Well, technically speaking, dimples are a birth defect. Cheek dimples are thought to be formed by divides in a facial muscle called the zygomaticus major. Although they are a genetic defect, dimples have no effect on the body, other than making you look cute.

Also, dimples don't always form in pairs, many people will have a dimple on one cheek but not the other!
