Pretty much yes, holding your brush at 45 degrees and following your gum line. I found I could feel and follow my gum line except on my back upper outside molars where I had to turn the brush about 30 degrees up (in the front to back direction). For some reason I can't feel that part of my gums very well. I'm pretty sure your mileage may very.

It's also helpful to have a reliable hygienist check how you're going until you get it right. I'll probably end up going about every six months in any case, with healthy gums. Which is much better than "I would hate to see you lose all your teeth." which is what my hygienist said before I got serious.

Finally, I've only been brush once a day, before bed for two reasons. First to check how well things were going and second, to avoid too much wear and tear on the gums in case it wasn't necessary. As it turned out I'm fine with once a day. The primary way I check between check ups is to floss about once every two weeks. If my gums bleed then it's a sign I'm off track. Before I started this technique my gums would almost always bleed.
