My ‘sensitive’ toothpastes were so irritating I didn’t know what to do next. I took a chance and tried Coral Nano Silver toothpastes, and WOW! No irritation to teeth or gums, and my teeth feel clean all day! I love the cinnamon tea tree and mint, and my grandkids love the bubble berry one I gave them! No more complaining about having to brush their teeth! Customer for life 👍🏻 Thank you for an amazing product.
