Invisalign is a form of orthodontic treatment, often used to help a patient achieve a beautiful smile. It is usually used by patients who often have mild or moderate misalignment. It can also be used to align one's bite. Anyone with an underbite, crossbite, or overbite will enjoy Invisalign treatment. The process uses clear plastic aligner trays that help the teeth move to proper alignment gradually. You have to wear the trays for at least 20 hours every day. You can easily remove them when you want to floss or brush. You can get your smile back in as little as six months. This procedure is comparable in cost with regular braces. There are multiple ways in which you can make it affordable. You could arrange for a monthly payment, pay with tax-free dollars from your HAS or FSA. Or you could use your insurance coverage.
