What are the symptoms of oral mucosal infection after tooth extraction?

If a mucosal infection occurs after tooth extraction, the main symptoms include: 1. Pain: Infection can cause significant pain at the affected site, possibly accompanied by neuroreflexive pain radiating to surrounding areas. 2. Oral malodor: The infection leads to excessive bacterial growth in the mouth, producing putrefactive and necrotic substances, resulting in bad breath and an abnormal odor in exhaled breath. 3. Redness and swelling: The infection irritates the oral mucosa, causing local vasodilation and increased permeability, leading to redness and swelling. This may manifest as red patches or edema, particularly in areas such as the soft palate and pharynx. 4. Other possible symptoms: Some infected individuals may also experience limited mouth opening, facial swelling, fever, and other systemic symptoms. If the above symptoms occur, timely medical attention is recommended to prevent further worsening of the infection and to protect oral health.
