Dental fillings and dental crowns are two common restorations for cavities, chips, cracks, and other types of tooth damage. While fillings typically work well to repair small areas of decay or damage, crowns are often necessary when a tooth needs more protection and structural support.
At VIP Smiles, we want you to have all the information you need to make informed decisions about your oral health and dental restorations. If you know you need a restoration but aren’t sure which kind yet, keep reading to learn the major differences between fillings and crowns, which situations are best for each restoration, and how to know when a dental crown is necessary instead of a filling.

What Is a Dental Filling?
Dental fillings are exactly what they sound like: They’re used to fill in areas of damage or decay on a tooth, including small cavities and minor chips or cracks. In the past, fillings were typically made of a metal amalgam, but more and more dentists have started using a tooth-colored composite resin instead for a more natural look.
The benefits of dental fillings are that they’re a more conservative treatment than a crown, the procedure is faster, and it typically costs less. However, fillings may not be sufficient for teeth with extensive damage.
What Is a Dental Crown?
A dental crown is a tooth-shaped cap that covers the entire visible portion of the natural tooth. They’re used in cases of severe decay or cracks, after root canal treatment, or when the tooth structure is weakened. The crown’s job is to protect the tooth from further damage and give it additional structural support.
The benefits of dental crowns include improved tooth strength and durability, long-lasting protection against future damage, a natural-looking appearance, and better chewing function.

7 Signs You May Need a Dental Crown
Now that you know the basics of dental crowns and fillings, let’s take a look at some signs you may need a crown rather than a filling.
1. Large Areas of Tooth Decay
Extensive decay weakens the tooth. Large fillings may not provide enough support if decay is extensive, increasing the risk of tooth fracture. Because dental crowns reinforce the remaining tooth structure, they’re more suitable for teeth with larger areas of decay.
2. Cracked or Fractured Teeth
Cracked teeth can cause pain when chewing and temperature sensitivity. Fillings may not be enough to stabilize a crack. Crowns, on the other hand, help hold the tooth together and prevent further splitting.
3. A Filling Keeps Falling Out or Failing
If you’ve had a filling that has repeatedly fallen out or caused other issues, it may mean that there’s not enough healthy tooth structure to keep it in place. Dental crowns provide a more durable long-term solution.
4. You Have a Very Large Existing Filling
Older, large fillings can weaken the surrounding tooth enamel, increasing the risk of tooth fracture over time. Because of this, crowns are often recommended when you’ve had a large filling for several years.
5. Tooth Pain When Chewing
Pain when biting may indicate structural weakness or cracks in your tooth. Crowns can stabilize the tooth and reduce discomfort; however, it’s always important to consult with your dentist to determine the root of the problem.
6. You’ve Had a Root Canal
Root canals remove the inflamed or infected pulp from the inside of the tooth, which can leave the tooth more brittle. Molars and premolars often require dental crowns after root canals to protect the tooth from breaking and restore normal function.
7. Worn Down Teeth
Teeth can become worn due to teeth grinding (bruxism), acid erosion, or simply time and age. If a tooth has experienced significant wear, a crown can restore its shape, strength, and function.
8. Broken Cusps or Chipped Teeth
Cusps are the raised points on the crowns of your teeth. They play a crucial role in chewing. When they’re broken or your teeth are chipped, you may require more than a filling. A dental crown can be placed to restore full functionality and appearance.

Choosing Between a Crown and Filling
The choice between a dental crown and a filling is important. If you get a filling when a crown would’ve been more suitable, you have a higher likelihood of tooth fracture, repeated dental work or repairs (and the corresponding cost of additional treatment), and increased sensitivity or discomfort.
Your dentist will perform an examination and X-rays to evaluate the remaining healthy tooth structure, consider the bite pressure on the tooth, and discuss your goals and budget to determine which restoration is right for you.
