I just dropped 3 grand for two chunks of plastic that the yaehoo that made them left sharp edges all over them. every one of those burrs in time started rubbing a sore spot in my mouth. I've been a machinist for 30 years. not since I was a child have I had so little respect for my work as to leave edges that could cut you open on my work. affordable dentures should not mean sloppy craftsmanship. get some self respect you hotdogs.
