What Is the Difference Between Fillings and Crowns?

Dental Fillings vs Crowns: How They’re Used to Restore Smiles

Dental fillings and dental crowns are popular tooth restoration options designed to enhance your smile while protecting your teeth from further damage or decay. However, these restorative treatments are not interchangeable. At Restoration Dental, we want our patients to understand the differences between our restoration dentistry options, so they have the information they need to make the right dental healthcare decisions for their needs. Learn more about dental fillings and crowns, and discover which one is best suited for you.

What Is a Dental Filling?

Tooth decay can cause holes or cavities in your teeth. If left unchecked, the cavity can become deep enough to reach the tooth root, causing an infection. When the cavity is caught early enough, a dental filling is placed. A dental filling is a common type of restorative dentistry option designed to protect your teeth from further decay. There are different types of fillings, including composite resin, amalgam, and porcelain. The material used depends on the patient’s personal preference, budget, and the cavity’s location. Once the filling is set, you can use and care for your tooth as you normally would.

What Is a Dental Crown?

A dental crown is a custom-made “cap” that fits over a damaged, weakened, or heavily restored tooth. It helps protect the tooth while restoring a natural look and feel. Crowns can be made from durable, natural-looking materials, so they blend comfortably with your smile while helping you bite and chew with confidence.

Dental Fillings vs Dental Crowns: Major Differences

Though dental fillings and dental crowns are both restorative dental options, there are numerous differences between the two. For patients, knowing the differences will help them better understand what to expect during their appointment to alleviate anxiety and enjoy a more pleasant experience:

• Damage: Fillings are used for minor cavities or cracks. Dental crowns are used when the root of the tooth is healthy, but the tooth’s crown is severely damaged or decayed.
• Procedure and Time: A dental filling is usually completed in one visit and involves removing the decayed area, filling the space, and shaping the tooth. A dental crown typically requires more preparation and may take two visits, especially if a custom crown needs to be made by a dental lab. However, one day crowns are available.
• Cost: Dental fillings are generally more affordable because they use less material and require a simpler procedure. Dental crowns usually cost more because they cover the entire visible portion of the tooth and are custom-made for strength, fit, and appearance.
• Lifespan: With good brushing, flossing, and routine dental visits, fillings can last several years before needing repair or replacement. Crowns are designed for added durability and may last longer, especially when patients avoid chewing hard objects and practice consistent oral hygiene.

When Is a Dental Filling the Preferred Tooth Restoration Option?

A dental filling is often the preferred option when tooth damage is minor to moderate, and there is enough healthy tooth structure remaining. Fillings are commonly used to repair small cavities, chips, or areas of decay before they become more serious. Because fillings are less invasive than crowns, they can be a simple, effective way to protect your smile and maintain your natural tooth.

When Is a Dental Crown the Preferred Tooth Restoration Option?

A dental crown is often the preferred option when a tooth has more extensive damage or decay that a filling cannot properly repair. We may recommend a crown if the tooth is cracked, weakened, worn down, or has had a large filling or root canal treatment.

Which Tooth Restoration Option Is Right for You?

Choosing the right tooth restoration option normally comes down to the extent of the damage and the best way to protect the damaged tooth in the future. When you schedule your checkup, we will examine your tooth and recommend the appropriate treatment to restore your smile. If your tooth has been damaged due to decay or injury, contact our office immediately to schedule your dental examination.

Dental Filling and Dental Crown FAQ

Is a Crown Stronger Than a Filling?

Yes. Crowns are generally stronger than fillings. A filling repairs a smaller area, while a crown provides added support for teeth that are weakened, cracked, or heavily damaged.

Can a Filling Be Replaced With a Crown Later?

Yes. If a tooth with a filling becomes weak, cracked, or develops more decay, your dentist may recommend replacing the filling with a crown.

How Long Do Dental Fillings Typically Last?

Dental fillings can last several years with good oral hygiene, including brushing, flossing, using mouthwash, and regular dental checkups.

How Long Do Dental Crowns Typically Last?

Dental crowns often last many years with proper care. Brushing, flossing, and routine dental visits can help extend the life of your crown.
