It is not recommended to chew ice as it can cause damage to your teeth and potentially lead to dental problems.
Ice is a hard, rigid substance that can cause your teeth to chip, crack or fracture when bitten into. Chewing on ice can also cause damage to dental restorations, such as fillings, crowns or bridges. In addition, the cold temperature of the ice can cause sensitivity or pain in the teeth and gums, especially if you already have underlying dental problems.
Chewing ice can also be a sign of an underlying health issue, such as iron deficiency anemia, which can cause a craving for ice (known as pica).
If you feel the need to chew on something, consider opting for healthier alternatives such as sugar-free gum or crunchy vegetables like carrots or celery. If you experience any pain, sensitivity or damage to your teeth, make sure to schedule an appointment with your dentist to address the issue.
