Thanks for the Thyme recommendation^.
Currently I use a Terradent
toothbrush (which is way better than most, and there might even be better; I'll have to look around a bit more) with Tea-Tree oil dental tape, Natural Dentist
brand mouth rinse and/or Neem mouth rinse, and Ayurvedic toothpaste
Coffee is overall not so great (especially if it has mycotoxins, which most coffee has, as most coffee is bad quality because it is not processed correctly), unless you Bulleetproof
it. Yerba Maté is better than coffee overall, and even better than Yerba Maté is the newly-discovered (for me) Guayusa, the latter of which has no tannins and no 'crash' that you get with most coffees. http://www.runa.org/http://www.amazon.com/gp/product/B004FS ... PDKIKX0DER
Definitely my favorite herbal energy tea^ ("Clean energy" is actually a perfect description of how Guayusa feels).
And coffee is probably worse for one's teeth....
