I have a tongue with deep gulleys. It looks so bad that I usually hide it. How can I treat it?

Dear Samali,
The tongue is normally covered with tiny, pinkish-white bumps (papillae), which are actually short, fine, but may be seen as tiny bumps in some people.
For unknown reasons in some people, the tongue may have splits or fissures (scrotal tongue) which are rarely painful. The splits though may run in families are common in people with downs syndrome (Mongols) and may occur together with a geographical tongue where the tongue may hurt especially when one takes a hot dish or something acidic such as an unripe mango.
Whereas a furrowed tongue is scary, it is benign unless it is associated with another medical condition such as downs syndrome which requires addressing on its own.
