Wednesday/ ditching the whitening

I read once that Americans have somewhat of an obsession with super white teeth – so that must be why so many toothpastes are ‘whitening’ or ‘extra whitening’.

Well, says my dentist:
1. if you are using toothpaste for sensitive teeth, whitening ingredients detract from the effect of the potassium nitrate (which helps with tooth sensitivity); and
2. the amount of whitening actually achieved with toothpaste is minimal.
So I’m ditching my Sensodyne Extra Whitening toothpaste, and will go with one that only has the potassium nitrate.

I got this toothpaste sample from my dentist, and I like it, but I have not been able to find it in a store yet. I guess I could order it online from You-Know-Who, but I will try another store or two first. The dentist says to smear a little toothpaste over the tooth and gums where the heat & cold sensitivity is, before brushing, to amplify the effect of the potassium nitrate.
