Could any one help me please

Hello there i just graduate from a technical school here in the US as a dental assistant, and i look forward to move on to the next step as dental hygienist, my top goal is to be a general dentist but to be honest with you guys, as you know here in the US is very expensive to study in the dental school, so i'm looking for other choices and i heard about Ireland and it sound very interesting, my question is how can i move from the US and continue my education overseas in a place like Ireland? i would love to heard from you guys, thank you very much!
