When does the baby start growing teeth? At what age can teeth fully grow? These are all issues that parents are very concerned about. But in daily life, parents may also find that the time for each baby to grow teeth is different. Some babies may have already grown 18 teeth by 21 months, while others of the same age only grow 16 teeth. Therefore, parents want to figure out how many teeth are considered normal for babies at 21 months. Let's talk about this issue next.
The growth of a baby's teeth is related to the calcium in their body. If the body is not deficient in calcium, the baby's tooth growth rate will be faster. If the body is deficient in calcium, the baby's tooth growth rate will be slower. Generally, when a baby reaches 21 months old, the number of teeth should be between 15 and 17, which is considered normal. If the number is less than this, the baby's tooth development will be slower. Parents should take the baby to the hospital to check whether it is due to calcium deficiency, slow tooth growth, or poor tooth germ development.
In addition to checking for trace element calcium, it is recommended that parents check their baby's bone density again and have a specialist doctor take an X-ray of their baby's teeth to carefully understand the development of their baby's alveolar bone. If the alveolar bone development is poor and leads to poor tooth germ development, active intervention treatment should be carried out, otherwise it will have a significant impact on the baby's tooth growth.
