Dentists definitely do not recommend this tooth brushing technique!
We will guarantee that four out of five dentists do not recommend brushing your teeth this way. A Japanese kid recently posted a couple of videos where he shows what it's like to brush your teeth with an air gun.
Now before you jump to any conclusions on how absolutely insane that is, (don't worry it's still a little insane) we should mention that he strapped a toothbrush to the air gun and isn't in fact using the air gun as a toothbrush. So already he's thinking a little ahead. The kid fastens the toothbrush to the air gun and shoots it a couple of times and in the kickback action of the gun, he brushes his teeth with the toothbrush. It clearly hurts him, but the young guy doesn't seem to mind as he just keeps on doing it! Check out the insane and pretty funny video of the wild toothbrushing technique.
