If your dentist has recommended a tooth crown and you’re unsure what it means, you’re not alone. Dental crowns are one of the most common restorative procedures, but for first-time patients, the terminology and process can seem confusing. This guide will walk you through everything you need to know—from what a crown is and why it’s used to the types available and what to expect before, during, and after treatment.
Whether you’re getting a crown to fix a damaged tooth or as part of a smile makeover, understanding your options is the first step toward a healthier, more confident smile.
What Is a Tooth Crown?
A tooth crown, also known as a dental crown or cap, is a custom-made restoration that covers the entire visible surface of a tooth above the gum line. Think of it as a “helmet” for a damaged or weakened tooth, restoring its shape, size, strength, and appearance.
Crowns can be made from various materials—including porcelain, zirconia, metal alloys, and composite resin—each with its own pros and cons depending on the patient’s needs.
Why Might You Need a Crown?
Tooth crowns are used for both functional and cosmetic purposes. Common reasons include:
- To restore a broken or severely worn tooth
- To protect a weak tooth from fracture (e.g., after a root canal)
- To hold together parts of a cracked tooth
- To support a tooth with a large filling
- To cover discolored or misshaped teeth
- To anchor a dental bridge or cover a dental implant
- Porcelain-Fused-to-Metal (PFM) Crowns
- Combines strength and aesthetics
- Metal base provides durability
- Porcelain layer mimics tooth color
- May show a grey line at the gum over time
- All-Ceramic or Porcelain Crowns
- Highly aesthetic and metal-free
- Best for front teeth
