How it's work
Share
A teeth whitening essence pen typically contains a whitening gel that is applied directly to the teeth using a brush tip. Here's how it generally works:
-
Active Ingredients: Most whitening pens contain hydrogen peroxide or carbamide peroxide, which are common whitening agents. These compounds penetrate the enamel and break down stains.
-
Application: You twist the pen to release a small amount of gel onto the brush tip, then apply it to the teeth. It’s usually recommended to cover the surface of the teeth evenly.
-
Activation: Some products may require a certain amount of time to sit on the teeth before rinsing, while others can be left on to dry. The gel typically needs to be in contact with the teeth for a specific duration to be effective.
-
Frequency: For optimal results, the pen is often used daily for a specified period, usually a couple of weeks.
-
Results: With consistent use, many users can see a noticeable difference in the whiteness of their teeth, often within a few days to weeks.
Always follow the instructions provided with the product, and consult a dentist if you have concerns about teeth sensitivity or other issues.
