Difference between hydrogen peroxide and carbamide peroxide

Difference between hydrogen peroxide and carbamide peroxide

Carbamide peroxide (CP) is a stabilized Hydrogen peroxide (HP) formula.

CP is similar to HP but in a more stable formula, so it does not need to be refrigerated. CP also breaks down at a slower rate than HP. 

6% HP = 22% CP
12% HP = 35% CP
16% HP = 44% CP

 

Is carbamide peroxide (CP) better than hydrogen peroxide (HP) for teeth whitening?

No. Both hydrogen peroxide (HP) formulas and carbamide peroxide (CP) formulas provide the exact same whitening results.

 

Why is Carbamide Preferred as a tooth whitening formula?

Carbamide Peroxide breaks down at a slower rate thereby having more time to access and break apart stubborn stains from coffee, smoking, tea and red wine etc that has penetrated the tooth enamel and needs to be soaked out.

Carbamide can be stored at room temperature, Hydrogen peroxide should be refrigerated.

A journal published by ADS (American Dental Association) showed that while carbamide peroxide shows slightly faster results at first, products containing both ingredients produce precisely the same results. Mar 5, 2018

What is the highest level of peroxide for teeth whitening?

6% HP = 22% CP
12% HP = 35% CP
16% HP = 44% CP

 

Does carbamide peroxide really whiten teeth?

Carbamide peroxide gradually enters tooth enamel, transforming into hydrogen peroxide. It then oxidizes pigmented molecules within the tooth structure, breaking down dark-colored compounds and lightening the natural tooth shade.

Our most popular strengths are 22% and 35%.People needing rapid results and want to wear their trays for a short time use higher strength (35% or 44%). 

Carbamide Peroxide (CP) vs Hydrogen Peroxide (HP): 

Hydrogen peroxide is used by dentists in their offices and should be used under the supervised provision. More and more dentists are switching to Carbamide Peroxide due to the comfort and safety of their patients' gums. HP is mighty and, if misused, can aggravate gums. (temporary)
Expertwhite CP Gel is a stabilized formula of HP. It is formulated to release over a slower period while worn in the teeth whitening trays, eliminating any risk of gum tissue aggravation while providing optimum whitening results.

10% Hydrogen Peroxide = 35% Carbamide Peroxide
15% Hydrogen Peroxide = 44% Carbamide Peroxide

LED / Lamp Whitening:

We recommend 44% CP. Three whitening treatments of up to 20-minute each.

Near-Neutral PH:

Expertwhite gels are near-neutral PH, providing the most comfortable and effective whitening experience with no sensitivity. 

Safety: 

Non-Toxic:

Teeth whitening is the safest cosmetic procedure available on the market today. It is, however, recommended that pregnant or lactating women refrain from use. If the gel comes into contact with eyes or skin, flush immediately with warm water. Suppose ingested in large quantities, contact physician. Continue routine dental visits. If you swallow the gel during your routine whitening, this is harmless in these quantities. Wipe excess gels off gums before and during treatment.

Abstract

Background: Vital tooth bleaching for aesthetic reasons has gained popularity during the last few years. However, few studies have investigated the efficacy of daytime bleaching products. This double-blind in vivo study aimed to evaluate the effectiveness of 20 percent carbamide peroxide, or CP, and 7.5 percent hydrogen peroxide, or HP, during daytime use. The degree of color change, color relapse, and tooth or gingival sensitivity were evaluated.

Methods: Twenty-four patients participated in this study. The bleaching gels were randomly applied to the right and left maxillary anterior teeth. Patients were shown how to place the two bleaching agents in a custom tray for one hour, twice a day for two weeks. Patients returned in one, two, three, six, and 12 weeks for color evaluation with colorimeter and shade guides and to take color slide photographs. The authors evaluated sensitivity by asking the patients to record daily for 21 days any tooth or gingival sensitivity they experienced.

Results: The 20 percent CP resulted in significantly more lightness than the 7.5 percent HP during the first 14 days of the study. However, at the end of the study, there was no significant difference between products concerning tooth lightness. In addition, the authors found no statistically significant difference between products concerning gingival or tooth sensitivity.

Conclusions: CP and HP are effective at-home bleaching agents when preferred during daytime bleaching.

Clinical implications: Dentists using daytime bleaching can select either CP or HP.
