As a general dentist its me who sees the results of kids who only have sports shop mouthguards or ( heaven forbid ) none at all!!!
Orthodontists correct misplaced teeth with braces but don't have to carry out root canal treatments and repair smashed teeth (or stitch smashed faces) after contact with rugby ball/ hockey stick etc. So I am suprised that a professional colleague would suggest that substandard protection would suffice if not playing at an advanced level! In my daughters class the LESS co-ordinated kids are the ones who are more likely to miss a ball/ misplace a stick etc, not the athletically gifted!
PLEASE don't accept anything less than a properly fitted dental mouthguard made by your dentist. And replace it as soon as it doesn't fit any more. I have had to put right too many ruined smiles not to feel this strongly!
Your childs smile and your peace of mind is so important- if you're willing to go to all the trouble of getting them into the best schools surely something as simple as a proper mouthgaurd is NOT the place to skimp....
I promise to get off my soap box now.
