Hi..choose any herbal paste and look for ingredients. Some of them don't have that ingredient like Himalaya, meswak, dabur red,patanjali etc. Regards

Some ayurvedic tooth pastes are SLS free and if i am not wrong sensodyne is SLS free. SLS is a foaming agent and present in soaps and shampoo we use. Though few ayurvedic preperations have added the SLS and claim the source to be coconut oil which is absolutely safe. Flourides are added to help remineralization process of intial cavities and mint & menthol add flavor, it also gives a necessary marketing edge. So your best alternative is a bland paste from ayurvedic companies such as Himalaya botanique. I am not here to promote any company, but confirming to the relevance of current query.
