Founder Letter: “Smile Filter was a dream”

Hi friends,

We all know teeth and gums get all the oral care love. But your tongue? It’s home to over 700 kinds of bacteria and can make all the difference for your breath, taste buds, and overall mouth feel. Tongue scraping isn’t new — it’s been around for centuries! — but most scrapers are plastic, clunky, sharp, or get shoved in a drawer (where they feel kind of gross).

I wanted something better. Something you want to keep out. So we made our Smile Filter Tongue Cleaner: medical-grade stainless steel, a one-handed design, and a stand that keeps it upright, clean, and ready. We’ve jokingly referred to it as the Rolls Royce of tongue scrapers, but honestly, it is. It’s a beautiful work of engineering — and literally the finishing touch your oral care routine can’t go without.

It’s the one step I never skip and I hope you won’t either.

Stay smiling,
Dr. Chrystle Cu
