The longer it takes to write this letter, the stronger my case becomes. I have just purchased a new tube of your Weleda toothpaste (Pink with Ratanhia). In reading the enclosed materials, I was again reminded that I’ve wanted to share my experience of the past six years. Formerly the customer service manager for a leading natural skin care company, I came in contact with many people. On the phone one day with a customer, I was informed about the possibly bad side effects of sodium laurel sulphate on the inside of one’s mouth. I already knew some negative things about this ingredient but had never made the “oral” connection. Having been plagued with canker sores nearly every month of my entire life, this really hit home. Those tiny, white, pin-head-sized dots that show up on the inside pockets of the cheeks are extremely painful, as many people know. It was pointed out to me that SLS causes such a severe chemical imbalance inside the mouth that the result for some people is those nasty little blights. I thought it was always a hygiene issue! Immediately, I went out and purchased your Plant Tooth Gel to give it a run. Why did I choose your brand? Well, Weleda! It was the only one I could find. Every other brand out there, including Tom’s, which calls its toothpastes “natural,” had sodium laurel sulphate in some form or other. After six months free of sores, I was a follower. After one year, I was touting the find to friends, my dentist and hygienist. I even went so far as to test your other flavors, all with the same satisfying results. I am completely convinced it’s the absence of SLS. Six years hence, I will tell you that I have NOT HAD ONE canker sore. Not one! I’ve been meaning to write this letter for a long time. Like a fine wine, this case has only matured. Most importantly, thank you for stepping outside the box to create something great!
