Have you ever wondered why your teeth feel sensitive or why cavities form, even if you brush every day? At Bow Island Dental Centre, we often hear patients use the terms erosion and decay interchangeably. While both harm your enamel, they happen in very different ways—and knowing the difference can help you protect your smile.
What Is Tooth Decay?
Tooth decay (also called cavities) happens when bacteria in your mouth feed on sugars from food and drinks. These bacteria produce acids that slowly eat away at your enamel, eventually causing cavities.
Common signs of decay include:
- Dark spots or holes in teeth
- Sensitivity to sweets
- Pain when chewing
Risk factors include poor brushing habits, frequent snacking, and sugary diets.
What Is Tooth Erosion?
Tooth erosion, on the other hand, isn’t caused by bacteria. Instead, it’s the direct wearing down of enamel by acid. This acid often comes from:
- Acidic drinks like soda, citrus juice, or sports drinks
- Stomach acid (acid reflux, vomiting)
- Certain medications
Signs of erosion include:
- Teeth that look smooth, shiny, or thinner at the edges
- Sensitivity to hot and cold
- A more translucent appearance
How to Protect Your Teeth
The good news? With the right habits, you can lower your risk of both erosion and decay.
- Brush twice daily with fluoride toothpaste
- Floss once a day
- Limit sugary foods and drinks
- Rinse with water after acidic drinks
- Wait 30 minutes before brushing after having something acidic
