The best teeth whitening kits freshen your breath too

While all teeth whitening products may seem alike, there are critical differences that place some specialty products on a higher echelon than their common, ineffective counterparts. What is it that makes the best teeth whitening kits a cut above the rest?

For one thing, the most useful teeth whitening products are gel-based. This may not seem like it would make all that much difference, but are you willing to wager your teeth on it? It's an ironclad rule, really: gel-based teeth whitening tools can get the job done right, while others may leave you with dappled, pied or blotchy teeth. Here's why.

Cheap teeth whiteners usually come in two forms - namely, strips or brush-on paste. The paste works well enough, but such products usually rely on this goo fully drying. If you happen to close your mouth or swallow, you may rinse away some of the paste leaving you with one or more yellow teeth standing out of your dental line-up.

Strips are just as bad, and today they're quite popular. Unlike the best teeth whitening gels, strips do not get any of the bleaching agent between your teeth. Are you starting to see why that might be a bad thing? Unless you want teeth that look like white bricks separated by yellow mortar, skip the strips and use specialty gels.

But not just any gels will do. The best teeth whitening kits use moldable trays to deliver bleaching gel evenly across and between all of your teeth. They also utilize gels that are not based on glycerin to prevent your teeth from being sensitized.

Rather than risk having less-than-white pearly whites, consider buying specialty teeth whitening kits that use trays and gels to bleach your chompers evenly.
