Patients have developed sore jaws or had difficulties opening their mouths after consuming giant burgers, the China Post quoted professor Hsu Ming-lung of the School of Dentistry at National Yang-Ming University as saying.

Problems can arise when fast-food fans tuck into hamburgers larger than (three inches) high, Hsu said. A human mouth is designed to gape over objects measuring only up to four centimetres.
