First, will you likely sicken and die because of what the dentist did? Well, if you've lived this long, likely not. Recalling back before aids, dentists did not used to routinely wear gloves. The gloves are probably more worn to protect the dentist than you. Why? Because there isn't much out there dirtier than a human mouth. That said, your dentist should not be picking things up from the floor and shuffling papers. My dentist has an assistant to replace anything dropped with a fresh, clean, new one and to do any sort of ruffling through papers. Normally, nothing like that happens anyways. He looks over the paperwork and x-rays before starting and doesn't drop much.
As far as dropping things on the floor goes, I saw one myth busters on it. They took some object and coated it with the type of broth used to grow bacteria in a Petri dish. I think it was on a floor tile. Then they dropped some dry items on it and some wet items. They incubated for a period and compared. The tiles that had had a wet item dropped on them had much more bacteria. No matter whether the item was picked up before 5 seconds or not, there was still bacteria.
Then they swabbed a bunch of areas of their workspace and compared how much bacteria incubated. Interestingly, the bathroom showed the least. They said this was because it was cleaned very regularly with cleaners that kill bacteria and the rest of their space was not.
Amusingly enough, my grandmother and great-grandmother always said kids need to eat a pound of dirt to be healthy. They pointed out the kids who had parents that did not allow them to play in the dirt or ever get dirty were always the sickest kids around. Today we have all these antibacterial products. People seem afraid their kid will look a germ in the eye, and now I read reports of kids coming down deathly ill with resistant strains because of all the antibacterial products. Besides that, a new study has come out saying the water in the natural aquifers is starting to show rising concentrations of the active ingredients in antibacterial products and they fear the damage this will do in the environment by creating more resistant strains.
I think bottom like sure we should keep things as clean as we can, but if your kid grabs a gumball up off the floor after they've dropped it and eats it, well. No big deal.
