Digestion starts here.
Chewing breaks food into smaller pieces. Saliva moistens it and starts breaking down starches before you swallow.
Your mouth. Your gut. Connected.
Mouth bacteria can affect your gut.
Everything you swallow passes through your mouth. Start there.

Saliva Testing
An optional at-home saliva test, with results reviewed with a licensed dentist. Sold separately from membership.
Before it reaches your gut,
it starts in your mouth.
Your mouth is the first stop in digestion. Give it a place in your daily health routine.
Microbes travel, too.
Swallowing carries oral microbes onward. Researchers are studying when certain mouth bacteria can settle in the intestine and contribute to inflammation.
Start with daily care.
Brush, clean between your teeth and tell a dentist about bleeding gums or recurring mouth concerns. Keep your regular dental visits.

About the mouth–gut research
A 2017 study found that certain bacteria isolated from human saliva could colonize the intestines and promote inflammation in susceptible mice. It does not show that swallowing bacteria causes gut disease in everyone, or that oral-care products prevent or treat digestive disease.

Frequently Asked Questions
Your mouth is the first part of your digestive tract. Chewing and saliva start digestion, and swallowing carries food, saliva and oral microbes onward. Read the NIDDK overview ↗
No. Reaching the gut and establishing a lasting population are different. Researchers are studying when oral bacteria can settle in the intestine and how that relates to inflammation.
OneOral provides oral-health care. Its products and saliva testing are not treatments for IBS, IBD or other digestive conditions. Bring persistent digestive symptoms to your medical care team.
No. The optional saliva test looks for selected oral microbes and measures features of your saliva. It does not measure your gut microbiome or diagnose a digestive condition. Testing is priced separately.
There are three plans. OneOral is $9.99/month: message a licensed dentist and share photos, get ongoing dentist check-ins, and pay member prices on kits, whitening and gum. Nothing ships automatically on it. OneOral+ is $29.99/month and adds a Treatment Box (CariFree Maintenance Rinse and Gel 1100 toothpaste) every 3 months with free shipping. Power Pack is $44.99/month: the Treatment Box plus whitening, energy gum and breath mints or oral spray. Sales tax is added where it applies.
OneOral renews monthly; cancelling stops the next renewal and access continues until the end of the period you paid for. OneOral+ and Power Pack bill monthly in cycles of 3 payments per box. Cancelling stops the next cycle and its box; the remaining payments for the current cycle are still collected on their normal dates. Full details are in the plan terms.
Start by sending a photo or describing what’s going on. With a membership you can message a licensed dentist about it. OneOral is designed for most adults and complements — never replaces — your regular in-person checkups.
No. OneOral is not insurance and you don’t need any. Each plan is a flat monthly price, plus sales tax where it applies.
On any plan you can message a licensed dentist and share photos. On OneOral+ and Power Pack, your first box ships once your first payment is made. The Treatment Box (and Power Pack’s mints or spray) then ships every 3 months; Power Pack’s whitening and energy gum ship every 6 months. Shipping is free, to US addresses only.
When clinically appropriate and permitted for your situation, a licensed dentist can send a prescription to your local pharmacy for pickup. Prescriptions are not guaranteed. Pharmacy charges may apply; some concerns require in-person dental treatment.
