Invisalign and Invisalign Teen are comfortable, convenient ways to correct mild-to-moderate orthodontic concerns. Clear, removable, custom-made trays are worn over the teeth instead of traditional metal brackets and wires. Simply wear your aligners all day and take them out for meals and oral hygiene. About every 2 weeks, replace your aligners with the next set to progress your tooth movement. Most of our Invisalign and Invisalign Teen patients complete their treatment in 12-24 months, while some finish even faster.
