Jeevee top right both premolars were extracted. They were very old crowns. I found the drilling required for them very difficult to cope with, so couldn't handle it again. Apparently a bridge for some reason, wasn't an option. They sounded good. I had no choice. Plastic denture snaps in very easily. I had it done by a private dentist during the pandemic, had to have it altered slightly as it was a bit painful. When I saw my nhs dentist she said she couldn't do any better. (I was willing to pay to have a new one). I could eat with it, it's very secure, doesn't need fixative, just all the plastic on the roof of my mouth makes it uncomfortable. Other people I know manage fine. It took a while to get used to talking with it.
I will never like it. However that's just my experience. Other people cope very well and as I say it clicks in very easily and never moves. My dentist was able to show me an example.
