With the use of clear, removable aligners, Invisalign is a contemporary orthodontic treatment that straightens teeth and treats dental problems. These almost invisible, custom-made aligners provide a discrete and comfortable alternative for straightening teeth. Every few weeks, a new set of aligners is used to gradually realign the teeth during the treatment process. One benefit of Invisalign is that it makes dental hygiene easier by allowing you to take out the aligners when brushing or eating.
