Primary teeth, or baby teeth, are temporary but play an essential role in a child's healthy growth and development. A baby typically begins teething at about two or three months old, with primary teeth starting to erupt after six months. The eruption process usually begins with lower teeth appearing before the uppers, starting with central incisors, lateral incisors, first molars, canines, and second molars. By the age of three, a child should have 20 primary teeth in place. These teeth are crucial for chewing food, speaking, and smiling, as well as providing space and guidance for the permanent teeth that begin to emerge around age five or six. Despite being temporary, it's vital to take good care of primary teeth to prevent decay and potential damage to underlying permanent teeth. Regular checkups and good home hygiene habits are essential for maintaining a healthy set of primary teeth, ensuring a smooth transition to a permanent set. Consulting with a doctor about caring for primary teeth and addressing any issues during their natural eruption process is recommended.
