Tables missing from database

I jacked up my site pretty good last week by deleting the “pomo” folder (I thought it said “poRNo”), which apparently disconnected the database from the site?

I’d exported the mySQL database but couldn’t get it to restore, so enlisted my host’s tech support. They said that they restored the database, but the site is still barely populated with content and I can’t login. Upon further examination, it turns out that the “wp_users” and “wp_usermeta” tables were not part of the backup. I can see the original db on the server, and those tables aren’t present. Is it possible I deleted them somehow? Or could they be served from another db? Is there a way to restore those tables specifically?
