Getting your teeth professionally whitened by your dentist is time-consuming and expensive. Instead of filling your calendar full of dentist appointments, you can achieve significant teeth whitening results in the comfort of your own home with teeth whitening pens.

The best teeth whitening pens are easy to use and promise to help you keep your teeth bright and stain-free. Keep in mind that a teeth whitening pen does not replace a regular toothbrush and toothpaste when it comes to cleaning your teeth — think of a whitening pen as an added step in your oral care routine.

How Does a Teeth Whitening Pen Work?

After you brush your teeth (and your teeth and gums are relatively dry), remove the cap from your teeth whitening pen and twist the bottom of the pen until the brush tip is coated in teeth whitening serum. When it comes to the best teeth whitening pens, this serum will take the form of a gel with the active ingredient being hydrogen peroxide or carbamide peroxide.

Once the tip of the brush is coated, apply a layer of the whitening gel to each tooth’s surface. For best results, make sure that the entire tooth’s surface comes into direct contact with the whitening gel. Once each tooth is treated, do not rinse your teeth. You must defer to the teeth whitening pen’s specific instructions in order to determine when it’s time to rise.

For some teeth whitening pens, you will leave the gel on overnight. For others, there is a specific wait time that can range from five to thirty minutes. Both overnight and non-overnight serums are effective – the best teeth whitening pen for you will have a leave-on duration that is compatible with your own oral care routine (and general comfort level).

What Are the Best Teeth Whitening Pens?

When shopping for the best teeth whitening pens, it is important to take stock of your oral care needs. If you are curious about at-home whitening and want to give it a try, it’s best to turn to a trusted oral care brand. You don’t necessarily need to stock up on teeth whitening pens from the very start. However, if you are serious about your teeth whitening routine and are ready to fully commit, you’ll want to purchase teeth whitening pens in value packs. Some packs even have enough pens to give you a full year’s worth of treatment. Lastly, know your teeth. If you are someone who has to use toothpaste for sensitive teeth, then you’ll want a teeth whitening pen that’s designed for sensitive teeth, too.

1. Colgate Optic White Overnight Whitening Pen

If you’re new to at-home teeth whitening, turn to the brand that you trust to take care of your everyday oral care: Colgate. The brand says its Overnight Teeth Whitening Pen can remove up to fifteen years worth of stains from your teeth in only one week when used properly.

The whitening gel formula must be left on your teeth overnight and contains 3% hydrogen peroxide, but we didn’t really notice any irritation or annoyance as long as the gel is rubbed into the teeth rather than left dripping.

The whitening gel is also vegan, gluten-free, and sugar-free. Each pen has enough gel for 35 nightly treatments.

2. Beaueli Teeth Whitening Pen

If you have sensitive teeth and gums, the Beauelo teeth whitening pen is the best option for you. Its gentle and effective formula is made with 35% carbamide peroxide, natural mint flavor, and glycerin drops.

After seven days of use, twice a day, you should see noticeable results. The whitening gel does not need to be left in overnight. However, you should avoid eating or drinking for thirty minutes after you use them. These pens are sold in packs of three.

3. Soniultra Teeth Whitening Pen

You want the best of both worlds: Skip the dentist, but get professional-grade results. The Soniultra pens help you achieve just that. The brand says that tough stains caused by coffee, wine, smoking, tea, and soda can be reduced with consistent pen use, and the result is a smile 4-8 shades brighter than before.

For noticeable results in our experience, the pen must be used two times a day and the gel must be left on your teeth for thirty minutes each time. Its formula contains 35% carbamide peroxide and is gentle on your teeth. Sold in packs of four, these teeth whitening pens will become a staple in your everyday oral care routine.

4. Smile Direct Club Teeth Whitening Pens

For those who like to buy in bulk, the Smile Direct Club teeth whitening pens are sold in an eight-pack, which equals a full year’s worth of teeth whitening pen use. The pens contain a hydrogen peroxide-based serum and promise that your teeth will become nine shades whiter in one week if used properly. Proper use includes using the pens twice a day and leaving the gel on your teeth for five minutes each time. Four pens amount to six months of visible results, which means this eight pack offers you a full year with a whiter, brighter smile.
