I have extremely weak enamel so regular flouride rinses are simply a MUST for me. ACT is the only product that takes the throbbing edge off my front teeth. Whenever I miss a daily rinse, it's nearly intolerable to drink anything that isn't room temperature. I love ACT!!
I've tried all the flavors and I've found that cinnamon is the best for my already sensitive teeth. Surprisingly, unlike the shockingly strong mint, it is actually quite tame and allows for a full 60-second rinse. The mint left me with such a strong burning sensation, I was never able to complete the recommended rinse time.
