To create clear aligners for your mouth, your dentist will make a 3-D scan or impression of your teeth, then several sets of aligners will be made according to your custom treatment plan. Your dentist will determine how many sets of invisible aligners you’ll require to address your dental issues.
Once your aligners are ready, tiny, tooth-colored attachments are temporarily bonded onto specific teeth to hold the aligners in place as they move the teeth. The attachments are barely visible when you smile, and most patients quickly get used to them.
Depending on the orthodontic treatment you require, your dentist may also recommend using small elastics to help move the teeth into position. These elastics are held in place by tiny hooks, which are also temporarily bonded onto teeth in places where they don’t interfere with chewing and where they usually aren’t noticeable.
Once each aligner has accomplished its task of incremental tooth movement, you’ll replace it with the next aligner, usually every couple of weeks.
Treatment time with clear aligners is based on how much the teeth need to be moved. The more your bite is misaligned or the more crooked your teeth, the longer it will take. Typical treatment time is between 10 and 24 months — but if you’re an adult who had braces as a child and your teeth have only shifted slightly over the years, you may need aligners for as little as a few months.
