We’re total suckers for a man - or a woman - with a winning smile.
You know it when you see it, the kind of smile that’s so inviting it can make you feel good, or instantly turn your own frown upside down on a bad day.
Not all of these TV characters' smiles require stereotypically lips or perfect teeth (although those attributes don't hurt) in order to be considered sexy.
There is no blueprint, except that when these men grin from ear to ear, women all over just melt, and when the women follow suit, men's knees buckle.
Here is our list of the 33 sexiest smiles on TV today ...
Kristen Vangsness as Penelope Garcia -- Criminal Minds
We're all thankful to have a character like Penelope who can easily bright up an episode with her smile and make us forget about all the death, depression and torture going on.
Sophia Bush as Erin Lindsay -- Chicago P.D. - Chicago PD
There isn't a lot of smiling going on, but when we do get a smile out of one of the characters, Erin wins every time. She has this charismatic smile which gives you hope.
Charles Michael Davis as Marcel Gerard -- The Originals
Just look at him and his devilish smile and tell me you wouldn't give him control of New Orleans.
Connie Britton as Rayna Jaymes -- Nashville
You can't be called the reigning queen of country and not have a drop dead gorgeous smile...and beautiful voice to match.
Johnny Galecki as Dr. Leonard Hofstadter -- Big Bang Theory - The Big Bang Theory
It's not a total shocker that a man with a smile like Leonard's would finally score a woman like Penny.
Daniela Ruah as Kensi Blye -- NCIS: LA - NCIS: Los Angeles
No wonder Deeks was so enamored with the gorgeous Kensi. Not only is she beautiful and intelligent, but her smile can light up a room.
