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.

    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.

    Already seeing amazing results!

    After a course of antibiotics, I had months of a bad taste in my mouth and a film on my tongue. After doing some research I found that certain strains of probiotics work to restore the mouth microbiome. I have been a long-time customer of Burst's other products, so I was really excited to see them sell an oral probiotic that had these specific strains in them! I immediately saw improvement, I no longer have that terrible taste and white film!! Thank you Burst!

    Probiotics

    I chew and swish these twice a day after brushing. Love getting to support the good bacteria in our mouth while eliminating the bad. Can also help with acid reflux and sinus issues.
