A dental crown, often called a cap, is a tooth-shaped covering placed over a damaged tooth to restore its strength, shape and appearance.
When Is a Crown Needed?
- After a root canal, to protect the weakened tooth.
- A large cavity where a filling will not hold.
- A cracked or heavily worn tooth.
- To cover a discolored or misshapen tooth.
- To cap a dental implant.
Common Types of Crowns
- Metal-ceramic (PFM): a metal base with a tooth-colored porcelain layer.
- Zirconia: strong, tooth-colored and popular for natural looks.
- All-ceramic: highly aesthetic, often used for front teeth.
- Metal crowns: very durable, usually used at the back.
Your dentist will recommend a material based on the tooth position, your bite, and your aesthetic needs.
The Process
- Examination and X-rays.
- The tooth is shaped and an impression or digital scan is taken.
- A temporary crown protects the tooth while the final one is made.
- The permanent crown is checked for fit and bite, then cemented.
Caring for Your Crown
Brush and floss normally, paying attention to the gum line. Avoid biting hard objects like ice or pen caps, and attend regular check-ups. With good care, crowns can last many years.
