A Look at PAP+ as an Alternative to Hydrogen Peroxide-based ...

If you use social media, you are fully aware of the vanity that we pour into our looks. Some of us are so self-conscious that we use photo filters to smooth our skin and give our appearance an airbrushed look. Therefore, when a recent study performed by Mintel/Greenfield Online revealed that 67% of Americans had whitened their teeth, it came as no surprise.1

Look not at me to cast out shame, for I am as guilty as the next and feel that whiter teeth can help instill confidence in a person’s smile.

History of Teeth Whitening

How did we get here? While many attempted to whiten their teeth using various methods, teeth whitening did not officially hit the consumer market until the s. During the s, peroxide was used as an oral antiseptic gel to treat gingival tissue. When the gel came in contact with the enamel, it was discovered that the surface was whitened after a patient was asked to use an overnight soak of carbamide peroxide for gingival health.3

This discovery eventually led to the use of peroxide gels to achieve whiter teeth. Prior to this, teeth whitening was achieved through various methods:2-4

• Ancient Egyptians used a paste comprised of ground pumice stone, white vinegar, and ground oxen hooves in an attempt to whiten their teeth.
• Ancient Romans used urine to whiten their teeth because of the ammonia it contains.
• In the 17th century, barbers would apply nitric acid to the teeth to lighten the color.
• In the late s, chlorine was a popular method of teeth whitening.

Teeth Whitening Today

The active ingredient in most teeth-whitening agents today is peroxide, which is delivered as either hydrogen peroxide (HP) or carbamide peroxide (CP). Both agents work to oxidize the chromogens ‒ or darker shades of the tooth ‒ by relying on free radicals to produce a lighter shade.5 Carbamide peroxide is an adduct of hydrogen peroxide; in other words, it is a stable complex that breaks down in contact with water to release hydrogen peroxide.5 Therefore, almost all whitening agents contain hydrogen peroxide.

These agents can be found in multiple delivery methods, including in-office whitening, take-home custom trays, whitening strips, prefabricated trays, pens, and pastes. Unfortunately, peroxide-based whitening agents have been known to create reversible pulpitis or tooth sensitivity.7

High concentrations of hydrogen peroxide whitening agents can also lead to organic matrix damage within the tooth.7 Similarly, high doses of carbamide peroxide can lead to surface enamel damage.7 The oral mucosa is also subject to irritation or burns when in contact with peroxide-based agents. Risks increase with the concentration of the administered dose.

A newer agent, phthalimidoperoxycaproic acid (PAP), is making its debut and has also shown positive results in whitening tooth enamel. PAP is a non-peroxide-based solution that has shown to be just as effective as peroxide-based products.6 This organic peroxy acid is used as a bleaching activator in laundry detergents, and thus the idea to use it as a teeth whitener was born.

However, some studies initially reported that PAP could equally cause enamel surface damage. After this conclusion, nano-hydroxyapatite was added to the formula to prevent mineral loss, resulting in zero nanoscale roughness of the enamel; thus, PAP+ was born. During the oxidation process of whitening, no reactive oxygen species (ROS) or free radicals were formed when using PAP+, which is important as free radicals are believed to be the causative factor of sensitivity during conventional HP and CP whitening.8

The new formula of PAP+ also consists of potassium citrate to assist in desensitizing exposed dentin. Potassium citrate also serves to maintain the pH level of the oral mucosa. PAP+ is a quick-acting whitening formula that does not irritate the surrounding soft tissues. Accordingly, barriers are not required when used in an office setting.

Hydrogen Peroxide vs. PAP+

While both peroxide and PAP+ are effective in whitening teeth, some studies reveal that PAP+ is superior to HP. PAP+ has been shown to alter a range of chromogens, including polyphenols. Polyphenols are organic molecules found in food and beverages such as red wine and tea. They can be oxidized by phthalimidoperoxycaproic acid to quinones and then potentially undergo further rearrangement reactions.8

Studies also conclude that PAP+ does not alter the integrity of the enamel, while peroxide-based agents reduce the microhardness of the enamel.8 PAP+ works quickly and has been proven to enhance the enamel color by eight shades in just six 10-minute treatments.8 Considering the relative newness of this agent, ongoing studies may be necessary to validate its safety and effectiveness further.

Conclusion

The global teeth whitening market is expected to reach $10.6 billion by .1 Dental professionals should serve as a guide to this coveted cosmetic procedure. It is essential that we educate the patient on obtaining optimal oral health prior to any teeth whitening. Through education, we serve to provide oral hygiene instruction that the patients can use continually to improve their oral health. Improving one’s oral health may be used as an incentive to eventually whiten the teeth.

Dental professionals should also discuss the various methods of teeth whitening and help the patient choose the best method. Considering many methods are readily available over the counter dental professionals should intervene to guide patients to the correct choice and further monitor their dental health while whitening.

Introduction

Teeth whitening is a highly sought-after cosmetic treatment, but with so many options available, it can be difficult to know which method is the most effective and safest. PAP+ (Phthalimidoperoxycaproic acid) and hydrogen peroxideare two of the most widely used whitening agents today. While both are effective, they work in different ways and offer different levels of safety for your teeth. In this article, we’ll compare PAP+ and hydrogen peroxide based on whitening effectiveness, safety, and potential side effects, helping you make a more informed decision about which option is right for you.

How Do PAP+ and Hydrogen Peroxide Work?

Hydrogen Peroxide has long been used as a whitening agent. It works by releasing free radicals that break down stains on the tooth enamel. While effective, this process can also harm the enamel, especially when used in high concentrations or over long periods, leading to sensitivity and potential long-term damage.

In contrast, PAP+ is a newer whitening agent that works by oxidizing tooth stains without generating harmful free radicals. This makes PAP+ a gentler option for whitening, providing effective results while preserving enamel integrity.

Whitening Effectiveness: PAP+ vs. Hydrogen Peroxide

Both whitening agents are effective, but their mechanisms differ:

-Hydrogen Peroxide: Known for its ability to remove stains, hydrogen peroxide works quickly. However, its whitening power can lead to tooth sensitivity and enamel damage, especially with frequent use.1

-PAP+: Studies have shown that PAP+ delivers comparable whitening results to hydrogen peroxide, particularly for stains caused by coffee, tea, and other common staining agents. Since it doesn’t generate harmful free radicals, PAP+ is a safer option that preserves enamel while still providing noticeable whitening.2

Safety: Which Is Safer for Your Teeth?

When it comes to safety, PAP+ and hydrogen peroxide differ significantly:

-Hydrogen Peroxide: While hydrogen peroxide is widely used and effective, it can be harsh on tooth enamel. Overuse can result in enamel erosion, leading to long-term damage and increased sensitivity. It may also irritate the gums in some cases.1,3,4

-PAP+: PAP+ is gentler on tooth enamel, making it a safer option for long-term whitening. Unlike hydrogen peroxide, PAP+ doesn’t release harmful free radicals, which can damage enamel. As a result, PAP+ is often recommended for people who want to whiten their teeth without worrying about sensitivity or enamel degradation .2

Blue Light Therapy and PAP+: A Synergistic Whitening Solution

One of the most exciting trends in teeth whitening is the use of blue light therapy in conjunction with whitening agents like PAP+. Blue light works by activating the PAP+ molecules, accelerating the whitening process and improving results. This combination allows faster and more effective whitening without increasing the risk of tooth sensitivity.5

Haloral’s Halo Pro Kit features both red and blue light technology, which not only whitens teeth but also promotes gum health. The addition of blue light enhances the effect of PAP+ for quicker and more noticeable results, while the red light helps reduce inflammation and promote overall oral health.

For a more targeted whitening experience, Haloral also offers the Halo Lite Kit, which uses cold blue light to whiten teeth effectively, with no discomfort.

PAP+ vs. Hydrogen Peroxide: Which Should You Choose?

When deciding between PAP+ and hydrogen peroxide, consider the following:

-Hydrogen Peroxide: If you need quick whitening results and are okay with the possibility of tooth sensitivityand enamel damage, hydrogen peroxide might be the right choice for you. However, be mindful of the potential risks with frequent use.

-PAP+: If you are looking for a gentler, long-term solution to teeth whitening with minimal sensitivity and no enamel erosion, PAP+ is a better choice. It provides comparable whitening effects while being safer for your enamel.

Conclusion

When it comes to achieving a brighter smile, PAP+ offers a safer, more enamel-friendly alternative to hydrogen peroxide. Both whitening agents are effective, but PAP+ has the edge in terms of gentleness, long-term safety, and minimal side effects. Whether you're looking for a solution that protects your enamel or a whitening treatment that reduces sensitivity, PAP+ provides an excellent option.

If you’re considering PAP+ for your teeth whitening needs, look for products that combine advanced whitening technology with safe and effective ingredients. For a gentle, effective, and enamel-safe whitening solution, PAP+ is the future of teeth whitening.
