Sugar-free soda is no better than regular soda when it comes to dental decay, Bassiouny added. "Both of them have the same drastic effect if they are consumed in the same frequency, the same amount and the same duration," he said.
Antenucci said people need to keep in mind that they are drinking something that is highly acidic when they pick up a soda.
"Knowing that, you limit it and understand that you need to clean your mouth afterward," he said. "Even simple water will wash away the acidity. And everyone should brush twice a day, if not more often."
Should people give up drinking soda? "You'd be better off if you didn't drink the soda," Antenucci said, "but in my mind there's not a reason for that extreme."
