Size of Battery and Use of Toothbrush Stytle Device?

[Guest guest]

Neophyte here. Would appreciate help with a couple of questions. I have heavy

plaque and need root planing. Would very much appreciate detailed into on the

use of the toothbrush based device seen in the photo section. I mean one

toothbrush on the inside of the cheek on each side and then switched? If one

has a problematical tooth, can one put one toothbrush inside the cheek next to

that tooth and then the other toothbrush on the inside of the tooth next to the

tongue? I notice some are using 3 volts or 4.5 volts. What makes for the use

of lesser voltage? Other than discomfort, is there danger from use of 6 volts.

I am thinking that I will use electro therapy for several month before

subjecting myself to root planing. Thanks much for a great group.
