Fresh breath that actually lasts starts below the gumline.
A targeted gel that reaches the bacteria mouthwash and brushing leave behind — where chronic bad breath really begins.
If your breath comes back minutes after brushing, you're not doing it wrong.
You're just cleaning the part you can reach. The cause is somewhere a rinse never goes.

Honest about who it helps
The science
The ingredient that sets it apart
A licorice-root extract studied for reducing P. gingivalis, a key bacterium in periodontal pockets and a source of the sulfur compounds behind chronic bad breath.

Why we exist
Most oral care treats the smell. We went after the cause.
For years, chronic bad breath has been treated like a hygiene problem or a freshness problem — covered up, never solved. We built Oralvia around a different idea: reach the bacteria living below the gumline, where rinses and mints never go. Less masking. More fixing.
