Upon a closer examination of the tongue, your dentist will check the size and texture of the tongue to ensure a healthy mouth. Your tongue's size and the surface can determine a lot about your dental health, as well as your overall health. For tongue lesions such as changes in colour, growths, or texture changes, an oral surgeon or an ENT specialist can evaluate the area, perform a biopsy, and follow up or refer for appropriate treatment such as surgery or medication.
