Crown vs filling

A filling repairs a small to moderate cavity. A crown covers and protects a tooth that’s too damaged, cracked or weakened (often after a root canal) for a filling to hold.

You’ll usually need a crown if

  • More than about half the tooth is damaged or missing.
  • The tooth is cracked.
  • You’ve had a root canal on a back tooth.
  • An old, very large filling keeps failing.

Middle ground: inlays and onlays

For damage too big for a filling but not bad enough for a crown, an inlay or onlay saves more natural tooth.

Prices: filling cost, crown cost.

Frequently asked questions

Can I get a filling instead of a crown to save money?

Sometimes, for moderate damage, but a large filling in a weak tooth can crack. Ask your dentist about the risk and about onlays.
