Milk teeth have 20 siblings and start growing long before your baby is even born. Normally you can’t see them when your baby is born because they are still sleeping inside the teether. However, there are some special cases where individual milk teeth have erupted at birth (birth teeth). These milk teeth may fall out because the roots are not well developed and may interfere with breastfeeding. In the baby 6-8 months of age below the middle two milk teeth teeth will slowly wake up and gradually drilled out of the gums, this time the baby may be because of the gums itchy begin to like to bite things, spit bubbles. Mothers and fathers at this time, or even earlier should be for the baby oral care. You can buy a special kind of finger cushion to the baby “brushing”, the baby will show very enjoyable. When the baby teeth are just coming out, they may not be very neat, a little “crooked” is acceptable, with the slow growth of the milk teeth later, usually can be adjusted by themselves. As the baby teeth come in, they can usually be adjusted on their own. It is rare for crowding to occur during the baby teeth period. On the contrary, with the growth of the jawbone, gaps may appear between the milk teeth, and these gaps play an important role in the alignment of the teeth after replacement. Li Tao, Department of Oral and Maxillofacial Surgery, Stomatological Hospital of Shandong University Comparatively speaking, milk teeth accompany babies for a relatively short period of time, and gradually fall off with the eruption of permanent teeth at the age of about 6 years. But don’t think that they have to be replaced sooner or later and don’t pay attention to the maintenance of the health of milk teeth. For a long time, babies will need their milk teeth to cut, bite, and grind food to get the nutrients necessary for growth and development. Like adults, for many babies who love to look good, a mouthful of bad teeth may affect their ability to “socialize” with other children, which will ultimately affect the baby’s psychological health and development to a large extent. Early loss of milk teeth may cause permanent teeth to move forward during eruption, resulting in crowding and poor bite relationships. Of course, babies do not pay attention to the care of their milk teeth on their own, and parents should take on the role of their baby’s “personal dentist” in this process. Before the baby learns to brush, you can use clean gauze to wrap your own index finger in clean water to help your baby clean his or her mouth, and this process may continue until the baby is about two and a half years old. When your baby reaches the age of two and a half, you can take advantage of his curiosity and gradually guide your baby to learn how to brush his own teeth. You can use a soft-bristled toothbrush and fluoride toothpaste for your baby, but be sure to watch your baby to avoid swallowing the toothpaste by mistake and causing damage. The most important thing is to brush the teeth before going to bed, after brushing the teeth, do not give the baby to eat, otherwise the previous work will be in vain, especially do not let the baby get into the habit of sleeping with a bottle.
