Many people have small gaps in between their teeth that they would like fixed. Most people think that expensive braces or crowns are the only answer so they choose to do nothing.
This is not the case. Cosmetic bonding is a procedure where white (color chosen to match your teeth) filling material is placed on the side of each tooth where the gap exists. This closes the gap and makes a rather unaesthetic spot a whole lot better. You can still floss the area, no one can tell that anything has been done, and best of all it doesn't cost an arm and a leg to get it done.
