How should an avulsion of a primary tooth be handled if it occurred more than 30 minutes ago?

Extraction, space maintenance if needed
Replant, splint, soft diet
Soft diet only
Antibiotics only

The correct answer is: Extraction, space maintenance if needed

When an avulsion of a primary tooth (baby tooth) occurs more than 30 minutes ago, it is generally not recommended to replant the tooth due to the risk of causing damage to the permanent tooth germ. In such cases, the most appropriate approach would be extraction of the avulsed primary tooth and space maintenance if necessary. This helps prevent any complications and ensures proper development of the permanent teeth. Options B, C, and D are incorrect: - Replanting and splinting the avulsed primary tooth is not recommended after 30 minutes have passed. - Soft diet alone does not address the primary concern of managing an avulsed primary tooth. - Antibiotics alone are not the appropriate management for an avulsed primary tooth.
