When it comes to restoring a damaged or decayed tooth, two of the most common treatments are dental crowns and fillings. Both are effective solutions, but each has specific uses and benefits depending on the extent of the damage. Understanding the difference between the two can help you feel more confident when it’s time to make a decision about your dental treatment.
At Phelan Dental in Oakville, we’re committed to providing personalized care and guiding you through the best options for your oral health. In this blog, we’ll break down the differences between dental crowns and fillings, and explain how your dentist decides which treatment is right for you.
What Are Dental Fillings?
A dental filling is typically used for small to moderate cavities or damage caused by tooth decay. Fillings restore the shape and function of a tooth that has been compromised by decay, allowing you to chew and speak normally.
What to Expect:
- The dentist removes the decayed portion of the tooth, cleans the area, and then fills it with a material such as composite resin, amalgam, or porcelain.
- Fillings can usually be completed in a single visit and require minimal preparation.
Why It Helps:
- Fillings are an excellent choice for small cavities or minor damage, providing a quick and cost-effective way to restore your tooth to full function.
- Composite fillings blend in with the natural color of your teeth, making them an aesthetic option for visible areas.
What Are Dental Crowns?
A dental crown is a cap that covers a damaged or weakened tooth to restore its strength, shape, and function. Crowns are often used for more extensive damage, such as large cavities, cracks, or teeth that have undergone a root canal treatment.
What to Expect:
- The dentist prepares the tooth by removing any damaged or decayed portion, and then a custom crown is created to fit over the tooth. Crowns can be made from various materials, including porcelain, ceramic, metal, or a combination.
- The process typically requires two visits: one for preparation and impressions, and a second for placing the crown.
Why It Helps:
- Crowns are ideal for restoring teeth that are severely damaged or weakened, helping to prevent further damage and preserve the tooth’s natural structure.
- Porcelain crowns offer a natural look and are often used for visible teeth, while metal crowns are more durable and suitable for back teeth that endure heavy chewing forces.
When Are Fillings the Best Option?
Fillings are generally used for smaller dental issues, such as cavities or minor cracks, where the damage doesn’t extend deeply into the tooth structure. Here are some situations where fillings may be the best choice:
- Small to medium cavities: When the damage is contained to the outer layers of the tooth.
- Minimal tooth structure loss: When there is enough healthy tooth remaining to support a filling.
- Aesthetic concerns: Composite fillings can be matched to the color of your natural teeth, making them ideal for filling cavities in visible areas like the front teeth.
What to Expect:
- Filling placement is relatively quick, often requiring just a single visit.
- After removing the decay, the dentist will place the filling and smooth it out to restore the tooth’s shape and function.
Why It Helps:
- Fillings are a cost-effective solution for small cavities or cracks that don’t require extensive restoration. They preserve the majority of your natural tooth structure while providing functional and aesthetic benefits.
When Are Crowns the Best Option?
Crowns are necessary when a tooth has extensive damage that a filling cannot adequately repair. They’re also ideal for teeth that have undergone a root canal or for those that are weakened or cracked. Here are some scenarios where a crown may be the best option:
- Large cavities or decay: When more than half of the tooth is decayed or damaged.
- Root canal treatment: After a root canal, the tooth may become weak and brittle, requiring a crown for strength and protection.
- Cracked or broken teeth: Teeth that are fractured or have large cracks can benefit from the added support a crown provides.
- Cosmetic concerns: For visible teeth with extensive damage, a porcelain crown can restore both function and aesthetics.
What to Expect:
- The dentist will remove the decayed or damaged portion of the tooth and take impressions to create a custom crown.
- Crowns are placed over the tooth to restore its shape, size, and function, ensuring that it can handle the normal pressures of chewing and biting.
Why It Helps:
- Crowns provide long-term durability and protection for teeth that are extensively damaged, allowing them to continue functioning properly and preventing further damage or tooth loss.
How Dentists Decide Between Crowns and Fillings
The decision between a crown and a filling depends on the severity of the damage to the tooth, the location of the tooth, and the overall condition of the tooth structure. Here are the key factors dentists consider when making the decision:
1. Amount of Tooth Structure Lost:
- If the tooth has lost a significant amount of its structure due to decay or damage, a crown may be necessary to provide the strength and support it needs.
- If only a small portion of the tooth is affected by decay, a filling may be sufficient to restore the tooth.
2. Tooth Location:
- Fillings are commonly used for cavities in the back teeth (molars) where the damage is minor.
- Crowns are often used for front teeth or heavily-used molars that need added strength and protection.
3. Longevity and Durability:
- Crowns are more durable and long-lasting, making them ideal for teeth that experience a lot of pressure from chewing.
- Fillings are typically sufficient for smaller cavities but may wear down over time, especially in areas that experience heavy chewing.
4. Aesthetic Concerns:
- If the tooth is visible and has significant damage, a porcelain crown can provide a more natural, aesthetically pleasing result.
- Composite fillings can blend with the natural tooth color and are often used for visible teeth with small cavities.
5. Root Canal Treatment:
- After a root canal, the tooth becomes brittle and needs additional support, so a crown is generally recommended to protect it from further damage.
What to Expect During the Treatment Process
For fillings, the process is typically completed in a single visit:
- The dentist removes the decayed portion of the tooth, cleans the area, and places the filling.
- The filling is shaped to match the natural contours of the tooth.
For crowns, the process usually involves two visits:
- The first visit is for tooth preparation, including removing decay and taking impressions to create a custom crown.
- The second visit is for placing the crown and ensuring a comfortable fit.

FAQs About Crowns vs. Fillings
How long do crowns and fillings last?
Fillings typically last around 5-10 years, depending on the material used and the location of the filling. Crowns can last 10-15 years or longer with proper care.
Are crowns more expensive than fillings?
Yes, crowns are generally more expensive than fillings because they require more time and materials to create and place.
Can a filling fail and need a crown?
If a filling becomes loose or the tooth around it becomes damaged, it may need to be replaced with a crown for better protection and strength.
