Is there a way to get cheaper dental care if you have little to no income?

I know I need two fillings and a root canal (or extraction). I can't find a job, but I'm looking every day. I really don't want these little cavities to get to where they need root canals too, but I have no money and no way of making any til I get income. My parents help me a little, but I need something that won't break them... I just don't know what to do. Is there a way to get cheaper care when you can't find employment?

Depending on where you live, there is almost always a city or county health dept which also provides dental services on a sliding scale fee (based on your income). If there are nearby universities with dental schools, they usually offer lower priced services. Do your best to practice good dental care in the meantime. Hold lightly salted water in your mouth a minute several times a day. Good luck!
