Product ReviewsColgate Optic White Overnight Teeth Whitening Hydrogen Peroxide Gel Pen - 0.08 fl oz

Easy to use, quick results

This pen is so easy to use. Just click it and 'draw' on your teeth before bedtime. In the morning just brush your teeth as normal. Within a week you will notice whiter teeth. I had one stubborn stain between two lower teeth in front that I can never remove. After just a couple days of using this pen the stain was gone! My teeth are very nice and bright white now. The pen can be used for several applications as you only need to use it for one week at a time. Much easier and more comfortable to use than the whitening strips.Read full review...

Chalky Mess

I am not happy with the consistency of the product The pen tip gets hard and chalky after the first use When reading the booklet there are a lot of do and don’t s to follow and after following all the directions the tip still is hard and chalky I do see a slight improvement in my color I bought this because it was a very good price I have use other whitening pens and they glide on smooth and clear and the tip stays clean after whipping it with a tissue Overall I will probably not purchase this item again Read full review...

Great Brand

Easy to use. It worth a try. You can’t go wrong with Colgate products. I decide to try the Colgate Optic overnight teeth whitening pens because I trust the Colgate brand.

Not quite white

This stuff is supposed to be great….I found it hard to use, and no more effective, and much less convenient, than less expensive alternatives. The application brush broke after two uses…

Great for quick results

great price, but as far as using it, not pleased using it. Didn't realize that this only does the front teeth, Also, no drinking anything during the application time (night time) I am a tray user and more comfortable with them Read full review...

Good product, poor delivery system.

The pen takes forever to produce any product, then the brush seems to limit good access to the teeth, and tip gets clogged. Product seems somewhat effective, but very 'clotty'.

Terrible product......doesn’t work. It will barely come out of the tube aan odd texture. Would never buy again. Can’t believe Colgate put out a

Terrible product......what comes out of the tube is an odd stiff texture that won’t spread on your teeth. It doesn’t work period.

Works as Advertised

This teeth whitening product is quick and easy to use, with intended results seen after the first or second application. When the applicator is empty I will order another.

Works but frustrating applicator design.

This stuff does work. The pen application needs to be completely redesigned. If you can keep it working long enough to use up the tiny amount they give you, you'll notice the whiter teeth.

Good Product

Works well- I use it under my Invisilign retainers. My teeth look whiter for sure and it's easy to remove it with a tooth brush in the morning. I have not had any sensitivity with this product.
