…are full coverage restorations that are used to cover a tooth that is likely to break, or is too broken down to be restored with a filling. They are most commonly done after root canal treatment, or when a large filling wears out. Teeth are subjected to tremendous pressures. Crowns ride over the weakened tooth, providing strength & protecting the tooth against breakage. A broken or cracked tooth is a far more serious matter & much more difficult to treat. Crowns prevent this, as well as making for a nice smile.
