 And how long do your dentures last for typically? Oh, I've had people since I've started, 40, 30, 40 years. Stop it. But I also have had people six, seven years. You know, a lot of people, sometimes people lose weight and their dentures just get very loose and no fitting. Sometimes they want a different color on their teeth, you know, because, or their lips have shrunk in, so they need another denture. But I've had patients where they've had them for 20, 25 years. Everybody's different.
