Even Without Sugar, Diet Soda Is Bad for Teeth Too

Just because soda is sugar-free, that doesn’t mean that it’s not bad for your teeth. A new study has been released that states that sugar-free drinks, like diet soda, can cause dental erosion. The authors argue that there should be labeling on these products that tell the consumers this so they can make more informed decisions about their dental and overall health.

It’s widely understood that sugar is bad for teeth. So it would be logical to believe that a diet sugar-free can of soda is the better choice for your pearly whites. The problem is that these diet sodas are often highly acidic. And the acid they contain can soften the surface of your teeth and erode the enamel. Once enamel is gone, it does not grow back.

The report states that “There was no significant difference between the erosive potential of sugared and non-sugared soft drinks.” So, if you switched to diet soda for the sake of your teeth, you may need to consider another alternative.
According to the report, the ingredients that cause this erosion are phosphoric acid, sodium citrate, critic acid, magic acid, fumaric acid, tartrates, and tartaric acid.

Keep a look out for these ingredients the next time you grab your favorite drink. When you see them listed, picture them eroding your tooth enamel, and then put the drink back on the shelf.

What are the best drinks for your teeth? Water (especially if it’s fluoridated), milk and unsweetened tea. You should limit your added sugar consumption in your food and drinks to 50 grams per day to maintain a healthy diet.

Although your body can’t grow new enamel, you can strengthen the enamel you have through a process called remineralization. Products that contain fluoride and calcium can find the weak spots in your enamel, and strengthen those spots before the enamel is worn away. Yet another great reason to drink fluoridated water instead of sugary drinks.
