Re: tooth powder?
'Glad to hear your teeth/mouth enjoyed it!
You don't have to worry; it won't stain your teeth...if it did, there'd be thousands of people walking around with stained teeth (and just as many notes all over the internet)...and Dr. Christopher's company wouldn't still be selling it.
Yes, I suppose the herbs could discolor the plastic bristles of some toothbrushes. I use it once or twice a week, and although it's messy, it's never stained my toothbrush bristles, or my sink...but I don't have a porous, marble sink :( We've never had any one else report that happening.
I'd think if you kept the water running in the sink/basin and only spit the tooth powder into the running water, it wouldn't be likely to stain. Even regular toothpaste can/will 'stain' sinks - I still have an old tube of Crest that I use to UNstain my sink (and remove the mineral build-up from the around the faucet).
I'm sorry there weren't any type of instructions - I didn't realize people needed instructions on how to use tooth powder (duh me) - what you did was correct. Just wet the brush and 'dip it in' or sprinkle it on (that's the only way I can think of to do it). People also use this to pack around their gum-line to prevent & treat periodontal disease.
Happy brushing!
