Invisalign is a modern, alternative, and clear teeth alignment treatment. It helps you treat mild to moderate, and some severe malocclusions by wearing a set of clear aligner trays for 20-22 hours each day. These trays help shift your teeth into the proper positions gradually, so it is essential to wear these aligner trays for the recommended time. Hence, cleaning them regularly is also equally important. Invisalign recommends using their patented cleaning crystals to clean the aligner trays. But how to use Invisalign cleaning crystals? And more importantly, what are they, and why are they the best, most efficient cleaning tool for your Invisalign aligners? Let’s read more to find out.

What Are Invisalign Cleaning Crystals

Invisalign cleaning crystals are a patented cleaning tool created by Invisalign for regular cleanliness and maintenance of the aligner trays. They can help remove harmful germs and bacteria that may have accumulated in your aligners throughout the day. They can also aid in removing any plaque buildup that may have developed on the aligners. Most importantly, these crystals, when dissolved in water and used as a cleaning solution, help prevent staining, discoloration, and development of any foul smells or odors in your clear aligners. These special Invisalign brand cleaning crystals are non-toxic as they contain compounds like sodium carbonate, sodium sulfate, sodium dichloro isocyanurate, sodium lauryl sulfate, and sodium tripolyphosphate, which make for safe and effective cleaning for your aligners.

Why Should You Use Invisalign Cleaning Crystals

Apart from the obvious, there are several reasons why you should make use of the Invisalign crystal cleaning solution. Some of those reasons are:

  • The crystals help you keep your aligners sanitized when using them regularly. It’s a device that is placed inside your mouth, and it being safe and sanitized is most important.
  • The Invisalign cleaning system crystals help to keep your aligners transparent and invisible as they prevent the development of stains and discoloration.
  • These patented crystals also kill any harmful bacteria that may have gotten into the crevices of the aligners due to food or beverage residue and prevent you from contracting gingivitis, gum disease, cavities, and tooth decay.
  • Harmful bacteria develop due to food residue, and can even lead to plaque buildups, and regular cleaning with the crystals can clear those buildups from your clear aligners.
  • These crystals help prevent any external damage to your teeth, and keep your smile white and fresh!

General Tips to Keep Aligners Clean 

  • Cleaning aligners twice a day: Just like your teeth, your Invisalign aligner also needs to be cleaned twice a day, once in the morning and once at night. This will help prevent the buildup of harmful germs and bacteria, and keep the aligners invisible and bright.
  • Remove aligners while eating or drinking: If you wear your aligners while eating, you risk damaging the aligners due to staining, plaque buildup due to food residue, tiny scratches that develop due to chewing, and buildup of tartar which can lead to gingivitis. Hence, it is recommended to remove the clear aligners while eating to ensure the least amount of contamination and damage.
  • Storing in a case: When you aren’t wearing your aligners, you can store them in a case to prevent any physical damage or bacterial contamination.
  • Flossing regularly: Adding flossing to your dental regimen can help prevent any unnecessary food residue between teeth, and help keep your aligners clean, transparent, and free of buildup.
  • Soaking and rinsing: Try rinsing and soaking your aligners at regular intervals throughout the day, even if it’s just with warm water, plays a major role in keeping them clean and free of bacterial contamination and foul odor.
