Early exfoliation of teeth before five years of age may be caused by all of the following except?

Early exfoliation of teeth in children can occur due to various underlying conditions and circumstances. Cherubism, trauma, and immune deficiency all have mechanisms that could result in premature tooth loss.

Cherubism is a genetic disorder characterized by the proliferation of bone that can affect the jaw, potentially leading to displacement or loss of teeth. This condition can result in early exfoliation due to bone changes that disrupt the normal dental architecture.

Trauma, whether from an accident or injury, is a common cause of early tooth loss in children. A severe blow to the mouth can compromise the integrity of the teeth and supporting structures, leading to exfoliation.

Immune deficiency is another relevant factor. Children with immune deficiencies may experience dental issues, including increased susceptibility to infections that can promote premature loss of teeth. Oral health can be significantly compromised due to the body’s inability to fight infections effectively.

Localized aggressive periodontitis, however, is typically associated with older children and adolescents and is characterized by the loss of supporting structures around teeth, often as a result of specific bacteria. Although it can lead to tooth loss, it is less likely to present as an issue before the age of five, making it an unlikely contributor to early exfoliation in very young children. Therefore, it
