I've not been near a hockey pitch for several decades, so haven't ever thought about mouthguards and the logistics of coping with baby/adult teeth.
DD's junior school requires a medium-weight (Hi impact) mouthguard which OPRO will do at school for a mere £47.85 or I can organise one for ourselves.
DD (6) has only lost 2 baby teeth (and she has 4 back teeth coming through). Sods law, she'll lose her front top teeth within a week or so of the wretched fitting (or her back teeth will grow much bigger).
Does this mean I'll need to buy a new gumshield every few months or so?
I reckoned Mumsnet would be the best place to ask.
