If you have been seeing it for years, I would say its a good thing. I would hate to think there are that many horses trotting around in bad bits or in need of dental care! Lol.
I am currently working on getting my horse moving from behind and onto the bit. We have been working a lot on collecting and sometimes he gives me what I call the "oinky" face. Where he is saying, No, I don't want to do this! But once he comes together and relaxes, he comes down and starts to chew a little bit, and then starts to salavate some. This is good, I want him relaxed and happy with the bit in his mouth. On a good day, he will foam a little more than before and is really listening. At least I believe this for my horse.
So its likely, as Kayty said, its all good!
