Chewing ice might seem harmless and refreshing, especially on a scorching hot day or when you’re enjoying a cold beverage. However, this seemingly innocent habit can have significant consequences for your oral health and overall well-being. Ice is a solid form of water, and while it may seem harmless to crunch on, it can pose dangers to your teeth and mouth. In this comprehensive blog post, we will explore the dangers of chewing ice, understand the potential risks to your dental health, delve into the reasons why people chew ice, and discuss practical tips to break this habit for a healthier smile.

Understanding the Habit of Chewing Ice:

The habit of chewing ice, known as pagophagia, can be more common than you think. Some people find pleasure in the crunching sensation and enjoy the coolness it brings to their mouth. However, this habit is not as innocuous as it may seem, and indulging in it regularly can lead to serious consequences for your teeth and overall oral health.

The Dangers of Chewing Ice:

Enamel Erosion: 

Chewing on hard and cold ice can cause microscopic cracks and fractures in your tooth enamel, the protective outer layer of your teeth. Over time, these cracks can weaken the enamel and lead to enamel erosion, making your teeth more susceptible to cavities and tooth sensitivity.

Tooth Fractures: 

The extreme hardness of ice cubes can exert immense pressure on your teeth, leading to chipped, cracked, or fractured teeth. This can result in significant pain and discomfort, requiring immediate dental attention.

Dental Restorations Damage: 

If you have dental restorations, such as fillings, crowns, or veneers, chewing ice can cause damage to these dental fixtures. Ice’s hardness can chip or break dental restorations, leading to the need for costly repairs or replacements.

Jaw Pain and Discomfort: 

Chewing on ice involves repeated and forceful biting motions, which can strain your jaw muscles and temporomandibular joint (TMJ). This strain can lead to jaw pain, headaches, and discomfort.

Gum Injury: 

Chewing ice can also damage your gum tissues, leading to irritation and potential injuries. The sharp edges of ice cubes can cause cuts or abrasions in your gums, making them more susceptible to infections.

Cold Sensitivity: 

Chewing on ice can expose your teeth to extreme cold temperatures, causing sensitivity in your teeth. Cold sensitivity can make eating and drinking uncomfortable and can impact your overall quality of life.

Reasons Why People Chew Ice:

Several reasons might contribute to why people develop the habit of chewing ice:

Pica Disorder: 

Some individuals with pica disorder, a condition characterized by cravings for non-nutritive substances, might find themselves craving ice. Pica can be linked to certain nutrient deficiencies or underlying health conditions.

Iron Deficiency Anemia: 

In some cases, craving ice (pagophagia) could be a symptom of iron deficiency anemia. This condition can lead to a strong desire to chew ice or other non-food substances.

Oral Habits: 

Some individuals develop the habit of chewing ice as an oral habit or a way to alleviate boredom or stress.

Breaking the Habit of Chewing Ice:

Recognizing the dangers of chewing ice is the first step towards breaking this potentially harmful habit. Here are some practical tips to help you stop chewing ice:

Address Underlying Health Issues: 

If you suspect that pagophagia might be related to an underlying health condition, such as iron deficiency anemia, consult with your healthcare provider for appropriate evaluation and treatment.

Opt for Crushed Ice: 

If you enjoy the sensation of crunching ice, consider switching to crushed ice, which is softer and less damaging to your teeth.

Use Ice in Beverages, Not for Chewing: 

Instead of chewing ice cubes, use them in your beverages to keep them cold. Allow the ice to melt naturally and avoid the temptation to chew on it.

Drink Cold Water: 

If you crave the coolness in your mouth, opt for cold water instead of chewing ice. Sip on cold water throughout the day to stay hydrated and refreshed.

Chew Sugar-Free Gum: 

If you have an oral habit of chewing, switch to sugar-free gum. Chewing gum can help satisfy the urge to chew and stimulate saliva flow, which is beneficial for oral health.

Practice Stress Management: 

If you find yourself chewing ice as a response to stress or anxiety, explore alternative stress-management techniques, such as deep breathing exercises, meditation, or engaging in relaxing activities.

Use a Straw: 

If you enjoy the cold sensation of ice in beverages, use a straw to drink cold drinks, minimizing the contact of ice with your teeth.


Chewing ice might seem like a harmless and refreshing habit, but it can have significant consequences for your oral health. The hardness and cold temperature of ice cubes can lead to enamel erosion, tooth fractures, and gum injury. Furthermore, pagophagia might be linked to underlying health issues or oral habits that require attention and management. By recognizing the dangers of chewing ice and following practical tips to break this habit, you can protect your teeth and oral health, ensuring a beautiful and healthy smile for years to come. Remember, taking care of your teeth is an investment in your overall well-being, and breaking the habit of chewing ice is an essential step towards maintaining excellent oral health.
