Dental Filling vs Crown: What Is the Difference?
Fillings and crowns both restore teeth, but they solve different levels of damage.
At a glance
- Fillings usually repair smaller cavities or minor tooth damage.
- Crowns may be recommended when a tooth needs more coverage or strength.
- An exam and X-ray help confirm the right option.
A filling repairs a smaller area
A filling removes decay or damaged tooth structure and seals the tooth with restorative material. It is usually considered when the remaining tooth is strong enough to support the repair.
A crown covers and protects more tooth structure
A crown may be recommended when a tooth is cracked, weakened, heavily restored, or at higher risk of breaking. It covers the tooth to restore function and protection.
The best option depends on the tooth
The office should explain the X-ray findings, how much tooth structure remains, and the practical tradeoffs before treatment is scheduled.
