Teeth whitening gel for at-home whitening

Looking for effective teeth whitening gel to use with your existing whitening trays? White in Minutes® carbamide peroxide whitening gel makes it easy to continue your at-home teeth whitening routine without purchasing an entirely new whitening kit.

Our teeth whitening gel refills are available in 16%, 22%, 35%, and 44% carbamide peroxide concentrations. Each 10 mL syringe provides up to 10 whitening applications, depending on the amount used. Choose a single syringe or purchase a multi-pack for regular whitening and maintenance.

These whitening gels are designed for compatible whitening trays, including custom-fitted and universal tray-style whitening systems. Peroxide-based whitening can help lighten discoloration associated with common staining habits, including coffee, tea, wine, and tobacco.

Choose the right teeth whitening gel strength

Choosing the right carbamide peroxide whitening gel depends on your whitening experience, tooth sensitivity, and the instructions for your whitening system. We offer four concentrations to accommodate different whitening preferences and experience levels.

16% carbamide peroxide: A lower-strength option for first-time users and customers who prefer a gentler approach to teeth whitening.

22% carbamide peroxide: A balanced concentration for customers looking for a moderate-strength whitening gel.

35% carbamide peroxide: A higher-strength formula for experienced users who follow the recommended application instructions.

44% carbamide peroxide: Our strongest carbamide peroxide whitening gel, intended only for appropriately experienced users following the product's specific safety and use instructions.

Higher peroxide concentrations can increase the risk of tooth sensitivity and gum irritation. Always follow the instructions provided with your selected whitening gel and consult your dental professional if you're uncertain which strength is appropriate for you.

What is the best teeth whitening gel for your needs?

The best teeth whitening gel depends on your whitening goals, tooth sensitivity, experience with peroxide-based whitening, and the type of whitening trays you use. Whether you're looking for a convenient whitening gel refill, the best whitening gel for sensitive teeth, or a stronger teeth whitening gel, choosing an appropriate concentration is important for effective whitening results.

If you're whitening for the first time or have sensitive teeth, 16% carbamide peroxide may be a more comfortable starting point. For customers already familiar with tray-based whitening, 22% and 35% carbamide peroxide offer additional concentration options. Our 44% carbamide peroxide gel is the strongest concentration in this collection and should be used only by appropriately experienced users following its safety directions.

When comparing the most effective teeth whitening gel options, consider more than peroxide strength alone. Proper application, tray fit, recommended contact time, tooth sensitivity, and consistent use all influence your whitening experience. A higher peroxide concentration does not automatically make a formula the best choice for every person.

Teeth whitening gel refills for your existing trays

You don't need to replace your entire whitening system every time you run out of gel. If you already have compatible whitening trays, purchasing teeth whitening gel refills is a convenient way to continue your whitening routine.

Our whitening gel is available in individual 10 mL syringes and multi-packs, giving you the flexibility to choose the quantity that fits your needs. Whether you're replenishing your favorite formula or preparing for future whitening treatments, our refill options make it easy to buy teeth whitening gel without purchasing a complete kit.

FAQs

What is the best teeth whitening gel for at-home use?

The best teeth whitening gel for at-home use is one that matches your whitening goals, sensitivity level, and whitening tray system. Carbamide peroxide is a commonly used whitening ingredient that helps remove discoloration without requiring an in-office whitening treatment. White in Minutes® offers four concentrations so you can choose a formula suited to your experience and preferences. For a more detailed comparison, read our Teeth Whitening Gel Strength Guide

What makes a teeth whitening gel most effective?

The most effective teeth whitening gel isn't necessarily the one with the highest peroxide concentration. Results depend on the active ingredient, concentration, proper application, treatment duration, and the type of discoloration being treated. Carbamide peroxide gradually releases hydrogen peroxide, which penetrates tooth structure to break down stain-causing compounds. Using an appropriate formula consistently and following its instructions generally matters more than simply choosing the strongest gel.

What is the strongest teeth whitening gel available for home use?

White in Minutes® offers carbamide peroxide whitening gels in 16%, 22%, 35%, and 44% concentrations, with 44% being our highest-strength formula. Stronger teeth whitening gels are not automatically better for everyone, and higher concentrations can increase the likelihood of tooth sensitivity and gum irritation. Our 44% formula is intended for appropriately experienced users following its specific application and safety instructions. If you're uncertain whether a high-strength gel is appropriate, consult your dentist.

Can I use teeth whitening gel refills with my existing whitening trays?

Yes! White in Minutes® teeth whitening gel refills are designed for use with compatible custom-fitted and universal whitening trays, including many tray-style whitening systems purchased elsewhere. You don't need to purchase an entirely new teeth whitening kit when you run out of gel. Simply choose your preferred concentration and refill quantity, and follow the product's application instructions. Avoid overfilling your trays, as excess gel can contact and irritate your gums.

Which teeth whitening gel is best for sensitive teeth?

For people with sensitive teeth, a lower-concentration whitening gel is generally a better starting point. Our 16% carbamide peroxide formula is a popular option for first-time whitening users and those who prefer a gentler approach. Tooth sensitivity can still occur with any peroxide-based whitening treatment, so follow the recommended wear time and avoid excessive application. If sensitivity develops, pause treatment and consult your dentist if discomfort persists.

Explore our Teeth Whitening for Sensitive Teeth collection for additional whitening options designed with sensitivity in mind.

How many teeth whitening treatments can I get from a 10 mL gel syringe?

Each White in Minutes® 10 mL carbamide peroxide whitening gel syringe can provide up to 10 whitening applications, depending on the amount of gel used per treatment and the size of your whitening trays. Only a small amount of gel is needed for each application, and using more won't necessarily improve results. Individual syringes and multi-packs are available, making it convenient to refill your whitening trays or stock up for future treatments.
