Dental Anatomy and Tooth Eruption Charts

Primary Teeth

At Pinellas Pediatric Dentistry, we understand that each child's dental development is unique. The eruption of primary or baby teeth varies among children, and this natural process should not cause concern for parents. Here's what you need to know about primary teeth:

Timing of Eruption

Children's primary teeth typically start with the lower central incisors around six months of age and conclude with the second molars at approximately two years old. It's normal for eruption times to vary, and girls often experience earlier eruptions than boys. Lower teeth generally appear before their upper counterparts.

Importance of Primary Teeth

Primary teeth play crucial roles beyond just chewing:

  • They are essential for proper nutrition and chewing, aiding in the digestion of food.
  • They contribute to the development of clear speech patterns.
  • They act as placeholders, ensuring proper spacing for the permanent teeth that will begin to emerge around age six.

At Pinellas Pediatric Dentistry, we're here to support your child's dental health journey. Our team provides personalized care and guidance to help ensure your child's teeth develop healthily and function properly.

Permanent Teeth

At Pinellas Pediatric Dentistry, we provide comprehensive care for children's dental development, including the transition to permanent teeth. Here's what you should know about adult teeth:

Adult Mouth Composition

A fully developed adult mouth typically contains 32 teeth, including wisdom teeth. These permanent teeth generally follow a similar eruption sequence as baby teeth. Early eruption of primary teeth often indicates early eruption of permanent teeth as well, and vice versa.

Timing of Eruption

Permanent teeth typically begin to emerge between ages 6 and 8 years old. This process is crucial for establishing a healthy dental foundation that can last a lifetime with proper care.

Importance of Dental Care

Well-maintained permanent teeth are designed to endure a lifetime with proper oral hygiene and regular dental check-ups. By instilling good dental habits early, we can help ensure your child's permanent teeth remain healthy and strong.
