Crown vs Cap difference
When it comes to dental restorations, the terms “crown” and “cap” are often used interchangeably. But is there really a difference? If you’ve ever wondered about the difference between a crown and a cap, you’re not alone. In this detailed article, we’ll explore the truth behind these terms, when each is used, and what you need to know before getting one.
🦷 What is a Dental Crown?
A dental crown is a custom-made restoration that fully encases a damaged or decayed tooth above the gumline. It is used to restore the tooth’s shape, strength, function, and appearance.
Common Uses of Crowns:
- Protect a weak or cracked tooth
- Restore a broken or severely worn-down tooth
- Cover a tooth after a root canal treatment
- Support a dental bridge
- Cover a dental implant
- Improve the cosmetic appearance of a tooth
🦷 What is a Dental Cap?
A dental cap is simply another term for a dental crown. The term “cap” is more commonly used by patients and laypeople, whereas “crown” is the clinical and professional term used by dentists.
✅ Important Note:
There is no functional or structural difference between a cap and a crown. They are two names for the same dental restoration.
