Hi Kevin, I do brush my guys teeth, but have done this since they were 10 weeks old. It is easier if you do it from a young age, but still can be done at home quite easily. I sit on the floor with their bodies facing away from me, and place their head on my chest, then I brush their teeth. I use the Arm and Hammer products from Petsmart, it comes in a kit with a toothbrush, finger toothbrush, and beef flavoured toothpaste. If you find it difficult to use the toothbrush, use the finger brush it's much easier to use. You can do it once every two weeks, and use bones and chew toys in between. Doing it sometimes, is better than not at all. Even if you think you aren't getting in there, and doing a good enough job, you are doing some brushing, which is also better than none at all. I wouldn't put them under anesthetic to clean their teeth, because of the risk, you would have also have to do it too often, which could also be expensive. My groomer has taken a course for cleaning and scaling teeth, so I let her do their teeth about every two months, if you do it regularly and maintain, then they shouldn't get too much of a plaque buildup, and it can be removed easier by the groomer. See if you can find a groomer who cleans and scales teeth in your area.
