10 Symptoms of an Abscessed Tooth
Symptom #4: Redness
Redness is one of the cardinal signs of inflammation. It is often seen in areas that are inflamed or infected. Other associated symptoms include pain, warmth, loss of function, and swelling. There can also be a fever if there is infection.
Redness occurs due to the increased blood flow to the affected area. When there is inflammation or infection at an area, the body responds by causing changes in the microcirculation through the exudation of fluid. The emigration of leukocytes also occurs. These are mechanisms that aim to remove the offending pathogen.
