Over time teeth begin to weaken and become more susceptible to problems such as decay, cracks, discoloration and other problems. If you are self conscious about your smile because of cracked, broken, decayed or worn teeth, crowns can restore or create a healthy, natural looking smile. If we notice that a tooth is weakened by a large filling, is cracked, or has a large fracture, a crown may be the best course of treatment to prevent additional problems in the future. Crowns function like natural teeth and are designed to protect your teeth from further damage.
