Invisalign takes a modern approach to straightening your teeth. Custom made clear aligners are processed for a comfortable fit to your teeth only. These aligners are made of plastic that is smooth, very comfortable, and barely recognizable to others. You will wear the aligners and this will gradually shift your teeth into alignment. The great thing about invisalign is there is no metal brackets or wires to tighten. Every two weeks you will simply wear a new set of clear aligners until the desired result is achieved, and most people won't even know you are straightening your teeth.
