?
Healthy gums and preserving teeth for the long term are foundations of treatment planning at her practice.
An appointment can help clarify what is behind irritated gums.

Build on the simple explanation with clinical terms, key distinctions and a knowledge question.
- Gingiva
- The clinical term for the gums. They form the outer boundary of the tissues supporting the teeth.
- Plaque / dental biofilm
- Soft dental deposits containing microorganisms that live together in a layer on tooth surfaces.
- Reversible
- Able to resolve: plaque-induced gingivitis can subside with effective plaque control.
Know the difference
Gingivitis affects the gums. Periodontitis also damages the tooth's supporting tissues. Bleeding alone cannot distinguish them.
