The Invisalign treatment involves a series of numbered trays developed from an accurate mould of your top and bottom jaw. Over a set period of weeks, each tray of your Invisalign treatment will adjust the teeth position progressively. This adjustment process is mapped out by your orthodontist during the initial consultation stage before treatment and is specific to your teeth alignment requirements. Each tray is fit snugly on the teeth, causing them to gradually shift from their current position and straightening them over time. Each tray is worn approximately two weeks before using the next set of trays prescribed by your orthodontist.
