What is it that makes this celebrity's smile so lovely and intoxicating? One could simply say that Julia is a pretty woman with beautiful features, an engaging personality, and lots of great-looking teeth! But there's more to it than that.

Take look at the close-ups. Julia's teeth are of course, very even and white. Their proportions are pleasing to the eye, their shape is feminine (curved edges and rounded corners, nothing too sharp or square), and they aren't too large or too small for her face. Julia's gums are nicely shaped and healthy, and she never shows too much of her gums when she smiles.

Julia's lips make the perfect frame. No matter how widely she smiles, her lips part to show both upper and lower teeth; and her smile is so wide that you never see less than 12 teeth across the top row, sometimes as many as 14! That's quite a lot, considering that the average is more like 8 to 10. So when Julia Roberts laughs or smiles, she shows teeth from corner to corner and top to bottom.

Finally, looking at her whole face, everything stays in proportion. While some people with broad smiles and lots of teeth can look "horsey", you never get the sense that Julia Robert's mouth is too big or that she's all teeth and jaws.
