Primary & Permanent Teeth
Primary teeth are important for several reasons. Foremost, good teeth allow a child to eat and maintain good nutrition. Healthy teeth allow for clear pronunciation and speech habits. The self-image that healthy teeth give a child is immeasurable. Primary teeth also guide eruption of the permanent teeth.
Permanent teeth begin eruption around age 6, starting with the first molars and lower central incisors. This process continues until around age 21. Adults have 32 secondary (permanent) teeth including the third molars (wisdom teeth).
