In fairness to the dentist, he or she is taking on the expense of the equipment and drumming up business. I would say for basic denture tech (no implant) train them yourself (takes time) start $35,000 -$40,000 per year. Experienced denture (no implant) starting at $45,000-$60,000 per year. Then you move up to denture /implant specialist, forget training them yourself. If you are lucky enough to find someone that does both, then you could try to start at $60,000 but you would need to sweeten the deal with a great work/ life balance and make sure everyone in the office knows who's boss (don't let the wife/husband and or front desk call the scheduling shots.) Also in either case, offer 401K , medical and yearly raises.
Well, I had to edit because I actually went back and read the original post. Yeah, you will need to hire two techs for this position, you won't find one that can do both fixed and removables. I can only speak for the removable side.
