Infants are often referred to as children up to one year old. During this period, most infants will develop teeth within 4 to 10 months, and individual children will develop teeth around one year of age. If teeth have not developed beyond one year of age, it is necessary to go to the hospital for a checkup.
The teeth that grow during infancy are called baby teeth. Since the growth and development of each infant is different, the exact time of eruption of baby teeth may also be different. Generally speaking, most infants will have their first baby teeth at 4 to 10 months of age, and individual infants will have their first baby teeth at around one year of age.
If a baby is over one year old and has not yet developed teeth, it is important to consider the problem of late eruption of milk teeth, and need to go to the pediatric department of the hospital in a timely manner for consultation. Delayed tooth eruption is associated with calcium and vitamin D deficiencies, hypothyroidism, and other causes, which should be treated as soon as they are diagnosed.
