A crown is a tooth-shaped cap that covers the visible part of a damaged tooth, restoring its shape, size, strength and appearance. An onlay is a more conservative restoration that rebuilds the biting surface and one or more cusps when a filling alone would leave the tooth weakened.
Both are custom-designed in dental ceramic — most commonly e.max — and bonded into place. Done well, they're virtually indistinguishable from your natural teeth and can last well over a decade with good home care.
