Love the idea but it isn't ready for use
I think the first time I rated it I gave this a good rating but I have been to the dentist since then so I have to change my rating.  The wood needs a little more sanding before it is ready to put into the mouth.  I used various course/fine sand paper on the wood before I used it.  The bristles were hard so I ripped up my gums using it.  For the first time in my life, I had gingivitis.  I ended up purchasing an electric toothbrush and came out of the dentist office with a much better gum/tooth score. As much as I hate adding to landfill with the plastic, I have to go back to something that is softer and cleans better.  I'll use the rest of these brushes for house cleaning.
