We write a lot about dental hygiene here at HuffPost Shopping. Needless to say, when we spotted a restorative toothpaste that reviewers say stopped hot/cold sensitivity and lessened tooth pain, we needed to know everything. Made with a generous 10% nano-hydroxyapatite, a government-studied calcium-based compound for restoring and protecting teeth, this fluoride-free, mint toothpaste from Mouthology may be your next dental buy, especially when it’s on sale for under $10.
The magic comes from nano-hydroxyapatite, an engineered compound that mimics the natural material found in your teeth.
Without boring you to tears, studies show that approximately 70-90% of our tooth enamel is made from a calcium phosphate called hydroxyapatite. The shining star of this toothpaste is nano-hydroxyapatite, a human-engineered version of the material that’s highly biocompatible, i.e., welcomed nicely by the rest of your body. The substance has been studied a ton and is often used in dentistry, specifically for its ability to restore enamel, fill in tiny holes, reduce sensitivity, ward off plaque, and generally strengthen teeth.
Reviewers who have tried the toothpaste seem to agree, reporting an improvement in their teeth without “harsh foaming or irritation.”
