Gateway to HealthOral + gut health, in one connected conversation.

Start here

When you don’t feel like yourself, start looking upstream.

I am a dentist. Eighteen years of looking in mouths taught me that the mouth and the gut are part of the same conversation — and that almost nobody is listening to both at once.

Any of these sound like you?

Tick them or do not — the page reads the same either way. They are listed because most people arrive with three or four of them and assume they are three or four separate problems.

Here is the part nobody told you: those are not six complaints. They can be six readings from one connected system. Your mouth is the top of your digestive tract, your gut is the rest of it, and what lives in one ends up in the other — some of it protecting you, some of it quietly making you ill.

So, plainly, before any of the words get long:

  1. 1What this isLow energy, poor sleep, digestive discomfort and inflammation can have connected drivers — and the mouth and gut are part of the same conversation.
  2. 2What you doChoose testing, guided support, or a self-directed plan built around where you are now.
  3. 3What you get backA clearer picture of what may be shaping how you feel, so you can choose your next step with more confidence.

That is the entire thing. If you stop reading here, you already know what we do.

Now the words, since you will meet them anyway.

Clinicians call the living ecosystem in your mouth the oral microbiome. Our oral test is called Orobiome.

You do not need either of those words to use the test. I am giving them to you here because they are about to turn up on lab paperwork, in the articles further down this page, and in your dentist's mouth — and I would rather you met them from me than from a form.

Oral microbiome
The community of bacteria living in your mouth, and how they are balanced against each other.
Orobiome
Our name for the saliva test that reads that community and tells you which strains you actually have.
Dysbiosis
The wrong bacteria outnumbering the right ones. It is the situation, not a disease you catch.

The mouth is the doorway. Almost everything that gets into you comes through it.

Why start here

When your body feels off, the answer may not be where you expect.

You may be dealing with fatigue, restless sleep, digestive symptoms, brain fog, or inflammation, and still not have a clear explanation. Gateway looks upstream at the oral microbiome, gut lining, and gut microbiome to reveal patterns that single-system approaches can miss.

  • Your mouth is more than the beginning of digestion.

    Gums, breath, cavities — and then everything else.

    The oral microbiome is a living ecosystem. When it is out of balance, it may affect more than your teeth and gums. It can become part of your larger health story.

  • Your gut needs more than another supplement.

    Another supplement, another protocol, the same gut.

    The gut lining and microbiome help shape digestion, immune activity, energy, and resilience. Understanding the context can help you make more informed choices.

  • Stop guessing at what your body needs.

    Guessing, then guessing again.

    Gateway brings oral and gut insight together, then gives you a practical path: testing, guided support, or a structured self-directed system.

Who is telling you this

I have spent eighteen years looking in mouths and finding the rest of the body.

I trained to fix teeth. What I kept running into was patients whose teeth were the least of it — the one with recurring decay who was also exhausted all the time, the one with bleeding gums who was also on her third round of gut protocols and getting nowhere. After enough years you stop filing that under coincidence.

I am not a natural at being a voice on the internet, and I would rather be in clinic. I am doing this because the people who need it are currently being handed either a cleaning or a supplement, and neither of those is an answer to the question they actually asked.

Today I oversee a nationwide network of licensed dentists who read oral microbiome results with people like you, alongside a team of health coaches who help turn what we find into something you can actually do.

Who I work on this with

  • Dr. Pedram Shojai, OMD

    Founder

    Pedram works the other end of the same tube. He directs our gut-health programs, so when a mouth result explains a gut that would not settle, he is the one who takes it from there.

  • Lora Hooper, BSDH, RDH, EFDA

    Oral Health Expert

    Lora has spent her career in the part of this that is hands-on and daily — what actually keeps a mouth in balance between appointments, and what quietly wrecks it.

Reading

Everything here starts from the question, not from the science.

The big line on each one is what people actually ask me. The smaller line under it is what the piece is called, for when you need to find it again.

Not a programme you have to join. Pick the kit for the place you want to start — your mouth, your gut, your sleep, or both ends at once — collect it at home, and then decide what you want to do about what it says. A person reads it with you either way.
