#89: Your Tongue is Warning you About Your Health

What Your Tongue Says About Your Health


Secrets Hiding in Plain Sight


Your tongue is one of the most underrated tools in your body’s health toolkit.


Did you know your tongue can reveal early signs of disease, vitamin deficiencies, or oral health issues? Dr. Radwa Saad breaks down 8 tongue clues you need to know.


It can reveal issues with your nutrition, immune system, hydration, and more—*before* you ever feel sick. As a dentist, I check the tongue at every appointment because it often shows me what your body is trying to say.


Here are 8 tongue signs you should never ignore:

1. White Coating

Could mean:

- Oral thrush (yeast/fungal infection)

- Dehydration

- Poor oral hygiene

Common in those on antibiotics, with dry mouth, or diabetes.


2. Bright Red or Smooth Tongue

Often caused by:

- Vitamin B12 or folate deficiency

- Iron deficiency

It may look “bald” if papillae (tiny bumps) are lost. Can also feel sore.


3. Geographic Tongue

Red, map-like patches that move around.

Usually harmless, but can flare with stress, hormones, or spicy foods. If painful, talk to your dentist.


4. Black Hairy Tongue

A buildup of dead skin, bacteria, or yeast that stains the tongue.

Caused by:

- Smoking

- Antibiotics

- Poor oral hygiene

- Excessive coffee/mouthwash


5. Scalloped or Wavy Edges

If your tongue has indentations or “tooth prints,” it might be:

- Swollen from clenching or grinding

- Linked to sleep apnea or airway issues


6. Persistent Ulcers or Sores

Any sore that doesn’t heal in 10–14 days should be checked.

Could be:

- Trauma (biting tongue)

- Autoimmune disease

- Oral cancer (especially if hard or painless)


7. Pale or Purple Tongue

Pale = possible anemia or poor circulation

Purple or bluish = sluggish blood flow, chronic conditions


8. Bad Taste or Metallic Sensation

Could be:

- Infection

- Medication side effect

- Old metal fillings


Tongue Care Tips

- Use a tongue scraper or brush daily

- Stay hydrated

- Eat vitamin-rich foods (especially B12, iron, and zinc)

- Get regular oral cancer screenings


When to See a Dentist

If you notice:

- A sore or patch that doesn't go away

- Changes in color or shape

- Pain or burning
