[2025-10-01T08:17:19.753427] [PI reasoning] **Exploring enamel repair capacity**

I’m considering why dental enamel lacks self-repair capacity. Enamel is formed by ameloblasts, which are lost after tooth eruption, preventing regeneration. Once fully formed, the enamel loses its formative cells, making repair impossible. I might need to support this with reasoning or evidence, so a quick search about dental enamel repair and ameloblasts could be beneficial. It's interesting to dig into this topic further!
