Invisalign® uses a series of clear, custom-made aligners to straighten teeth. These aligners are made from a flexible plastic material and are designed to gradually shift your teeth into the desired position. You wear each set of aligners for about one to two weeks, then switch to the next set. They should be worn for about twenty to twenty-two hours a day, only taking them out to eat, drink, brush, or floss. Over time, the gentle pressure applied by the aligners moves your teeth without using brackets or wires, making them a less noticeable and more comfortable alternative to traditional braces. This cutting edge technology is the ideal way to straighten teeth now for kids, teens, and adults.
