Dental Crowns: When You Need One and What to Expect

What is a dental crown?

A dental crown is a custom-made cap that fits over a tooth, fully covering it above the gumline. It restores a tooth that is too damaged for a simple filling, protecting it and making it look and function like a natural tooth.

When do you need a dental crown?

• After a root canal, to protect a brittle tooth.
• For a cracked, chipped or weakened tooth.
• When a filling is too large for the tooth to support.
• To restore a badly worn or misshapen tooth.
• To anchor a dental bridge or cover an implant.

Types of dental crowns

• Metal-ceramic (PFM) — strong with a natural-looking surface.
• Zirconia — very durable and highly natural in appearance.
• All-ceramic — excellent aesthetics for front teeth.

Your dentist recommends the best material based on the tooth's position and function.

What to expect during the procedure

1. Preparation — the tooth is shaped and an impression taken.
2. Temporary crown — placed while the permanent one is made.
3. Fitting — the custom crown is checked and cemented.

The procedure is done under local anaesthesia and is painless.

Caring for your crown

Brush and floss around the crown as you would a natural tooth, avoid chewing very hard objects, and keep up regular check-ups. With good care, crowns can last 10–15 years or more.
