Can Whitening Toothpaste Really Whiten Teeth?

I usually like to drink coffee, I don't know if this is the reason, my teeth are always yellow. Can I use whitening toothpaste to whiten my teeth?

Our teeth themselves are not white, but slightly yellow.

If you often drink colored drinks such as tea and coffee, there will be pigmentation on the surface of the teeth, which will make the teeth look more yellow. This type of stain that sticks to the surface of the tooth is called extrinsic staining.

For this kind of external staining, daily brushing and regular cleaning can remove stains and make teeth clean again, not necessarily with whitening toothpaste.

But if you really want to use whitening toothpaste, you can.

Whitening toothpastescontain bleaching ingredients, the most common of which are peroxides. Oxidation can also remove the coloration on the surface of the teeth and make the teeth whiter.

However, this whitening method is only effective on stains that are attached to the surface of the teeth, and it takes a while for it to work.

After all, the drug concentration in toothpaste is very low, and the brushing time is only three or five minutes. The contact time between teeth and bleaching ingredients is very limited, and the whitening effect is also limited.

Note: For deep internal staining caused by the disease of the teeth itself, whitening toothpaste is basically ineffective.
