Whoever coined the sentence, “A smile lights up the entire face.”, was not joking – it really does! That is why most Hollywood celebrities have their crowns whitened, straightened and even capped to make sure they look their best. They can afford to fork out thousands of dollars for this – it’s their job to be beautiful. I bet celebrity dentist Dr Jonathan Levine is always fully booked with clients.

If you are wondering which celebrities are touted to have best celebrity smiles, look no more as I did my research and here they are.

Top 1 to 10: Jessica Alba, Bridget Moynahan, Gisele Bundchen, Scarlett Johansson, Rebecca Gayheart, Kate Beckinsale, Katherine Heigl, Jennifer Garner, Julia Roberts, Megan Fox

According to a research, Jessica Alba tops the list because her smile is closest to the standards of a good smile called Golden Proportions. Note that even imperfect smiles like those of Rebecca Gayheart are still included (she has her lateral incisor longer than a central incisor).
