A cracked tongue, also known as a fissured tongue, is a common condition characterized by grooves or cracks on the tongue's surface. It's usually harmless, but understanding its potential causes can help address any concerns.
Causes of a Cracked Tongue
While there isn't one definitive cause, several factors may contribute to a cracked tongue:
- Genetics: Older research suggests a possible genetic link, meaning it might run in families. [Source: Medical News Today]
- Age: Cracks tend to deepen with age. [Source: Colgate]
- Smoking: A 2016 study indicated a possible association between smoking and cracked tongues. [Source: Medical News Today]
- Underlying Conditions: In some cases, a cracked tongue can be linked to conditions like geographic tongue or psoriasis. [Source: Cleveland Clinic, Medical News Today]
- Dehydration: While not a direct cause, dehydration can exacerbate existing fissures and make them more noticeable.
It's important to note that a cracked tongue itself is generally benign and doesn't pose a health risk.

Regular tongue brushing is recommended to prevent this. [Source: Healthline]
When to See a Doctor
While usually harmless, consult a doctor or dentist if:
- The cracks are accompanied by pain, bleeding, or other symptoms.
- You experience changes in the appearance or size of the fissures.
- You have other concerning oral health issues.
