Do teeth whitening pens work?
“Absolutely! It’s all about three things,” Twice’s chief dental officer, Jonathan Levine, explains. First is “the frequency of use (consistency is key!),” he says. Then it comes down to the concentration of the active ingredient, hydrogen peroxide. And finally, “the adhesive that the hydrogen peroxide is formulated with that keeps it on the teeth.”
Do teeth whitening strips, pens, or kits work best?
Ultimately, it’s whatever product application you prefer. Some users don’t like the feeling of strips, while others think pens aren’t as effective. All of that said, “The best whitening occurs when the active gel, hydrogen peroxide, is accelerated by warming or heat such as it is in the GLO Science Brilliant Whitening Device,” Levine adds.
How often should you use a teeth whitening pen?
Generally, you can use the pen daily, but it’s important to read the instructions (and pay attention to any sensitivity). “You can use it often to remove new stains every day, depending on the concentration of the whitening gel,” Levine says. “For typical whitening products, maintenance is dependent on how much red wine, coffee, or tea that the patient ingests. It is safe to use up to three to five times a week, not to exceed.”
However, some products can be used more or less depending on the formula and your tolerance. “For the Twice Oral Wellness Whitening Pen, we recommend one to two times a day for 14 days, and then three to five times a week for maintenance,” Levine says.
