Regular toothpaste is an environmental killer: 500 billion plastic toothpaste tubes end up in landfills each year. Tablets are the multitasking, planet-friendly upgrade. Free from sneaky ingredients and drying SLS foaming agents, our tablets come in glass bottles and compostable refill packets and are made with clean formulas that deliver whole-body benefits.

Duo is best experienced by mixing and matching the varieties that serve your health and wellness goals. As you find the routine that works best for you, you can customize your bundle by swapping out products. If you need refills for the guest bathroom, you can always add to your delivery.

We created Duo to make your mornings and nights - or whenever you brush your teeth - better. If we don't meet your expectations for any reason, we'll give you a 100% refund. All you have to do is email and we'll send you instructions on how to send back your product and receive a refund. You can pause, skip, or cancel your subscription at any time. We'll email you before your next shipment is processed so you'll never have any surprises.

Let’s talk about nHa.

Nano-Hydorxyapatite (nHA) is a non-toxic fluoride alternative that remineralizes your teeth and keeps them strong. It's quickly becoming the first-choice ingredient for dentists and patients alike for restoring and strengthening enamel, while also naturally whitening and treating sensitivity at the source.
