When it comes to straightening of teeth we are not limited to those metallic braces and a painful process anymore. All thanks to the Invisalign aligners, made from transparent thermoplastic. They are removable and invisible which makes it the most popular choice among adults these days. In invisalign treatment the tray is removed and replaced with a new one every second week with small movement of teeth and the process continues until the results that you are seeking are achieved. However, for the best results one use them properly and should take care while treatment as the treatment doesn’t end with the fitting of tray.
