A filling repairs a smaller part of a tooth. A crown is different because it covers and protects more of the tooth when the remaining structure is weak.
Common signs we check
We look at cracks, large old fillings, root canal treated teeth, bite pressure and whether the tooth is likely to keep breaking with another filling.

Why timing depends on the case
Some teeth can be restored quickly, while others need gum, bite or root health reviewed first. The right timing depends on what we find during the consultation.
