Teeth replacement - the first milestone in baby life and this is also the time that parents need to closely keep track of the baby’s dental development.

How does the process of the teeth replacement take place?

It is normal for the children to have the teeth replacement from 6-12 years old, but there are some cases of tooth replacement sooner at the age of 4 or vice versa later at the age of 8. And the last baby teeth will be lost when children are 12 or 13 years old.

Child’s set of teeth are considered as normally developed when the order of permanent teeth will erupt like baby teeth; that means which baby tooth growing first will be lost first. Thus, parents can predict the order losing of the baby tooth as well as the order eruption of the permanent teeth. However, the tooth replacement order of the upper jaw will be little different to the lower. In the upper jaw, the common tooth order is in succession: central incisor, lateral incisor, premolars, canine and molars. In the lower, the order is central incisor, lateral incisor, canine, premolars and molars.



Time of the replacement being long or short depends on many factors such as the characteristics of each tooth type and tooth position – for example, it takes a few weeks to replace single root tooth but it takes more time for multi root tooth like molars to be removed, possibly from 1-2 months. In the same way, the replacement period of the teeth grown in good conditions is shorter than the ones stuck in the slot or blocked by the others.

In addition, some of the children’s bad habits also contribute to tooth replacement time. When milk teeth are lost, for instance, they will recognize the space in their mouth and often use hands or tongue to touch. The impact can also cause inflammation, so parents need to frequently remind children to give up these bad habits.

When should the child go to the dentist ?

The most important period possibly called the premise for the baby’s permanent teeth is when baby teeth still exists and permanent teeth have grown up. Therefore, children should be taken to the dental clinic for regular monitoring by their parents even when their teeth erupt orderly and straightly.

In particular, parents should not pull the child’s teeth out at home and by thread. Doing this is very easy to cause gum bleeding and create an open wound; in addition, putting hands into mouth will be an opportunity for bacteria to enter the wound, which can lead to infection. When teeth start to wobble, parents should take the child to dental clinic, dentist will choose the most appropriate way: either extracting or waiting until milk teeth are ready to be removed.

There are some special cases, such as baby teeth have not lost but permanent teeth have grown, the dentist will actively pull baby teeth for permanent teeth to grow into proper position. Or case of permanent teeth eruption without space is able to cause malocclusion or crowding, the dentist will pull earlier or grind the edges of the adjacent baby teeth. This creates enough room for permanent teeth to grow rightly into.



During this period, some children still keep bad habits such as: thumb sucking, tongue thrusting, teeth grinding, mouth breathing, lips sucking, chin cupping… These habits will cause buckteeth, uneven teeth, crowded teeth or spaced teeth, or the upper teeth do not fit the lower. Unless getting promptly treatment, children will not have beautiful mouth and pretty smile.

Unfortunately, if your kids encounter the dental problems, you should not worry so much. Because in this stage the face and jaw have not fully developed yet, it is advantageous for appliance to expand and rearrange teeth. The instruments were thoroughly researched and designed to ensure that children do not feel much uncomfortable and they can eat normally.

During the replacement period, the children should avoid :

Always closely monitor the tooth replacement process prevents children from the chewing gum, sweet, hard-chewing food. If the tooth eruption makes children painful, parents should feed children with soft foods such as rice gruel, soup or fruit juice. Children should be advised to avoid touching by hand and pushing his/her tongue into space of being-replaced teeth, as well as teach children how to carefully look after the new growing teeth and do not forget the oral hygiene after each meal.

As a child growing up, mom and dad should not only bring children up but also pay special attention to their stage of teeth replacement. Only doing this help our children have even teeth and beautiful smiles.
