FAQs
Do I need to swallow? How do Duo supplements work?
Nope! Supplements like vitamin D3 and vitamin B12 are absorbed when they come into contact with the tissues in your mouth. This is called mucosal absorption. When you brush with Duo, these supplements efficiently reach your system without needing to be swallowed.
Why do you use nano-hydroxyapatite instead of fluoride?
Exhaustive research over the past several decades has proven that nano-hydroxyapatite is just as effective as fluoride at preventing cavities and remineralizing teeth, while also whitening them and reducing sensitivity.
How does Duo help with sensitivity?
Other methods of decreasing sensitivity, such as the potassium salt found in Sensodyne, only patch the problem of sensitivity by soothing nerves that send pain signals to the brain. The nHa in Duo directly addresses the cause of sensitivity by repairing open dental tubules -- the access points to dental pulp and nerves -- and prevents painful stimuli from reaching those nerves in the first place.
How does nHa whiten your teeth?
Nano-hydroxyapatite (nHa) restores the natural brightness and whiteness of the tooth surface by creating a new smooth and glossy layer of enamel.
Why are toothpaste tablets better for the environment?
Duo toothpaste tablets come in glass bottles with aluminum caps that are completely recyclable and reusable, and refills are available in compostable refill pouches. Traditional toothpaste also generates significant water waste in its production in order to maintain a paste-like consistency.
Why doesn't Duo use SLS or other surfactants?
Most toothpastes include sodium lauryl sulfate (SLS) to create the foam that we are all used to while brushing. SLS is what is used in soaps, detergents and shampoos for foaming and its antimicrobial properties. The problem it is that is harmful to your oral health: it dries out your mouth and causes irritation. Duo's foam is created using our proprietary, SLS-free formula to keep your mouth healthy and hydrated.
