Do teeth whitening pens work?

Teeth whitening pens and results can vary but for the most part, teeth whitening pens are effective teeth stain removers and will help you with achieving whiter teeth. However, it’s worth keeping in mind that this type of home whitening won’t provide a permanent solution. It’ll work well in the short term when used as a maintenance tool, but for more effective, long-lasting results, you so should investigate other options such as kits and strips.

How to use a whitening pen:

Application instructions can vary with different teeth whitening pens, but for the most part, the process is super easy:

  1. Twist the pen to dispense gel onto the application brush
  1. Use the brush to paint the whitening gel onto your teeth
  1. Leave in place for five to 30 minutes (dependent on the pen)
  1. Rinse your mouth to remove excess gel
  1. Use daily to maintain whitening effects

How long does it take to whiten teeth with a whitening pen?

The results of a teeth whitening pen can appear in as little as a matter of days to a couple of weeks.

How often should you use a whitening pen?

Different pens have different requirements, and you should read the instructions for your chosen whitening pen before beginning with the treatment. For example, the Moon Kendall Jenner Teeth Whitening Pen is advised for use for a maximum of two times a day for two weeks whilst the Spotlight Oral Care Teeth Whitening Pen recommends an ongoing daily treatment.

Are whitening pens safe?

Whitening pens are generally safe to use, so long as you use them as outlined and check for any safety advice. For example, some kits are not suitable for anyone under the age of 12 and can’t be used if you are pregnant or have existing dental concerns such as ulcers or exposed gums.

As with any form of at-home teeth whitening, some side effects can include tooth sensitivity, gum irritation, and damage to the tooth enamel if overused.

Always do your research before purchasing and check the ingredients list for gentle ingredients or a low concentration of harsh bleach, and for any known allergies. And, of course, if irritation occurs, stop using the treatment. It’s recommended to seek advice from your dentist before undertaking new treatments if you’re in any doubt or you’re concerned about the sensitivity of your teeth.

Looking for longer-lasting results? A teeth whitening kit may be what you're looking for as they usually come with a mouth guard, activating solution, a syringe of gel, and a UV light to help you achieve a more dazzling smile at home.
