On November 13 (local time), 9now reported that Isaac Johnson, who was recognized by the Guinness World Records in 2022 for being able to open his mouth exceptionally wide, is gaining significant attention on SNS. The size of Isaac's mouth is truly overwhelming. He can fit not only a baseball, but also a soda can, an apple, and even an orange-large and round objects-entirely into his mouth. His videos, shared on the online platform "Hip hub Video," have captivated internet users. Many express both amazement and curiosity, questioning, "Is the human body really capable of this?"

Experts explain that Isaac's extraordinary ability is medically attributed to the exceptional flexibility of the ligaments around his temporomandibular joint (TMJ) and a range of joint motion that surpasses that of ordinary people. Specifically, if the TMJ, located in front of the ear and responsible for complex functions such as speaking and chewing, is more flexible than average, it is possible for the mouth to open this wide.

However, experts warn that if an average person frequently opens their mouth excessively wide, it can put strain on the temporomandibular joint. This may lead to temporomandibular joint disorder. Temporomandibular joint disorder refers to a condition where there is an abnormality in the function of the jaw joint, such as opening the mouth, chewing, or speaking, and it can occur due to damage or imbalance in the complex tissues of the joint, muscles, ligaments, or disc.

If you hear a clicking sound or feel pain in your jaw or in front of your ear every time you open your mouth, or if you experience discomfort when chewing food or speaking, you should suspect temporomandibular joint disorder. Experts advise that to prevent these symptoms, you should avoid suddenly opening your mouth very wide, such as during an exaggerated yawn or by trying to fit large amounts of food in your mouth at once.
