Three Habits That Destroy Your Teeth Over Time

Three Habits That Destroy Your Teeth Over Time

By Dr. Cohen, DDS

Most dental problems don’t come from one big mistake—they come from small daily habits that slowly wear your teeth down. The good news? These habits are completely within your control.

Here are three of the most common ones we see.

1. Sugar (It’s Not Always What You Think)

Sugar gets a bad reputation—and for good reason—but sugar by itself, when consumed responsibly, does not automatically cause cavities.

Problems arise when:

• Sugar is consumed frequently

• Sugar is eaten between meals

• Sugar is allowed to sit on teeth for long periods

Bacteria in your mouth feed on sugar and produce acid, which leads to enamel breakdown and cavities.

It’s also important to know that sugar is often hidden in foods people assume are harmless. For example, milk contains a natural sugar called lactose. While it’s not the same as added table sugar, frequent exposure without proper oral hygiene can still contribute to decay.

The key is moderation, timing, and brushing—not complete avoidance.

2. Soda (Yes, Even Diet Soda)

Soda is one of the most damaging beverages for teeth—not just because of sugar, but because of acid.

Both regular and diet sodas contain:

• Carbonic acid

• Phosphoric acid

These acids are what give soda its sharp, tangy taste—but they also erode tooth enamel over time. Diet soda may not have sugar, but the acid alone can still weaken your teeth and make them more vulnerable to decay and sensitivity.

Frequent sipping throughout the day is especially harmful.

3. Using Your Teeth Like Tools

This habit seems harmless—but it causes a surprising amount of damage.

Teeth are not:

• Scissors

• Bottle openers

• Tools for tearing packaging

Using your teeth this way can lead to:

• Cracks

• Chips

• Broken teeth or dental work

These issues often happen suddenly, but the damage builds up over time.

The Bottom Line

You may only see your dentist every six months, but what truly determines your dental health is what you do every day.

• Be mindful of sugar

• Limit acidic drinks like soda

• Use your teeth only for what they’re meant to do

Small habit changes now can protect your teeth for years to come—and they’re all within your control.
