Make SMILING A Habit! In addition to stress reduction, according to the Mayo Clinic, other benefits of smiling are an improved immune system, pain relief, and greater personal satisfaction. Also, when we smile, we trick our brain into thinking we are happy. When our brain thinks we are happy, it releases dopamine, the “happy chemical.” #bestorthodontist #bestorthodontistnearme #bestspringvilleorthodontist
