An Impeccable Smile: The Key to Confidence, Self-Esteem, and a Positive Attitude

Key Takeaways

  • Your mental, physical, and social health are all connected. When your oral health suffers, it can impact your mental and social health as well, and vice versa.
  • Smiling can reduce stress, improve your mood, and increase your self-esteem. When you flash your pearly whites at others, they will most likely reciprocate which will make them feel good, too! 
  • izzo makes it easy and convenient to maintain a sparkling smile. By helping your teeth stay white and bright, izzo can make you feel unstoppable!


The mind-body connection dictates that your mental, social, and physical health are intertwined. Meaning, an improvement or decline in any one of them can affect the others. Maintaining your smile is a great way to improve your physical and mental health and improve your mood!  


If that weren’t enough, a sparkling smile also has the power to lift the spirits of those around you and give you a radiating sense of self confidence. Both of which — rewarding social interactions and self-esteem — positively influence your overall health. So from a greater clean for your teeth to more confidence in your smile, your oral care actually affects your entire being.


Mental Health and Oral Health

There are a variety of conditions that can affect your mental health. From depression to anxiety, studies show that any type of mental health challenge can be connected to your overall physical health—oral health included.  


Nearly 5% of adults in the United States experience symptoms of depression on a regular basis1. It’s one of the most common mental illnesses in the United States, and it’s closely linked with poor oral health. People who suffer from depression are at higher risk for cavities, and tooth loss2.  


Depression isn’t the exception to the rule. In fact, increased risk for cavities, tooth loss, and erosion are also associated with anxiety, phobias, eating disorders, and more3, 4. Chronic gum disease is even linked to increased risk for Alzheimer’s disease5

There’s a wealth of data detailing this common manifestation of the mind-body connection, which indicates that there needs to be more emphasis on oral care for people who struggle with these disorders.  

Researchers have also amassed a lot of information indicating the opposite: poor oral health can lead to a decline in mental health. Dissatisfaction with your smile’s appearance or low quality dentures may make you feel self conscious. In addition to causing difficulty with speaking and eating, these circumstances are linked to social withdrawal and low self-esteem6



Self-esteem & Your Smile

The way you feel about your teeth has a direct impact on your self-esteem. As a result, many people engage in various oral health treatments to improve the look and feel of their smile. Preventive dental care, whitening, and straightening treatments all help improve the aesthetic appeal of your smile. In fact, studies show that young people with high self esteem brush their teeth and visit their dentist more frequently7!


At-home whitening treatments are one of the most accessible ways to improve how you feel about your smile. People who use whitening methods at home report higher self esteem, quality of life, and satisfaction with their smiles8. Add to that the key role that the color of your teeth play in perceived aesthetics, and it’s clear that an oral care routine that maintains a beautiful, white smile is all but essential for high self-esteem9


Smiling Reduces Stress

Taking care of your mental and oral health can help improve the status of both. When you look your best, you often feel your best as well. Having a bright and healthy smile is one way you can help bolster your self esteem, and in doing so, reduce stress.  

To test out the impact of smiling on a person’s mood, one study measured participants’ affect while completing a difficult task. Researchers instructed half of the participants to smile with chopsticks in their mouths. The other half of the group also had chopsticks in their mouths, but they weren’t given any directions about their facial expressions.  

Researchers found that study participants who smiled (whether they were told to or not) experienced lower stress levels than participants who didn’t10. The next time you’re faced with a difficult situation, try smiling to help reduce stress.


Improve Your Mood With A Smile

It turns out that “fake it ‘till you make it” rings true when it comes to a smile. Flashing your pearly whites, even when you aren’t feeling happy, can improve your mood. Likewise, the inability to frown reduces negative feelings in people who have reduced facial expressions resulting from cosmetic procedures to reduce wrinkles.  

Your facial expressions have a direct impact on your mood. When you smile, your brain releases a flood of feel-good transmitters including dopamine, serotonin, and endorphins. These promote a positive mood, while also lowering your blood pressure and heart rate11. In other words, smiling is good for you.  


Your smile’s mood-boosting effects are even infectious!  People mimic the facial expressions of those around them12. So, if someone reciprocates your smile, they will enjoy the benefits of smiling as well!
