The frequency of tooth replacement varies depending on the type of veneer. There are two main types of dental veneers: fixed and removable. Fixed denture restoration refers to the process of bonding the restoration to the abutment teeth on both sides by means of adhesives, etc. This kind of restoration cannot be freely removed by the patient and is called fixed denture. The average life expectancy is 8-10 years, and if there are no symptoms such as significant breakage or pain in the abutment teeth, there is no need for replacement. The movable denture is the process of restoring missing teeth, jawbone and surrounding soft tissues using artificial teeth and abutment material. Patients are able to take them off and wear them by themselves, and generally after 3-5 years of use, they may not fit or have poor retention and need to be re-sunk or replaced. It is recommended to maintain good oral hygiene after veneering, eat as little hard food as possible, review regularly, and seek medical attention for treatment in a timely manner if discomfort, pain, or poor retention occurs.
