It's very important to clean your mouth every day. But will rude brushing wear your teeth? Experts say that if you don't clean your mouth, you will easily suffer from dental caries, so you should pay attention to brushing your teeth sooner or later. However, incorrect brushing method can also lead to tooth damage, the most typical is the wedge-shaped defect in the neck of teeth.
In particular, the long-term use of saw type cross brushing, the junction of enamel and cementum in the neck of teeth is easy to wear, and the acid corrosion of exudates in gingival sulcus makes the teeth form a wedge-shaped defect.
Experts remind that the most important thing to prevent wedge-shaped defects is to choose the right toothbrush and master the correct brushing method---
1. The bristles of toothbrush should not be too hard, vertical brush method should be adopted, and horizontal brush method of saw type should be avoided.
2. If the tooth defect has been formed, it must be repaired as soon as possible to prevent the defect from developing and relieve the tooth pain caused by acid cold stimulation. If the defect develops and invades the pulp and causes pulpitis or periapical periodontitis, root canal therapy is needed.
"Clinically speaking, the teeth that are easy to brush a groove are premolars, canines and lateral incisors in the upper and lower jaw," experts said. "These teeth are located at the corner of the dentition, and they are subjected to the greatest force when brushing. In addition, the wedge-shaped defect of the right tooth is more severe than that of the left, and vice versa. The effect of this manipulation on the formation of a wedge-shaped defect is also illustrated.
After the teeth are brushed out of a groove, the main manifestation is dentin hypersensitivity in the early stage. When drinking cold water and inhaling cool wind, the teeth ache, and eating sweet or spicy food will also hurt. When the wear continues to penetrate into the pulp, pulpitis will be caused and tooth necrosis will occur. When the defect is deep, it can even lead to tooth fracture, which is one of the causes of tooth loss in the elderly.
