[2025-10-01T08:02:35.087050] [PI reasoning] **Confirming tooth development timeline**

I need to clarify when initial tooth development starts in embryos. I remember that dental lamina formation begins around the 6th week of intrauterine development, so I'll go with answer B. It's always a good idea to double-check that information quickly to ensure accuracy. Let me do a quick confirmation to finalize my answer!

[2025-10-01T08:04:18.790352] [PI reasoning] None of these records mention the 6th week specifically, but there are general sources that do. I think I could reference the Swiss dental journal, which mentions a timeframe of 28-40 days, or about 4-6 weeks. It makes sense to provide this within-text citation so it's clear. I’ll put together my reasoning for answer B and work on crafting the final response. It’s all about presenting the information clearly!
