The price of dentures. According to the Healthcare Blue Book, which provides estimates of fair, median pricing for health services, a set of complete dentures should cost approximately $1,300.

But the need to replace dentures increases long-term costs. Editor's note: This is an updated version of an article originally posted on July 16, 2013.
