Why your toothpaste could help protect your heart
Dec
When you think about heart health, you probably think of exercise, eating well, sleeping enough, and lowering stress. Those are all important.
But there’s something else – something simple – that most people overlook. It’s part of your daily routine. You do it every morning and every night.
Brushing your teeth.
Yes, really. Your toothpaste and your oral care routine can play a surprising role in supporting your heart. The path to a healthier heart starts inside your mouth and it all centers around a tiny but powerful molecule called nitric oxide.
Nitric Oxide: A Small Molecule With a Big Mission
Nitric oxide (NO) may be small, but the job it does in your body is huge.
It helps:
Relax and widen blood vessels
Support healthy blood pressure
Improve circulation
Boost overall heart health
Influence memory, sleep, immunity, and energy
But as we age, our body naturally produces less NO.
That’s not great news… but the good news is this:
Your mouth plays a key role in nitric oxide production.
With the right habits, you can support this process every single day.
How Your Oral Microbiome Helps Produce Nitric Oxide
Your mouth is home to a complex mix of bacteria—your oral microbiome.
This community isn’t something to fight. You actually need it.
Here’s the simple version of what happens:
You eat foods rich in nitrates (like leafy greens, celery, or beets).
The good bacteria on your tongue convert these nitrates into nitrites.
As you swallow, your body turns those nitrites into nitric oxide.
Your oral microbiome is where this process begins.
But for it to work well, the microbiome needs to be healthy and balanced.
Unfortunately, some everyday habits disrupt that balance—without us even realizing it.
3 Habits That Lower Your Nitric Oxide Levels
1. Using Alcohol-Based Mouthwash
These mouthwashes leave your mouth feeling fresh, but they wipe out everything—
including the good bacteria that help produce NO.
Once those microbes are gone, NO production slows down dramatically.
2. Mouth Breathing
Breathing through your mouth (especially while you sleep):
Dries out your mouth
Disrupts the microbiome
Allows harmful bacteria to grow
Bypasses your nose, where some nitric oxide is also produced
Nasal breathing is essential for good oral and heart health.
3. Skipping Oral Microbiome Care
Your oral microbiome thrives when you:
Tongue scrape
Use fluoride-free, microbiome-friendly toothpaste
Avoid antibacterial products
Skipping these steps weakens the very system that starts NO production.
4 Simple Steps to Boost Nitric Oxide (and Support Heart Health)
If you want to support your oral microbiome and give your heart an easy, daily advantage, begin with these four steps:
1. Switch to Microbiome-Friendly Oral Care
Replace alcohol-based mouthwash and harsh toothpaste with gentle, nourishing products.
The RiseWell Mineral Toothpastes, available here, are:
Fluoride-free
Powered by hydroxyapatite
Gentle on the microbiome
Safe to swallow
Designed to support strong enamel and a healthier oral environment
Small swaps like this make a big difference.
2. Breathe Through Your Nose
Nasal breathing naturally increases nitric oxide production.
If mouth breathing is a habit—especially at night—mouth tape can help guide the body back to nasal breathing.
It’s a simple, low-effort trick with real impact.
3. Eat Foods Rich in Nitrates
Support nitric oxide from the inside out by eating:
Spinach
Arugula
Kale
Beets
Celery
Your oral bacteria convert the nitrates in these foods into the building blocks of NO.
4. Move Your Body
Exercise stimulates the release of nitric oxide in your blood vessels.
Walking, yoga, dancing—every bit helps your circulation and boosts your NO levels naturally.
Everyday NO-Boosting Tips You Can Try
Here are a few simple ways to keep your nitric oxide levels healthy:
Add beetroot powder or juice to smoothies for an easy nitrate boost
Stay hydrated so your oral microbiome can function properly
Enjoy dark chocolate (yes!) since it contains flavonoids that support NO production
Even small changes can create big benefits over time.
