Top 10 Most Commonly Asked Invisalign Questions


A 2013 study by the American Association of Orthodontists reported that 75% of adults surveyed found an improvement in career standing or growth in personal relationships post orthodontics. They attribute this improvement to an enhanced smile. With Invisalign®, aligning your teeth is easier than ever, and our doctors at North Idaho Dental Group have compiled a list of the most commonly asked Invisalign questions.  


What is Invisalign®?  

Invisalign is way for dentists and orthodontists to move teeth using custom fit, clear aligners.  It works by applying slight, constant force in just the right direction to move teeth to an ideal position.  

What are Invisalign aligners made of?

Invisalign aligners are made of clear flexible plastic that are free from harmful chemicals like BPA.  

What is the general process for receiving Invisalign?  

Before starting Invisalign, our patients receive a thorough comprehensive evaluation of their teeth.  We start by taking a 3-dimensional scan of your mouth. The scan is then sent to Invisalign and your dentist will work with the Invisalign software to create a treatment plan custom to your needs.      After the trays are made, you return to our office to have them delivered. Often times treatment will involve the placement of small resin attachments on your teeth that are removed after treatment. These resin attachments are shade-matched to your teeth and help enhance our ability to move teeth as quickly as possible.   After the trays are delivered to you, you generally wear the same aligner for 1 to 2 weeks, and per your dentists’ instructions, switch to the next aligner accordingly. This process repeats and every week, your teeth move from where they once were to a more ideal position.  

How long do you have to wear them each day? 

Invisalign retainers should be worn for 22-23 hours per day.  They should only be taken out for eating and routine oral hygiene practices.  On special occasions they can be taken out for longer, but keeping them in for 23 hours a day will allow for quick, predictable tooth movement.  

How long does treatment last?  

Invisalign treatment can range from as little as 3 months to 1-2 years.  Most of our patients are in treatment for 6 to 8 months. 

Can Invisalign be done on older patients?

Absolutely!  The principles that make Invisalign so incredible can be applied to patients at every stage of life.  As we age, however, teeth sometimes can move less quickly so treatment can take longer.  

Is Invisalign treatment more or less expensive than traditional orthodontics?

While cost can vary based on complexity and length of anticipated treatment, Invisalign is generally around the same cost as conventional orthodontics. 


Do dental insurances cover invisalign?  

Many insurance plans today have orthodontic coverage.  Our front office staff here at North Idaho Dental group would be happy to help investigate your specific benefits further.  

What if I’ve had braces in the past, or other dental treatment? 

Many of our Invisalign patients are adults that had orthodontics as teenagers and their teeth have relapsed to a pre-orthodontic state.  Invisalign is a fantastic treatment option for those patients regardless of previous treatment. Many of our Invisalign patients have also other dental treatment in the past, from fillings to implants and crowns.  Though not always ideal, we certainly can work around many of these issues with thoughtful and well crafted treatment plans.  

Does Invisalign treatment hurt?  

Invisalign works by gently applying a constant pressure to your teeth.  Patients will generally say that they experience slight discomfort for 2-3 days following insertion of a new tray, then things calm down.  The pressure is completely normal and is a sign that the Invisalign is working!

It’s good to know that I would have to wear Invisalign 22-23 hours every single day and should only take it out for eating and regular oral hygiene practices. I have always been insecure about crooked teeth, but my parents cannot afford to get me braces during my younger years. Now that I’m an adult, I’m planning to get an Invisalign for my misaligned teeth. Thanks for the information!
