When a tooth becomes damaged or decayed, your dentist may recommend a restoration to bring it back to health. Two common solutions—dental crowns and fillings—serve different purposes and are not interchangeable in every situation. So how do you know which is right for you?
In this video, Dr. Grimshaw explains why choosing a crown over a filling can be the smarter, longer-lasting choice—especially when a tooth has already been compromised. If you’ve ever wondered whether you need a crown or if a filling would be enough, this article will help you understand each option’s key differences and long-term impact.

What Is a Dental Filling—and When Is It Enough?
A dental filling is a restorative material used to repair a tooth affected by decay or minor damage. It works by filling the cavity after removing the decayed portion, restoring the tooth’s function and appearance.
Fillings are ideal when the damaged area is small to moderate in size. They’re quick to place, cost-effective, and blend naturally with your tooth. However, they depend on the surrounding tooth structure for support. That’s where their limitations begin.
A filling does not reinforce the entire tooth but patches a problem area. If too much of the tooth has been lost or weakened, the restoration may not hold up to the pressure of daily biting and chewing over time.
Why Fillings Aren’t Always the Best Long-Term Solution
When a tooth already has a large or multiple fillings, the remaining natural structure becomes more vulnerable. As the tooth flexes under pressure, small cracks or fractures can form around the edges of the filling. Over time, this may lead to bigger problems, including broken teeth or even the need for extraction.
Dr. Grimshaw often sees patients return with a damaged tooth that once had a large filling. In many cases, the issue could have been avoided with a crown placed earlier.
Fillings can also break down over time, leading to leakage and recurrent decay beneath the surface. This puts both the filling and the tooth at risk, and may eventually require more extensive treatment.
Why Crowns Provide Better Strength and Protection
Unlike fillings, crowns don’t rely on the remaining tooth structure for strength—they provide it. A crown is a full-coverage restoration that encases the entire visible portion of the tooth, distributing force more evenly and protecting it from breakage.
In Dr. Grimshaw words: “The truth is, [you’re] better off with a crown. The crown strengthens the tooth [and] will protect it better from breakage.”
Crowns are custom-made to fit your mouth precisely. They’re designed from durable materials like porcelain, zirconia, or metal alloys and are bonded over the prepared tooth to restore its shape, appearance, and function. When a tooth is significantly compromised, a crown acts as a protective shell that safeguards it from further damage.
When Is a Crown the Right Choice?
Crowns are not always necessary, but in certain situations, they are strongly recommended for long-term protection and success. Your dentist may suggest a crown if:
- A tooth has a large cavity that compromises more than half of the tooth.
- The tooth has already had one or more large fillings.
- There is visible cracking or signs of stress.
- The tooth has undergone root canal treatment.
- A filling has failed or is no longer protecting the tooth adequately.
In each scenario, placing a crown can prevent a more serious dental emergency—like a tooth fracture that extends below the gumline, which could require extraction or more invasive treatments.
Comparing Lifespan and Durability: Fillings vs. Crowns
One of the biggest differences between fillings and crowns is how long they last and how well they hold up under daily wear. Fillings, especially composite ones, generally last between 5 and 10 years. Their longevity depends on the size of the filling, bite forces, and oral hygiene habits.
On the other hand, crowns can last 10 to 15 years or longer with proper care. Because they cover and reinforce the entire tooth, they are better suited for high-stress areas like molars or teeth that have experienced significant wear.
Choosing between a crown and a filling should always consider long-term function, not just short-term cost. Investing in the right restoration today can save you from more expensive procedures tomorrow.
What Happens If You Wait Too Long to Get a Crown?
Delaying a crown can result in consequences that are more costly and complex. A weakened tooth with a large filling can crack unexpectedly, causing pain or requiring emergency treatment. If the fracture runs deep enough, the tooth may no longer be restorable and will need to be removed.
Here are a few common risks of postponing recommended crown treatment:
- Sudden fracture of the tooth
- Increased risk of root canal infection
- Emergency dental visits due to pain or breakage
- Potential need for extraction and replacement with a bridge or implant
Being proactive by choosing a crown when recommended can help preserve your natural tooth for years to come.
Watch: Dr. Grimshaw Explains the Benefits of Choosing a Crown
In this video, Dr. Grimshaw outlines why crowns often offer better long-term value than fillings—especially in teeth that have already been restored. Her explanation provides a clear and relatable understanding of how crowns protect teeth from future problems.
Patients frequently ask whether a crown is really necessary. This video, backed by experience and results, helps answer that question from a dentist’s perspective.
The Right Restoration Can Save Your Tooth
Choosing between a crown and a filling is more than just fixing a cavity—it’s about protecting your tooth for the future. While fillings are appropriate for small areas of decay, they have limits. When a tooth is already structurally compromised, a crown offers the strength and coverage needed to avoid further damage.
At Kuhn Dental Associates, we don’t just repair teeth—we help you make informed decisions that protect your smile long term. If you’ve been advised to get a crown, it’s likely because your dentist sees signs that your tooth needs more support than a filling can provide.
Final Thoughts: Invest in Long-Term Tooth Protection
Fillings serve an important purpose, but they aren’t designed to reinforce a tooth under serious stress. On the other hand, crowns provide comprehensive protection and are often the smarter choice when damage is significant or recurring.
