GAELIC football is top of the league when it comes to child players suffering dental injuries despite gum shields becoming mandatory last year.
It is followed by hurling and rugby, according to a survey of dentists who said the "no gum shield, no game" policy should be strictly enforced.
The next highest injury toll comes from cycling followed by soccer and hockey.
Ireland has one of the highest rates of sport-related oral injuries in the EU. Sport accounts for one-third of all visits by adults to the dentist with problems such as chipped and knocked out teeth.
Dr Sean Malone, president of the Irish Dental Association, which carried out the survey, said: "The findings showed the importance of wearing a gum shield or helmet when partaking in sports."
