Primary teeth (Baby Teeth) are just as important as permanent teeth (Adult Teeth). Typically, primary teeth begin to appear when the baby is between ages six months and one year. Primary teeth serve many functions, such as chewing, speaking, and holding the space in the jaw for permanent teeth. The American Dental Association advises that a dentist should examine a baby within six months after the first tooth comes in but no later than their first birthday. For a baby, the first dental visit is a healthy baby checkup for their teeth. The dentist will check for tooth decay and other problems. In addition, the dentist will be able to show you how to clean your child’s teeth properly and evaluate any adverse habits, such as thumb-sucking.
