Is it early to lose teeth at the age of 7?
Is it early to lose teeth at the age of 7? As the baby grows up day by day, the deciduous teeth will begin to "pop out" one by one. As the first set of teeth in a baby's life, deciduous teeth play a crucial role in chewing, pronunciation and appearance. So, let’s share below: Is it early for teeth to grow at the age of 7? Is it early for teeth to grow at the age of 7? 1
It is not too early to start growing teeth at the age of 7, it is a normal time.
Changing of large teeth is a normal physiological phenomenon. Most patients will experience the replacement of large teeth, which is also called the period of tooth replacement. It usually occurs around the age of 6 to 7 years old and does not usually occur. Only the big teeth will be replaced, and the other 20 teeth will also be replaced. Therefore, it is normal to start replacing the big teeth at the age of 7, and it is not too early.
When children are changing their teeth, they should eat more soft, waxy and easy-to-chew foods, such as millet porridge, eight-treasure porridge, red bean porridge and other foods. These foods will not hurt the gums and will not hurt the gums. Damage to newly erupted teeth, and during the tooth replacement period, children must develop a good habit of teething early and late to avoid bacterial infection and causing some oral diseases.
If your child’s mouth feels uncomfortable during tooth replacement, you should immediately go to a regular hospital to pass a detailed examination and actively cooperate with the doctor’s treatment plan to avoid more serious effects on the child’s body.
How many deciduous teeth are there?
When a baby is 6 months old, deciduous teeth will begin to grow. Before being replaced by permanent teeth, the deciduous teeth will grow with the baby. So how many deciduous teeth are there?
Generally speaking, there are 20 deciduous teeth, including 8 front teeth, 4 tiger teeth, and 8 back teeth. Generally, baby teeth begin to erupt when they are half a year old, and all of them appear when they are about 2 and a half years old. Between the ages of 6 and 12, deciduous teeth gradually fall out and are replaced one by one by permanent teeth.
When to replace deciduous teeth?
Babies usually start to lose teeth when they are around 6 years old, but some babies start to lose teeth as early as 4 years old, or as late as 7-8 years old. . During the teething period, your baby's deciduous teeth will gradually fall out and be replaced by permanent teeth.
Permanent teeth are the second set of teeth after the loss of deciduous teeth. If they are lost due to disease or accidental injury, there will be no replacement teeth. And the average person has between 28-32 permanent teeth.
Mothers must pay special attention to the situation of retained deciduous teeth in their babies. Retained deciduous teeth refer to deciduous teeth that have erupted but failed to fall out on time, or deciduous teeth that have not erupted but remain in the permanent dentition. The retention of deciduous teeth occupies the normal position for the eruption of permanent teeth, which may cause the permanent teeth to erupt ectopically, affecting the development of the normal occlusal relationship of the dentition. Retained deciduous teeth or residual roots can lead to plaque retention and food impaction, which will affect oral hygiene and increase the chance of dental caries in adjacent teeth.
Therefore, when the baby’s permanent teeth have erupted, the retained deciduous teeth should be removed in time. However, if the retained deciduous teeth are caused by the congenital loss of permanent teeth, they may not be treated.
What should you pay attention to when replacing deciduous teeth?
Is there a sequence for replacing deciduous teeth? Or does it vary from person to person? Regarding the sequence of replacing deciduous teeth, simply speaking, it is "a certain time, a certain order" , Left and right symmetry, first down and then up." Left and right symmetry, first down and then up are for teeth with the same name.
In addition to understanding the order of replacement of deciduous teeth, special attention must be paid to the following five issues during the period of baby tooth replacement:
1. Always pay attention to the growth of the baby's deciduous teeth and permanent teeth. According to the situation, take your baby to see the dentist regularly so that problems can be discovered at any time and solved as soon as possible.
2. Supervise your baby to brush his teeth in the morning and evening every day. It is best for adults to help brush the teeth before going to bed at night, especially the double row of teeth, which are more difficult to clean and are most likely to cause dental caries.
3. During the teething period, babies should eat more foods that are high in fiber and have a certain hardness, such as fruits, carrots, beans, corn, etc., in order to maintain a good stimulating effect on the deciduous teeth and encourage the deciduous teeth to grow on time. fall off.
4. It is necessary to promptly correct some bad habits of the baby, such as sticking out and biting the tongue, biting fingers or pencils, licking the teeth with the tongue, etc. These bad habits will affect the growth of the baby's teeth and lead to tooth deformation.
5. Strengthen the baby's calcium absorption and urge the baby to eat more foods high in calcium, such as milk, cheese, tofu, canned fish, etc., and at the same time take in enough vitamin D. Vitamins help calcium absorption. Is it too early for teeth to change at the age of 7? 2
Methods for children to straighten their teeth
1. Common methods for children to straighten their teeth
1.1. Fixed appliances: Yes Brackets, rings and other devices are fixed on the tooth surface with adhesive. The patient cannot remove them by himself, only the doctor can remove them with professional instruments. It is currently the most commonly used appliance in clinical practice with high correction efficiency. There are labial appliances and lingual appliances.
1.2. Removable appliances: attached to the teeth or mucous membranes, and can be removed and worn by the patient at will. They are generally used to correct relatively simple malocclusions in deciduous teeth and replacement teeth.
1.3. Invisible aligners: they are designed individually based on the patient’s dentition shape, simulate tooth movement through computer three-dimensional image technology, and use digital molding technology to produce multiple pairs made of elastic and transparent polymer materials. Orthodontics. Patients can remove and wear it by themselves, and the correction is almost completed without anyone noticing, without affecting daily life and social interaction. However, it is more expensive and has limited indications, so the correction of complex malocclusions and deformities cannot be completed.
1.4. Functional orthodontic device: It is mainly used for children who are still in the peak period of growth and development during the tooth replacement period or just after tooth replacement. It uses the functional force of masticatory muscles or perioral muscles to guide the growth of the jaw. Correction of mild to moderate functional and skeletal malocclusions.
Durable orthodontic treatment for children
The period of orthodontic treatment for each child is about one year, which is relatively smooth, but under special circumstances, it may take one and a half years. It can even take two years to finally complete orthodontic treatment. Children's orthodontics is a very complex project that cannot be completed in a day or two. It needs to be continuously adjusted according to the growth cycle of the children's teeth, so as to achieve the purpose of children's orthodontics and restore the normal function of the teeth.
The best time for children to correct their teeth
If the teeth are not aligned properly, it is usually between 12 and 14 years old for boys and between 11 and 13 years old for girls. Orthodontics is required at the age of 10. However, some dental and jaw deformities, such as "teething" or deformities caused by bad habits such as lip biting and thumb sucking, should be treated at the age of 3 to 5 years. During this period, the child's entire dental arch is basically fully developed, the deciduous teeth are basically replaced, the roots of the permanent teeth are gradually developed, and the occlusal relationship between the upper and lower teeth is also adjusted. The doctor can make a clear diagnosis of the type of dental deformity and take appropriate treatment. .Corrective methods.
At the same time, children and adolescents at this stage have good biological responses to external stimulation, fast bone reconstruction, high plasticity, strong tissue metabolism, short treatment cycles, good results, and easy maintenance after correction is completed.
Precautions for children during orthodontic treatment
1. Try to eat less sticky and hard food to avoid excessive collision of teeth.
2. Pay attention to cleaning the oral cavity during correction and choose a professional orthodontic toothbrush or interstitial toothbrush.
3. Teach children not to lick the appliance or artificially damage the appliance.
4. Return to the clinic once every six months or several months to let the doctor check the degree of children’s teeth correction and the degree of wear and tear of the appliance.
It is worth noting that orthodontic treatment sometimes requires tooth extraction, so when a child suffers from severe dental caries (cavities) and is accompanied by misaligned teeth, parents may wish to consult an orthodontist first. If tooth extraction is really needed for orthodontic treatment, the orthodontist will first choose to remove unhealthy teeth to avoid excessive or unnecessary treatment of dental caries. For example, if some teeth are missing due to trauma or dental caries, adjacent teeth can be used to replace the missing teeth through orthodontic treatment, thus avoiding the need for denture repair.
Harms caused by orthodontic treatment
1. Teeth become loose: During orthodontic treatment, tooth looseness increases, which is a normal reaction. To move teeth, the alveolar bone and periodontal ligament need to be reconstructed, because the teeth are fixed in the alveolar bone by the periodontal ligament, so the teeth will become loose. However, after the teeth are corrected to the normal position and stop moving, the teeth can reattach the periodontal ligament through their own repair ability and become stable, without permanent damage.
2. Impact on tooth roots: This is because during tooth correction, reconstruction activities such as absorption and proliferation are also occurring on the tooth root surface. After treatment, the tooth root returns to normal due to its own repair ability.
3. Impact on alveolar bone height: People who have undergone orthodontic treatment will have a slight decrease in alveolar bone height. This is because wearing braces makes it difficult to maintain oral hygiene and increases gum disease. The chance of inflammation will have a certain impact on the alveolar bone. After the orthodontic treatment is completed, the alveolar bone will not continue to be resorbed. If oral hygiene is maintained well, the alveolar bone will gradually return to normal.
4. Impact on the dental pulp: In the early stage of orthodontic treatment, a mild and temporary inflammatory reaction occurs in the dental pulp, which is manifested as pain or discomfort in the first few days of orthodontic treatment. However, experiments have proven that the harm of this kind of orthodontic treatment has no clinical significance. Is it early for teeth to grow at the age of 7? 3
How long does it take for a child’s teeth to grow out after they fall out?
1. It is normal for new teeth to grow out between 3 and 6 months after a child’s teeth fall out. It is normal for new teeth to grow out between 3 and 6 months after a child loses his teeth. If a child loses his deciduous teeth and does not grow back within half a year, it is normal.
2. When a child is about seven years old, the deciduous teeth will fall out and be replaced by new ones. Generally, new teeth can grow in about a month after the teeth fall out. If the child does not have teeth for a long time, it may be because the child has a little calcium. caused by missing.
3. Children’s upper teeth usually grow back in about 6 months. These are also the first two teeth to grow. If they do not appear for a long time, you can take oral iron supplements, calcium supplements and zinc supplements.
4. Children’s tooth loss is the loss of baby teeth, which is the whole process of growth and development of new teeth. Generally, growth and development will occur 3-6 months after tooth loss, and some may not grow until after 6 months. developmental.
It is recommended that children do not eat forced food during the tooth replacement period to prevent tooth root deformation and abnormal growth and development of new teeth. It is necessary to give children more food with high calcium content, such as dried shrimp skin, etc., to ensure the daily supply of milk and eggs. Calcium tablets for pregnant women can be supplemented if necessary.
What should children pay attention to when changing their teeth?
Changing teeth is a process that every child must experience. As parents, you should closely monitor the growth and development of your children's teeth so that your children can successfully go through the teething period and grow healthy and beautiful teeth.
1. Pay attention to children’s teeth changing
As children age, their deciduous teeth can no longer blend into the growing frontal bones and increasing bite force. Children's deciduous teeth begin to fall out physiologically from around 6 years old, and are replaced by new teeth by around 12 years old.
Due to the growth and development of the new tooth germ in the frontal bone and its movement towards the occlusal surface, the tissue at the roots of the children's deciduous teeth is digested and absorbed, and the children's deciduous teeth gradually loosen, eventually leading to their loss. Come down. The fallen deciduous teeth of children have no roots, and the fallen teeth look like earth-colored swallowed teeth. When children's deciduous teeth fall out, they should pay attention to observe them in order to distinguish them from rupture of the gums of the deciduous teeth.
2. Minimize damage to children
Some parents find that their children’s new teeth are loose, and thus feel restless and worried. In fact, this is caused by the fact that the gums of newly erupted teeth are not completely formed, the pulp chamber and root hole are quite large, and the cementum at the root of the tooth is too thin. At this stage, if trauma and infection occur, the gum root becomes inflamed, and the root hole cannot be closed again.
It is very inconvenient to treat. The age when children are changing their teeth is a stage where they are more active and active. It is very easy for children to have accidents such as collisions and falls while running, playing, and playing, causing maxillofacial trauma. Among them, the front teeth are also very easy to be damaged. Therefore, parents should pay more attention to preventing children from being harmed at this stage.
3. There is no need to worry about the gap between the front teeth.
Some parents find that there is a gap between the two newly erupted teeth of their children, and some even have a figure-eight shape, so they are worried about the growth of their children's teeth. Not so good. In fact, there is a certain time and sequence for the growth of new teeth. The forward central incisors (also known as teeth) erupt between the ages of 6 and 9, and the lateral incisors between the ages of 7 and 11.
Therefore, between the ages of 7 and 11, a gap will appear between the child's two teeth. As long as the lateral incised tooth erupts, the gap will naturally disappear. Occasionally, there may be a supernumerary tooth between the two teeth, causing a gap between the two teeth. This can be confirmed by x-ray examination and then the supernumerary tooth can be extracted to close the gap.
4. Tiger teeth cannot be removed
In the order of replacement of deciduous teeth, the teeth will erupt later than the first pair of canines, because when the canines erupt, the incisor area The base of the alveolar is covered with other teeth, and only the labial side protrudes. Therefore, some children's teeth often protrude to the labial side, forming tiger teeth. Some parents think the tooth is unsightly and ask the doctor to remove it, which is incorrect.
The tooth is the tooth with the most roots and the thickest teeth in the mouth. Its function of tearing food cannot be replaced by other teeth. If it is missing, the child will often be unable to chew sweets and eat. Pork ribs also affect the bite force. If correction is needed, the doctor will also achieve the purpose of correction by extracting the first or second bicuspid teeth.
5. Master the temporary malocclusion period
Finally, it is worth mentioning that during the replacement stage of primary teeth, the order of the teeth is often complicated, and sometimes even chaotic. , medically called transient malocclusion. Some parents are very worried about this and ask doctors to provide correction as soon as possible. In fact, the body's teeth have a potential tendency to be neatly arranged. When the new deciduous teeth are replaced, the tooth arrangement may be adjusted independently. Before the replacement of the new deciduous teeth is completed, there is no need to urgently correct it. It should be observed and followed up. Some children's new teeth The teeth will gradually become aligned.
Even if correction is needed, it should be carried out after the replacement of primary teeth. Generally between the ages of 13 and 15, when the eruption of permanent teeth reaches a certain height, the manufacture and wearing of dental braces can be accurate and effective.
