Although it may seem harmless, the habit of chewing ice can have serious consequences for oral health. Many people do it for pleasure, to cool down, or even as a way to relieve stress, but this behaviour can significantly damage both teeth and gums.
The main risk lies in the wear of tooth enamel – the protective outer layer of the teeth. Ice, being extremely hard, can cause microfractures, and in some cases full fractures or cracks, particularly in those who already have fillings, cavities, or weakened teeth. Furthermore, repeated exposure to extreme cold can lead to tooth sensitivity, making it uncomfortable to consume hot or cold foods and drinks.
Another common issue is gum trauma. Chewing ice cubes can injure the gums, leading to inflammation and, in more severe cases, promoting infection. For individuals who wear orthodontic braces, dentures or dental veneers, the risk is even greater, as the impact from the ice may damage these devices and compromise the ongoing treatment.
In some cases, a compulsive craving to chew ice, known as pagophagia, may be linked to nutritional deficiencies, such as iron deficiency or anaemia. In these instances, it is essential to investigate the underlying cause with a healthcare professional.
Therefore, despite appearing to be a harmless habit, chewing ice is not recommended. To cool down or stay hydrated, it is best to opt for drinking cool water. In cases of pain, sensitivity, or dental fractures, you should consult a dentist for appropriate evaluation and treatment.
