Whitening your teeth or using whitening toothpaste which one is healthier ?
Whitening works by temporarily dehydrating your teeth. Enamel is actually the hardest material in your body and believe it or not, it is stronger than bone! Enamel is made up of about 2% water content (the rest is calcium and other strong minerals). When we whiten, we temporarily remove a bit of water content and that water contents comes back about an hour after whitening. What also happens is all those stains that are trapped in enamel come out with that water. This is pretty much how whitening works. No enamel is removed. No calcium or other strong minerals are removed during the whitening process.
On the other hand, when we brush our teeth with whitening toothpaste, we are actually scrubbing away the enamel due to the abrasive ingredients found in all whitening toothpastes. A study
of popular toothpaste brands such as Colgate, Sensodyne, Coles, Macleans, Woolworth and White Glo, indicate that there isn’t much difference in the core formulas that go into these products. Some toothpastes, like Colgate’s Advanced Whitening product, and Woolworth’s Home-brand Freshmint Toothpaste use hydrated silica for their abrasive agent, while White Glo Extra Strength Coffee and Tea Drinkers Formula use a calcium carbonate-based abrasive. They are all much of a muchness. You know the rough ‘sand paper’ nail filer you use to file down your nails? That’s what you’re using on your teeth. Whitening toothpastes will reduce the strength and hardness of the enamel in your teeth. Not to mention, they can lead to extreme sensitivity in teeth.
You forgot to ask me one other important question – do whitening toothpastes work?
Unfortunately, we don’t have any teeth whitening toothpastes to recommend, because teeth whitening toothpaste does not work enough to call it a teeth whitening solution! They certainly do a good job at marketing but that’s about it. You’ll find it lining the shelves of supermarkets and chemists in special looking packaging that include wild claims of whiter and brighter teeth, however do a simple search online (type in “does whitening toothpaste work?”) and you’ll hear a different story. If you’re looking for whiter teeth on a budget, consider using an at-home whitening kit or trying dental chair cosmetic teeth whitening.
Back to the original question – Whitening toothpastes work very differently to whitening gels as they work by removing the outer surface of enamel, while whitening gels work by dehydration. What’s the verdict over the debate between whitening toothpastes vs whitening gels? Whitening gels win by a long shot!
