Simple gestures can have a profound impact, especially the smile. Smiling indicates that you're experiencing positive emotions, or at least that you want someone to think that. A real smile doesn't just involve the muscles around the mouth. The orbicularis oculi muscles around the eyes only activate when genuine emotion triggers the smile reflex. However, many people develop a habit of smiling without revealing their teeth at all. This can reduce the positive impact of the smile, especially on others. Going to a cosmetic dentist in Scottsdale can improve your smile to the point where you feel comfortable sharing it again. Improving your self-esteem with a smile makeover could have a number of positive effects on your life and on others.
