Invisalign Cleaning Crystals are the official cleaning powder made by Align Technology specifically for Invisalign aligners and Vivera retainers. You dissolve one packet in lukewarm water, soak your trays for 15 minutes, then rinse. The crystals remove plaque, calcium buildup, and odor without scratching the plastic. They come in a box of 50 packets and are the only cleaning product Invisalign officially endorses for daily aligner care. Whether they are necessary depends on your routine, but most patients find that cleaning their aligners with crystals once or twice a week keeps trays clear, fresh, and odor free.

If you wear Invisalign, you have probably wondered whether the official Cleaning Crystals are worth their price tag, what they actually do, and how to use them correctly. Below we cover everything Brooklyn patients ask about Invisalign Cleaning Crystals, from how they work to whether the cheaper alternatives are good enough.
What Are Invisalign Cleaning Crystals?
Invisalign Cleaning Crystals are a proprietary cleaning powder developed by Align Technology, the same company that makes Invisalign aligners. Each box contains a series of single use packets that you dissolve in water to create a cleaning solution. The crystals are designed specifically to clean the soft thermoplastic that Invisalign trays and Vivera retainers are made from.
The product comes in small white packets. You add one packet to a glass of lukewarm water, drop your aligners in, swirl gently, and let them soak for 15 minutes. The crystals dissolve completely, dislodging plaque, calcium deposits, and food particles that brushing alone cannot remove.
How Do Invisalign Cleaning Crystals Work?
The active ingredients are sodium sulfate and sodium carbonate, an effervescent combination that gently lifts buildup off the aligner surface. The mild abrasive action of the dissolving crystals reaches into the small ridges and grooves where bacteria and plaque accumulate, without scratching the smooth thermoplastic.
Plaque on aligners is more than a cosmetic problem. Bacteria from your saliva and the food particles that get trapped between the aligner and your teeth can lead to bad breath, white film on the trays, and increased risk of cavities or gum issues during treatment. Cleaning Crystals reduce that bacterial load and keep your aligners as clear as the day you started wearing them.
How to Use Invisalign Cleaning Crystals: Step by Step
Step 1. Remove your aligners and brush them gently with a soft toothbrush and water to get rid of surface debris.
Step 2. Fill a clean glass or the dental cup that came with your Invisalign starter kit with enough lukewarm water to fully cover both aligners. Avoid hot water, which can warp the plastic.
Step 3. Empty one Cleaning Crystals packet into the water. The crystals will start to fizz and dissolve.
Step 4. Place both aligners in the glass and swirl gently to ensure they are fully submerged.
Step 5. Let them soak for 15 minutes. Do not exceed 15 minutes, as longer soaks offer no extra benefit.
Step 6. Remove your aligners, rinse them thoroughly with lukewarm water, and brush them once more before placing them back in your mouth.
Step 7. Discard the used solution. Each packet is single use and the solution loses its effectiveness once dissolved.
Most patients run this process once or twice a week. If your aligners look cloudy or you notice an odor, soak more often.
Are Invisalign Cleaning Crystals Worth It?
The honest answer is yes for most patients, especially in the first six months of treatment. The crystals are formulated specifically for the plastic in Invisalign trays, and Align Technology stands behind them as the only product officially endorsed for daily aligner care. When bought in bulk, each packet adds only a small monthly cost when used once or twice a week.
The case against them is that several over the counter alternatives also work well. Retainer Brite, denture cleaner tablets, hydrogen peroxide and water solutions, and even diluted distilled white vinegar have all been used by patients with reasonable results. The trade off is that none of those products are formally tested on Invisalign plastic, so any long term effects on tray clarity or material integrity are not guaranteed.
| Cleaning Method | Cost per use | Aligner Safe |
|---|---|---|
| Invisalign Cleaning Crystals | varies | Officially endorsed |
| Retainer Brite tablets | varies | Generally safe |
| Denture cleaner tablets | varies | Generally safe, may discolor |
| Hydrogen peroxide soak | varies | Safe diluted, can dry plastic |
| Distilled white vinegar (1:3 ratio) | varies | Safe but smells strongly |
What You Should Never Use to Clean Invisalign
Some common cleaning products will damage your aligners or stain the plastic. Avoid these even when traveling.
⚠ Do Not Use These on Invisalign
- Toothpaste contains abrasives that scratch and cloud the trays
- Mouthwash with dye stains the plastic permanently
- Bleach or chlorine degrades the thermoplastic
- Hot water warps and distorts the trays
- Dishwasher heat melts the aligner
Where to Buy Invisalign Cleaning Crystals
You can buy Cleaning Crystals directly from your orthodontist or online. Brace Central Orthodontics keeps them in stock for current Invisalign patients. Online options include Amazon, the official Invisalign store, and most major dental supply retailers. A 50 packet box typically lasts six months to a year depending on how often you use them.
If you are between appointments and need to extend a packet, do not split it across two sessions. The cleaning effectiveness depends on the full dose dissolving in water at once.
“It’s preferable to brush it. But if that’s impossible, at least you should rinse it before putting it back in your mouth.”

Daily Habits That Reduce How Often You Need Cleaning Crystals
The cleaner you keep your aligners day to day, the less often you need a deep clean. Here is what every Invisalign patient at our Brooklyn office hears at their first appointment.
- Rinse your aligners every time you take them out. Even if you only remove them for water, rinse before placing them back.
- Brush your teeth before reinserting. Food trapped between teeth and aligners is the single biggest cause of cloudy trays and aligner odor.
- Brush your aligners with a soft toothbrush and water at least twice a day. Avoid toothpaste, which scratches.
- Store aligners in their case when not in your mouth. Bacteria, dust, and dropped trays are the second biggest cause of buildup.
- Drink only water while wearing aligners. Coffee, tea, soda, and juice all stain the trays and feed bacteria.
Patients who follow these five habits often only need Cleaning Crystals once a week or less. Patients who skip them often need crystals two or three times a week to keep aligners clear.

Frequently Asked Questions
How often should I use Invisalign Cleaning Crystals?
Most patients use them once or twice a week. If your aligners look cloudy, smell off, or feel rough, soak more often. Daily use is unnecessary and is not more effective.
Can I use Cleaning Crystals on my Vivera retainers?
Yes. The same crystals work on Vivera retainers, which are made of the same thermoplastic as Invisalign aligners. Continue the same weekly soak routine after treatment ends.
Are Invisalign Cleaning Crystals the same as denture cleaner?
No. Invisalign Cleaning Crystals are formulated specifically for the thermoplastic in Invisalign trays. Denture cleaner tablets contain stronger abrasives and bleaching agents that can discolor or weaken aligner plastic over time.
What happens if I leave my aligners in the cleaning solution overnight?
Nothing dramatic, but it is unnecessary. The 15 minute soak time is calibrated to the chemistry of the crystals. After 15 minutes, the solution loses its cleaning power. Long soaks waste a packet.
Can I use these on a different brand of clear aligners?
The crystals are designed for Invisalign aligners and Vivera retainers. They are generally safe on other thermoplastic clear aligners but Align Technology only tests them on its own products. If you wear a different brand, ask your orthodontist for their cleaning recommendation.
Why do my aligners still smell bad even after I use the crystals?
Persistent odor usually means food or plaque is trapped between the aligner and your teeth, not on the aligner surface. Brush your teeth thoroughly before putting your aligners back in, and rinse the trays every time you remove them. If the odor persists, contact your orthodontist.
