There are many reasons, mainly including genetic factors and environmental factors.
Environmental factors include congenital factors and acquired factors.
Congenital factors refer to the various influences on the growth and development of the fetus in the mother's womb, which may be the imbalance of nutrition and metabolism of the mother or fetus, the mother's rubella or virus infection, the mother's injury during pregnancy or the birth injury caused by childbirth.
Acquired factors point out the influence on growth and development after birth. (1) Diseases: Some acute infectious diseases and some chronic wasting diseases may affect the development of teeth and jaws. Endocrine dysfunction or malnutrition, especially vitamin deficiency, may affect the development of teeth and jaws. (2) Abnormal respiratory and swallowing functions may affect the development of teeth and jaws. (3) Bad habits such as biting your fingers, biting your upper or lower lip, sticking out your tongue or sticking out your tongue. (4) problems with deciduous teeth or tooth replacement. Including premature deciduous teeth, delayed deciduous teeth, premature deciduous teeth, and disorder of eruption order of permanent teeth. , will cause uneven teeth.
2. Is there any harm in irregular teeth?
First: affect the beauty of the face.
Second: Uneven teeth can easily lead to unclean brushing, so it is easy to grow dental caries and tartar, which will affect the health of teeth and periodontal.
Third: because the relationship between upper and lower occlusion is not good, it will affect eating, reduce chewing function, increase gastrointestinal burden, and thus affect health.
Fourth: Sometimes it will affect pronunciation.
Fifth, some children are laughed at by classmates or friends because of their ugly teeth, which makes them feel inferior and affects their mental health.
So your irregular teeth have so much harm. I hope that all parents of children can pay attention to their children's teeth, check them regularly, give them a pair of neat, beautiful and healthy teeth, and give them confidence at the same time.
3. Is there any way to treat irregular teeth?
Irregular teeth can be corrected. Many people think that their parents gave them such long teeth and they can't change them. With the development of the times, this old concept should be changed. Orthodontics is also a discipline called orthodontics. It has a history of 100 years.
4. Can only teenagers correct their teeth? Can adults correct mistakes?
Adults can do orthodontics just like teenagers and children. So if you believe in science, you also have the right to pursue beauty.
5. Do you want to correct your child's tooth changing period?
Children generally do not need correction when changing their teeth, except in the following cases.
(1) Severe skeletal deformities of maxilla or mandible, such as excessive protrusion of front teeth and lips? Quot sweetheart
(2) Bad habits seriously affect the development of teeth and jaws. For example, the habit of biting your lower lip, eating your fingers, breathing through your mouth and sticking out your tongue.
(3) Severe dislocation of individual teeth, such as twisted teeth; Individual teeth are malocclusion (the upper teeth bite inside the lower teeth).
There will be some temporary malocclusion when changing teeth. These conditions include: slight crowding, gap in front teeth and deep occlusion. Parents don't worry when they see this. As children grow up, these mismatches will gradually disappear or ease, so there is no need to correct them.
6. When is the best time for correction?
Generally speaking, girls have the best correction when they are 10- 12 years old, and boys have the best correction when they are 1 1- 13 years old. At this time, the deciduous teeth have just been changed.
However, for children with skeletal deformities, especially those who "pick their teeth", doctors suggest that they should correct them as soon as possible when changing their teeth. Early correction is helpful to use the peak period of children's growth and development to block the abnormal growth and development trend and guide them to normal.
7. What are the methods of correction?
Movable appliance: it is generally used to correct simple mistakes and deformities of deciduous teeth and dentition, or to correct them with fixed appliances. The patient can take it down by himself.
Fixed chair orthosis: the most commonly used orthosis. The patient can't take it off himself.
Functional chair appliance: it is mainly used for children who are still at the peak of growth and development during or just after tooth replacement. The functional appliance can correct skeletal malocclusion and deformity.
Orthognathic surgery: Serious dentofacial deformities, such as maxillary protrusion, maxillary retraction, mandibular protrusion and mandibular retraction, need to be corrected by surgery and orthodontics if simple correction cannot be solved.
8. How long does it take to correct the teeth?
General correction takes about one and a half to two years. Generally, children are faster than adults, and tooth extraction treatment takes longer than no tooth extraction treatment. Complex mistakes and deformities take longer to treat than simple ones. The correction time of skeletal deformity is longer than that of simple tooth deformity. Everyone's situation is different, and it is necessary to analyze the specific situation and the treatment time. After the correction is completed, it is generally necessary to wear the retainer for about one and a half years.
9. Does orthodontics lead to loose teeth? Will you lose your teeth when you get older?
During orthodontics, the teeth will loosen slightly during movement, but after a period of maintenance, the alveolar bone around the teeth will be rebuilt and the teeth will become as stable as before. So don't worry about losing your teeth when you get old.
10. Why do you need tooth extraction?
About 50% of orthodontic patients need tooth extraction.
The purpose of tooth extraction is:
(1) Arrange the crowded teeth by using the extraction gap. Patients with crowding degree II-III are more likely to have their teeth extracted.
(2) Retract the anterior teeth between tooth extraction, improve the protrusion of dental arch and improve the face shape. For example, some people have protruding lips. After tooth extraction, the protrusion of lips will become smaller and the face will become beautiful.
(3) The occlusal relationship of the posterior teeth is adjusted by the extraction interval, so that the posterior teeth are staggered and the occlusal contact area is the largest, and the best chewing efficiency is achieved.
1 1, does it hurt to correct teeth?
Generally, you will feel some pain and chewing weakness within 3-6 days after wearing the fixed appliance and each follow-up visit. You can eat soft food these days. Generally, the pain will be gradually relieved until it disappears.
12. What checks are needed to correct it?
Before calibration, the following checks are usually required:
(1) Tooth impression: (that is, taking the mold) is used for doctors to diagnose whether the design is right or wrong, and make a comparative examination in the future treatment process.
(2) Photographing: Before treatment, the doctor should routinely take photos of the patient's face and occlusion for comparison with the end of treatment in the future.
(3) X-ray examination: Each patient routinely took lateral cephalograms and panoramic radiographs.
(4) Formulation of treatment plan: The doctor calculates the types of malocclusion according to the model, photos and X-rays, and formulates a detailed treatment plan. Then the doctor explained the treatment plan to the patients and their families and asked for their opinions. After the treatment plan is determined, the patient or the patient's family will sign the consent form.
(5) Specific treatment process.
(6) After the treatment, remove the appliance and put on the retainer.
13. Can tooth dislocation with periodontal disease be corrected?
Many patients with periodontal disease often find that their teeth are slowly dislocated, and there is a gap between the front teeth, which is getting bigger and bigger, seriously affecting the facial beauty, and many patients are very upset. In fact, this situation can be solved by corrective measures. After systematic periodontal treatment, periodontitis can be controlled, and patients can master their own methods of maintaining oral hygiene, so they can wear fixed appliances for treatment.
Generally, after orthodontic treatment with periodontal disease, it is necessary to stick a fixed retainer wire on the lingual side of the tooth to permanently maintain the position of the tooth and also play a role in maintaining periodontal health.
14. Why do you still need to wear retainers after correction?
After the correction is completed, the teeth become neat and beautiful by removing the appliance, but this is only half of the Long March. Next, you must put on the retainer. Because the teeth are still unstable in the new position at this time, it takes a year and a half to keep the new tooth position with the help of retainers and wait for alveolar bone reconstruction.
There are two kinds of retainers: movable and fixed. Fixed retainers, also known as permanent retainers, are usually used for adult patients.
15. Is there anything that looks more beautiful?
Many adults want to straighten their teeth very much, but they are worried about "steel mouth and iron teeth" after wearing orthodontic appliances. For aesthetic reasons, people invented transparent brackets and lingual appliances. Transparent brackets are similar in color to teeth, so they are not obvious. The lingual appliance sticks the bracket to the inside of the tooth close to the tongue, so it can't be seen from the outside.
