Although our human teeth are a small organ, they can have a great significance to our health condition. The loss of teeth can cause many adverse effects, such as: 1, chewing function is reduced or lost; 2, affect the beauty of facial shape; 3, affect the function of pronunciation; 4, have a negative impact on the remaining teeth; 5, can cause temporomandibular joint disorder; 6, affect the digestive system, resulting in malnutrition, etc. When individual teeth are missing, the chewing force is concentrated on the remaining teeth, and the chewing force exceeds the limit of the remaining teeth, resulting in periodontal edema, gum atrophy, alveolar bone resorption and tooth loosening due to the trauma caused by the remaining teeth. If there is no veneer for a long time, it may cause the adjacent teeth to tilt and shift into the gap, and the teeth corresponding to the gap will gradually elongate due to the absence of counterforce, and the occlusal relationship and tooth alignment will be disordered, resulting in the loss of the normal adjacent relationship of the remaining teeth and causing food embedding, which is also one of the causes of periodontal disease. When there are more teeth missing, the remaining teeth are tilted, shifted or elongated to the opposite side, which disturbs the occlusal relationship and hinders the jaws from reaching forward or moving from side to side. Sometimes, due to missing teeth on one side, chewing with the other side forms a partial side chewing habit, and muscle tension imbalance occurs, and the muscle will become fatigued in the long run, the condyle will move back, and the joint area will feel discomfort, and even symptoms such as pain, inability to open the mouth, and joint popping will occur, which is clinically known as temporomandibular joint disorder. Studies have shown that unilateral molar loss can accelerate learning memory loss, thus causing impairment of learning memory ability. The prevalence of tooth loss increases significantly with age. This makes the dentist awake to the fact that it is an important work of the dental workers to advocate regular oral examination and increase the publicity on the need for timely restoration after tooth loss, so as to raise people’s attention to ensuring the integrity of the dental row in the mouth, thus preventing the spread of dental diseases, avoiding the situation that the older the person is, the more teeth are missing and the worse the oral condition is, and allowing the general public to better protect the normal chewing of the mouth This allows the general public to better protect the normal chewing function of the oral cavity, maintain a beautiful face, delay the aging of the human body, improve the quality of life and maintain physical health.
