  • 3. Cracked or Fissured Tongue

    Possible Cause: Fissured Tongue or Geographic Tongue

    A 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.
