The next time you’re in a grumpy mood, force yourself to smile. This simple action can raise endorphin levels in your body and trick your brain into thinking your mood has improved! And because smiling is completely under your control, you can use it as a defense against bad moods, feelings of depression and anxiety, and even frustration. Smiling also helps decrease stress levels and support a healthy immune system — so keep your smile bright and your gums healthy by brushing and flossing daily. And the next time you’re wearing a frown, remember that simply turning it upside down will put you in better spirits and maybe even better health!
