The most common clinical condition is a cyst of the sublingual gland, which is a retention cyst of a small salivary gland in the oral cavity, a small saliva-secreting gland that does not secrete saliva normally into the oral cavity, resulting in local retention. In this case, surgical treatment is required to remove the cyst along with the sublingual gland, as this cyst is prone to recurrence, which is the most common case. It is also possible to have a benign swelling or papilloma under the tongue, which requires surgical removal and pathology to determine the type of pathology. Therefore, if something grows under the tip of the tongue, you should go to a regular dental hospital for examination and treatment.
