Crooked teeth are usually the result of the improper developments of the jaws due to the combination of genetics and environmental factors. There are few ways to align the teeth and the most common way is the use of braces and Invisalign. Invisalign involves a series of clear aligners which will be worn and replaced weekly. They are made based on smart technology and are very aesthetic compared to traditional braces.
The most important factor beside the straightening the teeth is to make sure the bite ( how the upper and lower teeth coming together ) is correct and stable. Unfortunately many dentist and orthodontist only focus on how the end result looks like as opposed to how stable it is. We use itero 3D scanner to get the most accurate digital impression and avoid any error. It also helps people who gag on impression materials.
