What is a common characteristic of acute gingival inflammation?

In cases of acute gingival inflammation, a smooth, shiny surface is often observed as a common characteristic. This occurs due to the edema and fluid accumulation that result from inflammation. The gingival tissues swell and seem glossy because of the inflammatory response, which brings an increased blood supply and fluid collection in the area. This shiny appearance can be a critical diagnostic feature, indicating active inflammation and changes in gingival health.

Severe pain is also commonly associated with acute gingival inflammation; however, the perception of pain can vary from patient to patient. Pain may not always be as severe in all cases, which makes it less definitive than the characteristic of the smooth, shiny surface that arises from the inflammation process.
