What primary complication could arise from a dental extraction?

The primary complication that could arise from a dental extraction is a subperiosteal abscess. After an extraction, infection can develop in the area where the tooth was removed, particularly beneath the periosteum, which is the layer of connective tissue that covers the bones. If bacteria infiltrate this area, it can lead to the formation of an abscess, which is a collection of pus that causes pain, swelling, and potentially systemic issues if left untreated.

While other complications like jaw deterioration, tooth misalignment, and gum recession can indeed occur, they are generally less immediate concerns following an extraction. For instance, jaw deterioration is more often associated with prolonged bone loss after tooth loss rather than a direct result of the extraction itself. Similarly, tooth misalignment occurs over time when adjacent teeth shift into the space left by an extracted tooth but is not a direct complication. Gum recession can result from various factors including periodontal disease and improper oral hygiene, and while it may be exacerbated by extractions, it is not classified as a primary complication in the immediate aftermath of a dental procedure. Thus, a subperiosteal abscess represents a serious and recognizable risk that can emerge rapidly following an extraction, making it the correct focus in this scenario.
