The first thing to consider is that the pain caused by the extraction and the stress caused by the nervousness of the body stimulate sympathetic excitation and secretion of large amounts of catecholamines, leading to a redistribution of blood flow, causing strong constriction of the skin vessels and reduced blood perfusion, thus ensuring blood perfusion to vital organs such as the heart, brain and skeletal muscles during stress. The above symptoms, which occur as a result of inadequate blood supply to the skin and mucous membranes, do not require special treatment and can recover on their own when the patient calms down.
However, if symptoms such as fever and pus flow occur, the possibility of infection due to tooth extraction should also be considered and further hospital visits are required to check blood count and C-reactive protein, etc. If the infection is clear, prompt anti-infection treatment is required.
