The residual roots below the gums should be extracted in time. Long-term non-extraction may lead to diseases such as periapical inflammation, periapical cysts, and apical granulomas. After extraction, implant or denture restoration can be performed to avoid affecting daily life. If the root is below the gingiva and loose, it should be extracted as soon as possible. If it is not extracted for a long time, periapical inflammation, periapical cyst, apical granuloma may occur, and even the neighboring teeth on both sides may appear to tilt toward the gap, which may cause occlusal relationship disorders. After tooth extraction will affect daily life, implant restoration, fixed or removable denture restoration can be chosen to restore the chewing and other functions of the teeth. The residual roots below the gums should be extracted in time, and it is recommended to go to a regular dental hospital for extraction and follow-up treatment.
