Jafa,

It sounds safe to me. There are theoretical problems with bringing negative

charges in your mouth, which depend mostly on the strength of them compared to

the strength of the ionic bonds in your teeth. I very much doubt that this

brush would pose any such problem, but couldn't know without much more

information.
