A good smile can brighten up the room. People who frequently smile are perceived to be more in control, at ease and attractive than those who don't (Lau, 1982). However, a genuine smile may do more than just improve your appearance. New research has found a strong connection between smiling and your general health and well-being. So, if you are reluctant to smile due to self consciousness or embarrassment over your smile, it can be hurting more than social life. It may be affecting your overall well being.
