Denture Dentist Elmhurst NY, Dr. Alexandra Khaimov, speaks about the options available to replacing missing teeth. The first and most efficient option to replacing missing teeth is dental implants. Dental implants are long lasting tooth root replacements that oral surgeons implant into the jawbone to simulate the root of a pre-existing tooth. Unlike dentures or bridges, dental implants don't move or shift and they can last a lifetime. Dental crowns are the second option available to replacing missing teeth. A dental crown is a tooth shaped cap that is placed over the tooth to restore its shape and size, strength, and improve its appearance. Dental bridges are the third option available to replacing missing teeth. A dental bridge is a type of crown that is used to fill an empty space between two teeth, which usually occurs after a tooth has been extracted.
