Are bad breath and taste disturbances that occur after impacted tooth extraction a sign of infection?

It is perfectly normal for patients to experience mild bad breath and a metallic/bloody taste in their mouths during the first few days following surgery; this is a natural side effect of blood clotting and tissue healing at the wound site. Small food particles trapped between the stitches can also cause odor. However, if bad breath worsens 3-4 days after impacted tooth extraction, if there is a persistent inflammation, bitterness, and unpleasant taste in the mouth, and if these are accompanied by severe, throbbing pain (dry socket pain) and swollen lymph nodes in the neck, this is a clear sign of infection (alveolitis). In such a case, it is essential for the patient not to wait at home but to immediately consult a doctor to have the wound cleaned and dressed.
