One of the major factors that so many patients love about Invisalign is that they’re incredibly comfortable by design. Remember that at the beginning of the process, a series of sophisticated scans and images are taken of your teeth – which includes their precise shape and measurements. Because of that, each aligner tray essentially acts as a “second set of skin” for your teeth. There are no uncomfortable metal brackets and wires to deal with and most people quickly forget they’re wearing them at all.
