Fix bad breath at the source

You brush. You floss. You scrape. You see the dentist.  

And still have bad breath?

It’s not always about hygiene. Even people who brush and floss perfectly can have odor-causing bacteria hiding deep in the mouth and throat. That’s because bad breath isn’t just about hygiene — it’s caused by odor-producing bacteria living on the tongue and in hard-to-reach areas of the mouth. Most products only mask the smell, leaving the real problem untouched.

This fixes it at the source.

    So Helpful

    I was recommended this product by my dental hygienist to help with some plaque build-up and overall mouth health. I've been taking them for months now! They really help me with morning breath, and my mouth doesn't feel gross when I wake up. Also, since it's a probiotic I'd like to think it's prevented me from getting sick when everyone else did.

    Hi Beth, thank you for sharing your experience. I am glad we were able to connect directly. Whitening results can vary based on the type and depth of staining, and for some smiles it may take additional treatments to see more noticeable results. We also recommend avoiding fluoride toothpaste immediately before use, as fluoride can temporarily interfere with whitening effectiveness. If you need any further help just reach out anytime! 💜

    Love these oral probiotics

    I used to have bad plaque that would form behind my bottom front teeth within days of having a cleaning at the dentist. Since using these probiotics my teeth are smooth.
