When Melbourne hits 35°C and you’re desperate to cool down, crunching on ice can feel incredibly satisfying. That instant chill, that crunch – it seems harmless enough.

But from a dental perspective, we see a different story.

Why Chewing Ice Is Bad for Your Teeth

Your teeth are strong, but they weren’t designed to crush frozen blocks of water. Ice is hard, and biting down on it places intense pressure on your enamel， which is the protective outer layer of your teeth.

Each time you chew ice, tiny microfractures can form in the enamel. You won’t notice them at first, but over time they can lead to chipped teeth, cracked fillings, loose crowns, or even sudden dental emergencies, often right in the middle of summer holidays.

There’s also the issue of temperature shock. Going from hot summer air to freezing ice causes your teeth to rapidly expand and contract. This weakens enamel further and increases the risk of damage.

Ice Chewing and Tooth Sensitivity

If you’ve ever felt a sharp pain when something cold touches your teeth, that’s a sign your enamel may be wearing down. Chewing ice accelerates this process, exposing the dentin underneath, the more sensitive inner layer of the tooth.

Ongoing tooth sensitivity isn’t something to ignore. A dental check can identify early damage and help prevent it from getting worse.

Tooth-Friendly Ways to Stay Cool

You don’t have to give up cold refreshment:

• Drink cold water without chewing the ice (a straw can help if you’re tempted).

• Try frozen fruit like grapes or watermelon for a cold, crunchy alternative.

• Let ice blocks melt in your mouth instead of biting into them.

• Chew sugar-free gum if you’re craving something to chew.

When to See a Dentist

If you regularly chew ice and notice any of the following, it’s time to book a check-up:

• Chipped teeth or rough edges

• Sensitivity that lingers after cold drinks

• Pain when biting

• A filling or crown that feels loose

With six locations across Melbourne, there’s always an MC Dental clinic near you to help, whether it’s a routine check-up or treatment for tooth damage.

One extra tip: if you find yourself craving ice constantly, it may be worth speaking to your GP. A condition called pagophagia (ice craving) can sometimes be linked to iron deficiency.

The Bottom Line

Melbourne summers are hot, and ice is tempting, but your teeth aren’t meant to be ice crushers. A few seconds of cooling relief isn’t worth long-term tooth damage or unexpected dental bills.

If you’re experiencing tooth sensitivity or think ice chewing may have caused damage, book an appointment at any MC Dental clinic. We’ll help keep your smile healthy all summer, and beyond.
