This Tongue Can Show You The World!
Well here’s a new one for ya, Geographic Tongues. Geographic tongue is a completely benign condition that leaves patterns and shapes on ones tongues in whitish and red colors often in the shape of geographic landmarks. Even though there’s no treatment, the strange-looking patterns that appear will disappear and migrate over night. Few studies have been done on geographic tongue. However, a 1976 study in an oral health journal does suggest it’s hereditary and is prevalent in about 2% of the population.
