How long would it take for a 1 mm wide gap between the front teeth to close if teeth bands were used?

Compressor bands such as "Teeth Effects" are used to draw your teeth together. They provide "the pull" necessary to move the teeth quickly, and in the right direction. You stretch the teeth effect band when you put it around your teeth. Since the band is stretched out, it pulls the teeth towards one another because it wants to contract. It should close in several days.

*Always consult your dentist or orthodontist -- changing your bite can affect those teeth and the teeth around it.
