Yep, you can't stress that enough. I'm going to have 3 teeth pulled tomorrow. I have none on the bottom on the passenger side now, and after tomorrow I won't have any on the bottom on the driver's side. Then I have to have the small ones in front pulled, then a couple more on the top on both sides, then I get dentures.
It will be about six weeks after they're all pulled until my gums are healed enough for the dentures, so I'll probably be eating a lot of camel's🐪 soup for a while. I could get a temporary plate in the meantime, but my dentist said that would cost me about $1,000 and it would go in the trash, so I'll just make do with what I got. He said it was actually better to let them fully heal before I got the dentures anyway.
