Tooth fracture with pulp exposure: This is the most direct and common consequence of an open tooth fracture, where the fracture line exposes the dental pulp, potentially leading to pain, infection, or pulp necrosis.

Tooth fracture without pulp exposure: While less severe than a fracture with pulp exposure, this still represents a significant injury that can lead to sensitivity, pain, or further complications if not addressed.
Dental concussion or subluxation: These are injuries to the tooth-supporting structures without abnormal loosening or displacement of the tooth, which can occur in conjunction with or instead of a fracture.
Tooth avulsion: Although more severe, if the tooth is completely displaced from its socket, it could initially be mistaken for a severe fracture.

Mandibular or maxillary fracture: While less common than tooth fractures, fractures of the jaw can occur with significant trauma and must be identified promptly due to their potential for serious complications, including airway compromise, bleeding, and long-term cosmetic and functional issues.
Concussion or more severe head injury: Given that significant force is often required to cause an open tooth fracture, there is a potential for associated head injuries, which could have serious or even life-threatening consequences if not promptly diagnosed and treated.

Dental anomalies (e.g., dens invaginatus, dens evaginatus): Pre-existing dental anomalies could potentially mimic or contribute to the appearance of a tooth fracture, especially if the anomaly has led to a weakened tooth structure.
Pathological fracture due to underlying disease (e.g., odontogenic cysts, tumors): Although rare, a tooth fracture could be the first sign of an underlying pathological process that has weakened the tooth or jawbone, making it more susceptible to fracture.
