Carl was getting married and did not like the gaps in his teeth. He knew this day would only happen once and he wanted to look his best. He had the gaps filled in and he has been smiling ever since. His wife would say it's because he's married to her, but whatever the reason, Carl can now smile with confidence and not have to worry about the gaps that once made him hesitant to show his teeth.
