Not true, any carbonated beverage is acidic and not so great for your teeth. As with most things moderation is the way to go, but still, carbonated beverages are decidedly not good for you.
- corysama 9y agoAt what point is the only thing left to be decidedly good for you plain water? I wonder what is the pH of glass of carbonated water with a squeeze of lime?
- scottie_m 9y agoThat’s a good question, and if you’ll permit me, I’ll give the answer in two parts. The acidity of seltzer is roughly the acidity of orange juice, so a squirt of lime in your water is just nowhere close. It is also true that most of what we should be drinking is water. I realize that’s not the first choice for people raised on juice, milk, and soda, but it’s certainly the most healthy. Remember that I mentioned moderation though? A glass or two of OJ, lemonade, tea, coffee, or seltzer a day isn’t going to materially impact your health assuming you’re not diabetic, and practice good oral hygiene. There are also many worse things for your teeth than seltzer, such as potato chips, and poor oral hygiene. If most of what you’re drinking is water, don’t sweat the glass or two of something other than water. Unfortunately too many poeple drink very little unadulterated water, and it does impact their health. Moderation is the key.
- davidwihl 9y agoWhy are potato chips bad for your teeth? They are mostly oil and salt.
- jdminhbg 9y agoThey’re mostly starch, which the enzymes in your mouth convert to sugar.
- blawson 9y agoThey get stuck in between, and in your gums, in a way that (obviously) liquids don’t.
- rleigh 9y agoIt's not what they are made of, it's the effect they have. Bits get stuck between your teeth and gums, and this encourages bacteria to grow and establish biofilms, which once established can start causing tooth decay. Long term, they can cause a lot of damage.
- minhaz23 9y agoCan you neutralize the harm by drinking through a straw?
- brandon272 9y agoUnfortunately, not even plain water is uncontroversial.
- B1FF_PSUVM 9y agoHe's not wrong, matter of quantity: https://en.wikipedia.org/wiki/Water_intoxication https://en.wikipedia.org/wiki/Water_intoxication ('Notable cases' include recorded death.)
- StavrosK 9y agoYeah but that's way way past the point where it's very uncomfortable to drink more water. It's not something that can happen to you without warning (or while you're enjoying the process).
- candiodari 9y agoWell obviously any lifeform has water problems. Like any other lifeform, our life depends on remaining within osmotic balance with whatever we drink and eat. That said, the amount of ways your body adapts to osmotic balance problems is in the dozens, so poisoning your body with water, while possible, is hard to the tune of it requires something like drinking 20 liters of water in less than an hour. I mean, it seems to be possible but I cannot imagine succeeding at that even if I'm trying. That's 2 full buckets (and that's just LD50, as in, if you're >70kg it's more than that). There is an exception: purified water. You cannot drink mineral-poor* or distillated water safely in even small quantities. Why not ? Because that will locally, suddenly and very strongly disrupt the osmotic balance in what you bring it into contact with. It probably not kill you (not without repeated application), but it may cause serious issues in your mouth, throat and stomach. It should also not be used to make coffee or tea and drunk, that merely lessens the effect it doesn't stop it. * mineral-poor water is something used in chemical and medical laboratories
- Laforet 9y agoCarbonated water typically have a pH around 4, adding lime juice may reduce it slightly further, but not by a huge margin. Acidity of most beverages on its own is usually not problematic as saliva (buffered at 6.5 pH) rapidly restores normal pH. It does become an issue if the salivary glands are damaged (as in the case of meth users) or stomach acid comes into contact with teeth.(severe acid reflux or bulimia) However these cannot be considered normal. The number one cause of dental cavities is always sugar.
- wbkang 9y agoPretty sure your teeth can rebuild the top layers fine. I think it's really far from decidedly bad for you? By that token plain water is also bad if not taken in moderation because it can kill you.
- scottie_m 9y agoSo, tooth enamel can be removed mechanically (overbrushing, injury...), but more typically it’s demineralized and breaks down. In the first case you’re shit out of luck, you’re unable to make new enamel. The good news is that deminerlized enamel can be restored if it’s not too far gone, which is what fluoride is trying to do in your toothpaste. So no, there is a rebuilding process, but the kind of damage done by acidic substances (including the excretions of bacteria) can sometimes be reversed to some extent. The trend is usually erosion however, and moderate intake of something like seltzer or soda is at least an order of magnitude less than straight water. In addition, while water toxicity is a thing, you’d have to overcome a pretty strong urge to vomit. Short of that, water is doing you no harm, and will never contribute to the erosion of your dental enamel.
- fouc 9y agoThere's a new fluoride replacement called novamine that is apparently significantly better at re-mineralizing teeth.
- Laforet 9y agoNovamin is technically a desensitising agent by blocking tubules on exposed dentin (boney tissue below enamel). There is some evidence suggesting it may aid remineralisation in combination with fluoride, however it is far from conclusive. A number of toothpaste brands in Japan claims to remineralise teeth with a hydroxyapatite based formula but the results are yet to be confirmed. Dentists have been using zinc oxide gels and other material to seal exposed dentin but the results are mixed and eventually the filling will fail. Once cavities reach a certain size not much can be done about it.
- cowmix 9y agoI've been conducting an informal science experiment with my family for the past 20 years. My wife, my older son (19), my younger son (15) and I have ONLY drink carbonated water. Period. Every drink, every meal. My kids have no cavities / perfect teeth. My wife and I, by that age range, had tons of cavities.
- koolba 9y agoDid you drink well or city water as a child? The fluoride in the water could be a factor as well.
- candiodari 9y agoKeep in mind that "acidic" should be kept in perspective. Carbonated beverages: More acidic than: water milk tea ice tea beer About that same as: coffee (coffee with milk, however, is essentially not acidic) wine (depends a bit on the kind of wine, sweet wine is less acidic) orange juice (from sweet oranges, the sour ones are usually less acidic) Less acidic than: lemon juice (coke is a LOT less acidic than lemon juice)* grape juice (esp. when adding lemon juice for more sweetener) lime juice things like "lemon ice tea" (and of course actual tea with lemon in it. It depends on how much lemon. If you add enough lemon to allow for much additional sweetness, it will be a lot more acidic than carbonated beverages) With fruit things can vary. Apparently the rule is, the sweeter, the more acidic (the opposite of what your tastebuds will tell you, although it's really more a case of if you taste sweetness you ignore sourness. Sweet taste doesn't necessarily mean something is acidic, obviously, but (from a certain level) it does mean you won't notice at all whether something is acidic or not, or how much). If you're worried about this, even a small sip of milk will eliminate any acidity in your mouth in seconds (milliseconds actually). * I've heard of medical cases where people managed to dissolve their stomach lining by drinking pure lemon juice (about 1.5 liter), and died due to the stomach juices coming into the abdominal cavity. Yes, that's right, your stomach lining, specifically designed to be able to handle strong acidity, cannot deal with lemon juice.
