Hassle-free teeth whitening pens to refresh your smile on the go

Don't want to worry about waiting for it to work or having to rinse it before you leave the house? The Colgate Max White Overnight Teeth Whitening Pen has been designed to be used overnight and can reportedly reverse 15 years of discolouration caused by food and drink in three weeks. Each pen has a precise applicator brush and contains 35 nightly treatments with the active ingredient being hydrogen peroxide.

Our review: “I have really sensitive teeth that even some toothpastes can cause me mild pain, so I’m mindful about what products I use. I didn’t feel any discomfort while using this pen and I love how it works overnight so you don’t even notice that you’ve got it on. It is super easy to apply, you just need to click it a couple of times until you see the product come out the end of the brush and then cover your teeth with a thin layer. I’ve been using it every night for over a month now and have started to notice the improvements to the discolouration on my teeth. If you're looking for a product that is going to subtly whiten your teeth over time, this is a great option.”

Created by dentists Dr Lisa and Dr Vanessa, this clinically formulated whitening pen is designed to work in as little as 20 minutes. Formulated with the ingredient hydrogen peroxide, the easy-apply formula actively dissolves stains for long-lasting results without causing sensitivity or harm to tooth health. Use Spotlight oral care daily, on the go, or as a top-up after other whitening treatments.

Customer review: "Just amazing and really made a considerable difference in a really short space of time."

We've all heard of the Kardashians, and while we're sure they're using much more expensive teeth whitening treatments, this whitening pen from MOON x Kendall Jenner should help your smile feel a little brighter on a budget. Designed to brighten your smile and work on tough stains, the 100 per cent vegan formula uses a lovely vanilla mint flavour for lasting freshness. It's recommended to use it twice a day for a maximum of two weeks at a time.

Customer review: "I was not expecting this to work because whitening pens have not been great in the past but this really did whiten my teeth to the point that other people noticed. Nice packaging, easy to use and effective!"

Described as the 'first beauty serum for teeth and gums', this is another overnight whitening treatment with added healthy teeth benefits. With Pearl Drops' patented Liquid Calcium technology, the surface enamel is strengthened against acid erosion, lost gloss is restored, and the active oxygen gives an extra boost to whiteness lost over time. It also includes gum and enamel-friendly vitamin E and refreshing mint oils and is safe for everyday use.

Customer review: "It was a pleasure to use the pearl drops whitening pen and toothpaste. I saw a noticeable difference after the first use, my teeth are stained as I'm a tea/coffee drinker. Easy to use, pleasant taste and effective results, I believe with continuous use my teeth will be a few shades whiter."
