We now have the technology to make your teeth straighter without the use of unsightly metal brackets and wires. Invisalign gradually moves your teeth through a series of custom-made, removable, nearly invisible trays. Straighter teeth are not only a cosmetic treatment, they are also important for your health. When you have crooked teeth, food can get trapped in areas that are very difficult to clean. This can lead to decay, gingivitis, and even bone loss. Visit www.invisalign.com for more details.
