Hi grandma. I would recommend getting the youth sized clear mouthguard here, on this page. Alternatively, you can go here: pr-mo-01. There are clear options there as well, but you may have to trim the mouthguard down for the youngster.

Hey Vivi. I know we have this guard: pr-mo-141 which is particularly for braces, but unfortunately it doesn't cover the bottom teeth as well. The brainpad guard (Above) is a great double layer guard but isn't particularly for braces.

That being the case, it could be hit or miss on how well it suits you.

I know of one guard that we don't carry that might suit your needs as well: http://www.amazon.com/Shock-Doctor-Double-Strapless-Mouthguard/dp/B0028R2XDK/ref=sr_1_1?ie=UTF8&qid=1314732475&sr=8-1.

So consider those options and let me know if you need any more tips!

Hey Denise. As far as I know, most competitions don't require double or single, so long as you are wearing a mouthguard of some variety.

Since the brainpad comes in youth sizes, I think you could buy with confidence here. Mouthguards take some getting used to, but the fit should be good for him.

I think they would like this model: pr-mo-183. It is cut to be unobtrusive and won't ride high on their gums.

If they are used to the feel of full mouthgaurds go with adult. If they are not, start at youth and work up to adult.
