I'm majoring in dental hygiene and I found out that I can get a job with just an associates degree. Is there a disadvantage to this or would you advice me to just go on to the bachelor's.
Also, do you have to have a bachelor's degree before you can get your master's?:p

Usually, those with a higher degree find it easier to get a job (with more money). Go for the Bachelor's. Also, some programs allow you to get a Master's as part of a 5 year course of study. Ask if it is possible at your school
