Most toothpastes contain SLS - we all know how drying this is for our hair, after all it was created to clean the grease off car engines and garage floors. This is the foaming agent found in anything .... well that foams including toothpaste. I havent used a toothpaste in years that contains SLS. But alot of the natural toothpastes dont contain flouride which is helpful for teeth.
I use a toothpast called SQUIGGLE ENAMEL SAVER- no SLS but has flouride, available over the net. Great product - has cut down on the amount of ulcers my son gets so thats a great thing. Fantastic service and immediate despatch.
