    Whitening your teeth used to mean costly dental visits, hours with trays in your mouth, and sticky strips. In recent decades, dozens of more affordable and effective products have flooded dental care aisles, but none more buzzed about than teeth whitening pens. Teeth whitening pens are uber-popular for a good reason: they are nearly foolproof and dispense whitening gel directly onto teeth in mere seconds, offering a way to touch up after coffee and between meals. What’s more, the compact design of teeth whitening pens makes them perfect for on-the-go use.

    While whitening pens are not as effective asprofessional treatments and require consistent use to yield results, they are great for those who can’t commit to a lengthy whitening routine. Those who have already whitened with a whitening kit or an in-office treatment may also find that a whitening pen is the perfect way to maintain results and touch-up between treatments. With so many teeth whitening pens available, it can be difficult to know which one is the best fit for you. Keep reading to see our rankings for the best teeth whitening pens for a glowing smile.


    How to Choose a Whitening Pen

    Though many whitening pens look similar, not all whitening pens are created equal. When selecting a whitening pen to integrate into your whitening routine, it’s important to take into consideration the whitening gel formula and taste, mode of application, and brush tip, as well as how easy it is to use. 

    The Formula

    In order to truly whiten teeth and not just buff away stains, a whitening pen must contain an active whitening ingredient. Most whitening pens contain low-concentration hydrogen peroxide or carbamide peroxide, which is a mixture of hydrogen peroxide and urea. Both active ingredients have been shown to visibly whiten teeth safely. Those who are vegan or have food sensitivities should also consider the ingredient list of whitening pens and look for a formula that is free of animal products, soy, or other sensitivities. 


    When considering a whitening pen, don’t forget about taste! The whitening gel will be applied to your teeth and should be allowed to ‘set’ before eating or drinking, and many pens don’t require rinsing. For this reason, you should consider taste when picking the pen that is right for you. Most pens have a slightly minty taste that can turn whitening into a pleasurable self-care moment.

    The Application

    The general application of teeth whitening pens is the same - turn a dial or click a button to dispense the whitening gel, then use the brush or tip to apply to teeth. Some pens have flexible, paintbrush-like tips, while others have a silicone wand or spatula that spreads the gel onto enamel. It’s important to look for an applicator that has antimicrobial properties that inhibit the growth of bacteria, and a pen that is easy to use.
