The path to a pearly-white smile might sometimes require a lot of effort. When using Invisalign clear aligners, additional care must be taken to ensure that they stay transparent and stain-free; otherwise, your teeth and the Invisalign aligners may acquire a yellow tint.

You may be in the midst of your Invisalign treatment, and now you wonder: Can you whiten your teeth with Invisalign aligners?

In this article, we’ll be covering the following:

  • Can you whiten your teeth with Invisalign?
  • How to whiten your teeth with Invisalign
  • Best Invisalign whitening gels and Invisalign whitening kits

We will answer the questions you may have about whitening your teeth during and after Invisalign treatment, and about using your Invisalign aligners or retainers for teeth whitening.

Can you whiten your teeth during your realignment with Invisalign?

We start out by addressing some cautions to be aware of.

While teeth may be whitened while using Invisalign aligners, most orthodontists will probably advise you to start the procedure six months after the realignment is finished. When teeth are realigned, they are more sensitive, which might complicate any whitening procedures you decide to have.

In addition, when your teeth move into their ultimate locations, discoloration may still appear in spots that were not exposed to whitening agents. This will give an uneven look and could be difficult to fix right away.

Whitening treatments and Invisalign aligners

Milder types of teeth whitening might work best if you wanted to undergo treatment while using aligners. These include toothpaste and certain mouthwash types that have been specially prepared with whitening agents.

Using whitening gels is a stronger choice. Dentists may recommend them, and you can use them at their clinic or at home on your own.

Because whitening gels are more potent than the majority of whitening toothpaste and mouthwashes, they come with user guidelines. It is recommended to see your dentist before utilizing whitening gel if you are interested in doing so.

Can you put whitening gel into your Invisalign aligners?

You might be wondering if you can put the whitening gel in the Invisalign trays. When looking for an answer on if it’s advisable to put the whitening gel in your retainer or Invisalign aligner, you’ll find mixed opinions.

Although they seem similar, Invisalign aligners and teeth whitening trays are not the same. The Invisalign aligners are made specifically to match the form and size of your teeth and gums; therefore, they cannot be changed into a regular tooth-whitening tray.

Applying whitening gel within the aligner might be unsafe since the chemical will be squeezed out and could irritate your gums or mouth/stomach if you swallow it.

However, according to Dr. Courtney Barry, it’s possible to use whitening gel inside your Invisalign aligners. Watch the video to understand their recommended process of teeth whitening with Invisalign aligners:

If you watched the video, you’ll notice that the workaround they recommend is to clean the excess bleaching material which is expelled from the Invisalign aligners with a cotton swab or paper towel.

Whitening your teeth with Invisalign

Teeth whitening is not the original goal of Invisalign braces; however, you’ll actually not find a tray that fits your teeth better than these. The key to attaining beautiful, even teeth whitening is to keep the bleaching chemical as near as you can get to all of the tooth surfaces.

The exact contouring of the Invisalign trays to your individual bite ensures that the whitening gel contacts your teeth evenly and closely. Even though there’s little space provided between the aligner and your teeth it can work very well, and many dental professionals, including some aligner manufacturers, recommend using them to whiten teeth.

Here you’ll find a video by a dental professional from Diamond Braces, also encouraging you to whiten your teeth with Invisalign aligners.

How to whiten your teeth with Invisalign (in easy steps)

  • Purchase an at-home teeth whitening kit that includes a syringe with bleaching gel — or visit the dentist.
  • Clean your Invisalign aligners.
  • Have some Q-tips and toothpicks ready.
  • Place the bleaching gel at the front surface of your teeth as close to the bottom of the aligner tray as possible.
  • If you need to readjust the positioning of the gel in the tray, you can do this with a toothpick.
  • Place the Invisalign aligners over your teeth, just as you normally would.
  • Now you should check if you have any excess bleaching material expelled out of the aligners. You can remove it using a cotton swab or paper towel.
  • Use the whitening gel for the recommended time.

Yes, you can whiten your teeth with the Invisalign aligners you’re using to straighten your teeth. This can be done with whitening gel inserted into your aligners, or by using separate whitening kits.

However, make sure to follow the guidelines and consult the Invisalign dentist who oversees your treatment before doing so. It could be that it's best to wait to whiten until you finish treatment, because if your teeth are very crowded or overlapped, then you may have some spots that are noticeably darker once your teeth are straightened.
