Icy Truth: 10 health risks of chewing ice

Damages tooth enamel Chewing ice can wear down your tooth enamel, the protective outer layer, making your teeth more sensitive and vulnerable to cavities, staining and temperature-related discomfort.

Cracks and chips teeth The hardness of ice can cause cracks or even break your teeth, especially if they’re already weakened by fillings or previous dental work. These injuries often require expensive repairs.

Irritates gums Crunching on sharp ice pieces can injure or irritate your gums, causing soreness or bleeding. Repeated trauma can even lead to gum recession or sensitivity issues over time.

Damages fillings and crowns Dental work like fillings, crowns and veneers aren’t designed for hard pressure. Ice chewing can dislodge or break them, leading to unplanned visits to the dentist.

Jaw strain and pain Constant chewing of hard substances like ice can strain your temporomandibular joint (TMJ), potentially leading to jaw pain, headaches or clicking when you open and close your mouth.

Tooth sensitivity Frequent ice chewing can erode enamel and expose dentin, resulting in increased sensitivity to hot, cold or sweet foods. This discomfort can significantly affect your eating habits and comfort.

Possible sign of iron deficiency Craving and chewing ice, a condition called pagophagia, can be a sign of iron-deficiency anaemia. If you find it hard to stop, it’s worth consulting a healthcare provider.

Triggers headaches For some people, chewing ice can lead to brain freeze or trigger headaches, especially if you’re sensitive to cold temperatures in the mouth and sinuses.

Socially distracting habit The sound of chewing ice can be disruptive in social or professional settings. It’s often considered a nervous or unconscious habit that can distract others around you.

Risk of choking Although rare, chewing on larger ice chunks increases the risk of choking if a piece breaks off and slips into your throat unexpectedly, especially when talking or laughing.
