Toothpaste that claims to whiten your teeth is one of the first steps everyone makes to try and get a whiter and brighter smile. However, these toothpastes does do not actually bleach your teeth. Instead it's more of a way to either help reduce surface stains caused by coffee, smoking, tea or foods that can stain. If you have already undergone a whitening treatment, a toothpaste is a great way to help prevent and slow down future discoloration and staining.

It Doesn't Contain Hydrogen Peroxide

Almost all whitening toothpastes do not contain hydrogen peroxide or any bleaching solution, which is the primary ingredient needed to bleach your teeth. Instead they contain mildly abrasive particles and when combined with scrubbing with a toothbrush scrub debris off the surface of your teeth. Many time they will also contain polishing agents to help give you what appears to be a brighter and whiter color.

Some Actually Have Hydrogen Peroxide

Some teeth whitening toothpastes actually have small traces of peroxide, but only at low levels. Studies have shown that teeth whitening toothpaste that does contain peroxide only deliver a 1% or less exposure of hydrogen peroxide to a tooth's surface. This low level of peroxide in combination with the fact that most people only brush their teeth approximately 30 seconds to 2 minutes only allows a brief exposure time, making any whitening effect practically impossible. If you want an effective teeth whitening solution you will need at least a 3% peroxide solution in combination of the solution being exposed to your teeth for at least 15 to 30 minutes.
