Crestwood Dental Group in St. Louis, Missouri, provides patients with long-lasting porcelain and zirconia composite dental crowns to safeguard and repair their teeth. Dr. James Maxwell and the Crestwood Dental Group staff may propose a porcelain or zirconia dental crown when a patient's tooth has considerable decay, has had a root canal, is chipped or cracked. A dental crown is a protective cap that is personalized and then put over the injured tooth. Our crowns are made from a model of the patient's tooth and are molded and colored to resemble the natural teeth around it. This guarantees that your dental crown blends in with the rest of your teeth.
