According to this study, craniofacial asymmetry was found in all age groups, including fetuses and infants; therefore, it cannot be correlated to chewing habits developed later in life. However, a Korean entertainment show called Sponge showed that children have perfect symmetrical faces, and its guest professional claimed that asymmetry is caused by chewing habits in most cases which can be corrected in about a month by reversing the dominant chewing side. Such an asymmetry occurs because the facial muscles on the dominant side gets stronger and the other collapses. This, for example, can cause one’s eyeglasses to be uneven and one side to slide down more frequently than the other.
Personally, I’m very skeptical — especially after reading that study. But the show was very convincing, and since my eyeglasses is crooked, I’m giving it a try.
