What should I do if my teeth are uneven?

What should healthy teeth look like? A: Healthy teeth generally meet the following standards: First, there are no oral diseases such as tooth decay and periodontitis; Second, the appearance and color of teeth are normal; Third, the teeth are arranged neatly; Fourth, the occlusal relationship between the upper and lower teeth is normal, which can be considered as healthy and beautiful teeth. What needs to be emphasized here is the occlusal relationship between the upper and lower teeth, that is, the cusp-socket embedding relationship between the upper and lower teeth, because this is often ignored by patients. In fact, the mosaic relationship between teeth has the most direct influence on the movement of the jaw in human chewing, and then affects the normal growth and development of the jaw. Causes and prevention of uneven teeth? A: There are two main reasons for the irregular arrangement of teeth. On the one hand, it is congenital genetic factors. Parents or immediate family members have irregular teeth or abnormal jaws, and children are prone to similar problems. On the other hand, due to the influence of acquired environment, there are some abnormalities in tooth replacement, such as premature shedding or retention of deciduous teeth due to caries, which leads to abnormal eruption of hereditary permanent teeth, and some bad habits such as biting lips and licking fingers can also cause and aggravate tooth irregularity. If the acquired causes of tooth irregularity are found in time, intervention and prevention can be carried out. Therefore, since children (6-7 years old) begin to change their teeth, parents are advised to find an orthodontist for regular check-up, early detection and early treatment. It should be emphasized that the whole dentition replacement process takes a long time and varies greatly among individuals. In some cases, even oral general practitioners can't accurately grasp the treatment opportunity. If conditions permit, it is recommended to find an orthodontist for examination, so as not to delay the best treatment opportunity. What harm does uneven teeth have? Answer: The harm of irregular tooth arrangement is first of all the beauty and psychology of patients. Some children will be depressed because of their ugly teeth, unwilling to associate with others and afraid to grin. Secondly, it is functional influence. Some serious tooth irregularity or malocclusion will affect the chewing efficiency of patients, affect the digestion and absorption of food, and increase the burden of gastrointestinal tract. Some cases of uneven teeth will also affect the self-cleaning function of teeth. Teeth themselves have the function of self-cleaning, and healthy teeth have the function of cleaning the tooth surface when chewing food. Irregular tooth arrangement will also affect brushing, and many places can't brush, which is easy to cause gingivitis. If it develops, it may lead to periodontitis and tooth decay. In addition, some occlusal abnormalities are the main causes of temporomandibular joint diseases. First, the position and arrangement of teeth are abnormal, such as uneven arrangement of teeth, going in and out, or obvious gaps between teeth. Secondly, the abnormal occlusion of upper and lower teeth and the soft tissue problems of lips caused by it, such as lip process, lip opening and tooth exposure. Third, the maxillary and mandibular abnormalities caused by severe tooth winding and mandibular retraction. Can adults still correct it? There is no age limit for orthodontics? A: There is no age limit for orthodontics. Even a 60-year-old patient can receive orthodontics as long as his teeth are healthy. The dental health condition mentioned here mainly refers to the health condition of periodontal tissue of teeth. As long as the teeth are not obviously loose and the gums are not shrinking too much, they can be corrected. In fact, at present, nearly 50% of all patients have been treated by adult correction. What kind of instruments? A: At present, there are three commonly used orthodontic techniques in the world: 1. Lip-side orthodontic technique, in which brackets (appliances) are bonded to the outside of teeth and teeth are aligned by replacing archwires, is also the most common kind of "braces". Commonly used labial brackets are mainly divided into traditional straight wire brackets and self-locking brackets according to design. At present, in developed countries in Europe and America, self-locking bracket has gradually become the mainstream because of its advantages of simple operation, more comfort for patients and fast alignment speed. According to the manufacturing materials, brackets can be divided into metal brackets and ceramic brackets. The main difference between them lies in the appearance and color of brackets, mainly considering the aesthetic needs of adult patients. 2. Lingual orthodontics, in which brackets are bonded to the inner side of teeth (lingual side), and teeth are aligned by replacing archwires. Lingual orthodontics first appeared in the United States and Japan, with a history of 30 years. Through the unremitting efforts of several generations of doctors, it has become a routine treatment technology in Japan, South Korea and developed countries in Europe and America. The curative effect of lingual correction technology can be comparable to that of labial correction technology, and the indications are greatly increased. Because lingual orthodontics requires more doctors' skills and operation time beside the chair, the treatment cost is 2~3 times higher than labial orthodontics. At present, corrective techniques are mainly suitable for adult patients with high aesthetic requirements. 3. Bracket-free orthodontic technology, through wearing and replacing different transparent plastic appliances, can achieve the purpose of correcting teeth. Bracket-free orthodontics simulates tooth movement by computer three-dimensional technology, and patients realize tooth three-dimensional movement by replacing a series of transparent plastic appliances. Beauty and comfort are the outstanding advantages of this technique, but plastic appliances have their limitations in controlling teeth, so this technique is mainly used for the treatment of non-extraction patients at present. First of all, you should pay attention to your diet. You shouldn't bite hard food, such as bones and nuts. Biting these particularly hard foods is easy to damage the utensils and will have an impact. Try to avoid eating too hard and sticky food. Change your way of eating. Don't chew with your front teeth. When eating apples and other fruits, you can cut the apples into small pieces and bite them with your back teeth. Finally, chew slowly and slowly, and the possibility of appliance damage is much smaller. Second, brush your teeth well. It is very important to maintain oral hygiene after wearing braces. If you are not careful, food scraps will stay around the braces and between the teeth. If it is not cleaned in time, it is easy to get dental caries and gingivitis. It is recommended to brush your teeth in time after each meal and try not to drink or drink carbonated drinks. In addition, the method of brushing teeth after wearing braces is not the same as usual. Brush your teeth vertically along the long axis of your teeth when you don't wear braces. After wearing braces, you can't brush vertically. At this time, use a toothbrush with small brush head and soft bristles to clean the tooth surface and gum edge around the braces and brush them carefully. The toothbrush should be changed frequently, and it is best to change a toothbrush every month or two during the correction period. If individual teeth are really difficult to clean, you can also use a gap brush with a particularly thin brush head for cleaning. Does orthodontics have any side effects? A: Modern fixed orthodontics has a history of over 100 years and has been proved to be a mature and perfect technology. At present, there is no scientific evidence that perfect orthodontics will bring side effects to patients. Patients often worry that their teeth will fall off early after orthodontic treatment. At present, studies have confirmed that tooth loss in the elderly is caused by periodontitis and has nothing to do with orthodontic treatment. As for whether tooth extraction treatment will affect children's memory and intelligence, it is a misunderstanding. There will be some problems after orthodontics in clinic. Demineralization of teeth: Chalk color changes around brackets or gingival margin during orthodontic treatment, which are due to the patient's careless brushing during treatment, failure to maintain good oral hygiene, and changes in tooth color and substance caused by bacteria in soft dirt on tooth surface. Tooth demineralization is more common in adolescent patients with poor coordination. At present, prevention is mainly done through oral hygiene education, and the chalky color change that has occurred can be improved through repair. 2. food impaction: many people will have the experience of food impaction. Many food impactions are caused by aging and atrophy of gums, which is a normal aging change. But some cases of food impaction after orthodontics can be avoided. These food impactions are often because orthodontists only pay attention to the arrangement of the front teeth, but do not treat the abnormal arrangement and abutment of the teeth, or they are still scattered in the gap after treatment. This treatment is not perfect.
