Study: Sugar-Free Soda and Snacks May Be Bad For Your Teeth

You will do your teeth a favor if you just stay away from any kind of soda drinks in general

No good deed goes unpunished. You may be decreasing the chance of becoming obese by switching to diet soda, which may not even be the case according to a recent study, but you may be damaging your teeth, according to another research.

Diet sodas often cause about the same amount of dental erosion as regular ones. Researchers at the University of Michigan compared the eroding effects of both kinds of drink and found almost no difference. After 14 days of exposure to regular coke, 2.8 mg/cm² of tooth enamel had dissolved, and diet coke dissolved a little over 3 mg/cm².

The citric and phosphoric acids in sugar-free drinks harm the tooth enamel. So next time you decide to buy a "diet" product, check the label for those. If they are used, your teeth are attacked by acid and their protection is getting weaker by the sip.

Snacks that claim have no sugar actually have these two ingredients, leaving your teeth prone to erosion.

Tooth decay is caused by bacteria in the mouth using sugar from foods and drinks to produce acids that dissolve and damage the teeth. But sugar-free drinks like Diet Coke can soften enamel by 30 to 50 percent. Experts studies 23 drinks, among them soda and energy boosters. It turns out that the regular and sugar-free drinks with acidic additives and low pH levels damaged the enamel just about the same.  

Two types of sugar alcohols – Xylitol and Sorbitol – are used in sugar-free foods, and they are harmful to tooth enamel. The two have a third of the calories that sugar does which is why they are used in diet soda drinks.

If you can’t lose the diet soda or stay away from the sugar-free candy because you like the taste so much, at least drink water right after to neutralize the acid.
