Love Chewing Ice? It Could Damage Your Teeth and Jaw

Key TakeawaysRegularly chewing ice can weaken tooth enamel, crack fillings and increase sensitivityThe habit may also cause jaw strain and has been linked to jaw painA strong craving for ice could be a sign of dehydration or anemia.MONDAY, Oct. 6, 2025 (HealthDay News) — Chewing on ice may seem harmless, perhaps even refreshing, but dental experts warn it can actually wreak havoc on your teeth. While the occasional crunch of an ice cube isn’t likely to do severe damage, making it a daily habit can lead to enamel damage, cracked fillings and even jaw pain over time.Ice is among the hardest things people regularly bite into and repeated pressure can chip or fracture the tooth’s protective outer layer. Once that layer, the enamel, is weakened, teeth become more sensitive to hot and cold foods and drinks and prone to further injury."Many people chew ice because it feels refreshing, but frequent cravings might indicate a deeper cause," Dr. Aikaterini Papathanasiou said in a news release. She’s a professor and chair of the Comprehensive Care Department at Tufts University School of Dental Medicine in Boston.Further, the habit can damage dental work oftentimes without immediate symptoms, and over time, people may experience sharp tooth sensitivity or notice tiny cracks that require more expensive repairs.Beyond the teeth, the repetitive stress from crushing ice can strain jaw muscles. Research shows that people who often chew ice are more likely to experience tenderness or pain in the temporomandibular joint, which connects the jaw to the skull.Experts say frequent cravings for ice may also point to deeper health issues. Some people chew ice because it helps relieve dry mouth or dehydration. But a constant urge to crunch ice (also known as pagophagia) can sometimes signal an iron deficiency or anemia.If quitting the habit feels impossible or if ice cravings happen daily, experts recommend talking with a doctor to check for underlying causes. In the meantime, choosing cold water or softer frozen items can satisfy cravings without doing damage to your smile.More informationThe Mayo Clinic has more on iron deficiency anemia.SOURCE: Tufts University, news release, Oct. 3, 2025.What This Means For YouChewing ice might seem harmless, but it can damage your teeth and jaw.
