Damage to the lingual nerve can lead to atrophy of the fungiform papillae on the tongue. The lingual nerve is primarily responsible for sensory innervation, including taste, to the anterior two-thirds of the tongue and sensation to the floor of the mouth. When this nerve is compromised, the normal functioning and innervation of the taste buds located on the fungiform papillae can be disrupted, potentially leading to their atrophy due to lack of stimulation and sensory input.

Atrophy of these papillae can manifest as a diminished ability to taste and may also impact the overall appearance and texture of the tongue, which can further affect the individual's eating experience and sensation. It is important to recognize that the lingual nerve does not innervate the posterior one-third of the tongue, where taste sensation is instead provided by the glossopharyngeal nerve, which explains why the loss of taste in that area is not a consequence of lingual nerve damage.
