Frequently Asked Questions

Our Products

Teeth Whitening Kit

How do I use this product?

Simply squeeze the whitening gel onto the mouthpiece, plug the device into your phone’s charging port, and slide the tray into your mouth. You can use the Pearlii App for added support (free), as well as to monitor your 12-minute whitening sessions. Your whitening treatment is completed after 6 consecutive days.

How long should I wait between whitening treatments?

Your whitening treatment will take just 6 days, and depending on lifestyle and dietary factors will last up to 3 months. You can order whitening gel refills whenever you like from the Pearlii website or app. For best results, we recommend using the Pearlii App to support your whitening journey and determine the perfect plan for you.

How often should I replace my whitening tray?

We recommend that you change your tray every 12 months from first use for hygienic purposes.

Why doesn't my kit light up when I plug it into my Android phone ?

Our kits contain multiple plug styles, to connect any smartphone on the market. When plugging your kit in, we suggest turning on the On The Go (OTG) settings in your phone menu, this should solve the kit not lighting up problem. If you are still having this problem, please contact us at

Can this product be used with veneers, caps, implants, bridges or bonded teeth?

Pearlii's Home Teeth Whitening Kits are made strictly in line with ADA safety standards, but our products are made only for natural teeth. They do not work on veneers, caps, implants, bridges or bonded teeth because the materials used to make these do not react to the whitening formula.

How do I safely store my whitening kit?

Give your whitening tray a good rinse after use and pack it away clean and dry. Your gel refills need cool storage, so if it's a scorching summer it's best to let them chill in the fridge.

Is Pearlii's Home Teeth Whitening Kit breastfeeding friendly?

While we are confident that our products will be fine - you spit out the whitening gel after each use, so very little, if any, is swallowed - we generally err on the side of caution with respect to pregnancy and breastfeeding.

Our recommendation would be to wait until you're post-breastfeeding just to be extra, extra safe.

Gel Refills

Is the gel gluten free?

Each of the ingredients within the gel are gluten free.

What does the gel taste like?

The whitening gel tastes like toothpaste; most people find it refreshing and minty! The gel starts bubbling after a few minutes so don't be alarmed, it just means it's working!

What ingredients are in the gel?

Hydrogen Peroxide (6%), Propylene Glycol, Glycerol, Deionized Water, Carbomer, Carboxymethylcellulose Sodium, Polyvinylpyrrolidone, Menthol, Triethanolamine.

All Pearlii Whitening Gel ingredients are vegan and cruelty-free.

How long will the gel refills last for me?

Your whitening treatment will take just 6 days, and depending on lifestyle and dietary factors will last up to 3 months.

Pearlii App


How long do I have to wait for my check-up results?

Pearlii results are instant.

After taking 5 dental photos in front of a mirror (e.g. in the bathroom) with your smartphone camera. Our cutting-edge machine learning algorithm will scan your dental photos for common dental problems and generate your result in just seconds.

How does it work?

  1. We encourage you to brush your teeth before starting.
  2. You will be asked to take 5 photos of your teeth (from different angles) using your smartphone’s main camera. We need the flash for clear pictures so you won’t be able to use your selfie camera.
  3. Don’t worry, we have easy-to-follow instructions (and a quick demo) to help you get the perfect shot of your pearlii whites.
  4. Our machine learning algorithm will scan your dental photos and generate a result along with advice tailored to your results.

Do I need any special equipment for check-up?

No. All you need is a mirror and your smartphone.
We encourage you to brush your teeth before the check-up.

How much does a Pearlii dental check-up cost?

Zip. Zero. Zilch.

Pearlii dental check-up is free!

I am using the Pearlii app, does that mean I don't have to go to the dentist anymore?

Pearlii does not replace a dentist. Dentists will always be the gold standard. If you have dental pain or discomfort, we urge you to visit a dental practice as soon as possible.
Having said that, we understand that a busy schedule, budget constraints and poor geographical access are some of the things that keep people from going to the dentist. We made Pearlii to help people during the times they can't get to the dentist.

Note: Pearlii is NOT a diagnostic tool, it is a screening and educational tool.

How does this improve my oral health?

With regular preventative care, potential issues can be identified earlier and treated before they become a serious problem. Pearlii's AI check-ups makes it quicker, easier and cheaper to detect potential issues and act early against oral health risks.

Our Technology

So... What is Artificial Intelligence?

Put simply, machine learning is a type of AI, where we feed the machine data to help it improve itself. Machine learning trains an algorithm so it can learn how to make decisions.

What research are you doing to improve and test your technology?

Pearlii has multiple dentists onboard to test and improve our technology. We are also in the process of conducting academic research (e.g. validity and reliability studies) to better understand our technology's capabilities and limitations against a standard, in-person clinical assessment with and without x-ray. We plan to adopt an open-source approach to our research and to publish findings in peer-reviewed academic journals


Is my data safe and secure?

Pearlii takes all of the necessary precautions to ensure your data is safe and securely stored in the cloud. We follow strict internal policies to ensure operational security, while our systems are designed to minimise all processing of your personal data. Furthermore, all data that we use for machine learning training purposes is anonymised and transferred through encrypted networks.

What happens to my photos?

Photos are encrypted and stored in the cloud. For extra security all images are deidentified and stored separately.

Our Impact

What does Pearlii stand for?

Our mission is to improve oral health around the globe. Oral diseases are largely preventable and can be easily treated in their early stages. However, billions of people have no or very limited access to dental care or basic health education.

We've developed world-first AI technology that provides free, fast dental check-ups, along with free oral health education tailored to individual results.

Furthermore, Pearlii is giving back 50% of its profits to provide free dental surgery for people who can't afford or access a dentist.
