Targeted Care for Sensitive Teeth

Give sensitive teeth a little extra support with the White in Minutes® Tooth Sensitivity Relief Kit. Designed for at-home use, this complete kit combines professional-style desensitizing gel with a reusable mouth tray so the formula can stay in close contact with the teeth where it is needed most.

Whether you deal with occasional tooth sensitivity, know your teeth are prone to sensitivity during whitening, or want added comfort after a whitening treatment, this kit gives you a simple way to incorporate desensitizing care into your routine.

More Than Just a Whitening Aftercare Product

Tooth sensitivity can happen for many reasons, which is why this kit is not limited to post-whitening use. The desensitizing gel can be used as part of a general sensitivity-care routine, before whitening for sensitivity-prone teeth, or after whitening when temporary sensitivity occurs.

The formula contains potassium nitrate, calcium hydroxyapatite, and calcium pyrophosphate to help support tooth comfort and enamel care without bleaching or whitening the teeth.

A Complete At-Home Sensitivity Kit

Unlike a gel-only product, this kit includes the application essentials needed to get started. The reusable dual-arch tray helps hold the desensitizing gel against the teeth during treatment, while the included storage case keeps the tray protected between uses.

Each kit includes:

  • Two 3 mL mint-flavored desensitizing gel syringes
  • One reusable White in Minutes® dual-arch mouth tray
  • One protective tray storage case

Designed for Flexible Sensitivity Care

Use the Tooth Sensitivity Relief Kit whenever added sensitivity support fits into your routine. It can be used independently or alongside a teeth whitening regimen, making it a practical option for customers who want targeted care without changing their whitening products.

Expert Tips

Apply a thin layer.
A small, even bead of gel inside the tray is all that's needed. Using more gel won't improve comfort and may cause excess gel to reach the gums.

Target the sensitive teeth.
If only certain teeth are sensitive, apply gel only to those areas instead of filling the entire tray.

Use after whitening sessions.
Desensitizing gel can be applied immediately after whitening or whenever temporary sensitivity develops.

Wear for up to 30 minutes.
Mild sensitivity may improve after just a few minutes, while more noticeable sensitivity may benefit from a full 30-minute treatment.

Keep a syringe on hand.
Many experienced whitening users keep desensitizing gel available so they can address temporary sensitivity when it occurs rather than waiting for discomfort to increase.

FAQs

How does desensitizing gel work?

Desensitizing gel contains ingredients such as potassium nitrate, calcium hydroxyapatite, and calcium pyrophosphate that help calm sensitive teeth and support enamel. The gel is placed inside the included tray so it remains in contact with your teeth for several minutes during each treatment.

Can I use desensitizing gel before whitening my teeth?

Yes. Some people with naturally sensitive teeth choose to use desensitizing gel before beginning a whitening treatment to help improve comfort. It can also be used after whitening or between whitening sessions as needed.

How long should I leave the desensitizing gel on my teeth?

Apply a thin bead of gel to the mouth tray and wear it for 5 to 30 minutes. After treatment, remove the tray and rinse both your mouth and the tray thoroughly with water. An LED whitening light is not required.

How many treatments are included?

Each 3 mL syringe typically provides about 3 treatments, depending on how much gel is used per application. With two syringes included in the kit, most customers can expect approximately 6 treatments total.

The formula contains potassium nitrate, calcium hydroxyapatite, and calcium pyrophosphate. These ingredients are commonly used in sensitivity and enamel-support formulations.
