Dry socket, also known as alveolar osteitis, is not a type of infection but rather a condition that occurs after a tooth extraction. It occurs when the blood clot that typically forms in the socket where the tooth was removed either fails to develop properly or becomes dislodged prematurely. This exposes the underlying bone and nerves to air, food particles, and bacteria, leading to intense pain and discomfort.

While dry socket itself is not an infection, it can increase the risk of infection because the exposed bone and tissues are more susceptible to bacterial contamination. However, dry socket is primarily characterized by severe pain rather than the presence of infection.

To prevent dry socket, it's essential to follow post-extraction care instructions provided by your dentist, which may include avoiding vigorous rinsing or spitting, not using straws, and following proper oral hygiene practices. If you suspect you have dry socket or are experiencing severe pain after a tooth extraction, it's essential to contact your dentist for evaluation and treatment.
