A lot of raised fleshy grains at the root of the tongue is a clinical question asked by many patients coming to the dentistry department. In response to this complaint, it is actually most common clinically for patients to misidentify the contour papillae on our normal tongue. Contour papillae are 1 type of our normal tongue papillae. Our normal tongue papillae generally include filiform papillae, fungiform papillae, lobe papillae and contour papillae, while the contour papillae are relatively special in location, they are located at the very back of the tongue, which is what we call the root of the tongue, in front of the herringbone boundary groove, in a herringbone arrangement of a row of tongue papillae, which are much larger than the filiform papillae and fungiform papillae, sometimes up to about 3 mm in diameter, and often have obvious The bulge is often evident. Therefore, in this case, many patients go to the hospital and ask to have the contour papillae examined and diagnosed, which is actually unnecessary, and repeated examination may cause inflammation of the contour papillae and increase the swelling. In general, there is no need to deal with the contour papillae. Patients who are not able to distinguish themselves can check the symmetry of the tongue root elevation, generally symmetrical elevation of the meatus is not a big problem, but if it is unilateral, then it is recommended to go to a professional stomatology department to check whether it is a tumor phenomenon.
