What Are Teeth Whitening Pens?

Teeth whitening pens are a type of over-the-counter dental product designed to help whiten and brighten teeth. They are a convenient and portable option for those looking to improve the appearance of their teeth by reducing stains and discoloration.

How Teeth Whitening Pens Work

Here’s what you need to know about using teeth whitening pens.


Teeth whitening pens typically consist of a small, pen-like applicator filled with a whitening gel or solution. The gel usually contains a bleaching agent, most commonly hydrogen peroxide or carbamide peroxide, which helps break down and remove surface stains on the teeth.


To use a teeth whitening pen, you’ll simply twist the bottom or click a button to dispense a small amount of the whitening gel onto the brush or applicator tip. Then, you apply the gel directly to your teeth, targeting the areas you want to whiten. Some pens have a brush, while others have a sponge or silicone tip for application.


After applying the gel, it’s important to let it dry on your teeth, usually around 30 seconds to a minute. During this time, you should avoid eating, drinking, or rinsing your mouth.


Depending on the product and your desired level of whitening, you may need to repeat the application process daily for a certain period, often ranging from a few days to a few weeks.

Benefits of Teeth Whitening Pens

There are numerous benefits to using teeth whitening pens. A few are listed below.


Teeth whitening pens are small and easy to carry, making them a convenient option for on-the-go touch-ups.


The pen applicator allows for precise application, so you can target specific teeth or areas that need whitening.

No Mess

Teeth whitening pens are relatively mess-free compared to some other teeth whitening methods like trays or strips.

Low Sensitivity

Many teeth whitening pens use lower concentrations of whitening agents, which may result in less tooth sensitivity compared to stronger treatments.


Teeth whitening pens are often more affordable than professional dental treatments like in-office whitening procedures.

It’s essential to keep in mind that the effectiveness of teeth whitening pens can vary from person to person, and the degree of whitening achieved may not be as dramatic as with professional dental treatments.

What Should You Look for When Shopping for a Teeth Whitening Pen?

When shopping for a teeth whitening pen, you should consider several factors to ensure you choose a product that is safe, effective, and suitable for your specific needs.

Here are some key factors to look for when selecting a teeth whitening pen.

Whitening Ingredients

Check the ingredients list to see what whitening agent is used in the pen’s gel. The most common ingredients are hydrogen peroxide and carbamide peroxide. Higher concentrations generally lead to more significant whitening effects, but they may also increase the risk of tooth sensitivity.

Concentration Strength

Whitening pens come in various concentration strengths, typically ranging from 6% to 22% hydrogen peroxide or equivalent carbamide peroxide. Consider your sensitivity level and how quickly you want to see results when choosing the concentration. If you have sensitive teeth, it’s often best to start with a lower concentration.

Application Method

Look at the pen’s applicator tip or brush. A precision applicator can help you target specific teeth or areas with greater accuracy. Consider the ease of use and how well it allows you to apply the gel evenly.

Instructions and Duration

Carefully read the product’s instructions for usage. Pay attention to the recommended application duration and frequency. Some pens require daily use for a week or more to achieve desired results, while others may offer quicker results with fewer applications.

Safety and Sensitivity

Consider your tooth sensitivity level. Some teeth whitening pens are designed to be gentle on teeth and gums, while others may be more abrasive. If you have sensitive teeth or pre-existing dental conditions, choose a product that is formulated to minimize sensitivity.

Ease of Use

Evaluate how easy it is to use the pen, including the twist or click mechanism to dispense the gel. A user-friendly design can make the application process more convenient.

Price and Value

Compare the price of the teeth whitening pen to your budget. Keep in mind that more expensive pens may not always provide better results, so balance cost with effectiveness.

Brand Reputation

Consider purchasing from reputable brands with positive reviews and a history of safe and effective teeth whitening products. Research customer feedback and check for endorsements by dental professionals, if available.

Expiration Date

Check the expiration date to ensure that the product is still effective and safe to use.

Before starting any teeth whitening treatment, it’s a good idea to consult with a dentist, especially if you have concerns about tooth sensitivity or dental health. They can provide personalized recommendations and address any questions or concerns you may have about teeth whitening products and methods.

How Much Do Teeth Whitening Pens Cost?

The cost of teeth whitening pens can vary widely depending on several factors, including the brand, the concentration of whitening ingredients, the number of pens included in a package, and where you purchase them.

Here’s a general price guide to give you an idea of what to expect.

Budget Options

Teeth whitening pens with lower concentrations of whitening agents (around 6% to 10% hydrogen peroxide or equivalent carbamide peroxide) and basic applicators can cost as little as $5 to $15 for a single pen.

Mid-Range Options

Whitening pens with moderate concentrations (around 10% to 15% hydrogen peroxide or equivalent) and slightly more advanced applicators may be priced between $15 to $30 per pen or in packs of two or more.

Premium Options

Teeth whitening pens with higher concentrations (around 16% to 22% hydrogen peroxide or equivalent) and precision applicators can range from $30 to $50 or more per pen.

Professional and Custom Options

Some professional-grade teeth whitening pens, often used by dental practitioners, may cost more and may only be available through a dental office. These can be significantly more expensive, depending on the brand and formulation.

Keep in mind that you may find package deals or discounts when purchasing multiple pens together, which can help lower the per-pen cost. Additionally, prices may vary based on your location, the retailer you choose, and any ongoing promotions or sales.

While budget-friendly teeth whitening pens can provide satisfactory results for some people, it’s essential to balance cost with effectiveness and safety. Cheaper options may have lower concentrations of active ingredients and may not produce results as quickly or as dramatically as higher-priced pens. They may also have a shorter shelf life.
