Chewing Ice, Nail Biting, and Other Habits That Hurt Your Teeth

From chewing ice cubes to biting your nails, everyday habits can seem harmless—until they start to harm your teeth. These actions may offer short-term comfort or convenience, but over time, they can cause serious damage. Understanding how these habits affect your oral health can help you protect your smile for years to come.

Chewing Ice: Cool, But Not Tooth-Friendly

Chewing ice may seem like a fun way to cool off, but it’s one of the top bad habits that can damage your teeth. Ice cubes are hard and can lead to chipping or cracking of your tooth enamel. Once enamel is damaged, your teeth are more vulnerable to tooth decay and tooth loss. Instead of crunching ice, try sipping cold drinks or switching to chilled water to stay cool without the risk.

Nail Biting: Stress Relief That Bites Back

Biting your nails is often a nervous habit, but it can cause serious harm to your teeth and gums. It puts pressure on your teeth in ways they’re not meant to handle, which can lead to misalignment and enamel wear. Nail biting can also introduce bacteria into your mouth, raising the risk of infections and even oral cancer over time. Some people find success breaking the habit by using bitter-tasting nail polishes or keeping their hands busy with a stress ball or fidget tool.

Using Your Teeth as Tools

Your teeth were made for eating, not for opening packages or tearing tags. Using your teeth as tools may be convenient at the moment, but it’s a shortcut that can lead to cracks, chips, or even broken teeth. Reach for scissors instead and give your teeth a break.

Grinding and Clenching: Silent Nightly Damage

A lot of people clench or grind their teeth at night without even knowing it. Over time, this habit can wear away enamel, cause jaw discomfort, and potentially loosen teeth. Wearing a custom-fitted mouth guard from your dentist is an effective way to shield your teeth while you sleep.

Not Brushing Properly

Even brushing your teeth can be damaging if you’re not doing it right. Using a hard-bristled brush or brushing too aggressively can erode enamel and irritate your gums. Use a soft-bristled toothbrush and brush with light, circular strokes to avoid harming your gums or enamel. Keeping up with brushing two times a day and flossing every day is key to maintaining good oral health.

Drinking Dark Beverages

Coffee, tea, and sodas may get you through the day, but they can stain teeth over time. Some of these drinks also contain acids that wear away enamel. Rinse your mouth with drinking water after having these beverages to reduce their effects, and drink through a straw when possible.

Is It a Cavity or Just Tooth Sensitivity?

Do you experience a sudden tingling sensation when consuming hot or cold beverages? You’re not the only one. Tooth discomfort is common. But how can you tell if it is just sensitivity or a more serious problem, like a cavity that needs a dentist?

Here’s what you should know when you experience that familiar twinge.

What Is Tooth Sensitivity?

Tooth sensitivity often arises when the enamel, which is the protective outer layer of your teeth, becomes worn. It may also occur when the gums recede, revealing the underlying dentin. This layer has tiny tubules that permit hot, cold, or sweet sensations to access the nerves within your tooth.

Common causes of tooth sensitivity include

  • Enamel erosion from acidic foods or drinks
  • Brushing too hard
  • Teeth grinding (bruxism)
  • Gum recession or early gum disease
  • Whitening products or harsh toothpaste

If your pain is sharp and brief, it may happen with certain triggers, like temperature or sugar. In this case, sensitivity is likely the cause.

What Are the Signs of a Cavity?

A cavity is a damaged spot in your tooth’s enamel. It creates a small hole or opening. Cavities form when plaque (a sticky film of bacteria) produces acids that wear away enamel over time.

Signs that may point to a cavity include

  • A lingering ache or dull tooth pain, even without a trigger
  • Pain when biting or chewing
  • Sensitivity that gets worse over time
  • A visible hole or dark spot on your tooth
  • Bad breath or a bad taste in your mouth

Cavities don’t always cause pain in the early stages, which is why regular dental checkups are key for catching them early.

How to Tell the Difference

The key difference lies in how the pain feels and how long it lasts. Sensitivity often causes a quick, sharp discomfort that fades once the trigger, such as something hot, cold, or sweet, disappears. Pain from a cavity usually lasts a long time or gets worse. This is especially true when you chew or bite down.

When in doubt, the safest choice is to visit your dentist. What feels like mild sensitivity could be the early stages of decay.
