Dental crowns are one of the most common restorations we place, yet they are surrounded by myths. Let's clear a few up.

A crown is a full-coverage cap, usually made of porcelain or zirconia, that sits over the remaining tooth structure like a helmet. It restores strength, shape and function — and when made well, it is indistinguishable from a natural tooth.

You may need a crown after a root canal, to protect a cracked tooth, to rebuild a badly worn or decayed tooth, or to cover a dental implant. We also use crowns for cosmetic reasons, to dramatically improve the appearance of a single tooth.

Modern crowns take one or two visits. On the first visit we prepare the tooth and take a digital impression; on the second we bond the crown permanently. Some practices — including ours — offer single-visit crowns using in-office milling.

Expect your crown to last 10–20 years with proper care: brushing, flossing around the edges, avoiding hard foods on that tooth, and keeping up with six-monthly check-ups.
