No matter the cause, it’s a habit worth breaking. Chewing ice is bad for your oral health, and if you’re unlucky, it may eventually cost you or your parents an expensive trip to the dentist or orthodontist.
If you break or fracture a tooth by chewing ice, you might get a cavity – a hole – in that tooth. That’s because acids produced by bacteria can penetrate the softer layer of the tooth, the dentin, much more easily and cause tooth decay.
If you already have fillings, crowns or veneers, or if you wear braces, use a retainer or have expanders, chewing ice makes you particularly vulnerable to tooth damage.
Depending on the severity of the problem, the repair may require anything from a simple filling to a root canal – a more serious procedure requiring anesthesia.
How to stop
There are several ways to kick this habit.
Melt cubes in your mouth: Instead of crunching ice cubes, try holding them in your mouth and letting them melt. The satisfying cool sensation and refreshment will last longer. And it won’t damage your teeth or gums.
Stop consuming ice: You can also skip the ice altogether. If it’s not in your glass, there’s no temptation. In addition to preventing damage to your teeth, you may also avoid the bacteria that can linger in icemakers.
Consider softer alternatives: Replacing regular cubes with softer types of ice, such as shaved ice, may help. Try to limit or avoid flavored soft ices, however, because they have lots of sugar, which is bad for your teeth.
Chomp on something healthier: Eating raw carrots, sliced apples or other crisp fruits and vegetables could help. Those foods can satisfy the craving to crunch, while stimulating the flow of saliva, which protects your mouth. The fibrous material may also help keep your teeth clean.
