Invisalign® is an orthodontic aligner device that are a series of custom made retainers that you wear over your teeth. They are typically used for patients who have mild or moderately crowded or spaced teeth. There are several sets of clear aligners that make slight adjustments to move your teeth over the time of treatment. They are made of a clear plastic material and fit tightly over the teeth. They can be removed for eating, brushing, and flossing. There are no metal brackets involved and as they are removable it is easier to brush and floss well. They are less intrusive than traditional metal braces and many people will not know that you are straightening your teeth.
