In dentistry, a dry socket is a layman's term for alveolar osteitis. The alveolus is the part of the jawbone that supports the teeth, and osteitis means simply “bone inflammation”. Alveolar osteitis refers to inflammation of the alveolar bone following extraction of the tooth.
Alveolar osteitis is a painful phenomenon that most commonly occurs a few days following the removal of mandibular (lower) wisdom teeth. It occurs when the blood clot within the healing tooth extraction site is disrupted.
