Herbal Tooth and Gum powder

I don't have any gum or tooth problems but I want my teeth to look whiter, so recently I have started using this powder to brush my teeth every night. Is the powder supposed to be mixed with something to make it easier to brush? I decided to mix it with a little extra virgin coconut oil so it feels more like a paste AND tastes better, but I am not sure this is the right thing to do. Can I use the powder daily to brush or is there other product for this? Thanks. Tweet
