Pros
ConsThe details
An easy-to-use formula made for all tooth types, this Colgate Optic White Pen works gently and keeps teeth safe. So much so, that is it even recommended for people wearing crowns without any risk of irritation or sensitivity.
Effectiveness
The unique overnight formula sticks to your teeth after its nightly application and successfully penetrates past surface stains to give deeper whitening results than many of its competitors.
The all-night duration is also much longer than other pens that you use for a mere few minutes.
In the morning, simply remove the whitening gel by brushing your teeth and see the difference.
Most users start noticing results after the first few days of use and its full effects can be observed after 3 weeks of regular use.
Features
This product features a quick-dry formula that doesn’t become inconvenient.
Designed to be used alongside the Colgate Optic Whitening Toothbrush, you apply the whitening gel at night and then brush it off in the morning with your toothbrush.
Safety
This product is safe to be used with the majority of consumers reviewing that they had no problem using it.
That being said, the overnight serum can cause a little irritation to people who are not comfortable with something in their mouth all the time. But if you are not scared of that, this pen would help you achieve your dream smile.
Value for money
The low-cost Colgate Optic White shows results in 7 days but has enough gel to be used for as many as 35 sessions. It provides true value to your money and gives you the results you want.
Final verdict
If you’re looking for an effective DIY tool for teeth whitening, then the Colgate Optic White Whitening Pen is a perfect candidate but demands a fair degree of commitment. People who don’t mind using an overnight treatment will like the results they get.
For others who don’t feel comfortable sleeping with a whitening solution in their mouth, this product may hold no or very little appeal.
