That doesn't mean you can't break it.
Our office recommends to avoid eating "hard foods" such as popcorn. Don't crack nut shells with your teeth or chew on ice. Opening packages with your teeth can also damage the enamel.
It's not just the sugar - it's also the acid
Sugar and acids are your teeth's worst enemies. What are we talking about? Soft drinks, energy drinks, fruit juices, and candy.
Because of the acid content, Mountain Dew seems to be the worst of the worst. There is even a name for the damage it does and it is called "Dew Mouth."
These erode the tooth enamel, making it highly susceptible to decay. Parents, watch your kid's consumption of these because young children's enamle hasn't developed fully. This makes these drinks even more damaging for kids.
As well as eliminating the above (or at least reducing their consumption), it is recommended to always brush and floss after every meal. If you can't, use a sugar-free xylitol chewing gum after a meal. Also rinse your mouth with a high quality dental mouthwash.
