Brushing a dogs teeth

I have started brushing Ranger and Snickers teeth, and while Snickers hates it, she will let you do it, Ranger on the other hand doesn't really care about it either way. My problem is that Ranger LOVES the toothpaste flavors (mint and peanut) so the entire time I'm trying to brush his teeth, he's trying to lick the toothpaste, which makes it really hard to get his teeth brushed. Any suggestions on making it easier, or moving his big ol' tongue out of the way?

 

I started with them as puppies just putting my finger in their mouth and rubbing the teeth. After the dog was used to this, I used a finger cot brush. And rubbed it on their teeth without any toothpaste. Slowly I introduced toothpaste. And then it was an easy transition to the brush.
This whole training process took a couple months to reach this point but I was patient because I will need to have their cooperation with this for may years to come!
By the way, I usually sat on the floor in front of the TV and had the dog just lay down and relax before I would start playing with their teeth.

And finally - my vet charges anywhere from $85-$100 dollars to clean teeth - that's a lot of money!. And the dog has to be sedated - a risk in itself!
