Invisalign is an excellent treatment for providing you with the smile of your dreams. The removable aligners can discreetly straighten the teeth of adults and may also be suitable for some older teenagers. On average, treatment generally takes a year to complete during which time you will need to wear your aligners just about all the time. However, once your teeth are beautifully straightened then it’s important that you look after your new smile. Your orthodontic treatment will continue even after your teeth are straight.
