When you have a damaged or decayed tooth, your dentist might recommend either a filling or a crown. Both restore tooth function, but they're used in different situations. Understanding the differences helps you make informed decisions about your dental care.
What Are Fillings?
Fillings repair small to moderate cavities or minor tooth damage. The dentist removes decayed material and fills the space with composite resin, amalgam, or other materials. Fillings are completed in one visit, preserve most of your natural tooth structure, and are relatively inexpensive ($150-$400).
What Are Crowns?
Crowns are caps that cover the entire visible portion of a tooth. They're used for extensively damaged teeth that fillings can't adequately restore. Crowns require removing more tooth structure and typically need two visits (or one with same-day crown technology). They cost more ($800-$2,500) but provide superior strength and protection.
When Fillings Are Appropriate
Fillings work well for:
- Small to moderate cavities
- Minor chips or cracks
- Teeth with adequate remaining structure
- Cosmetic improvements to front teeth
- Situations where preserving tooth structure is priority
When Crowns Are Necessary
Crowns are needed for:
- Large cavities affecting more than half the tooth
- Teeth with multiple old fillings or extensive damage
- Teeth that have had root canal treatment
- Severely cracked or broken teeth
- Teeth worn down from grinding
- Dental implant restorations
- Cosmetic improvements requiring significant reshaping
Longevity Comparison
Fillings typically last 5-15 years depending on size, location, and material. Composite fillings last 5-7 years, while amalgam can last 10-15 years. Crowns generally last 10-15 years or longer with proper care. Crowns better protect weakened teeth from further damage.
The Procedure Difference
Fillings are straightforward: numb the area, remove decay, fill and shape the material, done in 30-60 minutes. Crowns require more steps: numb the area, remove decay and shape the tooth, take impressions, place a temporary crown, then cement the permanent crown at a second visit (or complete in one visit with CEREC technology).
Cost Considerations
Fillings cost significantly less upfront but may need replacement sooner. Crowns cost more initially but last longer and better protect compromised teeth. Insurance typically covers both, though coverage percentages vary. Consider long-term value, not just immediate cost.
Can a Filling Be Upgraded to a Crown Later?
Yes, if a filled tooth develops additional problems or the filling fails, it can be crowned later. However, it's often better to crown a severely damaged tooth initially rather than risk filling failure and potential tooth loss.
Your dentist recommends fillings or crowns based on the extent of damage and the tooth's structural integrity. Trust their professional judgment - they want to preserve your natural teeth while ensuring long-term success.
