How To Clean Invisalign? Step-by-Step Guide

If you regularly use Invisalign, one of your major concerns would be, ‘How to clean Invisalign?’ Maintaining hygiene is essential for any appliance used in the mouth. One may forget to clean them regularly, but that can lead to discoloration and wearing off those Invisalign. In this article, we will explain all the recommended methods to clean Invisalign. 

Why Is It Important to Clean Invisalign?

Invisalign are clear retainers that not only help close the gaps between the teeth but also help align crooked teeth, overbite, crossbite, and tiled teeth. Unlike metallic braces, Invisalign is aesthetic, pain-free, and easier to maintain. To understand how to clean Invisalign, you must first understand why it is important to clean them. 

Being on your teeth all day long, Invisalign gets dirty. Food debris and bacteria form buildups on the Invisalign. Therefore, you must make a habit of washing your aligners as well whenever you brush your teeth. 

Ideally, you should brush your teeth twice every day. So, don’t forget to clean your aligners after you brush your teeth. This is a very important practice because hygiene of both the teeth and aligners is necessary to maintain oral health. If, for some reason, you can not clean them properly, you should at least rinse invisalign. 

What Happens When You Don’t Clean Invisalign?

You would better understand the answer to how to clean Invisalign if you grasped what would happen when you do not maintain their hygiene. 

You may experience:


Halitosis is known as bad breath. When the aligners are not cleaned properly, bacteria and food particles accumulate on them. As a result of food deposition, a bad smell takes over the mouth. Many people opt for taking mints and mouth-freshening sprays, but they do not nip the evil in the bud. There would be no requirement for mouth freshers if hygiene is maintained, as the mouth would be clean and bacteria-free. 


One of the major disadvantages of not cleaning Invisalign is discoloration. The clear and transparent nature of the aligners becomes faded and attains a yellowish hue. That yellowish hue makes the teeth look yellow, which gives them an aesthetic appeal. 

Bacterial Overload

An unhygienic environment always acts as a magnet for bacteria. When Invisalign is not cleaned properly, then bacterial colonies increase in number, increasing your probability of falling sick. These bacteria can potentially cause various periodontal and gum diseases as well.

After understanding why it is important to clean them and what consequences you can face by not maintaining hygiene, let’s develop a thorough understanding of the best methods to clean clear aligners. 

How To Clean Invisalign With Vinegar?

Yes, vinegar. Vinegar is 5% acetic acid and is found in almost every home. Vinegar is preferred as a cleanser due to its anti-microbial properties, as proven by the research. If you use Invisalign and have vinegar at home, you have the answer to ‘How to clean Invisalign?’ in your palm.

  • Use a soft, manual toothbrush to cleanse the aligners. 
  • Once it’s done, remove the aligners from that solution and soak them in plain water for 5-10 minutes. This is necessary as it will fade and minimize the strong scent of vinegar. 

How To Clean Invisalign With Hydrogen Peroxide?

Hydrogen peroxide is yet another best agent to cleanse aligners with. Hydrogen peroxide is ideal for removing the stains or discoloration of Invisalign. It is pretty simple. You need to mix equal amounts of lukewarm water and hydrogen peroxide. Soak your aligners in that solution for 20 minutes, remove and rinse, and then use them again. Stains are often difficult to remove, so you may need to try repeatedly.

  • After 1 hour, remove them and use them. 

This is an effective but time-consuming process. You can always alternate your cleaning methods during the week. 

How To Clean Invisalign With Toothpaste?

The simplest of all is toothpaste. You regularly brush your teeth twice a day with a toothbrush and toothpaste. Similarly, you can use a soft, manual toothbrush with toothpaste to clean the aligners. This is also an effective and quick practice.
