A bright, white smile is important for making positive first impressions and boosting self-confidence. However, many Americans are unhappy with the color of their teeth. According to a 2016 article in “Operative Dentistry,” over one-third of people in the U.S. are dissatisfied with their tooth shades. Thankfully, today more accessible and affordable at-home teeth whitening options exist for those seeking an easy fix between professional treatments. 

One popular over-the-counter product is the Moon Teeth Whitening Pen, a convenient whitening pen applicator co-created with celebrity Kendall Jenner. Touted for its gentle peroxide-based formula that lifts stains quickly, this vegan pen aims to make touch-up whitening simple without a hefty price tag or hassles. Let’s dive into the details and explore what this product has to offer.

What Is Moon Whitening Pen?

The Moon Whitening Pen is an at-home cosmetic dental product designed for teeth whitening. Co-created with celebrity Kendall Jenner and manufactured in the USA, this pen applicator contains a whitening gel formula aimed at safely removing surface stains from teeth. The product retails for around $20, and over one million units have been sold since its launch.

In 2023, the Moon Whitening Pen received an award from NewBeauty magazine in the Best Teeth Whitening Pen category. The whitening formula features light-reflecting pigments for immediate teeth brightening and gentle urea peroxide for gradual, safe whitening. It has a pleasant minty flavor and is free of harsh chemicals and artificial flavors, and is made to be suitable for those with sensitive teeth.

PROs and CONs of Moon Teeth Whitening Pen

The Moon Whitening Pen has several beneficial features as an at-home teeth whitening product, but also some potential drawbacks to consider.

PROs

On the positive side, the pen applicator allows easy and convenient application directly to teeth. At around $20 retail, it is affordably priced compared to professional whitening procedures. Its whitening gel ingredients create visible brightening effects after just the first use for many customers. The whitening formula is free of harsh chemicals, ingredients like SLS, SLES, parabens, and artificial flavors. It is also vegan-friendly and cruelty-free. The peroxide concentration aims to lift stains safely even for those with some sensitivity. Gentle on enamel, it can whiten wine, coffee, and tea discoloration. 

  • Easy application
  • Affordable price
  • Effects visible after the first use
  • Pleasant vanilla-mint flavor 
  • Free of SLS, SLES, parabens, and artificial flavors
  • Vegan and cruelty-free
  • Gentle on teeth
  • Safe for sensitive teeth
  • Works on wine and coffee stains
  • Tried and tested by over a million customers
  • Made in the USA

CONs

However, as a peroxide-based whitener, users may experience tooth or gum sensitivity during the first few applications. Drinking heavily pigmented beverages is also not recommended during use as staining could counteract the brightening benefits. While effective for mild stains, the pen may not produce dramatic changes for severely yellowed or discolored teeth.

  • Can cause tooth sensitivity, especially during the first use
  • Drinking staining drinks such as coffee and tea while using this product is not advisable
  • Will not whiten severe discolorations

Who Is a Candidate for Moon Whitening Pen?

The Moon Whitening Pen is designed as a teeth whitening product suitable for those with mild to moderate discoloration looking to brighten their smile. Those seeking dramatic brightening of very yellowed or stained teeth may require different products or procedures for satisfactory improvement.

Its formula is considered safe for people with sensitive teeth when applied as directed. As a vegan product free of harsh ingredients, the pen aims to whiten teeth without excessive sensitivity.

It is not recommended for use by children under the age of 12. The whitening gel is also only intended for application directly onto natural teeth, meaning it won’t be effective on crowns, veneers, or fillings. While effective in removing surface stains, its results may vary for individuals with more severe, deep-set discolorations or darker tooth shades to start. 

How Does Moon Whitening Pen Work?

The Moon Whitening Pen has an easy application process. First, the protective cap is removed to expose the brush applicator tip. The user presses the button at the end of the pen repeatedly until the whitening gel is dispensed onto the built-in brush. Several clicks may be required on first use to properly prime the pen. Once gel appears on the brush, the user brushes a thin, even layer onto the tooth surfaces. The instructions then advise waiting 30 seconds with mouth open before closing and allowing the gel to whiten for 10-30 minutes before eating or drinking.

For maximum whitening effectiveness, the pen can be applied up to two times per day for two weeks. Use beyond 14 days is only recommended under the supervision of a dentist. The company recommends avoiding heavily pigmented foods and drinks like coffee, tea, red wine, etc. during this time to maintain results.

It is important to avoid swallowing the formula or contact with the eyes. Users should also minimize contact with gums and tongues. 

How Much Does Moon Whitening Pen Cost?

The Moon Whitening Pen retails for $19.99 per unit. This positions its price point comparably to other at-home teeth whitening pen products on the market. It offers a more budget-friendly option than higher priced processes like professional whitening treatments or custom-fit whitening trays paired with gel.

Are There Any Side Effects?

Like any teeth whitening product, there is a possibility of side effects occurring with use of the Moon Whitening Pen. It contains the active ingredient urea peroxide, which works to remove deep set stains but may cause temporary tooth sensitivity in some users. Overuse or extended/prolonged applications beyond the recommended guidelines can also risk potential damage to tooth enamel or irritation of the gums.

As with any cosmetic dental product, users are advised to carefully follow package directions and heed any warnings regarding application time or frequency. Consulting a dentist in advance can help identify any pre-existing sensitivity or gum issues that could be aggravated by a peroxide-based whitener. Stopping use and speaking with your dentist if problems develop can prevent more lasting effects.

Does Moon Whitening Pen Really Work? Customer Reviews

Based on multiple customer reviews, the Moon Whitening Pen appears to effectively whiten teeth for many users, but experiences vary. Positive reviews mention visible brightening after just a couple of uses. The pen applicator makes touch-up whitening simple and fast. Users note fresh stains from coffee or wine wipe off easily with reapplication.

While many observe instantly brighter teeth on application, a number find the whitening effects temporary or not as dramatic as expected. Individual experiences differ depending on starting tooth shade and diligence in the application. Criticisms include the pen clogging or dispensing inconsistently, and some dislike the taste. 

In general, customer opinions on the effectiveness of the Moon Whitening Pen range widely. When it works as intended, the majority see a noticeable improvement in tooth shade after consistent use. But it may not yield dramatic brightening for those starting with severe discoloration.

Verdict

The Moon Whitening Pen offers a budget-friendly, convenient option for those seeking touch-ups between professional whitening treatments. The easy click-pen applicator allows direct spot treatment for quick brightening of surface stains on teeth. Customers report visible lightening after just initial uses.

However, as an over-the-counter peroxide whitener, the Moon Pen must be used carefully to avoid side effects. It can temporarily increase sensitivity, especially when overused. The formula also may not work well for severely discolored teeth. Results depend on stain type and proper consistent application.

For mildly yellowed teeth, the pen can provide a satisfactory boost. But dramatic whitening should not be expected from this home product. Those with sensitivities or highly pigmented staining may be better served consulting a dentist for something more powerful.
