How can I get cosmetic dentistry for free or cheap in US?

Check for Dental Colleges in your area.The dental students need people to practice on.Don't be alarmed that they are ';practicing'; ,they are supervised by very compitent Dentists Instructors.I was a dental assistant and have seen very nice work done by students,especially from Loma Linda University,Northwestern,UCLA,Nebraska U. and several Dental Colleges.Also , these services are not easy to come by so plan ahead and good luck.
