A new method of straightening teeth without the aid of traditional braces is called Invisalign. To shift teeth, a set of clear plastic aligners are worn. It’s not new to move teeth with removable aligners. The new component is a computer software that can generate a number of aligners with minor adjustments. For orthodontic cases with mild to severe crowding or spacing, Invisalign is advised. They are simple to use, practically unnoticeable, and comfortable to wear.
