Is Chewing Ice Really That Bad for Your Teeth? (The Truth From Your Dentist)

It is a common habit that many people do without even thinking about it. You finish a refreshing cold drink and immediately start crunching on the leftover ice cubes at the bottom of your glass. While this might seem like a harmless way to cool down or relieve stress, chewing ice is actually one of the most damaging habits for your smile.

If you find yourself frequently crunching on ice, you are not alone. However, as dentists, we often see the unfortunate aftermath of this habit. The combination of extreme cold and hard textures creates the perfect storm for dental emergencies.

Let us explore why chewing ice teeth damage is so common and what you can do to protect your smile.

Why Do We Crave Chewing Ice?

Before we discuss the damage, it helps to understand why so many people are drawn to chomping on ice. For some, it is simply a nervous habit or a way to stay cool on a hot summer day in Cincinnati or Mason. For others, it provides a soothing sensation.

According to the American Dental Association (ADA), the habit of chewing ice can sometimes be linked to underlying medical conditions like iron deficiency anemia (a condition known as pagophagia). If you have an intense, uncontrollable craving to chew ice, it is always a good idea to bring it up with your primary care doctor.

What Happens to Your Teeth When You Chew Ice?

Your tooth enamel is incredibly strong. In fact, it is the hardest substance in the human body. However, tooth enamel is a crystal, and ice is also a crystal. When you force two crystals against each other with the strength of your jaw muscles, one of them is going to break.

While the ice usually breaks first, your teeth are taking on a tremendous amount of stress in the process. Over time, this constant pressure causes microscopic fractures in your enamel.

"Think of a windshield crack. Once a chip sets in, it can spread and form a bigger crack. This can happen to teeth with or without fillings in them." - University of Utah School of Dentistry

1. Cracked and Chipped Teeth

The most immediate risk of chewing ice is a broken tooth. A sudden bite on a hard piece of ice can easily cause a chip or a deep crack. If you experience pain when biting down after crunching on ice, you might be feeling the symptoms of a cracked tooth.

If a fracture occurs, you will likely need chipped tooth repair to restore the structure and appearance of your smile.

2. Damaged Dental Work

Your natural enamel is not the only thing at risk. The pressure and cold temperatures can easily damage your existing dental fillings, crowns, and veneers. The extreme cold causes materials to contract and expand slightly, weakening the bond between the restoration and your natural tooth.

3. Increased Tooth Sensitivity

As the protective layer of enamel wears down or develops micro-cracks, the sensitive inner layer of the tooth (dentin) becomes exposed. This can lead to sharp dental pain from hot or cold foods and beverages.

How to Break the Ice-Chewing Habit

Breaking a habit is never easy, but protecting your oral health is worth the effort. Here are a few dentist-approved strategies to help you stop crunching on ice:

• Skip the ice altogether: Request drinks without ice when you eat out, and keep your beverages chilled in the refrigerator at home.
• Use a straw: Drinking through a paper or reusable straw bypasses the ice entirely, removing the temptation to scoop a cube into your mouth.
• Switch to crushed ice: If you absolutely must have ice, try soft, crushed ice or shaved ice. It is much less damaging than solid cubes, though it should still be consumed carefully.
• Chew something else: Sugarless gum carries the ADA Seal of Acceptance and is a much safer alternative that also stimulates saliva production to protect your teeth.
• Let it melt: If an ice cube makes its way into your mouth, suck on it like a hard candy and let it melt instead of biting down.
