Be fair now, in the process of their career, many rugby players lose teeth.
It could be because they lack stability when running, therefore are subject to more tackles and are therefore kicked in the mouth.
with BR insoles they would be stable, would be tackled less, would not lose their teeth, would therefore have a higher gait velocity and would therefore not be subject to losing their teeth.... I think that I'm losing the will to live.
