Baby tooth extraction is a problem that many parents are concerned about during the period of baby teeth replacement. So, how long does it take for a baby tooth to grow back and how long does it take for a baby's teeth to grow?
1. How long does it take for baby teeth to grow back?
Usually, 6 years old will be the time to start replacing baby teeth with permanent teeth and until 12 years old is when the jaw arch is relatively full of permanent teeth.
At the time of tooth replacement, the baby teeth will be loose and fall out, and then the permanent teeth will erupt. Depending on the location of each child, the time to erupt permanent teeth after the baby teeth fall out will vary, but will usually range from 1-2 months and girls will grow faster than boys.
The sequence of baby teeth loss and replacement by permanent teeth in the order and age is as follows:
The first tooth to be replaced by permanent teeth is the primary incisor at the age of 6 to 8 years. After a period of 2-4 weeks, the permanent incisors will erupt. When children reach 10-12 years old, baby canines fall out and permanent teeth grow in the next 2-4 weeks. Premolars begin to be replaced by permanent teeth when the child is 9-11 years old and 1-2 months later, the time when the permanent teeth come in. The last molars are replaced at the age of 10-12 years. The number of roots also contributes greatly to the time it takes for permanent teeth to erupt after baby teeth fall out. Incisors and baby canines have only one root, so it only takes 2-4 weeks to change. Meanwhile, molars with many roots need about 1-2 months.
On the other hand, there are also some teething conditions that affect the time to replace baby teeth in children, for example, when baby teeth fall out, leaving a large gap, they will grow faster than crowded, pinched teeth. . In particular, common bad habits in children such as pushing teeth, biting pens also contribute to determining the time of permanent teeth eruption.
2. The cause of the tooth extraction takes a long time to grow
Teeth grow slowly due to many causes, including:
Underground teeth, misaligned: These teeth do not grow straight up in the space left by baby teeth on the jaw but tend to grow. The direction of the eruption hits the adjacent teeth, so the eruption time will be longer. Gum fibrosis: This condition makes it difficult for the teeth to come out because the gum layer on the teeth has thickened. Missing tooth germ: Missing tooth germ can be congenital during embryogenesis or tooth germ has been damaged when the child is accidentally bumped. Lack of nutrition: When children are not provided with the necessary nutrients, it will make the time to replace baby teeth in children is prolonged, especially the amount of calcium provided to the teeth. Children often practice bad habits: Habits such as tongue thrusting, thumb sucking, teeth grinding, bottle feeding will also cause children's teeth to grow slowly. 3. What are the consequences of a tooth extraction that takes a long time to grow? Cases of baby teeth that have been lost for a long time but the permanent teeth have not come in can be a potential risk of causing damage to the child's teeth. If the normal tooth replacement time is exceeded, it can lead to some of the following complications:
Teeth that grow underground, grow misaligned leading to slow growth for a long time, which can damage the adjacent teeth and gums, leading to pus swelling, swollen cheeks. When teeth are lost for too long, it will reduce the force exerted on the jawbone at the site of tooth loss, causing bone loss. At that time, the child's jawline will be smaller, causing protrusion, underbite, ... even causing inflammation of the jawbone. The space left on the teeth for a long time waiting for the permanent teeth to erupt can cause the adjacent teeth to grow out of position. Meanwhile, other teeth on the jaw will also tend to lean towards the gap, which will cause the teeth to be misaligned and crooked.
4. What should parents do when their child's teeth are slow?
Build a full menu to provide nutrients for children such as vitamins A, B, D, calcium, zinc, magnesium,... Foods containing many of these nutrients need to be supplemented for children throughout. developmental stage, especially the time when baby teeth are replaced. Children should limit eating foods containing a lot of starch such as sweets, coca, ... as well as foods and drinks that are too hot or too cold so as not to delay the teething process of children. Instruct children to properly clean their teeth at least twice a day and after eating. Remind children to eliminate bad habits such as tongue thrusting, thumb sucking. The child has regular dental check-ups every 3-6 months so that the doctor can monitor the child's teeth replacement process to ensure normal teeth development. In general, depending on the location of each child, the time to erupt permanent teeth after the baby teeth fall out will vary, but will usually range from 1-2 months and girls will grow faster than boys.
