Tips for a better Smile

• Opportunities for smiling are all around you. Make the most of them.
• You don't need perfect teeth to have a perfect smile. Not everybody has perfect teeth, and that's okay. Straight teeth are nice, but a great smile doesn't depend on standard model's teeth. That said, if you feel uncomfortable about your teeth you may be reluctant to smile, and that's no good. If that's the case, either learn to appreciate your individuality or look into cosmetic dentistry procedures. Or, you could smile with your mouth closed if preferred.
• Wear clothes that smile. Add to your positive body language the color of happiness. Yellow is the color for dependability. A soft yellow is non-threatening and friendly. Warm colors from the yellow family are welcoming. Golds, browns, golden-oranges, are all dependable colors of friendship. Blues are passive and calm colors. In the visual language, soft blues project a serenity and quiet peacefulness. Avoid reds that are come across as aggressive and threatening.
• You've probably heard of "contagious" or "infectious" smiles. There's a reason for this – when you smile, it tends to make others around you smile. Even in the most stressful times, a roomful of smiles can brighten everybody's mood.
• Ever laugh hysterically about something you've just seen? Take that memory but just laugh slightly and now you have a natural pretty smile.
• A lot of men feel uncomfortable about smiling at strangers, especially at other males. If that is the case, then just offer a casual "Hi", or "Hey man!", or "What's goin' on?". It works just as well, and feels less awkward for a lot of guys.
• Try a light smile: don't show as many teeth as you would when you're laughing. It's the best smile for flirting - light and seductive.
• If you have a tooth that pokes out a bit at the side, as many people sometimes do, try to get your lip to go above it so your lip doesn't catch on the tooth when you smile.
• Don't compare yourself to the celebrities you see on TV, in pictures, etc., because they are faking it. Instead, be yourself, be natural, and be genuine. Everybody has a smile waiting to burst out from inside them somewhere!
• Pretend like you're laughing when you're smiling.

Warning 

• A fake smile can make you look phony, nervous, or even dangerous, so don't just try to put on a smile without first practicing or putting yourself in a happy state of mind. You can spot a fake smile from a genuine (or Duchenne) smile – a fake smile is one where the corners of the mouth aren't turned up, or the mouth is solely smiling, with no change at all in the eyes. You'll know it when you see it as you pick up the subtle body language cues that confuse you as to the smiler's intention; and if it's you making the fake smile, check your emotions to know whether or not you mean the smile.

• Try to make sure you don't have spinach or something stuck in your teeth because you'll leave a poor impression. Duck out to the bathroom after a meal and quickly refresh; this is even more important when you know your teeth are prone to catching bits of food.

• There is no scientific study saying how many muscles it takes to smile over frowning. It's probably just better to accept that smiling is worthwhile because the longer term benefits are worth the effort!
