When you need one
A crown suits a cracked tooth, a tooth with a large filling, a tooth after a root canal, or an implant. A bridge suits a gap when the teeth on each side need crowns anyway.
Visits and care
A crown usually takes two visits: one to shape and scan the tooth, one to fit the porcelain. Brush and floss as usual; under a bridge, use a floss threader or a small brush.
Questions about crowns and bridges
How long does a crown last?
With good care a crown can last many years. Grinding, gum disease and decay at its edge shorten that, so keep your checkups.
Does insurance pay for crowns?
Many plans pay part of a crown when it repairs a damaged tooth. We check your plan and give you the numbers in writing first.
