Crown vs. Filling: Which Is Better for Damaged Teeth?
&srotate=0)
Many people think of crowns and dental fillings as being somewhat interchangeable, with the choice coming down to personal preference — but that isn’t always the case. Most often, choosing between a dental crown or a filling is guided by your dentist and will take into account the type of damage your tooth has sustained, the extent or severity of the damage, and other factors. Generally speaking, moderate damage, like small areas of decay, may be suitable for treatment with a filling, while more significant tooth decay, cracks, or teeth requiring root canal therapy will be treated and protected with a dental crown.
Again, however, your dentist will help you determine which type of dental work is most appropriate for your unique situation. At Tupelo Smiles, Dr. Richard Caron, Dr. John Kenney, and Dr. Emilie Caron Russell offer high-quality dental crowns and tooth-colored fillings, along with a full suite of advanced restorative and cosmetic dental treatments in Tupelo, MS to meet the diverse needs and goals of each patient. Keep reading for a more in-depth comparison of when a crown vs. filling is used and why.
What are dental fillings used for?
Dental fillings are commonly used to repair teeth that have minor to moderate damage, most often caused by tooth decay. After the damaged portion of the tooth is removed, the filling material is placed to restore the tooth's structure and function. Today, many patients choose tooth-colored composite fillings because they blend naturally with the surrounding teeth. Dental fillings are often used for:
- Small cavities
- Minor tooth decay
- Small chips or fractures
- Replacement of worn fillings
- Preservation of healthy tooth structure
Because fillings require less removal of healthy tooth material than crowns, they are often the preferred option when the damage is relatively limited.
Is my cavity too big for a filling?
The size and location of a cavity play a significant role in determining whether a filling will provide adequate long-term support. When a large portion of the tooth has been compromised by decay, a filling may not be strong enough to withstand normal biting and chewing forces. In these situations, a dental crown may provide a more durable solution. During your examination, our dentist will evaluate the extent of the damage and determine whether a filling can effectively restore the tooth or whether additional protection is needed.
When is a dental crown needed?
A dental crown is typically recommended when a tooth has sustained more extensive damage or requires additional structural support. Unlike a filling, which repairs a portion of the tooth, a crown covers the entire visible portion of the tooth above the gumline. Situations where a dental crown may be recommended include:
- Large cavities
- Extensive tooth decay
- Cracked teeth
- Broken teeth
- Teeth weakened after root canal therapy
- Severely worn teeth
- Replacement of failing large fillings
By fully covering the tooth, a crown can help protect it from further damage while restoring strength, appearance, and function.
Can an old filling be replaced with a tooth-colored filling?
Many patients choose to replace older fillings, particularly metal amalgam fillings, with modern tooth-colored composite materials. In some cases, replacement is performed because an older filling has worn down, cracked, leaked, or become damaged. In other situations, patients simply prefer the more natural appearance of tooth-colored restorations. During your evaluation, we can determine whether an existing filling can be replaced with a new filling or whether a crown may provide a more predictable long-term solution.
What makes a tooth filling fail and need a crown instead?
While fillings can last for many years, they are not indefinite. Over time, fillings may wear down, loosen, crack, or allow new decay to develop around the edges. Additionally, the natural tooth structure surrounding a filling may weaken over time. Common reasons a filling may eventually require replacement with a crown include:
- A filling that cracks or fractures
- New decay around an existing filling
- A cavity that has become larger
- A tooth that develops a crack
- Excessive wear on the restoration
- Loss of significant tooth structure
When a filling can no longer adequately support the remaining tooth, a crown may be recommended to provide greater protection and durability you can rely on over the long term.
