Can you please suggest me a good toothpaste which does not contain any harmful toxic chemicals like sls, paraben etc. Currently I'm using sensodine since I have very sensitive tooth but I'm not very satisfied with sensodine since it also have harmful active ingredients like sulphate etc. And my mouth gets irritated after brushing with sensodine. I can't use ayurveda toothpaste since I'm allergic to herbal products. Please suggest me a good toothpaste for sensitive tooth.
