My first impression was that the consistency was different. It is not as paste-y as say a Colgate or Crest toothpaste. It also has a strong minty taste. It did not taste like peppermint to me but I guess its because the peppermint "flavor" I'm used to is full of artificial sweeteners which are probably not good for your teeth. The potency of the mint flavor is not overwhelming and it does leave you with fresh breath for a fairly long period of time.
