The professor on that show told G.NA that she may have Temporomandibular Disorder (TMD). It is a problem with the jaw, jaw joint, and surrounding facial muscles that control the movement of the jaw and chewing. The professor said that the molars of G.NA were not good resulting to an improper chewing which gives more pressure than normal on her jaw.

It was not the first time that G.NA was warned about her health. On G.NA's past appearance on the same show, she was reminded to be cautious for she was being too much underweight.
