Invisalign straightens your teeth the same way traditional metal braces do but they’re much more comfortable and almost invisible. An orthodontist will work with you to come up with a treatment plan that usually lasts 6-18 months. You wear clear aligners, that are replaced every two weeks, over your teeth. You can eat and sleep in them but the best part is that you can take them out for brushing or a hot date. It is recommended that you wear the aligners for 20-22 hours a day to get the quickest results. Invisalign costs about the same as braces, about $3500-$5,000 and most dental insurance will cover part of the expense.
