Dental fillings and crowns are two treatments for restoring damaged or decayed teeth. While both protect and restore function, they are used for different levels of tooth damage.
This guide will analyze how fillings and crowns work, their cost, durability, and aesthetic appeal, and when you might need one over the other.
What Is a Dental Filling?
A dental filling is a restorative treatment to remedy minor cavities or small areas of decay. It involves removing the decayed portion of the tooth and filling the space with a durable material to restore strength and function.
How Fillings Work
- Your dentist removes decayed tooth material.
- The space is cleaned and prepared.
- A filling material is placed into the cavity and shaped to match the tooth’s natural structure.
- The filling is hardened using a curing light (for composite fillings) or sets naturally (for materials like amalgam).
Types of Fillings
Different materials are used for dental fillings, each with its benefits:
- Composite (Tooth-Colored) Fillings: Blend with teeth, making them ideal for visible areas.
- Amalgam (Silver) Fillings: Durable and cost-effective but less aesthetic.
- Porcelain Fillings: Aesthetic and stain-resistant but more expensive.
- Gold Fillings: Durable but expensive and less common.
When a Filling Is Suitable
There are several factors to take into account. First, the size of the decay plays a crucial role, as fillings are recommended for small to moderate areas of decay. A filling may be sufficient to restore the tooth if the tooth structure is mostly intact and with no significant damage. Another consideration is the speed and cost of the restoration – fillings are often quick and affordable compared to other treatments. Last, if you prefer a minimally invasive option that preserves more of your natural tooth structure, a filling may be the ideal choice.
What Is a Dental Crown?
A dental crown, also called a cap, is a custom-made covering that encases a damaged tooth to restore its shape, strength, and function. Crowns are used when a filling alone isn’t enough to support the tooth.
How Crowns Work
Crowns work by reshaping the tooth to remove decay and create space for the crown. An impression is then taken to ensure a custom fit and a temporary crown may be placed while the permanent one is crafted. Once ready, the permanent crown is securely cemented onto the tooth.
Types of Crowns
- Porcelain Crowns: Natural-looking and ideal for front teeth.
- Ceramic Crowns: Aesthetic and durable, great for visible areas.
- Zirconia Crowns: Extremely strong and resistant to wear.
- Metal Crowns (Gold or Silver Alloys): Durable but not tooth-colored.
- Porcelain-Fused-to-Metal Crowns: Aesthetic with a strong metal core.
When a Crown Is Appropriate
A crown is necessary when a tooth has significant decay that a filling can’t support, has been weakened by a root canal, is cracked, fractured, or worn down, or when long-term durability and protection are needed.
Dental Crown vs. Filling: Quick Comparison
| Feature | Dental Filling | Dental Crown |
| Purpose | Repairs small-to-moderate cavities | Protects and restores damaged or weak teeth |
| Tooth Structure Preserved | Minimal removal of natural tooth | Requires reshaping of the tooth |
| Severity of Damage Treated | Mild to moderate decay | Large decay, cracks, fractures, or post-root canal treatment |
| Procedure Time | 1 visit (30-60 minutes) | 2 visits (or 1 with CEREC technology) |
| Material Options | Composite, Amalgam, Porcelain, Gold | Porcelain, Ceramic, Zirconia, Metal, Porcelain-fused-to-metal |
| Durability | 5-15 years | 10-30 years |
| Aesthetic Appeal | Tooth-colored options available | Natural-looking or metal options |
| Cost Range | $100 – $500 per tooth | $800 – $2,500 per tooth |
| Insurance Coverage | Usually covered at a high percentage | Partial coverage, higher out-of-pocket cost |
| Best For | Small cavities, minimal damage | Large decay, fractures, weakened teeth, post-root canal support |
Crown vs. Filling – Which Is Best for You?
Signs You Might Need a Crown
✔ Large decay that compromises tooth strength
✔ A tooth with significant cracks or fractures
✔ A root canal-treated tooth that needs reinforcement
✔ A heavily worn-down tooth
Signs You Might Only Need a Filling
✔ Small to moderate cavities with minimal damage
✔ No structural weakening of the tooth
✔ You prefer a quick, less expensive option
When to Seek a Dentist’s Opinion
Schedule a consultation to determine the appropriate treatment plan. Your dentist will evaluate the extent of decay or damage, assess the strength and function of the affected tooth, and discuss your long-term oral health goals. This assessment will guide the dentist in recommending the most suitable treatments for your needs.
Making the Best Choice for Your Smile
A filling is often sufficient for minor decay. But if your tooth is at risk of breaking or has had significant work, a crown may be the better option.

FAQs About Dental Crowns and Fillings
Can a filling be replaced with a crown later?
If a filling becomes too large or weakens, a crown can provide additional protection.
How long do crowns and fillings last?
Fillings last 5-15 years, while crowns can last 10-30 years with proper care.
Do crowns hurt more than fillings?
The procedure for both is painless with local anesthesia, though crowns may cause some post-procedure sensitivity.
Does dental insurance cover crowns and fillings?
Most insurance plans cover a portion of the cost, but crowns often require higher out-of-pocket expenses.
Which is better: a filling or a crown?
It depends on the severity. Fillings are better for minor repairs, while crowns offer stronger, longer-lasting protection for weak teeth.
