What does it mean when your tongue starts cracking? 👅👇
Cracks or grooves on the tongue are often called fissured tongue. It is usually harmless, but it can be linked to some conditions.
Common causes include:
✔️ Dehydration
✔️ Vitamin B deficiency
✔️ Iron deficiency
✔️ Poor oral hygiene
✔️ Aging
✔️ Certain medical conditions
What you should do:
• Drink more water
• Maintain good oral hygiene (brush tongue gently)
• Eat balanced meals rich in vitamins
• See a healthcare professional if it’s painful, swollen, or persistent
Most times, cracked tongue is not serious, but your body may be signaling a nutritional or hydration issue.
Listen to your body.
