I dunno but brushing my teeth with metal sounds scary - maybe the healing crisis had to do with trying to get the metal out of your mouth?
But ooops! I was looking at the wrong toothbrush!!! So I had to come back to edit the message
It says the solarday? one does NOT have metal bristles but some titanium rod in the middle - I am scared of titanium dioxide though - I hear it is bad stuff - but maybe there is no danger of it getting into your system. So if not it might be a cool thing.
Thanks - it was fun checking it out!
