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.
Scott Caan as Detective Sergeant Danny Williams -- Hawaii Five-O - Hawaii Five-0
There is just something about Danny's smile which makes me just smile at my TV no matter what the circumstances are.
Lana Parrilla as Regina Mills AKA The Evil Queen -- Once Upon A Time
Many would say Prince Charming has the award winning smile, but in all honesty, Regina has the sexiest smile on the show. Maybe it's the whole bad girl turned relatively good, but her smile can easily win people over.
Misha Collins as Castiel -- Supernatural
Castle may not smile a lot, but when he does, stand back because you won't be able to resist him.
Candice Accola as Caroline Forbes -- The Vampire Diaries
Despite letting go of her humanity and going on a murderous rampage, all Caroline has to do is apologize and give us all an innocent smile and all will gladly be forgiven.
Jesse Williams as Jackson Avery -- Grey's Anatomy
Let's be honest, the entire cast of Grey's Anatomy have pretty sexy smiles, but there's something about Jackson which just makes you swoon. Maybe it's the combination of the good looks and baby blues, but the man is downright sexy.
Ari Stidham as Sylvester Dodd -- Scorpion
Not only did Sylvester's personality and smile catch the eye of Walter's sister Megan, but it also caught the eye of millions of viewers.

Her upbeat outlook on life comes shining through when she gives out one of her beautiful, yet sexy, smiles.
Andrew Leeds as Josh -- Cristela
Many will remember Andrew Leeds as the murdering Pelant from Bones who maintained a creepy smirk throughout his carnage. Times have certainly changed and now we welcome that sweet smile from the lovable character of Josh on Cristela.
Nick Wechsler as Jack Porter -- Revenge
Jack has always been the underdog on Revenge and I've never understood how Emily/Amanda/Whatever her name is, never went after him. He's not only got good looks, but also has a gorgeous smile.
Darby Stanchfield as Abby Whelan -- Scandal
Abby may have been through the wringer a few times, but the woman still maintains a decent outlook on life and a smile which makes you forget all the scandal going on around you.
Janina Gavankar as Detective Meredith Bose -- The Mysteries of Laura
Meredith doesn't smile too often, but when she is geeking out over a new game, she just can't resist revealing a sexy smile. Now if only Billy would read the signs she's been sending him and get the picture, that would be great.
Ross Philips as Tom Long -- Hart of Dixie
So many of the men and women on Hart of Dixie have beautiful smiles, but Tom has always been one I've been attracted to. Not sure it it's his nerdy nature or his bright outlook on life, but his smile can easily make a girl melt.
Emily Rickards as Felicity Smoak -- Arrow
Not only is Felicity intelligent, gorgeous and have a beautiful smile, but she also has the attention of Oliver Queen.

Christina Hendricks as Joan Harris -- Mad Men
You can't deny a woman with a confidant smile is a force to be reckon with and Joan fits the bill.
Julia Louis Dreyfus as Vice President Selina Meyer -- Veep
It's rather shocking Selina can still maintain a rather sexy smile considering everything falling apart around her; though I have no doubt that smile will win her the Presidential office.
Ian Harding as Ezra Fitz -- Pretty Little Liars
When Ezra smiles it just makes things a little better.
Sherri Saum as Lena Adams Foster -- The Fosters
It shouldn't come as a surprise to learn Lena's warm, friendly smile has garnered the unwanted attention of various people.

I know many would go with Sean Renard, but there's something about Monroe's smile that always makes me giddy. He's just an all around great guy with a genuine smile.
Jesse Spencer as Lieutenant Matthew Casey -- Chicago Fire
The entire cast of Chicago Fire could easily be chosen for sexiest smile, but Matthew wins me over every single time. Maybe it's the sexy smile paired with the uniform, but my goodness the man is gorgeous.

It's rare to get a smile out of James, but when it comes out, watch out world because it will melt you to your core.
Joelle Carter as Ava Crowder -- Justified
While I am really going to miss seeing a smile from Raylan Givens, I can't deny Ava had one killer smile too. It's not a surprise men would fight over a sexy woman like Ava.
Bianca Kajlich as Leslie Burton -- Undateable
Leslie may have a fear of never finding a man again, but that smile will definitely help her out.
Jay Ryan as Vincent Keller -- Beauty and The Beast
Even though he's considering a beast, you can't deny he has a drop dead gorgeous smile that could make anyone change their stance on dating a beast.
