The Harmful Effects of Chewing Ice

  • Feb 10
  • 4 min read

Chewing ice might seem like a harmless habit, especially on a hot day or when you want to keep your mouth busy. However, this seemingly innocent activity can lead to several health problems. Many people chew ice without realizing the potential damage it can cause to their teeth and overall oral health. This article explores the harmful effects of chewing ice, why some people crave it, and what you can do to break the habit.


Understanding the Harmful Effects of Chewing Ice


Chewing ice can cause significant damage to your teeth and gums. Ice is hard and brittle, and biting down on it can lead to cracks, chips, or even broken teeth. These dental injuries can be painful and expensive to fix. Additionally, chewing ice can wear down the enamel, the protective outer layer of your teeth, making them more sensitive to hot and cold foods and drinks.


Another concern is that chewing ice can irritate your gums. The sharp edges of ice cubes can cause small cuts or abrasions, leading to inflammation or infection if not properly cared for. Over time, this can contribute to gum disease, which affects not only your oral health but also your overall well-being.

Moreover, chewing ice can damage dental work such as fillings, crowns, and braces. The pressure from biting hard ice can loosen or break these restorations, requiring costly dental visits for repairs or replacements.


If you have sensitive teeth or dental issues, chewing ice can exacerbate the problem. It can cause sharp pain or discomfort, making it difficult to enjoy your meals or drinks.


What is wanting to chew ice a symptom of?


Craving ice, also known as pagophagia, can sometimes be a sign of an underlying health condition. One common cause is iron deficiency anemia. People with this condition often experience unusual cravings, including the desire to chew ice. This craving may be linked to the soothing effect of cold on inflamed or irritated tissues in the mouth.


Other possible causes include nutritional deficiencies, stress, or obsessive-compulsive disorder (OCD). If you find yourself frequently wanting to chew ice, it is important to consult a healthcare professional to rule out any medical issues.


Addressing the root cause of the craving can help reduce the habit and prevent the harmful effects associated with chewing ice.


The Dangers of Chewing Ice and How to Avoid Them


The dangers of chewing ice are not just limited to dental damage. Habitual ice chewing can also lead to jaw problems. The repetitive motion and force can strain the jaw muscles and joints, potentially causing temporomandibular joint (TMJ) disorders. Symptoms of TMJ disorders include jaw pain, headaches, and difficulty opening or closing the mouth.


To avoid these problems, consider the following tips:


  • Replace ice with healthier alternatives: Chew sugar-free gum or crunchy vegetables like carrots or celery to satisfy the need for oral stimulation.

  • Stay hydrated: Sometimes, people chew ice because they are thirsty. Drinking enough water can reduce the urge to chew ice.

  • Manage stress: Since stress can trigger habits like ice chewing, practicing relaxation techniques such as deep breathing or meditation may help.

  • Seek professional advice: If you suspect an underlying health issue, consult a doctor or dentist for proper diagnosis and treatment.

How Chewing Ice Affects Your Oral Health Over Time


Repeatedly chewing ice can have long-term consequences for your oral health. The constant pressure and impact can cause microfractures in your teeth, which may not be immediately noticeable but can worsen over time. These microfractures weaken the tooth structure and increase the risk of tooth decay and infection.


Additionally, the enamel erosion caused by chewing ice can lead to increased tooth sensitivity. This sensitivity can make eating and drinking uncomfortable, especially when consuming hot, cold, or sweet foods.


Gum irritation from ice chewing can also lead to receding gums, exposing the roots of your teeth. This exposure increases the risk of cavities and tooth loss.


Regular dental check-ups are essential to monitor any damage caused by chewing ice and to receive timely treatment.


Breaking the Habit: Practical Tips to Stop Chewing Ice


If you want to stop chewing ice, here are some practical steps you can take:


  1. Identify triggers: Notice when and why you chew ice. Is it boredom, stress, or thirst? Understanding your triggers can help you find alternatives.

  2. Keep your mouth busy: Chew sugar-free gum or munch on crunchy fruits and vegetables.

  3. Stay hydrated: Drink plenty of water throughout the day to reduce cravings.

  4. Use a straw: Drinking cold beverages through a straw can help you avoid chewing ice cubes.

  5. Replace ice cubes with crushed ice: Crushed ice is softer and less likely to cause damage.

  6. Seek support: Talk to your dentist or doctor if you find it difficult to stop. They can provide guidance and check for any underlying health issues.


By following these tips, you can protect your teeth and gums from the harmful effects of chewing ice.


Taking Care of Your Teeth After Chewing Ice


If you have a habit of chewing ice, it is important to take extra care of your teeth. Here are some recommendations:


  • Use a soft-bristled toothbrush to avoid further enamel wear.

  • Brush gently and floss daily to maintain healthy gums.

  • Use toothpaste for sensitive teeth to reduce discomfort.

  • Avoid very hot or cold foods and drinks if your teeth are sensitive.

  • Visit your dentist regularly for check-ups and professional cleanings.


If you notice any pain, cracks, or chips in your teeth, see your dentist promptly to prevent further damage.



Chewing ice might seem like a simple habit, but it can lead to serious dental and health problems. Understanding the risks and taking steps to stop can save you from pain and costly dental treatments. Remember, if you experience strong cravings for ice, it might be a sign of an underlying health issue that needs attention. Protect your smile by making healthier choices and seeking professional advice when needed.
