Re: Who whitens their teeth here?
Ditto, that’s why I start using Sensodine the month prior to starting the strips because it helps “prep” the teeth. I don’t get sensitivity since I started doing that. I would recommend that for any form of whitening, be it baking soda or Hydrogen Peroxide.
And Reha, that’s the same Hydrogen Peroxide. You can add a drop to your toothpaste or make a paste by mixing in a bit of baking soda.
