What Causes Cavities? Here Are the Most Common Culprits

Written by Dr. Holly Nadji • May 8 • 1 minute read

Cavities—also known as tooth decay—are one of the most common dental issues. But the good news? They’re also one of the most preventable! Understanding what causes them is the first step toward a healthier smile.

Top Causes of Cavities:

1. Sugary Foods & Drinks
Sugar feeds the bacteria in your mouth, which produce acid that wears down tooth enamel and leads to decay.

2. Poor Brushing & Flossing Habits
Skipping brushing or flossing allows plaque and food debris to build up, giving decay a head start.

3. Acidic Foods & Beverages
Sodas, citrus, and sports drinks can erode enamel over time, making teeth more vulnerable to cavities.

4. Dry Mouth
Saliva helps neutralize acids and wash away particles. Less saliva = higher cavity risk.

5. Not Seeing the Dentist Regularly
Cavities can form silently. Regular checkups help catch decay early—before it turns into a bigger problem.
