Crowns are full coverage restorations that are used to cover a tooth that is broken, cracked, or too deteriorated to be restored with a filling. They look and feel like your existing teeth and are most commonly done after root canal treatment, or when a large filling wears out. When a large filling is placed, the natural tooth becomes compromised and is more likely to break. Keep in mind that the jaw muscles are the strongest muscles in the human body, subjecting teeth to tremendous pressure. Crowns completely cover the weakened tooth, providing strength and protecting the tooth against breakage. Remember, it’s less expensive and restoration is easier if you place the crown before the tooth becomes cracked or broken (i.e., root canalled teeth always break eventually).
