How to Clean Invisalign Trays?

It is important to remember to clean your Invisalign trays regularly, since wearing an isolated piece of plastic around your teeth will cause plaque buildup on your teeth and inside the tray. As you might know, if plaque is not cleaned off by brushing, it can develop into tartar, which can cause further issues. 


The best way to keep Invisalign clean is to brush them separately, when brushing your teeth. A normal toothbrush is sufficient, but for a deep clean, use an electric toothbrush. If the damage is done, and your aligners are stained, your best bet is cleaning tablets made specifically for Invisalign and/or retainers. In the future, try avoiding coffee, soda, tea and other staining beverages.


Never soak your Invisalign in mouthwash to clean them. If you need to disinfect the aligners and de-stain the aligners, use the provided cleaning crystals. There are cleaning tablets made specifically for retainers and clear aligners, so make sure you stock up on those. You can find Invisalign’s cleaning crystals right here.

Never use hot water to clean your aligners, as this can warp the aligners shape and therefore resulting in useless aligners. If you have warped your aligners and they no longer fit, go back to your previous tray or next tray. Do not attempt to force the aligners to fit your teeth. Make sure you consult your dentist for new trays or advice.

Never use toothpaste to clean your Invisalign. For some reason, the ingredients in toothpaste results in foggy aligners, which defeats the purpose of clear aligners. So if you want to keep your Invisalign clear and invisible, don’t use toothpaste to clean them.

In conclusion

The best way to keep your clear aligners clean and odor-free is to brush them regularly. Whenever you need to take your Invisalign out, run them under cold water and shake off any excess water. A good rule is also to make sure to take out your Invisalign when drinking a non-clear liquid such as soda, tea, coffee etc. It’s also a good idea to disinfect the trays regularly, with cleaning tablets made for retainers and clear aligners.
