Invisalign are custom-made clear aligners, which are virtually invisible and fit pleasantly over your teeth. With these individual aligners in place, they will slightly shift your teeth horizontally, vertically, and will sometimes rotate. The aligners are formed in a specific manner, to use the right amount of force in the right place at the right time. Usually every week, you change to the next set of aligners, allowing your teeth to gradually move into position, following a treatment plan your doctor custom-made for you. At the initial consultation, the doctor will decide weather Invisalign treatment is what you need. Your doctor will make a custom treatment plan, showing the precise movement of your teeth and how long the treatment will take. When you receive the invisible aligners, it is recommended they are worn 20 to 22 hours a day. Your doctor will instruct you to begin wearing a new set of aligner after a certain period of time. You will definitely be able to see progress in your smile, which will continue for the rest of the treatment.
