Dry socket is characterized by
1. episodes of sharp, piercing pain associated with sweet foods
2. continuous or almost continuous, moderate to severe pain with almost no adjacent swelling
3. continuous bleeding from the socket with swollen gingiva
4. indurated swelling with local tenderness and temperatures of over 101 F

📝 Explanation:

Dry socket (alveolar osteitis) is a painful condition that occurs after a tooth extraction when the blood clot fails to develop or is dislodged. The exposed bone and nerve endings in the socket cause a dull, aching, and continuous or almost continuous pain, which can be moderate to severe. A key characteristic is the absence of significant swelling or signs of infection (like pus or high fever) in the adjacent tissues, distinguishing it from an infection.
