Professional Teeth Whitening or Over the Counter Kits—Which One’s Better?

Professional Teeth Whitening or Over the Counter Kits—Which One’s Better?

Planning to have teeth whitening treatment done to enhance your already beautiful smile?


If you’re like most people, you’re probably wondering which of the two prevalent treatment options to go for — professional teeth whitening or an at-home teeth whitening kit?

Today, we’ll be looking at the difference between professional teeth whitening and DIY teeth whitening, and how the two compare.

How good are over-the-counter teeth whitening products?

In short, over-the-counter (OTC) teeth whitening products get the job done, but they do leave something to be desired.

The pros are that they’re cheap, easy to get, and you don’t really have to go through the hassle of setting up an appointment with your dentist to have your teeth whitened.

The cons? Well, there’s only one; they aren’t as effective as whitening treatments performed by dentists.

The reason?

It’s in the formulation of these products!

Comparing the two

OTC teeth whitening products typically use carbamide peroxide for brightening teeth. In contrast, dentists use hydrogen peroxide for teeth whitening.

Compared to hydrogen peroxide, carbamide peroxide is less effective at removing stains from the surface of the teeth. As a result, it can take weeks, and sometimes even months to achieve your teeth whitening goals with OTC products.

This also means that you may end up spending more money in the long run than what you’d spend if you choose to get your teeth professionally whitened by a dentist.

So why don’t kit manufacturers simply use hydrogen peroxide in their products?

That’s because they couldn’t do so even if they  wanted to!

Hydrogen peroxide is a highly unstable compound; it quickly breaks down the moment it’s exposed to heat or saliva. As such, using hydrogen peroxide in OTC teeth whitening products is simply an impractical solution for manufacturers.

How are dentists able to use hydrogen peroxide for teeth whitening?

Dentists use hydrogen peroxide in conjunction with UV/laser light when performing teeth whitening. This speeds up the treatment process and helps guarantee lasting results.

So if you’re looking for the best and effective teeth whitening treatment on the market, getting your teeth whitened by a dentist is the way to go.
