Our diet plays a crucial role in maintaining our overall health, including the health of our teeth and gums. Certain foods can lead to tooth enamel erosion, causing dental problems such as cavities, decay, and sensitivity.
Here are some of the worst foods you should avoid for your teeth:
• Diet soda
• Candy
• Powdered starches
• Liquid sugar containing high-fructose corn syrup
• Soda with phosphoric acid
• Gummy bears and caramels
But out of all these, the worst food for your teeth is not sugar but citric acid!
Citric acid is a common ingredient in many processed foods and drinks, including fruit juices, diet sodas, and even some toothpaste. Despite being found naturally in fruits like lemons and limes, the citric acid used in processed products is often synthetically made.
Citric acid is a powerful calcium chelator, which means it binds with calcium and pulls it out of teeth. This can lead to erosion and demineralization of teeth, causing them to weaken and become more susceptible to cavities.
The pH of citric acid is also a contributing factor. While the ideal pH in the mouth is slightly above 7 (neutral or slightly alkaline), citric acid has a lower pH of around 3 to 6, making it even more damaging.
The worst type of citric acid for teeth is trisodium citrate, also known as sodium citrate. It's commonly found in many processed products and is a major contributor to tooth erosion.
So what can you do to protect your teeth from the harmful effects of citric acid?
• Rinse your mouth with water after consuming anything
• Check labels carefully and opt for products without synthetic citric acid
• Use toothpaste that does not contain citric acid, or make your own at home using natural ingredients

0:00.0 | You know the worst food for your teeth is not sugar. |
0:03.4 | Now it is true that sugar does increase bacteria that make more |
0:07.4 | acids that can erode your teeth, but there's a much worse type of acid that will severely erode your teeth and it doesn't have anything to do with sugar. |
0:18.2 | Of course, if we talk about fruit juice, like apple juice or orange juice is five times worse than soda for your teeth. |
0:27.6 | Yeah, interesting. And I'm going to explain why that is in just a minute. Diet soda compared to regular soda. Can you take a guess |
0:35.9 | what's worse for your teeth? Believe it or not, Diet soda might be worse and I'm going |
0:41.3 | to explain why that is as well. Number two, candy, the stuff that you |
0:45.4 | suck on like a lollipop for example, you're constantly exposing your teeth to a lot of |
0:50.6 | sugar and that could definitely create microbes that make more acid. |
0:53.4 | Number three, powdered starches. Starches can act just like a sugar and feed these microbes |
1:01.4 | and create the acids. |
1:02.8 | And that would be like modified foodstarch or modified cornstarch or multodextrin, |
1:06.8 | which is in pretty much most junk foods. |
1:10.0 | And then we just get liquid sugar, as in high fruitous corn syrup drinks, right? |
1:15.0 | And I'm talking about the ones that you have added sugar. |
1:18.0 | In this case, you're not chewing, you're just bathing the teeth in just pure sugar. And just if we differentiate |
1:25.8 | between natural sugars like if you eat fruit versus drink the juice from |
1:30.8 | fruit, especially if it's pasteurized, there's a big difference. |
1:34.0 | And then number five, we get into actual sodas with phosphoric acid. |
1:39.0 | And believe it or not, phosphoric acid is not the worst acid for your teeth. There's another one that's |
1:45.1 | actually way more dangerous, but phosphoric acid is not good. It's going to leach the |
1:50.1 | calcium out of your teeth. So here you have a soda with not just liquid candy |
