What Your Mouth Could Be Telling You About the Rest of Your Body

Is your oral microbiome the secret key to overall longevity?

If your mouth could talk, what do you think it would tell you about the rest of your body?

Sit with me for a second. Imagine you're driving along in a beautiful car, maybe the kind you spent way too much money on and suddenly, a red warning light pops up on the dashboard.

What do you do?

Do you: A – Keep driving and, when you get home, slap some masking tape over the flashing red light, hoping it'll magically go away? – Or do you: B – Take it to a garage and ask them to investigate what's really going on?

If you answered "I'd take it to a garage," congratulations, you value the car, and you don't mask. As you know, a red light is a warning sign and means that something or a few things are wrong with the vehicle.

Now, ask yourself: When your body flashes a red warning light in the mouth, do you treat your body the same way?


Your Mouth

If your gums are bleeding, or you notice blood when you spit while brushing your teeth, or your dentist tells you that you have gum disease or loose teeth (not the baby ones, your adult teeth), do you ignore it and mask it with a sensitive toothpaste, harsh alcohol mouthwash and hope it goes away? Or do you ask someone to investigate and treat the underlying cause?


Bleeding Gums: What Could Be Going On?


I always say to my clients who come to me for help: "Test, Don't Guess". Once you know what's happening in the blood that is feeding and supporting the optimisation of the body, you can create a targeted treatment that actually works.

Testing your nutrient levels is now easier than ever. You can order at-home tests through services such as Wellness Platforms, Pharmacies and In-House Wellness Clinics or similar and get results quickly. Some platforms can supply a nurse to come and take blood from your home or workplace at a cost. Once you know where you're low, you can take a targeted approach to bring your levels back to optimal with your medical team.

For B12 and folate deficiencies, which often show up as painful gum issues, the quickest way to restore levels is through a B12 injection, something your GP can provide if your deficiency is deemed significant.


Diet First: Food Is Medicine

Of course, supplementation isn't the only answer. You also need a nutrient-dense diet to support the strength and health of your oral environment. Ask yourself: is your diet helping your body thrive or just survive?

  • Vitamin C – probably the most common deficiency linked to gum issues, not just found in citrus fruits but also in dark greens such as broccoli and Brussels sprouts, potatoes and peas
  • Vitamin D – essential for bone and oral health, it's not just a mood boost vitamin
  • Vitamin K – supports clotting and gum healing, look for a Vitamin D supplement that includes Vitamin K
  • B vitamins – especially B12 and folate, dark leafy greens again, think: green is go
  • Calcium – crucial for strong teeth, for the non-dairy crew, look at kale, broccoli, bok choy, nuts, and chia seeds
  • Iron – deficiency can contribute to gum and mouth problems; look at lentils, chickpeas, tofu, tempeh, pumpkin seeds, sesame seeds/tahini, cashews, dark leafy greens (kale, spinach)

Eating a rainbow of vegetables and fruits helps not just your mouth but your whole body. That's right: your gums and teeth can be and often are a pre-warning light for your overall health.

I learned this the hard way. Over 20 years ago, I was diagnosed with the autoimmune disease lupus. One of my earliest signs: bad breath, chipped teeth, and bleeding gums. Instead of killing off all my bad and good bacteria with an alcohol-based mouthwash multiple times a day or relying on a sensitive toothpaste, I could have tested my nutrient levels. If I had, I would have had the opportunity years before my diagnosis to support my whole body before it ran on empty and crashed.

The good news: more often than not, your body can replenish, restore balance, and heal – mouth and body alike. Mine did. I went from bleeding gums, sensitive teeth, bad breath, and weak teeth to modelling for a toothpaste billboard campaign.


Small Actions, Big Impact

Next time you notice that little pink in the basin when brushing your teeth, pause for a moment:

  1. Question your diet – what could you add more of to your plate?
  2. Book an appointment with your GP – if they don't know, they can't help you
  3. Test your nutrient levels – are they only just within range?
  4. Take a targeted approach with food, supplements and further medical investigation

We're not here just to survive or endure. We're here to thrive. And it all starts with listening to your mouth – it often has a lot to say.
