It is a very normal clinical condition for babies to start teething at 6 months. Most children generally begin to grow their first teeth around 4 months to 8 months of age. Of course some children develop early and their teeth erupt earlier and some children develop later and their teeth erupt later, but 6 months is a relatively very common time point. It is generally considered normal for a child’s first tooth to begin erupting before the age of 1 year. Of course, this is provided that the erupted tooth is in a normal position and is very strong, with no damage to the dentition. Generally, the first tooth to erupt is the lower jaw central incisor, which is the middlemost tooth below, and then the upper jaw incisors begin to erupt. Generally, the order of eruption of teeth is from the middle to the sides. The newly erupted teeth should be cleaned as soon as possible. It is generally recommended that children drink some water after eating, and parents can wipe the newly erupted teeth and surrounding gums with a soft clean gauze dipped in warm water to maintain the oral hygiene of the child.
