Cavity vs Enamel Erosion: Understanding the Difference in Your Teeth
dentalhealth
Cavities and enamel erosion both affect tooth enamel, but they have different causes. Here's how to tell them apart.
Cavities and enamel erosion can feel similar, but they start in different ways and are managed differently.
What a cavity is
A cavity comes from bacteria in plaque. They make acid from sugars and starches, and that acid creates a localized hole in the tooth.
What enamel erosion is
Erosion comes from acid in food and drinks, such as citrus, soda or wine, wearing enamel away directly. It tends to be more widespread, and teeth can look smooth, shiny or slightly yellow. Read more in our post on enamel erosion, acidic foods and tooth sensitivity.
Key differences
- Cause: a cavity involves bacteria; erosion involves dietary or stomach acid.
- Pattern: a cavity is usually a spot; erosion tends to affect several teeth.
- Treatment: a cavity needs a filling once a hole forms; erosion focuses on protecting remaining enamel.
What they share
Both can cause sensitivity. Our tooth sensitivity guide outlines possible causes, and in-office treatments for sensitive teeth may help.
