I honestly think its the same chance as seeing a licensed dentist some are just better than others.

There are no dental colleges near me , closest is over 100+ miles away .. My local dentist is amazing . but I lost my insurance so I can still go I just have to use the dental insurance that they have .. Its a private insurance and the interest is pretty high but it will allow me to get my work that I need done and I can just make monthly payments. Just another option you may need to look into.
