The Dr. Collins Teeth Whitening Gel Refill Pack is meant to be used with whitening trays - either from your dentist or from our site. Strengths available are 10%, 16%, and 22% Carbamide Peroxide. The Dr. Collins whitening gel range was created by Dr. Collin Suzman, a practicing dentist in Orange Country, CA. Like many dentists, he recommended oral care products that were easily accessible from other companies, but wanted something better for his patients.

The Dr. Collins Teeth Whitening System is currently used by hundreds of dentists across the USA and here in the UK to supply to patients, so if you are looking for the same dentist-whitening results, but at a more affordable price, you need look no further!

The Dr. Collins range has been available for over 4 years, and has proven extremely popular due to the exceptionally high quality gel it contains - as shown by the ratings from an independent review site, shown on the right.

Bleaching Gel Refill Contents

• 3 x 5ml 10% Carbamide Peroxide bleaching gel syringes
(enough for over 30 full mouth treatments)

The Bleaching Gels are manufactured and packaged in the US. In addition, the bleaching gel is water-based which helps to prevent some of the sensitivity normally associated with whitening.

Dr. Collins Bleaching System is extremely easy to use, and each kit comes with full, detailed, and clear instructions.

Using boil-and-bite bleaching trays, a teardrop amount of teeth whitening gel is applied to the inner front surface of the tray.

Depending on whether or not you have whitened before and the concentration of the bleach, the wearing time of the tray can be anywhere from 30 minutes to 4 hours a day for up to a week.

Dr. Collins whitening gel is carbamide peroxide-based, the same as used by your dentist. Carbamide peroxide has been proven to be extremely safe and highly effective.

As you consume staining foods and drinks, smoke, or just get older, your teeth absorb dark, staining particles, which over time give a dull, yellow, or even grey appearance.

Carbamide peroxide gel works by penetrating the tiny pores of your tooth enamel and turns those stains white by oxidizing them. The gel does not interfere with the tooth enamel structure in any way.

In a recent study by the University of Rochester, USA, teeth whitening has been shown to be safer than orange juice! Concentrations of hydrogen peroxide used in professional and over the counter teeth whitening processes don't cause significant changes to tooth enamel, according to the US researchers. Conversely the researchers found that an everyday practice such as drinking acidic fruit juices can have significant negative effects on the hardness and the roughness of tooth enamel.

The scientists, led by Yan Fang Ren at the Eastman Institute for Oral Health at the University of Rochester , investigated the effects of hydrogen peroxide on tooth enamel. According to the team, when compared to orange juice the hydrogen peroxide did not lead to any significant changes in the hardness of surface enamel.

Love this product, I have pretty sensitive so I purchased the 10% and I felt next to none discomfort. On a scale of 1-10 (10 being the whitest and 1 being yellow) my teeth were at about a 4 when I started. I used it every other day for a week and after the 3rd day my teeth were easily at a 9, and I only used 1 syringe. I kept the other syringes in the fridge to help pro long the life of the whitening gel and i touch up about once a month. I had know idea how much of a difference having white teeth makes you feel and look, and its so simple. Just thought I would share my opinion with everyone. Hope it helps.

I bought the Dr. Collins all white bleaching system online. I absolutely love the product. It's by far the best value of any bleaching system on the market. I recently quit smoking and had some fairly bad staining from years of the horrible habit. After just a few uses of the Dr. Collins gel I noticed the tobacco stains fading away. I was sooooo happy to find this great valued product and it works just as advertised. I've already highly recommended this product to a number of people and will continue to do so!

Dr. Collins All White Bleaching System gets my teeth whiter than any other product I've used. The consistency is super sticky so the gel adheres to my teeth better than others. And I have never experienced any sensitivity, which is great! You would think that a whitening gel this safe and effective would cost a fortune, but Dr. Collins is actually very affordable. I highly recommend this product!
