Let’s Talk About Alcohol

Alcohol carefully disperses our essential oils to cut through biofilm. It also lets you Feel the Whoa! - our famously intense, signature sensation.

But we totally get that alcohol may not be everyone’s cup of tea. So, we also created alcohol-free products that are made using essential oils dispersed in a different way, these products offer an alternative mouthwash experience – while also providing a whole mouth clean.
