On the cheap or “discount denture” end, you get units with premade fits that often look artificial. Less expensive sets are generally made with lower quality materials and their warranties reflect that. In the end, cheap dentures lack the desired lifelike look, are more prone to crack or break outright, may have poor bite alignment, and are typically less comfortable.
The office people and assistants must be low wage workers. They have the typical low paid, high stress lack of concern for the patient. The person who did my form did not do it well. That was evidenced in the quality of the temporary denture. The Dentist who did the extractions was the absolute best dentist I have ever seen in my 55+ years. They give you a pill to take an hour before you get there and if needed, one when you arrive. It relaxes you and one was enough for me. I was ready to go to sleep. They took me straight in and the dentist took 20 minutes numbing every tooth with a local anesthetic. <<<<
