I love the cinnamon flavor except I can only use it for a few days at a time or else my gums start bleeding. My gums are normally fine and not sensitive at all so I can't imagine what's in the cinnamon toothpaste that is so irrating. Oh well - still love the taste!
I've found that the Crecst cinnamon burst in the tube is fine...but the "liquid-y" one in the "other style" container (heheh - I dont' know what it's called!) irritated my mouth/lips after a while.
I love love love Herbal mint! So light! I used Aquafresh this morning and it felt like I was brushing my teeth with a candy-cane for some reason!
