The symptoms of an orange tongue are fairly simple and easy to detect. The most obvious is an orange discoloration of the tongue that has a stronger orange color closer to the back of the tongue and throat area. Other symptoms that accompany the orange color are a possibly dry tongue or an odd, unpleasant taste in the mouth. If this orange can be brushed off and does not return without eating orange colored food and you aren’t experiencing a foul taste or dryness that is not solved by hydrating and brushing your teeth, it is most likely temporary and related to something that was eaten. If the orange color returns with or without any of the accompanying symptoms, then you are most likely suffering from orange tongue.
