How to Remove Yellow Stains From Your Invisible Aligners

Invisalign trays are a popular method for straightening teeth without wearing traditional braces. However, these trays sometimes grow yellow or stained over time as a result of improper cleaning. Luckily, there are a number of ways to get rid of these unpleasant stains. In our latest article, Movemints offers a guide on the best way to clean Invisalign stains from your trays. 

Soak Your Trays in a Solution

There Are a Number of Cleaning Solutions You Can Soak Your Trays In

The best way to clean Invisalign stains is by soaking your aligners in a solution. There are numerous solutions you can use. Some solutions are better for removing stains while others are more effective in removing dried plaque or food. Here are our top Invisalign cleaning solution recommendations. 

Invisalign Crystals and Water

One of the most effective methods for removing Invisalign stains from your trays is by placing them in a mixture containing Invisalign cleaning crystals. Simply fill a cup with enough warm water to fully immerse your aligners before adding a pack of crystals. Stir the mixture for about 20 seconds until the crystals fully dissolve. Soak the aligners for around 15 minutes. When they are finished soaking, rinse them in warm water before placing them back in your mouth or storing them in their container. 

Hydrogen Peroxide

A mixture made of 50% strength hydrogen peroxide and water is another effective solution for eliminating stains on your Invisalign trays. Adding baking soda to the mixture can also help you remove dried plaque and food from your aligners. 

The final solution should be comprised of:

  • Half water
  • Half 50% strength hydrogen peroxide
  • 2 tablespoons of baking soda

Depending on how severe your stains are, it could take several hours to completely clean off your trays. Consider soaking them overnight if there is significant staining on your aligners. 

Vinegar Solution

Vinegar is also extremely effective in cleaning trays, especially if the staining on them is minimal. Make a solution comprised of one part vinegar and three parts water. Soak your aligners in the solution for about 20 minutes before thoroughly brushing and rinsing them. Residual vinegar is never a pleasant taste. 

Methods for Preventing Your Aligners from Developing Yellow Stains

The Best Way to Clean Invisalign Trays is Through Preventative Measures

Most of the time, Invisalign stains are caused by drinking too much coffee or from a lack of cleaning. Removing Invisalign stains from your trays is not a simple task. It takes time and patience to completely clean your trays. That’s why preventative measures, such as a regular cleaning and soaking schedule, are important to follow. 

1. Rinse Your Aligners Whenever You Remove Them

While it can be easy to forget to rinse your aligners whenever you remove them, doing so is imperative for preventing staining. As you continue to integrate this habit into your normal routine, it will become second nature to rinse your aligners whenever you take them out. Remember to soak your trays in cool or lukewarm water, as hot water can warp them. 

2. Brush Your Trays with an Anti-Bacterial Soft Soap

Whenever you brush your teeth, you should also brush your trays using an anti-bacterial soft soap. As you brush your tray, remember to use gentle, circular motions. Brushing too hard can wear down the surface of your trays. 

3. Remove Your Trays Whenever You Drink or Eat

Fruit drinks, tea, wine, and coffee are known for staining your teeth and aligners. Make sure you remove your aligners whenever you drink anything other than water. You should also rinse your mouth with water before placing your trays back in. This will ensure that any leftover drink or food is washed away. 

4. Bonus Tip: Chew on a Mint to Keep Your Mouth Fresh and Hydrated

Many patients suffer from Invisalign dry mouth, a common but irritating condition. Some patients try to keep their mouths hydrated and fresh by sucking on sugar-free mints. However, these mints typically contain artificial sweeteners that are harmful to your teeth. 

That’s why Invisalign users are turning to Movemints. These mints, which are designed specifically for Invisalign wearers, are made with xylitol. Xylitol tastes just like sugar, but can actually improve your dental health rather than worsening it or putting you at risk of developing oral issues. Because Movemints are designed with patented grooves, they can easily fit between both your upper and lower trays.
