To be fair to the T/S he asked a specific question about the best guard for protruding teeth and I do not recall any threads dealing with that issue in G and E.That said I do hope he used the search function anyway....
To Harjunt,u could look thru a few of those threads and contact some of the companies in them or post in the mouthguard threads and see what they say about gumshields for persons with sticky out teeth?
If you scroll down to the bottom of the page,left hand side there are some threads about mouthguards...
Hopefully one might even answer the question in here......
