Smiles don’t just light up your face, they release feel-good neurotransmitters like dopamine, endorphins and serotonin. This not only relaxes your body, but it can also lower your heart rate and blood pressure. So, yes, it’s a fact, the act of smiling activates neural messaging that benefits your health and happiness. According to the American Academy of Cosmetic Dentistry, 99.7% of the population perceives “smile” as an important social asset and those who have a good smile are believed to possess positive attributes that make them look more beautiful, successful, smarter, happier, interesting, wealthy, and more appealing.
The question is why don’t people smile more often? They know it feels good and they see it makes other people happy but what they show is the thin line of tightened lips where there should be a big broad smile. Apart from reasons that are not treated by a dentist, such as depression, the main reason is unease about the look of their smile. And one of the most cited reasons for that, is teeth that look discoloured or stained. That’s why teeth whitening is one of the most searched for terms in Google.
