A loose baby molar with a loose cap. Is it a big deal if the cap comes off before the baby tooth comes out?

My 8 year old grandson had caps put on his baby molars. Now the first of the baby molars has become loose and the cap is loose, as well. If the cap comes off before the baby tooth comes out, is it a big deal or can we just let the cap come off and the tooth come out on its own when it is ready.
