Clear teeth aligners are transparent trays made of special material which are used to straighten teeth just like braces. They use gentle and constant force to move the teeth in the required position without going through the hassles of metal wires and brackets. They are custom made for each patient through a digital scan.
They are designed to move teeth in the desired direction very very slowly. This is achieved by digitally capturing impression and processing the information using specialized software, where the future projections for better results and straighter teeth are computed and then the milling machine automatically custom fabricates the set of trays for you. On average, a person needs approximately 25-40 sets for complete alignment. The aligners come with an advantage i.e. they are very snugly fitting which over a period becomes virtually a part of the body and hence causes no speech problems. There are no restrictions on eating and drinking any foods as you will be removing them before every meal.
If you are looking for a discreet, quick, and convenient way to straighten your teeth, clear aligners are the ideal option. Clear aligners cost anywhere between $1200 and $8000. They tend to be faster than braces because the trays are customized during the course of treatment. Every few weeks, you will come back into the office to have new aligners made just for you. These aligners change during treatment so that they are always working to improve the look of your teeth.
