To make it in Hollywood, you've got to have talent and determination. You also need good luck and lots of charisma, and that's where a winning smile can shine through. Plenty of A-listeners have had professional help getting their teeth camera-ready. Here are a few stars of the silver screen that have used cosmetic dentistry to turn up the wattage on their million-dollar smiles.

Nicholas Cage

Now a fixture in the 'New Releases' section, Nicholas Cage was not always a leading man. In fact, his very first feature film appearance is credited under a different, although very familiar, name: Nicolas Coppola. Yes, that Coppola. Wanting to be taken seriously as an actor in his own right, he changed his name at the beginning of his career. He gave his career another boost in 1984 when he had four baby teeth removed in preparation for porcelain veneers. By then, he'd gone full Nicolas Cage in name and spirit. He decided to schedule his cosmetic dentistry to align with his role in “Birdy,” as a man who suffices a blow to the face in the Vietnam War.

Miley Cyrus

Back before she was a global pop superstar, Miley Cyrus was a teen idol on the hit Disney Channel show, “Hannah Montana.” On the show, she played a kid who was secretly a global pop superstar. As a youngster, her slightly crooked front teeth were endearing and adorable. But as she got older and gained more exposure, she got a little cosmetic dentistry to boost her confidence in her smile. Now, her beautifully veneered, whitened teeth are seen on magazine covers across the globe.

Jim Carrey

Jim Carrey is a comedy legend who has appeared in over 40 movies. In one of his best movies, “Dumb and Dumber,” he plays Lloyd Christmas. Lloyd is a limo driver who dreams of owning a worm store. Lloyd's trademark chipped-tooth grin is no movie magic; that's Jim Carrey's tooth. Carrey explained in a 1995 interview that when he was a kid, he chipped his tooth in a scrap in grade school detention no less. He had it capped years before he even got into acting, but he decreed the chip would fit his character in “Dumb and Dumber.” Nearly two decades later, he popped the cap back off for the sequel “Dumb and Dumber To.”

Ben Affleck

Ben Affleck is one of Hollywood's most bankable stars of the past 15 years. After Argo, which he directed and produced, he won an Oscar for best picture. Affleck rose to the very top of the A-list, and he occupied the role of Batman in the incoming Justice League franchise. He's come along long way since co-writing “Good Will Hunting” with Matt Damon. His transition from Southie slacker to the caped crusader almost did not happen. Before making “Armageddon,” Director Michael Bay endorsed that Affleck get cosmetic dentistry to play the romantic lead. It's rumored the dental work cost between $ 10- $ 15k. Money well spent, however, as the film went on to gross over $ 550 million at the box office.
