What's it take to make it in Hollywood? Looking at these celebs, one might say a beaming smile! Hollywood always leads beauty trends, and has made whiter-than-white teeth a popular norm, but the addition of healthy gums, straight teeth and a positive attitude help these celebs top our "Best Smiles" list. From a biological perspective, shiny teeth and healthy gums indicate a healthy potential mate that will pass good genes on to your offspring. From an aesthetic perspective, who doesn't love a beautiful smile? If you know that you're looking and feeling your best when you have a laugh with friends, it can up your confidence in so many ways. However, if you're feeling not so great about your own smile, you may be hesitant to laugh it up with your pals. If you think your smile is in need of an update, call your local medical professional to find your options out! A nice smile is easier to obtain if you take the right steps: brush, floss, and go easy on the coffee, and you too can be smiling like the stars!
