What’s the Difference Between a Cap and a Crown?

March 13, 2025

What is a dental cap, and what is a dental crown? Although some use the terms interchangeably, there are practical and aesthetic differences between caps and crowns.

With that said, what’s the difference between a cap and a crown? You’ve come to the right place.

Dental Crowns

Tooth coverings placed entirely over treated teeth to restore their size, shape, or appearance are called crowns. Dental crowns are frequently used to treat damaged and cracked teeth, as well as root canal-treated teeth. They can also cover and protect dental implants. Custom-made crowns are fitted throughout multiple appointments and are often more expensive than dental caps.

Dental Caps

Some prefer dental caps for damaged premolars and molars, as the procedure is less invasive. Dentists typically recommend dental caps vs. crowns to treat traumatized, sensitive, or discolored teeth caused by cracks, fractures, or decay. Tooth caps, also called inlays or onlays, are similar to crowns, but they only cover part of a tooth’s surface, whereas crowns cover the whole tooth. The materials used in dental caps are similar to those used in crowns, but they’re usually only made to protect one side of the tooth.

Comparing Cap vs Crown for Teeth

The following are reasons a dentist may recommend caps vs. crowns for root canals and other dental issues:

  • Repairing a cracked tooth or restoring a damaged tooth
  • Protecting the placement of a large filling
  • Covering discoloration or an implant
  • Holding a dental bridge in place

The durability of caps vs. crowns varies based on the materials used.

Differences Between Caps and Crowns

One significant difference between cap and crown procedures is the amount of healthy enamel that must be removed. Because they cover less surface area, the procedure for getting a cap is usually less time-consuming, expensive, and invasive than the procedure for getting a crown.

Aesthetic differences in caps and crowns are generally minor, as both can be matched to surrounding teeth.

Cap or Crown, Which is Better?

When considering the pros and cons of dental crowns, it’s best to consult with a certified dental professional.

Durability of Caps vs. Crowns

Although the lifespan of dental caps is shorter than that of crowns, both can last many years if they’re cared for properly. Depending on their placement and how well you care for them, they may even last a lifetime.

Is a Dental Cap Permanent?

Crowns must be bonded to the treated tooth, so it’s difficult to remove them without fitting an entirely new dental crown. Dental caps are easier to remove and replace.

Summary: Compare Caps vs Crowns for Teeth

What’s the difference between a cap and a crown? Let’s review the main differences.

What Is a Dental Cap?

When weighing the pros and cons of dental caps, note that the materials used and the procedures for getting a cap make them unique. They typically cover significantly less surface area than a crown. The lifespan of dental caps depends on their materials and care. The cost of dental caps is lower than the cost of dental crowns.

What Is a Dental Crown?

The procedures and materials used in dental crowns set them apart from dental caps. Most notably, crowns cover the entire treated tooth. The cost of a dental crown is higher compared to a cap, as the procedure for getting a crown is more time-consuming. However, the lifespan of dental crowns is often longer.
