What does a tooth splint provide after replantation of an avulsed tooth?

1. Stability to the tooth

2. Protection from infection

3. Alignment of the bite

4. Reduction of tooth mobility

The correct answer is: Stability to the tooth

A tooth splint provides stability to the tooth after replantation of an avulsed tooth, which is crucial for the healing process. When a tooth is avulsed, it is removed from its socket, and immediate replantation is paramount. However, to ensure successful healing, the replanted tooth needs to be secured in place to allow the periodontal ligaments to reattach and the surrounding tissues to heal appropriately. The splint stabilizes the tooth and prevents excessive movement during the initial healing phase, which is vital for promoting the best possible outcome for the viability of the tooth. While protection from infection, alignment of the bite, and reduction of tooth mobility are important considerations, the primary function of the splint in this scenario is to provide the necessary stability needed for the tooth to properly integrate back into the alveolar bone.
