Why this habit can harm your teeth!
Many people chew ice without giving it a second thought. It can feel refreshing, especially on a hot day or after finishing a cold drink. But while it may seem harmless, chewing ice is one of the most damaging habits for your teeth — and it’s more common than you might think.
As dental professionals, we often see the long-term effects of this habit. Here’s what you should know about the risks and how to protect your smile.
1. Chewing Ice can Crack or Break Teeth
Ice is extremely hard. When you bite down, especially on large or solid cubes, the intense pressure can cause:
- Hairline cracks in the enamel
- Chipped edges
- Broken teeth that may require crowns, root canals, or even extraction
Even strong, healthy teeth aren’t built to withstand that kind of force repeatedly
2. It Damages Dental Work
If you have restorations like fillings, crowns, veneers, or bonding, chewing ice can quickly compromise them. Ice can loosen or crack dental work, leading to:
- Increased sensitivity
- Recurrent decay
- Costly repairs or replacements
3. It Leads to Tooth Sensitivity
Ice creates sudden temperature changes in the mouth. Over time, this can:
- Irritate the nerve inside the tooth
- Expose sensitive dentin
- Causes sharp pain when eating or drinking hot or cold items
If you’ve noticed sensitivity after chewing ice, it’s not a coincidence.
4. It can be a Sign of an Underlying Condition
Did you know that craving or chewing ice may be linked to iron-deficiency anemia or other nutritional deficiencies?
This condition, known as pagophagia, is recognized by medical professionals as a common symptom of anemia.
If you or your child constantly craves ice, talk with a healthcare provider.
5. It Wears Down Enamel
Enamel is the protective outer layer of your teeth — and once it’s gone, it does not grow back. Chewing ice can:
- Erode enamel
- Flatten chewing surfaces
- Create tiny fractures that worsen over time
This can make the teeth more vulnerable to cavities, staining, and sensitivity.
Safer Alternatives
If you enjoy the crunch or need help breaking the habit, try these safer options:
- Crushed ice (still not ideal, but softer than cubes)
- Cold water for refreshment
- Sugar-free gum to satisfy the chewing urge
- Chilled fruits like grapes
- Soft ice (nugget/pellet ice) — still safer, but moderation is key
