Tooth wear-tooth loss in the elderly will cause enamel wear after long-term chewing, and even dentin wear in severe cases.
Common symptoms of tooth wear are:
1, dentin hypersensitivity. The dentin hypersensitivity areas or spots of posterior teeth mostly occur in occlusal surface, and anterior teeth mostly occur in incisal margin.
2, tooth adjacent area defect. It is often due to the wear of hard tissue in the adjacent area, or it may be broken because of the weak edge. Most of the broken edges are caused by sand in foods containing bones or rice.
3. Lateral jaw trauma. Due to the back pressure of wear, the alveolar bone on the compressed side is absorbed, which leads to tooth trauma and deformation.
Gingival atrophy-medically known as physiological tooth atrophy.
Reasons for formation:
1, some people think that it is caused by gum necrosis and shedding after gingival inflammation. Clinically, it is common to brush teeth horizontally to damage gingival tissue, leading to gingival atrophy.
2. It is related to the degree of alveolar bone absorption. The reason of alveolar bone resorption is mostly thought to be due to the lack of normal functional stimulation of periodontal tissue, which is related to the decline of chewing power in the elderly. If one tooth of the elderly can't be used for a long time or both teeth are missing, the alveolar bone will be less stimulated when eating, and the alveolar bone will be sparse easily.
3. The height of gingival attachment is closely related to the height of alveolar bone. The more alveolar bone is absorbed, the more serious gingival atrophy will be.
Root caries-the gap between the teeth of the elderly is large, which is easy to embed food, thus causing root caries.
