I did the denture lab course. I thought it was an excellent course and I would highly recommend it. It really gave me the hands on experience in dentistry that I wanted to try before dental school. You actually make 1/2 a denture by melting wax onto the teeth. One note, this course was NOT easy. It requires patience and lots of practice. There is even a final. If you do well on the final, Mark will write you a LOR (only about 1/3 of the class got one). The course fills up pretty quickly, so reserve a spot ASAP!
