Big burgers 'should be dropped' as risk to jaw, warn Taiwan's dentists

Taiwanese dentists have urged fast food chains to drop over-sized burgers from their menus following a growing number of jaw injury cases.

Patients have developed sore jaws or had difficulties opening their mouths after consuming giant burgers, said Professor Hsu Ming-lun of the School of Dentistry at National Yang-Ming University in Taiwan.



Problems can arise when fast-food fans tuck into hamburgers larger than three inches high, Mr Hsu said, according to the China Post.
 
A human mouth is designed to gape over objects measuring up to one-and-a-half inches, the professor said. Overextending can hurt the joint between the jawbone and the temporal bone in front of the ears, he said.
