Heya there,

Someone just warned me that drinking Pepsi would end up giving my teeth a healthy brown shine because of the chemical colors and whatnot, to which I answered that thanks, but I brush my teeth every day. This topic isn't covered in the cokelore section of the site, I'm just wondering if there is any way to debunk this in a more scientific way?

Thanks!

Well, you could figure out what the coloring agent is (caramel color is descriptive but not very helpful chemically speaking). Once you know that, you can figure out whether it is a dye agent. Then you can probably look up on the 'net whether it's a colorfast dye or not.

Tea does stain the teeth. But then, you can use tea as a dye all by itself (tannic acid, ya know).

I've never heard of using caramel coloring as a dye, and since it washes out of fabrics without staining, I'd say there's a good chance that it is not colorfast.

It's more likly that the acid in soda will etch your teeth and make them more susceptable to any kind of stain.

"More likely" is a phrase indicating comparison--what are you comparing the acid etching to?

If the coloring agent is not a dye, it won't stain whether the surface is made susceptible to staining or not.

I am actually trying to get one of my friends to wrangle some teeth from a dentist buddy of hers so I can test it out. I also plan to re-test the disolving teeth myth since he apparently swears they do it all the time. Let me know if you want me to keep you posted on what happens.

My daughter did this as a science project about seven years ago. She used six of her baby teeth and soaked them in: Coke, Pepsi, lemon juice, orange juice, soda water, and tap water (as a control). She left them in the liquids (changing the liquid everyday) for five weeks. She took the teeth out every week and took pictures.

The results: none of the teeth should any appreciable signs of disolving, though the Coke and Pepsi teeth were noticeably brown.

She got an "A" on the project. [Smile]

I did that one as well as a science project in middle school. I didn't get any noticable decay of the teeth, either. It was then that I started to hear about these things called "urban legends." And the rest, as they say, is history.

Thank god for your tests! About 5 years ago I stopped drinking coffee and switched to a soda induced fix of caffeine when needed. I've often heard of the teeth rot legend and have been kinda worried about it but never stopped drinking the fizzy concoction.

Even though tea stains, the tannins are different from the tannic acid found in leather. Tea tannins are similar to the tannins found in grape skins.

Sodas are worse for you than tea or coffee, especially those made with high fructose corn syrup like Pepsi. I do enjoy a soda, but no more than 2 8oz servings a day. Instead I drink water, and get my caffeine boost from morning coffee and tea during the day.

In fact, the Mythbusters did this one while testing cola myths (such as cola as a cleaning agent for car bumpers and toilets).

The best way to prevent this from happening, IMO, would be to either drink something else or brush your teeth afterwards. For those occasions when you can't brush your teeth, I would imagine drinking some water (or possibly chewing sugar free gum, though I only know what the commercials tell me) would help a bit.

if drinking pepsi or coke made one's teeth turn brown, wouldn't a pretty significant portion of america be sporting brown chompers by now?

If you kept swilling coke around you mouth all day without swallowing yes it would stain, for the amount of time that the drink stays in the mouth the effect is negligable as any other colourant in food.

My dentist told me that chewing a piece of sugar free gum for 15-30 minutes after eating is good when you can't brush your teeth. Brushing is better, but the chewing gum causes a steady flow of saliva that washes out your mouth.

Unfortunately, he's also told me not to chew gum at all since I have problems with the TMJ from grinding my teeth when stressed.

My dentist told me just to drink coke through a straw.

When I was in school one of the girls did the desolving teeth science project, only she also used rootbeer. That one did actually disolve.

She got an 'A,' too. [Smile]

Just was thinking the other day:

Many years ago one of my older cousins told us kids that dentists tell their child patients not to drink Coke, but that it's okay to drink Pepsi because Coke has some ingredient that's bad for teth that Pepsi doesn't.

Then again, this cousin wasn't all that knowledgeable.

Thanks.

Just an note. I was a dental technician for 10 years (crowns and bridges basicly metal and porcelain work), and I can say with some certainty dentists don't know what they are talking about half the time. They are trained in their trade (pulling and filling)but precious little else on general matters like knowing what chemical constitutes dye, rot, or otherwise effects teeth.
It's like your local car mechanic telling you about the chemical constitutes of the oil you are using in your car. It's all personal opinion and about as accurate as your average old wifes tales.
