What’s the Difference Between a Dental Crown and a Filling?

If you’ve been told you need a dental crown—or maybe just a filling—you might wonder what really sets them apart. Both fix damaged teeth. Both restore function. But they’re not interchangeable, and the right one depends on how much of the tooth is affected.

At Norman, Obeck, & Foy Dentistry in Richmond, VA, Dr. Andrew Norman, Dr. Kurt Obeck, and Dr. Randall Foy help patients understand their treatment options without the guesswork. Let’s break down what each option does—and when one might be better than the other.

Fillings: Small Repairs, Big Impact

Fillings are used when there’s minor to moderate decay. After removing the damaged part, the tooth is filled with composite material to restore shape and function. Fillings are ideal when most of the natural tooth remains strong.

They’re quick to place, preserve more natural structure, and work well for small cavities or minor chips. But if too much tooth is gone, a filling won’t hold up long-term.

When is a Cavity Too Big for a Filling?

Not all cavities are created equal. A small one affects only the outer enamel and can usually be treated with a simple filling. But if the cavity spreads across more of the tooth or extends deep toward the nerve, it’s considered large or deep.

In these cases, a filling might not hold up well over time. The tooth can become weakened, and the risk of cracking or further decay goes up. That’s when a crown is often the better option—it protects what’s left and helps the tooth stay strong during daily use.

Crowns: Full Coverage Protection

A dental crown covers the entire visible part of the tooth. It’s used when a tooth is cracked, worn down, or has a large cavity that a filling can’t support.

Crowns offer strength and structure. They’re often recommended after root canals, large fillings, or trauma. While a crown takes more time and prep, it lasts longer and protects teeth under more pressure—like chewing or grinding.
