Hi
My wages are being garnished for an unpaid dentist bill, there takeing 25% of my paycheck which comes out to about 300 to 350 a month. I have $425 a month rent, plus a lot of other bills to add to that. It makes things very tight every two weeks and I'm not sure if there is anything I can do to help stop them. I have no credit or anything not sure what to do.

Nope, other than quit your current job and finding a new one. There is no way to stop it. Find a part time job to help you out until you pay it off. Remember in the future, as long as you make a monthly effort to pay a bill, they will not take you to court.
