Some horses need floated more often than others. When I first got Cinny I had to float him 3 times the first year! He is a nervous grinder though. Now that I have fixed most of the issues causing the teeth grinding (ulcers, mag deficiency, lack of confidence, etc) we are down to once a year. My old horse only needed done every couple of years.
I would stop thinking about what was or wasn't done in the past because it's a moot point right now and focus on what needs done now. Get a dentist out now, and I would stop riding with a bit until it's done. If the hooks are inward, you could cause a lot of damage to the tongue.
