What Your Tongue Can Tell You About Your Health: 4 Symptoms You Shouldn’t Ignore

3. Cracked or Fissured Tongue

Possible Cause: Fissured Tongue or Geographic Tongue

fissured tongue presents with deep grooves, often resembling cracks across the surface. It may be inherited or associated with conditions such as psoriasis or Down syndrome. A related condition, geographic tongue, displays irregular patches that change over time.

Common Causes:

  • Genetics (runs in families)

  • Nutritional deficiencies

  • Dehydration

  • Skin conditions like psoriasis or lichen planus

Symptoms:

  • Visible cracks or deep grooves on the tongue

  • Typically painless unless debris or food particles become trapped

  • “Map-like” appearance in geographic tongue

Prevention and Home Care:

  • Use a soft toothbrush to gently clean the tongue and remove trapped particles

  • Drink plenty of water to stay hydrated

  • Avoid spicy, acidic, or salty foods if discomfort occurs

Generally, a fissured tongue is harmless and doesn’t require medical treatment unless accompanied by pain or secondary infections.
