Is it normal for a baby to have only one tooth?

Therefore, the physical characteristics shown at different stages are also different. When a child reaches a certain stage of development, he or she will grow teeth. Usually, children will start to grow teeth when they are four or five months old. Some children only grow one tooth. Is this normal? Now let’s also find out whether it is normal for a baby to have only one tooth?

There are great individual differences in the eruption of children's teeth, some earlier, some later, but for a particular child, it is all normal. For children whose teeth erupt early, the lower incisors may begin to erupt at more than 4 months old; most children begin to erupt at 6 to 8 months; and a small number of children have their teeth erupt after 1 year old, and some have their teeth erupt at nearly 1 and a half years old. But for these children, if they do not have systemic developmental abnormalities, they are normal.

Although some children's teeth start to erupt early and some start late, and although there is always a certain order for tooth eruption, not all children's teeth erupt in this order. Sometimes the order of eruption will change slightly, which is also within the normal range.

Normal babies start to grow teeth at an average age of six months, adding one tooth per month, and have six teeth at about one year old (twelve months). All twenty deciduous teeth will have grown in around the age of two and a half. However, the time when every baby grows teeth is not the same, and we often see that many babies have different teething patterns. For all the people we have come into contact with and know, it is really rare to have no teeth or incomplete teeth (except for very rare cases of so-called "congenital ectodermal dysplasia").

Therefore: Medically, growing teeth should not be a big problem. Except for a very small number of patients with a disease called "congenital ectodermal dysplasia" (this is a disease in which hair and nails also develop poorly, which is not difficult to distinguish), the order and speed of tooth growth in ordinary people may vary, but they will all grow out. The speed and order of tooth growth for each baby can be different: generally speaking, the two lower incisors start to grow first, followed by the two upper incisors, then the upper outer incisors, then the lower outer incisors, and then the canines.

However, there are also people whose canine teeth grow out first. Some people say that these people are more aggressive, but in fact this statement is not true. So theoretically, the two lower teeth you mentioned should come out together, but it is normal if only one comes out.

Many parents are always worried that their children are not developing normally. In fact, it is normal for a baby to grow one tooth. Because each child has a different physical constitution, some children develop later, so they grow teeth later. But if the child has reached the age when he can grow teeth, but has not yet grown teeth, we should analyze the cause? Take your child to the hospital for examination in time.
