Teeth whitening pens are another method of applying peroxide-based gel. Some users prefer pens because they’re less messy than whitening trays or paint-on products. It can be a very good touch-up method when at home or while travelling.
Teeth whitening pens apply the gel conveniently by just twisting up some of the product and applying to the teeth. The pen can be used at night or during the day, as needed. The gel in pens is similar to that used with trays in that it can contain up to 44% carbamide peroxide.
Some users find that they see results in as little as two days depending on the concentration and type of peroxide. For faster results, some users have found that repeating the application instructions every 10 minutes for 1 or 2 hours was effective although this is not recommended for those pens with stronger concentrations of peroxide. Whitening pens are perfect for touching-up in between other whitening methods, or treating stains in a particular spot.
Pros and Cons
The main advantage of whitening pens is that they can tossed in a purse, backpack, suitcase or travel pouch to touch-up on-the-go. Many users also like their ease of use even compared to paint-on applications. Simply turn the bottom of the pen to push up the whitening product and apply the gel to your teeth.
Perhaps the main disadvantage to pens is that they have a limited reservoir. Even though some can have up to 50 touch-up uses in them, you’ll probably get two maybe three full applications’ worth before it is empty. So it may not be the most cost effective solution for a complete treatment.
Tips and Guidelines for Use
- Allow the gel to harden. The best way to do this is to keep your lips away from your teeth for 30 to 60 seconds.
- Wait before you eat. Avoid eating and drinking for at least one hour.
- Tooth Sensitivity. Stronger peroxide-based gels (22% and up) may cause tooth sensitivity and burn gums if it comes in contact with them.
