According to Dr. Dale Goldschlag, of the Contemporary Dental Implant Centre, in New York City, a dental crown is a type of tooth covering which is used to cosmetically repair broken, unsightly, or partially missing teeth, or to restore stability to weakened teeth. There are several different kinds of materials that may be used in creating a crown.
• Metals, such as gold alloy, nickel, or chromium, are often the longest lasting of crown choices due to their tendency not to break, and their ability to withstand the pressure of biting or chewing.
• Porcelain-fused-to-metal crowns are cosmetically a good choice, because the porcelain can be matched to a patient’s own tooth color. However, porcelain can chip or break, and at times the metal at the base of the crown can show.
• All-resin crowns are even more prone to breakage, although they are less expensive than porcelain.
• All-porcelain or all-ceramic crowns look very natural, but are not as strong as their porcelain-fused-to-metal counterparts, and are best used for front teeth.
Dr. Dale Goldschlag is a periodontist and dental crown specialist.
As the name suggests, dental implants fill gaps left by missing teeth. They provide a foundation for replacement teeth that looks and feels natural. The implants are made of titanium, a strong material that makes for a strong foundation so that the teeth can withstand normal activities, including chewing. Implants may also preserve facial structure, which can prevent the bone deterioration that is common when teeth are missing.
The procedure is low-risk and typically takes place over two visits. The first visit is when the dental surgeon places the metal anchor into the jawbone. The anchor is given three to six months to bond with the jawbone, during which time the dentist designs the bridgework or denture and makes a new tooth. The surgeon then attaches the new tooth to the implant. The whole process typically takes six to eight months, and there is minimal disruption to the patient.
