Good points about spacing treatments out, but have you tried using sensitivity toothpaste between sessions too? I've found it really helps calm things down if my teeth start acting up. Also curious—do you think fluoride rinses alone are enough, or would you recommend something like remineralizing gels as well? I've heard mixed things about those, but personally had decent results when I was recovering from a whitening mishap a while back...

Honestly, fluoride rinses alone never did the trick for me. I ended up trying remineralizing gels after my wallet took a hit from a whitening disaster (lesson learned: cheaper isn't always better, folks...). The gels seemed to speed things along nicely, and sensitivity toothpaste was a lifesaver between sessions. I'd say give the gels a shot—your teeth (and your budget) might thank you later.
