What is Invisalign®?
The Invisalign® system is the virtually invisible way to straighten teeth and achieve the smile you’ve always dreamed of. Using advanced 3-D computer-imaging technology, Invisalign depicts your complete treatment plan, from the initial position of your teeth to the final desired position. Then a series of clear aligners are custom-made for your teeth – and your teeth only – to move them little by little. Each aligner is worn for about two weeks before being replaced by the next in the series, until the final position of your teeth is achieved. Your Invisalign treatment time will be determined based on your specific needs.
What are the primary benefits of Invisalign?
Invisalign aligners are practically clear. No one may even notice that you’re wearing these virtually invisible braces, 
making Invisalign a seamless fit with your lifestyle and day-to-day interactions with others.
Invisalign is removable. Unlike braces, you have the flexibility to eat and drink what you want during treatment by simply removing the aligners. And you can also remove the aligners to brush and floss as you normally would for fresh breath and good oral hygiene.
Unlike braces, there are no metal brackets or wires with the Invisalign system that could cause irritation to your mouth. Plus since your office visits during treatment don’t involve metal or wire adjustments, you’ll likely spend less time in the doctor’s chair.
And finally, Invisalign allows you to view your virtual results and treatment plan before you start so you can see how your straight teeth will look when your treatment is complete.
How will Invisalign effectively move my teeth?
Like brackets and arch wires are to braces, Invisalign aligners move teeth through the appropriate placement of controlled force on your teeth. The main difference is that Invisalign not only controls forces, but also the timing of the force application. During each stage, only certain teeth are allowed to move. These movements are determined by your doctor as he or she maps out your unique Invisalign treatment plan.
What are aligners made of, and what do they look like?
The virtually invisible aligners, which are made of a thermoplastic material uniquely developed for the Invisalign treatment plan, look similar to tooth-whitening trays. Invisalign aligners are custom-made for you and only you to move your teeth in the sequence determined by your doctor.
Do Invisalign aligners contain Bisphenol-A (BPA)?
No. Invisalign aligners and Vivera Retainers do not contain Bisphenol-A or phthalate plasticizers. These aligners and retainers are made with USP Class VI medical grade, high molecular weight, polyurethane resins. Tests have been conducted to determine the biocompatibility of these materials, and show that they are biocompatible and pass all applicable regulatory requirements and thresholds for human wear in the mouth. Of course, as with any medical device, you should consult with your health professional about your aligner or retainer treatment and any applicable risks of use.
Since having my braces removed, my teeth have shifted. Can Invisalign correct this?
A number of Invisalign patients have undergone a previous treatment involving braces at some point in their past, often during their youth. Invisalign can usually correct the shifting that occurs after braces, and do so without having to go through the trauma and social awkwardness of wearing metal braces.
Will Invisalign treatment be painful?
While Invisalign moves your teeth without the pain and anxiety of metal braces, some people will experience temporary discomfort for a few days at the beginning of each new stage of treatment. This is normal and is typically described as a feeling of pressure. It’s also a sign that Invisalign is working, as it moves your teeth to their final destination. This discomfort typically goes away in a couple of days.
