Chewing ice may seem harmless and refreshing, especially on a hot summer day. However, this seemingly innocent habit can have detrimental effects on your dental health. Many people are unaware of the potential dangers of chewing ice and continue to indulge in this habit without realizing the consequences. In this article, we will explore the dental don’ts of chewing ice and why it is important to break this habit for the sake of your oral health.

The Structure of Teeth

Before delving into the dental don’ts of chewing ice, it is essential to understand the structure of teeth and how they function. Teeth are composed of several layers:

  • Enamel: The outermost layer of the tooth, which is the hardest substance in the human body. Enamel protects the underlying layers of the tooth from damage.
  • Dentin: The layer beneath the enamel, which is less dense and more sensitive than enamel.
  • Pulp: The innermost layer of the tooth, which contains blood vessels, nerves, and connective tissue.

When you chew on ice, you subject your teeth to extreme pressure and temperature changes, which can lead to various dental problems.

The Risks of Chewing Ice

Chewing ice may seem harmless, but it can have serious consequences for your dental health. Here are some of the risks associated with this habit:

1. Tooth Fractures

Ice is a hard substance, and when you chew on it, you expose your teeth to the risk of fractures. The force exerted while biting down on ice can cause cracks or chips in the enamel, leading to weakened teeth. These fractures can be painful and may require dental intervention to repair.

2. Tooth Sensitivity

Chewing ice can also lead to tooth sensitivity. The extreme cold temperature of the ice can cause the enamel to contract, exposing the underlying dentin. Dentin contains tiny tubules that connect to the nerves of the tooth, making it more sensitive to hot and cold stimuli. Over time, this can result in discomfort or pain when consuming hot or cold foods and beverages.

3. Dental Fillings and Restorations

If you have dental fillings or restorations, chewing ice can pose an additional risk. The force exerted while biting down on ice can cause these fillings or restorations to crack or become dislodged. This can lead to further dental problems and may require additional dental work to repair or replace the damaged fillings or restorations.

4. Jaw Problems

Chewing on ice requires significant force, which can put strain on your jaw joints and muscles. Over time, this repetitive motion can lead to temporomandibular joint (TMJ) disorders, causing jaw pain, headaches, and difficulty in opening or closing your mouth properly.

5. Increased Risk of Cavities

Chewing ice can also increase your risk of developing cavities. While ice itself does not contain sugar, it can cause damage to the enamel, making it more susceptible to bacterial attack. Bacteria in the mouth feed on sugars and produce acids that erode the enamel, leading to tooth decay. Additionally, chewing ice can also cause microfractures in the enamel, providing a breeding ground for bacteria.

Breaking the Habit

Now that we understand the risks associated with chewing ice, it is important to break this habit for the sake of your dental health. Here are some tips to help you stop chewing ice:

  • Find alternatives: Instead of chewing ice, try chewing sugar-free gum or snacking on crunchy fruits and vegetables.
  • Drink cold beverages without ice: If you enjoy the cold sensation, opt for chilled beverages without ice to satisfy your craving.
  • Identify triggers: Pay attention to situations or emotions that trigger your ice-chewing habit and find healthier ways to cope with them.
  • Seek support: If you find it difficult to break the habit on your own, consider seeking support from friends, family, or a healthcare professional.
  • Practice good oral hygiene: Maintaining a consistent oral hygiene routine, including brushing twice a day, flossing, and regular dental check-ups, can help prevent dental problems and reinforce your commitment to breaking the ice-chewing habit.


Chewing ice may seem harmless, but it can have serious consequences for your dental health. The risks of tooth fractures, tooth sensitivity, damage to dental fillings, jaw problems, and an increased risk of cavities make it important to break this habit. By understanding the structure of teeth and the potential dangers of chewing ice, you can make informed decisions about your oral health. Remember to seek support if needed and practice good oral hygiene to maintain a healthy smile. Breaking the ice-chewing habit is a small step that can lead to significant improvements in your dental well-being.
