Invisalign is a type of teeth-straightening system for adults and teens that involves removable, clear aligners. The team at Pastel Dental develops a treatment plan that includes about 24 custom-fitted sets of aligners that fit tightly over your teeth. You receive specific instructions on when to switch out your aligners, although the average time is every one to two weeks. A typical course of treatment with Invisalign lasts 12-18 months.* One of the major benefits of this aligner system is that you can remove them to eat, drink, and clean your teeth. Of course, for many people, the fact that they’re almost invisible is a major plus, too. In fact, most people won’t know you’re wearing braces unless you tell them. Invisalign can fix overcrowding, crooked teeth, and gapped teeth, as well as several kinds of bite issues, such as overbite, underbite, open bite, and crossbite.
