Loose teeth in the elderly may be caused by trauma, occlusal trauma, gum recession, etc. They can be treated by tooth fixation, adjusting the occlusion, and extracting and installing a denture. 1. Trauma: The teeth of the elderly may become loose under the effect of trauma, and need to be reset, and then the teeth are fixed by sutures, arch splints and other materials. 2. Occlusal trauma: Incorrect biting style may lead to loose teeth, which need to be adjusted under the guidance of professional dentists to alleviate the loosening of teeth. 3. Gum recession: Gum recession occurs in the elderly due to ageing. When loose teeth have no retention value under the physician’s assessment, the affected teeth can be extracted and a denture can be installed. Elderly people can go to the hospital in time after the loose teeth, under the guidance of the physician to carry out the relevant treatment.
