Dry socket is a medical condition that occurs after a tooth extraction. It is a painful condition that can cause inflammation, infection, and difficulty in eating and speaking. It occurs when the blood clot that normally forms in the socket after the tooth is removed is dislodged or dissolves before the healing process is complete. Synonyms for dry socket include alveolar osteitis, fibrinolytic alveolitis, and localized osteitis. Other terms that may be used to describe this condition include socket infection, post-extraction infection, or postoperative osteitis. Regardless of the name, dry socket requires prompt attention from a dental professional to avoid further complications.
