Milk teeth are too close together and permanent teeth can grow in. Early baby teeth will usually be more tightly packed, but with age, the baby’s jawbone will gradually develop, the gap between the teeth will gradually increase, generally does not affect the subsequent eruption of permanent teeth, teeth can grow neatly, so do not worry too much about the early growth of milk teeth too dense. If in the late development of milk teeth, the teeth are still tight, you can continue to observe, because in the development of children during the period of jaw growth will exceed the speed of tooth replacement, permanent teeth can still erupt normally and can grow neatly. If the eruption of permanent teeth is hindered, it is necessary to use orthodontic appliances to promote the development of jawbone and ensure the normal eruption of permanent teeth. Parents do not need to worry too much when the milk teeth are too dense, but should pay attention to the protection of milk teeth, maintain oral hygiene, so as not to affect the development of permanent teeth.
