10 Gingivitis Symptoms
Symptom #3: Redness
Redness is a characteristic sign of inflammation often seen in infection and injury. Associated symptoms are pain, swelling, loss of function, and heat. A fever may also be present if it is an infection. An area with inflammation causes changes in the microcirculation resulting in exudation of fluid and emigration of leukocytes.
The increased blood flow to the area is the cause of redness. These are the body’s natural defenses in an attempt to remove the offending pathogen and initiate repair of damaged tissues.
