You don't need radiographs to back those toes up more and I would advise getting them backed as soon as possible. That said, radiographs never hurt.
If the person doing the work knows how to measure sole depth using collateral grooves, and knows not to carve into soles that are too thin, then there shouldn't be a problem.
