You may be masking something serious
Eating ice may seem innocuous, but if it becomes a compulsive habit you could be doing serious damage to yourself. (Here are 10 other bad habits you should quit). In fact, chewing ice compulsively, called pagophagia, is a variant of pica—an eating disorder in which one craves non-food items (think hair, glue, dirt, and worse) can be a sign of a host of other very serious physical, mental and emotional ailments, all of which can have long-term consequences for your well-being.
You’re cracking tooth enamel
“Chewing ice is a habit that a lot of people have and are completely unaware of its harmful effects,” says Gregg Lituchy, DDS, a New York-based cosmetic dentist at Lowenberg, Lituchy & Kantor. “It will create wear and tear on enamel resulting in microfractures, which can potentially cause the tooth to break. This could even be as severe as needing root canal therapy.”
