Protruding fleshy bumps on the tongue are 1 disease that many patients come to the hospital dentistry department asking to see. In this case, we must first exclude the contour papillae, because there are many patients who come to the hospital with the problem of contour papillae, which are a row of our normal tongue papillae located in front of the herringbone boundary groove on the back of the tongue, but because of its large size and elevation on the surface of the tongue body, it is especially easy for patients to come to the hospital as a swelling. For the contour papillae, the identification is relatively simple: the patient extends the tongue and looks at a row of papillae in front of the dorsal herringbone sulcus, symmetrical to the left and right, which is the structure of our normal contour papillae. If the patient is not too sensitive to this, then simply checking whether the left and right are symmetrical will be sufficient. In general, most of the raised structures on the tongue that are symmetrical from left to right are normal. However, if the patient extends the tongue and finds that the raised portion of the tongue does not have a counterpart on the opposite side. Then it is indeed possible that a swelling is present. It could be a benign fibroid, but it could also be a malignant adenoid cystic carcinoma, etc. Therefore, if a patient presents with a fleshy bump on one side of the tongue, 1 must visit a hospital dentist as soon as possible.
