Not very - cows eat a great deal of vegetation, which means their teeth have evolved to have deep grooves and ridges to increase surface area for grinding. This causes feed to be trapped within the grooves where it ferments and rots until it falls back out. In addition, cows are ruminants, which means they regurgitate (puke up) sections of food (cud) they already swallowed and re-chew them. Part of that cud will be the bacteria and protozoa that live in the cow's stomach.
They lick them with their tongues.

No you would not want to put your face that close to a cows udder as you may get kicked, you clean them with your hands and milk them but no licking.

Of course they can, but the larger danger is that bees if attacking a cow or horse will be attracted to the mouth and nose and suffocate the animal.
