Geographic Tongue

Have you ever heard of such a thing? I hadn't until a few months ago at Thevy's dentist appointment. Basically, there are patches on the tongue that form geographic shapes. You know how our tongue is covered in bumps, yeah? Well, most of those are taste buds, but the ones that aren't are the ones involved in creating these patterns on the tongue. There are parts of the tongue that are smooth and 'bumpless' surround by areas where the bumps, or papillae, are flared up or overcrowded or something. These patches come and go and are apparently harmless. When we first noticed them in Thevy, we wonder if she hadn't eaten some hot food and burned her tongue.
