A tooth meridian chart, also called a tooth organ chart, links each tooth to an organ, body system and, in some versions, an emotion. It's popular in holistic and biological dentistry and often comes up when someone has a tooth problem that seems connected to how they feel elsewhere.
This guide gives you a clear chart, explains where it comes from, and is honest about what science does and doesn't support, including the mouth-body links that are well established.
In short: the tooth meridian chart comes from traditional Chinese medicine and was developed into its modern form by German physician Reinhold Voll in the mid-20th century. There's no scientific evidence that individual teeth are connected to specific organs through meridians. But there is solid evidence that gum health and whole-body health are connected, and some tooth pain really can come from elsewhere in the body.

The tooth meridian chart
Charts vary slightly between sources, but most follow the same pattern. Tooth numbers below use the US Universal system: 1 is your upper right wisdom tooth, 16 is upper left, 17 is lower left and 32 is lower right.
| Teeth | Tooth numbers | Linked organs (meridians) | Traditional emotion |
|---|---|---|---|
| Incisors (front teeth), upper and lower | 7–10, 23–26 | Kidneys, bladder | Fear |
| Canines (eye teeth), upper and lower | 6, 11, 22, 27 | Liver, gallbladder | Anger |
| Upper premolars | 4, 5, 12, 13 | Lungs, large intestine | Grief |
| Lower premolars | 20, 21, 28, 29 | Stomach, spleen and pancreas | Worry |
| Upper first and second molars | 2, 3, 14, 15 | Stomach, spleen and pancreas | Worry |
| Lower first and second molars | 18, 19, 30, 31 | Lungs, large intestine | Grief |
| Wisdom teeth, upper and lower | 1, 16, 17, 32 | Heart, small intestine | Joy, overexcitement |
Many charts also link teeth to joints, glands, vertebrae and sense organs. Those extra links differ much more between versions.

Where the tooth meridian chart comes from
Traditional Chinese medicine describes meridians as channels through which the body's energy, or qi, flows, each associated with an organ. In the 1950s, Reinhold Voll, a German physician, combined these ideas with electrical skin measurements in a practice called electroacupuncture according to Voll. He and his colleagues mapped teeth onto the meridians, producing the chart most people see today.
The chart was later adopted by some holistic and biological dentists, who use it as one way to think about the whole patient rather than treating a tooth in isolation.
Tooth meridian chart and emotions
The emotion column comes from traditional Chinese medicine, where each organ system is associated with an emotion: the kidneys with fear, the liver with anger, the lungs with grief, the spleen and stomach with worry and the heart with joy. Some practitioners read tooth problems through this lens, for example linking front-tooth trouble with fear or stress.
There's no research showing a specific emotion affects a specific tooth. What is well documented is that stress affects the whole mouth: it's linked to teeth clenching and grinding, cracked teeth, jaw pain, canker sores and more gum inflammation. If you notice dental trouble during stressful periods, that connection is real, even if it doesn't follow the chart.

What science says about tooth meridians
Scientists haven't found anatomical structures matching meridians, and there are no controlled studies showing that a problem in a particular tooth predicts disease in its "linked" organ. Electroacupuncture devices haven't held up well in testing either. So the chart is best understood as a traditional framework, not a diagnostic map.
It's worth being careful about one thing in particular: don't remove or treat a healthy tooth because of the chart, and don't skip medical care for an organ concern because a tooth seems fine. Decisions like these should come from a proper exam.
Real connections between teeth and the body
Even without meridians, your mouth and body are connected in ways that are well supported:
- Gum disease and chronic disease. Periodontitis is associated with heart disease, diabetes, pregnancy complications and more. Diabetes and gum disease affect each other in both directions. We explain these links in the oral microbiome and whole-body health.
- Referred pain. Pain isn't always where the problem is. A sinus infection often feels like an ache in the upper back teeth. Jaw muscle tension can feel like toothache. And jaw pain can, rarely, be a sign of a heart attack, especially with chest discomfort, shortness of breath or sweating; that's an emergency.
- The mouth as an early warning system. Dentists sometimes spot signs of diabetes, acid reflux (from enamel erosion on the back teeth), eating disorders, nutrient deficiencies and other conditions first.
- Infection can spread. A tooth abscess left untreated can spread to the jaw, face and beyond.
How to use the chart sensibly
- Use it as a prompt, not a diagnosis. If a tooth problem and a health concern seem connected, mention both to your dentist and doctor.
- Get the tooth properly checked. Pain, sensitivity or swelling needs an exam and, often, an X-ray.
- Look after the basics. Healthy gums are the most proven way your mouth supports your whole body.
- Consider a biological or holistic dentist if you like a whole-body approach. Choose one who also follows evidence-based care.

Frequently asked questions
What is a tooth meridian chart?
It's a chart from traditional Chinese medicine and Reinhold Voll's work that links each tooth to an organ, body system and emotion through energy pathways called meridians.
Which tooth is connected to the heart?
In most tooth meridian charts, the wisdom teeth are linked to the heart and small intestine.
Which teeth are connected to the kidneys?
The incisors, your four upper and four lower front teeth, are linked to the kidneys and bladder.
Which teeth are linked to the stomach?
The upper molars and lower premolars are linked to the stomach, spleen and pancreas.
Is the tooth meridian chart real?
It's a real traditional concept, but there's no scientific evidence that individual teeth are connected to specific organs. Connections between gum health and overall health are well supported.
Can a bad tooth make you sick?
Yes. An untreated infection can spread, and gum disease is associated with several chronic conditions. See a dentist for pain, swelling or a bad taste that won't go away.
What is the difference between a tooth meridian chart and a tooth organ chart?
They're two names for the same thing. You may also see "dental meridian chart" or "meridian tooth chart."
