It is natural for teeth to stain over the course of time. Thankfully, there are solutions such as teeth whitening pen, gel, strips and more.

The pen usually contains a small amount of gel that contains the bleaching agent.

While the concentration of the agent may not be as strong as that in gels and strips, it can still effectively whiten your teeth for a quick touch-up.

In fact, these are best for touch-ups to get whitening on the go.

If you need a quick fix for an annoying stain here or there, a pen is all you need.

Keep reading this article to know more about how you can make use of this pen for whitening.


Why Do Teeth Stain?

Teeth stain because of extrinsic and intrinsic discoloration.

Extrinsic discoloration occurs due to eating and drinking foods that stain your teeth.

These include the likes of soy sauce, potatoes, tomato ketchup, coffee, tea, soft drinks, balsamic vinegar, red wine and more.

This heavily stained food can cause your teeth to appear darker as they stain the enamel and erode it.

Furthermore, smoking can also turn your teeth darker yellowish-brown.

All these will form surface-level stains on the front of your teeth.

Hence, a teeth whitening kit or other such products such as gels, toothpaste can work on these extrinsic stains.

However, they may not work as well on intrinsic stains.

Intrinsic discoloration happens inside the teeth.

The contributing factors are age, injury, enamel erosion, medicines and diseases.

As you age, your enamel naturally wears down.

This exposes the dentin in your tooth structure.

The dentin is naturally yellower and as you age, it gets darker.

This yellowness can also arise from an injury to your tooth whereby there’s damage to a blood vessel.

Or it could form because of treatments, diseases and medicines such as chemotherapy.

While some kits can work on intrinsic stains, a teeth whitening procedure in a dentist’s office works best on them.

Blue light with an at-home mouthguard kit can penetrate the enamel to work on the dentin but most kits will only work on the enamel.

Thus, a teeth whitening pen is best suited to correct some stains present on your tooth’s surface.

It is ideal for quick fixes and touch-ups while you are on the go.

Furthermore, it is travel-friendly and portable.

Let’s find out more about its benefits and uses below!

What is a Teeth Whitening Pen?

It is a small plastic tube that contains the bleaching agent in the form of a gel.

You twist it to release the gel through the tip which is similar to a brush tip.

It can clear your surface stains as a whitening toothpaste does however, it is much easier to use and can give quicker results.

Therefore, they are ideal for quick touchups.

Their small size is even more beneficial as it makes them travel friendly.

You can carry these portable pens on the go and quickly fix a few stains on your tooth’s surface.

Moreover, the whitening gel consists of carbamide peroxide or the bleaching agent is a mix of hydrogen peroxide and urea.

Carbamide peroxide does not whiten teeth as fast as hydrogen peroxide, however, it reduces tooth sensitivity after whitening.

What these bleaching agents do is break down your stains. This helps to make them less apparent.

As a result, your teeth look brighter than how they previously looked.

Unlike other whitening methods, a pen works almost instantly and does not require you to wait to see results.

Therefore, the pen is designed to have a small size and be portable to be a whitening product that you can consume on the go.


Benefits of Using a Teeth Whitening Pen

Easy and Convenient

This whitening treatment can fit right into your pocket.

You do not have to carry a tray, gels or toothpaste with you anywhere.

All you need to do is to slide the pen into your bag and you are good to go.

Moreover, it is easy to apply without having to set up the trays and strips.

You can apply it while you are outside even without the help of a mirror (though using that will be better).

Learn more on its application below.

Quick Results 

You do not have to wait for a long while to see results.

Rather using a pen is much quicker.

It breaks down the stains hence, they are not as visible.

You can use it right before you are going on a stage or a meeting.

The results are quick enough to show through in that amount of time.

No Waiting

Unlike using trays, strips and gels, you do not need to wait after applying the pen.

You may have to wear a tray for up to 30 minutes and need the same amount of time for strips to work.

However, you simply need to brush the pen onto your teeth.

The only thing you need to be mindful of is that you should not rinse your mouth immediately after applying it.

It works when the gel would stay on your teeth so do not accidentally rinse it off.

Once the gel dries and leaves a film on the teeth then you can rinse it off.


If you are just beginning to use whitening products then starting off with a pen is a good option.

Out of all the options available, it is probably the most affordable.

It can also complement other products and is available at your drug store.

Use and Effectiveness

If you are heading out, or need a quick touchup, all you need to do is to twist this pen.

Begin by first brushing your teeth thoroughly.

Use a brush with soft bristles and keep it at a 45-degree angle to clean all teeth.

Next, twist the pen till you see the gel appearing on the brush tip.

Carefully apply the tip on the surface of all your teeth.

Make sure that the tooth’s surface is totally covered with the gel.

Let it dry hence, do not rinse until a film forms onto your teeth.

This shows that the gel is on your teeth and it needs to stay there for the whitening to work properly.

Some pens may completely prohibit you from rinsing while others may suggest you rinse once the film forms.

Strips and trays do not reach in between your teeth and gums.

However, the pen can reach areas that are harder to access otherwise.

You can slide the tip of the pen in between the gums and interdental spaces.

These are the places where stains accumulate.

Though, it is important to note that all stains are equal.

There will be yellow, brown and even gray stains.

While using over-the-counter products you need to have realistic expectations.

While these products are good at removing yellow stains, they may not work as effectively with brown stubborn stains.

Hence, if you have stubborn brown stains then it is better to go for a professional dental whitening such as Zoom Teeth Whitening rather than trying over-the-counter products.

Moreover, you should keep in mind that this pen will not work on crowns and veneers.

If you use the pen correctly on yellow stains then you will surely see results.

While there can certainly be some shortcomings of using it.

Side Effects and Shortcomings of a Teeth Whitening Pen

  • Short term results hence cannot be a long term solution
  • Will have to abstain from drinking, earing or rinsing mouth for a while after application
  • Can decrease tooth enamel hence leading to sensitivity
  • The saliva can also break down the ingredients in the bleaching agent
  • Uneven whitening
  • Can cause gum irritation

Like every other whitening product, this can also reduce your enamel over time.

Due to that, you will have increasingly sensitive teeth afterward.

Sensitivity also occurs because of the bleaching agent contacting the dentin and irritating the nerve.

Moreover, the results of using the pen are more short-lived than any of the other treatments.

While you apply the pen, you have to be extra careful that you do not touch the gums.

The serum inside the pen can cause irritation inside your gums if the bleaching agent gets in contact with them.

Also, since you are applying on your own, there is a chance of getting an inconsistent application.

Some of your teeth may appear whiter than others because your hand may not reach as far as your molars to get even whiteness everywhere.

After the application, you will have to wait for the gel to dry and not eat or drink anything in between.

Otherwise, you will render the application useless.

Another thing that can render its use useless is how the saliva in your mouth can break down the active ingredient.

In order to get white teeth and a brighter smile, you can use teeth whitening products such as pocket-sized pens containing 35 % carbamide peroxide or less, led light and other products that will soon give visible results.

While a teeth whitening pen is a good product to use on the go and for a whiter smile, it does have these shortcomings.

Some good options in the market are AuraGlow Teeth Whitening Pen, Colgate Optic White Overnight Whitening Pen and Philips Zoom Whitening Pen.

They are also available in flavors such as vanilla or mint flavor.

Choose wisely according to your needs and sensitivity to brighten your smile.
