When you're looking for the right way to brighten your smile, you want the best teeth whitening reviews you can find. That means finding reviews that aren't being paid to be reviews. Let's take a look at what that means...

Reviews are simply statements about a product given by people who have used that product, as opposed to endorsements or marketing copy -- which can look like reviews, but aren't.

Any intelligent consumer reads the reviews of teeth whitening products before deciding which to invest in -- but even the smarter purchasers aren't necessarily able to spot the difference between teeth whitening reviews and pieces of advertising disguised as teeth whitening reviews.

These reviews are a critical necessity in the teeth-whitening arena because there are so many products that are advertising so heavily with marketing-oriented articles and endorsements.

Many of these products are fairly expensive -- between forty and four hundred dollars -- so it's not an investment to enter into lightly. That's why getting the right teeth whitening reviews is so critical.

So, how can you tell a marketing attempt from an honest review? Well, there's a few simple ways.

If a review discusses the downsides of a product, and then offers an alternative at the end, it's usually a marketing attempt. Similarly, if a review only talks about the benefits and features of a product, without ever mentioning a downside, and then offers a link to a sales page -- its only purpose is to sell to you.

In fact, any teeth whitening reviews that offer only a single sales link (or multiple links to the same product) are probably trying to sell you something.

Realistically, unless you can find a certified comparative product review from an independent laboratory, you're going to have to look long and hard for honest, spontaneous statements about a product's quality.

The only good way I've found is to go to Google and type the product's name, in quotes, followed by '+inurl:forum'. This finds only forums, which tend to be freer of all but the most transparent marketing attempts than most of the Web.

Your other option, of course, is to try the products for yourself and see if they work for you.

This can get expensive, unless you have a product with a free trial, like (this one, for example) or a product with a money back guarantee if you don't like it (like this one.)

But if you can afford these free trials, you'll have the best teeth whitening reviews you'll ever read: your own.
