Invisalign is a process where clear plastic removable aligners move your teeth in small increments to gradually straighten and align your teeth. It is an alternative to traditional metal braces. These clear aligners are custom-made just for your teeth. These aligners are virtually invisible and fit snugly over your teeth. Each aligner gently shifts your teeth, moving them horizontally, vertically, and even rotating them as needed. As you progress to the next set of aligners, your teeth gradually move into their desired positions, following a personalized treatment plan designed by your doctor.
