FAQ
About Arbor Oral Probiotic
What is Arbor?
Arbor is a dissolving oral probiotic tablet containing two clinically studied probiotic strains — Lactobacillus reuteri and Lactobacillus salivarius. It dissolves nightly in your mouth, seeding your oral microbiome with beneficial bacteria while you sleep. Unlike gut capsules, Arbor works at the source of the gut-seeding pathway — before bacteria ever reach your stomach.
How is Arbor different from a regular probiotic?
Most probiotics are capsules that target your gut directly — but they have to survive stomach acid first, and many don’t. Arbor dissolves in your mouth, seeding beneficial bacteria at the very top of your digestive tract. Because you swallow approximately 600 times a day, every swallow carries those bacteria downstream to your gut — naturally. Arbor complements gut probiotics; it doesn’t replace them.
Is Arbor TGA listed?
Yes. Arbor is listed with the Australian Therapeutic Goods Administration (TGA) and manufactured in Australia to GMP pharmaceutical standards.
What strains does Arbor contain?
Two strains: Lactobacillus reuteri DSM 17938 (200+ clinical trials, naturally present in healthy oral and gut microbiomes) and Lactobacillus salivarius UCC118 (native to the human oral cavity, crowds out odour-causing and inflammatory bacteria).
Taking Arbor
When and how do I take it?
One tablet, every night, after brushing. Place it on your tongue and let it dissolve slowly. Don’t rinse or drink anything for 10–15 minutes after. Night use is important — saliva production slows while you sleep, giving the strains maximum time to colonise.
Can I take it with antibiotics or mouthwash?
Avoid taking Arbor within 2 hours of antibiotics or antibacterial mouthwash (e.g. chlorhexidine). If on a course of antibiotics, wait until the course is finished before resuming Arbor.
Is it safe during pregnancy or breastfeeding?
Both strains have strong clinical safety records. As with any supplement, consult your healthcare provider if you are pregnant, breastfeeding, or immunocompromised.
Results & Timeline
How long until I notice a difference?
Days 1–3: Fresher breath (most customers notice within 72 hours).
Weeks 1–2: Oral comfort improves, gum sensitivity often reduces.
Week 3–4: Gut improvements — less bloating, calmer digestion.
Month 2–3+: Compounding effects — the deepest improvements happen here.
I’ve been taking it a week with no change. What’s happening?
Breath improvement comes first. Gut effects take longer — the oral microbiome needs to shift before downstream benefits activate. Give it 30 full days of consistent nightly use. If you notice no change at all, our guarantee covers you in full.
