If half of a large tooth is lost, it is definitely possible to fill it from a dentistry point of view, but it depends on the exact size of the loss, the nerve situation and the condition of the remaining tooth. If there is not a lot of tooth loss and a relatively stable resistance and retention shape can still be achieved, filling treatment can be considered at this time, that is, filling. If there is a lot of loss, there are other options, such as inlays or high inlays, direct crown restorations or pile crown restorations, which are all ways to restore the tooth loss. In conclusion, there are a variety of clinical restorations for larger defects in the dentition. It is recommended to visit the nearest dentistry department for a specific review and selection of an adapted restoration method.
