Technical Details

Immediate Relief

UltraEZ gel provides fast relief and starts working immediately. And its unique sustained-release formula provides benefits even after the application is over.1

The Perfect Complement for Opalescence™ Boost™ In-Office Whitening

Sensitivity is a challenge with all tooth whitening procedures. Naturally, in-office whitening can cause more sensitivity because of the higher concentration of peroxide used during treatment. Having an UltraEZ desensitizing gel treatment handy can be a great way to show your patients you care about not only their oral health and appearance, but their comfort level as well.

Potassium Nitrate and Fluoride

UltraEZ desensitizing gel contains an optimum amount of potassium nitrate. Findings have confirmed that the potassium nitrate helps to minimize sensitivity.1

Ideal for Multiple Procedures

For some patients, tooth sensitivity can be a side effect of tooth whitening, toothbrush abrasion, thermal and chemical changes, and root exposure. Sensitivity may even discourage those patients from further treatments. Providing a treatment that immediately helps eliminate tooth sensitivity will ensure a better experience for your patients.

Delivery Options

UltraEZ desensitizing gel is available in two convenient delivery options. For patients with custom trays, offer UltraEZ gel in syringes. The application is the same as Opalescence whitening in syringes, so your patients will already be familiar with it. For patients who don’t have custom trays, UltraEZ gel also comes in prefilled, disposable trays. These are the same UltraFit trays found in our Opalescence Go whitening! They are extremely comfortable, adapting to the shape of the patients' anatomy, while also ensuring the gel stays in place to provide optimal results.

Great for Use Before or After Whitening

UltraEZ desensitizing gel is great for treating sensitivity after a whitening procedure, but it can also be great for use before a whitening treatment begins. For patients with a history of sensitivity or those who test positive during a sensitivity exam using air or touch, invite them to complete one or two UltraEZ gel treatments before the whitening treatment begins. The extra dose of potassium nitrate and fluoride can be just the thing to get them to the end of their whitening treatment as comfortably as possible.

Enhances Patient Compliance

UltraEZ desensitizing gel minimizes sensitivity, which can enhance patient satisfaction and improve compliance with whitening treatments.2 The more comfortable the whitening procedure is for the patient, the more likely they’ll be to complete it and get the results they’re looking for.

"​I never let a patient leave my office without UltraEZ because I know from experience it works! Some patients don't experience sensitivity till after they leave the office, and I want them to always have the option of UltraEZ if they need it."

Dr. Owen Mandanas – Anchorage, AK

"​We love it when new patients tell us they have tried whitening at their previous dental office, but it made their teeth too sensitive and they had to stop. UltraEZ takes care of that problem for us and makes us look like heroes. Thank you UltraEZ!!!!"

Dr. Martini & Dr. Muscaro – Tampa, FL

"​If sensitivity occurs after whitening, I am prepared with UltraEZ. It quickly eliminates my sensitivity and my patients'. We all love it."
