What's inside, and what it does for you
Mornings without the pink
Two live gum strains. They crowd out the bacteria that make your gums bleed, so you stop bracing yourself every time you spit.
Stand close, talk close
Zinc. It knocks back the bacteria behind inflamed gums and bad breath, so you stop thinking about your breath up close.
Your routine finally pays off
A slow-melt lozenge with xylitol. It melts over minutes, not seconds like a rinse, so the good bacteria stay on your gums and all the brushing and flossing you already do starts showing up in the sink.

Questions people ask first
How soon will I notice a difference?
In the trials, gums changed within two weeks. Check your sink on day 10. Keep going after that: gums keep calming with daily use.
What’s actually in it, and how do you know the bacteria are alive?
Two strains of Lactobacillus reuteri(DSM 17938 and ATCC PTA 5289), 200 million live bacteria per lozenge, plus 2 mg of zinc, in a slow-dissolving mint-flavoured lozenge sweetened with isomalt and xylitol. No sugar and no alcohol. They’re live when they reach you, and they stay live until the date on the jar.
Do I stop flossing?
No. Brushing and flossing clear the film. AVIRO changes what grows back. You need both.
I’ve tried everything. Why would this be any different?
Everything you’ve tried takes bacteria away: the brushing, the floss, the rinses. None of it changes which bacteria grow back afterwards. That’s the one thing AVIRO does, and it’s why it works alongside your routine instead of replacing it.
Do I have to take it forever?
Your gums grow bacteria back every day, so AVIRO works while you use it, the same way brushing does. Most people keep it in their routine to keep their gums healthy. You can skip or cancel any time.
How many a day, and when?
Two a day: one after brushing in the morning and one at night. Let it melt slowly, and don’t chew it.
Is it chalky?
No. It’s a smooth lozenge with a fresh mint flavour, and it melts over a few minutes.
Can I take it if I’m pregnant, wear braces or take medication?
This strain pair has been studied in pregnant women and in people wearing braces. If you take blood thinners, bleeding can have another cause (see below).
What if I still bleed after 30 days?
You get your money back under the Sink Guarantee, and you keep the jars. Bleeding can also come from hardened tartar below the gumline (that needs a professional clean), hormones, smoking, blood thinners or low vitamin C.
