Invisalign and Retainers: Commonly Asked Questions

Posted on: June 5, 2019

Clear aligners like Invisalign offer an alternative way to straighten the teeth and fix bite problems without the use of the metal brackets and wires that come with traditional braces, allowing more people to fix the teeth discreetly. For those thinking of fixing the teeth with Invisalign, these frequently asked questions will provide more information about the treatment process.

Invisalign and Retainers: Commonly Asked Questions

Here is a list of some of the most commonly asked questions about Invisalign and retainers:

What is Invisalign?

Invisalign aligners are used to fix problems with the teeth to help patients achieve a desired smile. The process involves using 3D technology to devise a treatment plan that will fix the teeth using custom-made aligners that gradually move them into the desired position.

How many aligners will I need to fix my teeth?

It depends on the severity of the condition, but the average number of aligners that patients receive ranges from 12 to 22 aligners.

How long does Invisalign take to work?

Again, this depends on what the aligners are being used to treat and the severity of the condition. In most cases, treatments last anywhere from nine to 18 months.

How often do I have to see my dentist when using Invisalign?

Since patients get the total amount of aligners needed to fix the teeth at once, they do not have to go to the dentist for a checkup as often as a person with traditional braces. However, patients are advised to see the dentist at least once a month to monitor the progress of the teeth.

How long do I have to wear the Invisalign aligners for?

Dentists usually tell the patients how long to wear each aligner for, but each aligner is usually worn for one to two weeks before it is discarded.

Can I eat while wearing Invisalign?

Patients are advised to take out the Invisalign aligner before eating to avoid damaging the aligner or getting food stuck in it. After the meal, patients should brush the teeth and put the aligner back in their mouths.

Does wearing Invisalign aligners hurt?

Wearing the aligners for the first time will be a little uncomfortable for the first few days. After that, the discomfort goes away and the patient should only feel some pressure when placing them on, which indicates that the aligner is doing its job.

Will I have to wear a retainer after treatment is complete?

Invisalign patients will have to wear a retainer after treatment to prevent the teeth from moving back to the previous position. Retainers should be worn for 22 hours a day for the first three to six months after treatment is complete. After that, patients only have to wear the retainer at bedtime. Dentists tell patients to wear the retainer at least three nights a week for the rest of their lives to prevent the teeth from shifting.


Invisalign aligners offer an alternative option when it comes to fixing problems with your teeth. Wearing a retainer after treatment is complete is also important to keeping your teeth firmly in place. If you have more questions about Invisalign aligners and how they work, schedule an appointment with your dentist to get more information before you decide on a treatment option.
