One of the things that prevent patients from undergoing orthodontic treatment is the appearance of metallic structures attached to the teeth by way of metal brackets and a metal wire across the set of teeth. Invisalign is a cosmetic option that can be done to move teeth without placing metal attachments and wires that also make it difficult to maintain the cleanliness of the teeth and gums. It requires wearing clear trays that need to be changed to the next level number every 2-3 weeks and worn at least 22 hours every day depending on how much discomfort the patient can tolerate. Change happens because clear buttons that are directly bonded to the tooth structure assists in moving the teeth towards the preferred direction. The length of treatment will depend on how complex the misalignment is and will take anywhere from 6-24 months.
