So reports today's Korea Times.
Wonkwang University will open up a Smile Clinic in August. The facility will develop a program that will help find the best-fitting smile for individuals, said Dong Jin-keun, a professor in the dentistry school of the southwestern Iksan-based university.
``In ancient times, a good smile gave off an image of self-confidence and made others feel comfortable, securing a high social status for the family,'' Dong said. ``It is an expression of a person's confidence and consideration, so don't use it sparingly,'' the professor said.
Practicing smiling can lead to visible improvements, with as little as three minutes in front of a mirror every morning being effective. Practicing both small and big smiles are recommended, Dong said.
