Why This Gel Works Better

Most over-the-counter whitening gels are thin and watery, meaning they run off your teeth during treatment and deliver uneven results. This high viscosity formula is specifically designed to cling to tooth surfaces, ensuring the gel stays exactly where it needs to be for consistent, uniform whitening throughout every treatment.

What It Removes

This professional-grade formula quickly and safely eliminates stubborn stains caused by:

Coffee and tea
Tobacco and smoking
Red wine
Foods and general dietary staining
Age-related yellowing and discolouration

Most users see noticeable whitening results after their very first treatment.

What Is Carbamide Peroxide?

Carbamide Peroxide is the primary bleaching agent used in professional dental whitening. It is a dental industry adaptation of Hydrogen Peroxide, developed specifically for safe and effective tooth whitening. This formula is the same professional standard used in dental clinics throughout the USA and internationally.

What's Included

6 x 3ml whitening gel syringes (44% Carbamide Peroxide)
Full step-by-step instructions

Whitening gel is USA made. Syringe dispensers are manufactured by Becton Dickinson (NYSE: BDX), a US-based medical equipment company.

How To Use

Apply a very thin strip of gel to your dental tray only. Do not overfill. The high viscosity gel expands when activated, providing full tooth surface coverage with a minimal amount. Excess gel on the gums can cause temporary irritation, so less is more. Complete instructions are included with every kit.
