Tartar fighting toothpaste typically has sodium fluoride (NaF) as its active ingredient. Colgate sensitive toothpaste has arginine, sodium monofluorophosate and calcium carbonate as its active ingredients. The Colgate toll free line is 1-800-268-6757.
Sensodyne ProEnamel uses potassium nitrate and sodium fluoride. I noticed some sensitivity toothpaste also used some kind of sulphite as well. I couldn't find any Sensodyne that used sulphites anymore. Hmm, wonder if this is related to the sulphites in wine issue that sometimes crops up!
Wonder why they don't list them as tartar fighting (ProEnamel would seem to fit the bill).
