I use a non-SLS toothpaste because I’m sensitive to SLS (Sodium Lauryl Sulfate). My mouth becomes sore after using SLS. SLS is a nasty chemical and tooth-wise the foaming is wholly unnecessary. I’ve heard from a number of dental assistants that it’s a marketing gimmick. I currently use Natean Sensitive –


I did used to use Sensodyne when I wasn’t aware of the SLS issues. Pre-2015 or so, Sensodyne used strontium acetate. They now use potassium nitrate as their desensitizing agent which some studies say is more effective. Sensodyne did a huge marketing push when they changed, to try to draw in buyers. Arm & Hammer Sensitive uses potassium nitrate. Colgate Sensitive uses potassium nitrate too. I know some people who switched from Sensodyne when Sensodyne changed their formulation. I’m not sure what one would gain leaving Sensodyne for Colgate Sensitive …?


Many studies find that all this sensitivity toothpaste is a marketing trick and it’s mostly a placebo effect. They say it’s far more important to NOT brush right after eating, because that often causes issues. “ “The reason for that is that when acids are in the mouth, they weaken the enamel of the tooth, which is the outer layer of the tooth,” Rolle says. Brushing immediately after consuming something acidic can damage the enamel layer of the tooth. Waiting about 30 minutes before brushing allows tooth enamel to remineralize and build itself back up.”


I of course happily still use a toothpaste that says “sensitive” on it because I fall for placebos. Heck, I have a butterfly-shaped ring on my desk to remind me to focus on my thyroid. So I’m all for using placebos to guide heathy behavior. The “Sensitive” reminds me to brush for 2 minutes with a soft brush and to wait the half hour before doing so.
