What is the best way to brush your teeth in the usual way (absence of gingivitis, etc.)?
Position your toothbrush at a 45-degree angle to your gums. Use gentle circular motions to brush each tooth, or two to three teeth at a time. After thoroughly brushing each tooth, flick the toothbrush downward, away from the gums.

I remembered the health teacher at school, he always came with a toothbrush and a dental anatomy and taught us 
But he never said to use toothpaste, I only brush with a toothbrush and water 
What is toothpaste?😀 😀 😜
