How Does a Teeth Whitening Pen Work?

Whitening pens are great when it comes to whitening specific areas of the mouth, convenience, and quick whitening results. But how do whitening pens work? Well, it all comes down to the different tooth bleaching agents used, the formulation, and application process. Here’s everything you need to know about how these leave-on treatments brighten up your smile and if they’re safe for daily use.

Teeth Whitening Pen Active Whitening Ingredients

Whitening pens all use some form of peroxide as their main whitening agent, whether it’s hydrogen peroxide or carbamide peroxide. There’s no significant difference across these two ingredients when it comes to whitening effectiveness, however, the way that agent is formulated into the whitening serum can affect sensitivity and how quickly that whitening solution works.

Teeth Whitening Pen Formulas

Most teeth whitening pens are designed to give your smile a quick pick me up when it comes to brightening. However, they rely on the peroxide agent used to deliver those results—which can lead to sensitivity. When picking the whitening pen that’s right for you be sure to look for one that’s both effective and gentle on teeth and gums.

Crest Whitening Emulsions is formulated differently than other whitening pens. That’s because the unique serum features highly active peroxide droplets suspended in a water-resistant base which whitens teeth with virtually no sensitivity. The enamel-safe formula is guaranteed to deliver better, faster, 100% whiter teeth*.

How To Use a Teeth Whitening Pen

Depending on how the serum is packaged, the application process can differ across various teeth whitening pens. Some whitening pens come with a separate brush that you use to simply swipe on individual teeth and back teeth. Others are developed to be portable, so you can squeeze the tube and apply the whitening solution on-the-go.

Crest Whitening Emulsions offers up both these options, and then some:

  • Crest Whitening Emulsions with Wand Applicator: Perfect for a more controlled and precise whitening experience, the soft-tipped wand can cover individual teeth, more stained areas, and even your back teeth. Just squeeze the whitening serum onto the wand, brush on teeth, and you’re good to go.
  • Crest Whitening Emulsions with LED Light: Inspired by the same technology that dentists use to professionally whiten teeth, the LED teeth whitening light safely penetrates the tooth’s enamel surface to quickly break down tough stains. This helps deliver more effective and faster whitening than just using Emulsions alone.
  • Crest Whitening Emulsions with Built-in Applicator: Specifically designed for portability, the built-in applicator allows you to whiten your smile from wherever, whenever. Plus, it can be applied in just mere seconds and there’s no need to rinse, brush, or remove anything afterward. For even more effective whitening results, you can apply Emulsions up to 4X a day!

To continue to maintain a bright and healthy smile it’s important to follow a thorough, daily oral hygiene routine of brushing 2X/day for 2 minutes and flossing at least 1X/day. Make sure to visit your dental professional at least 2X a year for professional cleanings and checkups.
