This toothpaste was recommended by my dentist. If you suffer from chronic canker sores, this is one step to reducing them. There are many factors that can trigger canker sores, such as stress, eating acidic foods or having poor nutrition overall, menstrual periods, food allergies, or trauma (i.e., biting your cheek or lip).
The reason this toothpaste works is because it does not contain Sodium Lauryl Sulfate, an irritating agent in most toothpastes. SLS has a drying effect on the protective surface of oral tissues. Once this protective layer has been compromised, the tissue underneath is more vulnerable to irritants such as acidic foods.
Try using this toothpaste for about one month and you will see a difference. A few years ago I always had canker sores, usually at least 3 or 4 at a time. I still get them occasionally, but not more than once a month. I am so delighted by the toothpaste that it is all I'll use, and if I try going back to normal toothpaste for even a week, I start to get canker sores again. I highly recommend it. I really do.
