What Smiles Do For Us

Jan 24 2019

No matter the language we speak, a smile is a universal sign of joy and trustworthiness in terms of non-verbal communication. Getting an authentic, sincere smile may be better than getting cash, a study performed in 2005 claims. According to Dr. David Lewis, the psychologist who evaluated these findings: "The powerful emotions triggered when someone important in our lives smiles at us and we smile back changes our brain chemistry. It creates what is termed a 'halo' effect that helps us remember other happy events more vividly, feel more optimistic, more positive, and more motivated."

In addition, a stress-managing hormone called Brain-Derived Neurotrophic Factor and endorphins are releasing during the physical act of smiling, giving them the ability to lower stress. A genuine smile also conveys sincerity, friendliness and confidence. This is the reason why employers are more likely to hire those who have bright, honest smiles throughout the interview process than candidates who wear forced smiles.

But how do we know if a smile is truthful or not? Most people will be able to spot this distinction when interacting with others. When people force a smile, it normally does not reach the person's eyes and there often is tension in the mouth muscles. A genuine smile is known as a Duchenne smile. This is when our cheeks are pushed up because of the lifting of the corners of our mouth, causing crow's feet to form at the corners of our eyes.

It's fascinating, don't you think? Something as simple as a smile can produce a meaningful impact on our everyday lives. For some, however, smiles don't come easily. Some people may be somewhat reserved in regards to their smiles, such as those who struggle with dental complications, like missing teeth, tooth decay, or other problems. Due to this, they run the risk of being misconstrued as incompetent, mean, and unapproachable regardless of how they really are.

Dr. Sato and his team want all of their patients to feel happy and confident when they’re smiling. If you haven’t, go ahead and schedule your next exam with us.
