2. Small white tongue patches
While we’re on the topic of weird white patterns on your tongue, keep your eye out for this one. Small white patches on the top or underside of your tongue could mean that something is directly irritating the inside of your mouth. These patches (provided they are painless) are caused by an excess growth of cells on your tongue and are often associated with smokers. If you find yourself within this group, look out! Those patches have a strong chance of developing into cancer. The solution? Stop smoking!
If you’re not a smoker, small white patches on your tongue could simply be due to your teeth rubbing against the surface of your tongue, or perhaps eating too much abrasive food like chips.
