Ultra-strength teeth whitening gel for experienced whitening users

White in Minutes 44% Carbamide Peroxide Teeth Whitening Gel is our highest-strength carbamide peroxide whitening formula, designed for experienced whitening users and professionals seeking a higher-strength option for more intensive whitening.

Compatible with most whitening trays and LED whitening systems, each 10 mL syringe provides up to 10 whitening applications and is proudly manufactured in the USA.

Best uses for 44% carbamide peroxide whitening gel

White in Minutes® 44% Carbamide Peroxide Whitening Gel is our highest-strength carbamide peroxide formula and is best suited for experienced whitening users who are comfortable with stronger concentrations.

It is a good fit for:

Experienced whitening users
Moderate to heavy staining
Stains from coffee, tea, red wine, soda, tobacco, and everyday foods
Longer-term discoloration associated with aging
Shorter, higher-intensity whitening sessions
Maintenance for users already accustomed to stronger whitening gels
Professional or at-home tray whitening

If you are whitening for the first time, have sensitive teeth, or prefer a gentler approach, a lower-strength formula such as 16%, 22%, or 35% carbamide peroxide may be a better starting point.

How carbamide peroxide whitening gel works

Carbamide peroxide gradually breaks down and releases hydrogen peroxide during the whitening session. This slower release allows the whitening action to continue over time, which makes carbamide peroxide especially well suited for tray-based whitening.

As the gel works, it helps break down discoloration within the tooth surface rather than physically scrubbing stains away. Carbamide peroxide is available in multiple strengths, allowing users to choose a concentration based on whitening experience, sensitivity, and treatment goals.

44% carbamide peroxide is the highest-strength option in the White in Minutes® carbamide peroxide range and is best reserved for experienced whitening users who are comfortable with stronger formulas.

Expert Tips

Start with a shorter, 15 minute wear time and increase gradually as tolerated, up to 60 minutes.

—

Place only a small bead of gel in each tooth compartment to reduce overflow onto the gums.

—

I gel reaches the gum line, wipe away promptly before continuing your whitening session.

—

Clean your whitening trays thoroughly after every use to help extend their lifespan.

—

Protect your results by limiting coffee, tea, wine, and tobacco during your whitening routine, and keep unused gel in a cool, dark place away from heat and direct sunlight.

FAQ's

Is 44% carbamide peroxide too strong for beginners?

Because 44% carbamide peroxide is our highest-strength whitening gel, we generally recommend it for experienced whitening users rather than first-time users. If you're new to teeth whitening or have a history of tooth sensitivity, a lower concentration such as 16%, 22%, or 35% carbamide peroxide may provide a more comfortable whitening experience.

How long should I leave 44% carbamide peroxide whitening gel on my teeth?

Treatment times typically range from 20 to 60 minutes, depending on your whitening goals, previous whitening experience, and tooth sensitivity. Always follow the directions provided with your whitening system, and discontinue use if you experience excessive discomfort or irritation.

Can I use 44% carbamide peroxide with an LED whitening light?

Yes. This whitening gel is compatible with most LED teeth whitening systems, although an LED light is not required for the gel to work. Carbamide peroxide gradually releases whitening oxygen throughout the treatment, making it effective with or without an LED whitening light.

How much whitening gel should I place in my tray?

Only a small bead of whitening gel is needed in each tooth compartment of your whitening tray. Using more gel will not whiten your teeth faster and may increase the amount of gel that comes into contact with your gums.

What types of stains does 44% carbamide peroxide help remove?

This formula is designed to help reduce many common types of extrinsic tooth stains, including discoloration caused by coffee, tea, red wine, tobacco, soda, and everyday aging. Results vary from person to person depending on the type and severity of staining.

How many whitening treatments are included in one syringe?

Each 10 mL syringe provides approximately 6 to 8 whitening applications, although the exact number will vary based on the size of your whitening trays and the amount of gel used during each treatment.

What should I do if my teeth become sensitive after whitening?

Temporary tooth sensitivity can occur after any teeth whitening treatment, particularly when using higher-strength whitening gels. If sensitivity develops, pause whitening until your teeth feel comfortable again. Many customers also choose to use a desensitizing gel or remineralizing gel between whitening sessions to help improve comfort before continuing treatment.

44% carbamide

So good. Definitely a gel for multiple sessions. Every one’s results are different. I recommend for teeth whitening technician starters.

Some Good Stuff

I do teeth whitening and another young lady that has a teeth whitening business has been using this product and she turn me on to it, so I thought I would try it because she get good results. This works very well better then what I've been buying from Amazon. I will be purchasing again to use on my clients. Please keep it coming.

Pleasantly Surprised

I am a long time teeth whitener at home with my own trays. I’ve bought many products online that were just not that good. I bought whitener from the dentist office that is really good and this stuff compares to professional whitener. You’ve gotta be careful not to use too much, a little goes a long way. Happy customer

So happy you are getting great results :) And thanks for the tip for other users!

44% whitening gel

The gel worked better than I thought.

Strong and easy to use

Great company great product.

New smile

This product has worked great for me ! I strongly recommend this product .

Great Product

Love this product, I would buy it again!

best stuff

my gf told me about this company. my teeth are much better than they have ever been. i wont go back to crest strips bc those suck.

Great for Sensitivity!

I just received my order of the 22% gel and I love it! I've used other whitening products and strips in the past, but they've always hurt my teeth and bothered my gum line. This stuff is gentle, but super effective. I'm a coffee drinker, so I love that I can pop in a tray anytime my teeth start to get dull. Loving the results, thanks!

Great results in short time

After using this whitening gel for a couple days I began seeing results! I like to drink multiple cups of coffee everyday and even with that my teeth were getting whiter. Also the tray is so comfy in my teeth and I actually look forward to whitening!

Very Strong

This stuff is powerful, maybe I should have followed the instructions on the website. 10 minutes and I'm done. Good results only reason I'm not leaving 5 stars is because it's too strong for me but probably is good for other people.

So white OMG

I bought this gel in particular because the agent on the phone said it was ok for people with no sensitivity issues. I used it in my tray 6 times for 25 min per day and it is incredible how well it worked... my teeth are really really white now. Never buying anything else- seriously!!!!!!
