Babies who haven't grown teeth at 7 months or older are still considered normal. Baby teeth growth is influenced by factors such as genetics, acquired factors, and systemic diseases. It is a normal phenomenon that babies haven't grown teeth yet, and there is no need to worry too much. Parents can help their babies with some chewing exercises, which can assist in better tooth growth. Additionally, taking babies out to get some sun exposure can effectively promote calcium absorption. It is normal for babies to not have grown teeth at 7 months. Normally, babies start to grow teeth at 6 months of age. However, some babies may start earlier at 5 months, while others may be slightly later, growing teeth at 7 or 8 months, which is still considered normal. Generally, it is normal for babies to grow teeth within 10 months, but it should not be later than one year. If the first milk tooth does not erupt by one year, it is considered delayed tooth eruption. Therefore, after 8 months, if the baby still hasn't grown teeth, parents should provide some chewing exercises to help facilitate tooth eruption. Multiple factors affect baby tooth growth. The timing of baby tooth growth is influenced by many factors, including genetic predisposition, environmental factors, systemic diseases, trauma and infection, and exposure to cold. If disease factors are excluded, there is no need to worry about babies not growing teeth at 7 months. Parents should not be nervous and should not mistakenly believe that their baby lacks calcium, leading to excessive use of calcium supplements. Reasonable feeding, timely introduction of various complementary foods, as well as encouraging the baby to participate in outdoor activities and getting some sun exposure will help in the development of teeth.
