Getting dental work done by students at dental colleges is a cheap way to get teeth fixed, according to The Washington Post. Another cheap, and potentially free, way to fix teeth is to sign up for a government health program, as Medicaid's website notes.
Work done at dental colleges is often 50 percent cheaper than traditional dental costs, The Washington Post reports. Another option is to sign up for free or low cost medical health programs such as Medicaid or the Children's Health Insurance Program (CHIP). Each of those programs offers a range of dental services and payment options. The price of those services are dependent upon income level.
