Researchers led by Dr Nathan Watemberg at Meir Medical Center in Israel suggest that teenagers who regularly chew gum often give themselves headaches.
Dr Watemberg revealed that he noticed a large number of teenagers who visited the center with complaints of headaches were regular gum chewers, with girls more likely to be avid chewers compared to boys.
A number of studies have shown that regularly chewing gum damages the temporomandibular joint, or TMJ, leading to unnecessary wear and tear of the cartilage which acts as a shock absorbent in the jaw joints. Dr Watemberg said that four in five teenagers who quit chewing gum admitted experiencing relief from their headaches.
