When a large tooth is extracted, it is important to check exactly which tooth is in which position. If it is a wisdom tooth, there is no need to repair it after extraction as it is located at the very back and does not carry a heavier chewing function. If it is any other large tooth, it is recommended to repair it as soon as possible, as failure to do so can cause tilting of the corresponding neighboring teeth, or even problems with the entire dentition. For the repair, the choice of fixed and movable prosthesis, movable prosthesis refers to the usual removable denture, also known as removable partial denture, the advantage is easy to operate, the cost is less, but the disadvantage is that the patient needs to take off and wear every day to clean. There are also two types of fixed denture restorations: one is the fixed bridge restoration; the other is the more popular implant denture restoration.
