How long before I notice a difference?

Fresh breath improvements often come first — sometimes within the first week or two. Gum health takes longer; the clinical studies on our ingredients ran 8–12 weeks, and meaningful changes are best caught at your hygiene appointments. Think of Evena as a nightly habit that compounds over time.

I wear a retainer or aligners at night. Can I still use Evena?

Yes — once the tablet dissolves, seat your trays as normal. No waiting required. The probiotic strains work overnight whether your trays are in or not.

Why does the label say "contains milk"?

The probiotic strains are cultivated using dairy-based growth media, which can leave trace milk proteins in the final ingredient. If you have a known dairy allergy (not lactose intolerance), consult your healthcare provider before use.

What if I miss a night — or a few?

Don't stress. Probiotic colonization is cumulative, not all-or-nothing. Just pick back up where you left off — consistency over weeks and months is what matters.

Does Evena replace brushing and flossing?

No — it's the final step after both. Think of brushing and flossing as clearing the field, and Evena as repopulating it with the right bacteria.

Can I drink water after taking it?

Try to make the tablet the last thing in your mouth before sleep. Less saliva at night means the active ingredients stay in contact with your oral surfaces longer — that's the whole point of nighttime delivery.

Is Evena safe to use every night long-term?

Yes. All probiotic strains in Evena have established safety records, including FDA GRAS recognition. Unlike antiseptic rinses, which can disrupt your oral microbiome over time, Evena works with your biology — not against it.
