Parents are aware that the growth of their baby's teeth is crucial, as it not only affects their health but also has an impact on their chewing ability and appearance. So don't relax and take care of your baby's baby teeth just because they are baby teeth. Actually, it's more important to pay attention to your baby's baby teeth. How many baby teeth does a 2-year-old child have?
Firstly, babies have 20 baby teeth. Normally, most babies start to have baby teeth between 4-10 months old, and by the time they are between 2 and 2.5 years old, most baby teeth have fully grown. Generally, there are individual differences in the eruption time and overall tooth length of deciduous teeth. It is recommended that babies add complementary foods after 6 months of age. This stage is not only beneficial for exercising the gums, but also for supplementing nutrition and promoting the eruption of deciduous teeth. It is also necessary to supplement cod liver oil and sun exposure appropriately.
Secondly, the eruption of baby teeth follows a physiological pattern: eruption at a certain time, growth in a certain order, and symmetrical development of left and right teeth. The mandibular teeth of deciduous teeth sprout earlier than the maxillary teeth and form pairs, meaning that deciduous teeth with the same name on both sides grow out simultaneously. Usually, a baby will have 14-16 baby teeth when they are 1 and a half years old, and the last 4 baby teeth will be the second molars, closely following the first molars. By the time the baby is 2-2.5 years old, all 20 baby teeth have fully grown, with 10 baby teeth on each of the upper and lower jaws.
Finally, around the age of 6-12, baby teeth begin to fall out one after another and are gradually replaced by permanent teeth. There are usually 32 permanent teeth, but most people cannot grow the last four teeth during infancy. These four teeth, also known as wisdom teeth, usually begin to grow in adulthood, and some people cannot grow all of them. Therefore, the visible adult teeth range from 28 to 32.
