Many people do not take chipped or missing teeth seriously, especially when it does not involve aesthetics or does not completely affect eating. However, if the teeth are not repaired in time (i.e., dentures), it will cause the following unfavorable situations: due to the gap between the teeth, the left and right teeth will slowly move towards the gap, causing the whole row of teeth to be tilted; in a pair of teeth in opposite positions in the bite (i.e., up and down), if a gap occurs somewhere, the relative teeth will slowly move towards the gap, creating a misalignment of the bite, and over time, the normal teeth will also In time, normal teeth will become diseased. The space between teeth will gradually widen with the movement of teeth, and food residue will be easily retained in it, causing gum redness, bleeding, gingivitis, periodontitis, etc. It may also cause the occurrence and development of dental caries due to the residual bacteria, and then pulp (dental nerve) infection and necrosis, leading to pulpal periapical disease. In addition, tooth loss may also cause some subsequent problems, such as temporomandibular joint disease, due to uneven tooth force during biting and chewing movements, resulting in one high and one low tooth on both sides. Therefore, it is important to set teeth in time after tooth loss or chipped teeth.
