Humans develop two sets of teeth: primary teeth (also known as “baby teeth”) and permanent adult teeth. Primary teeth are temporary and play a role in a child’s early development before being replaced by permanent teeth.
The Count and Role of Primary Teeth
Children have 20 primary teeth, 10 in the upper jaw and 10 in the lower. These teeth are important for several functions beyond chewing food. They aid in speech development by helping children form sounds and words clearly. The ability to bite and chew food properly also supports good nutrition and digestion.
Primary teeth also serve as “space holders” for the permanent teeth developing beneath the gums. They help guide permanent teeth into their correct positions and influence the proper development of the jaw and facial muscles.
From First Tooth to Tooth Fairy
A child’s first primary tooth typically erupts around 6 months of age, though this can vary. The lower central incisors are often the first to appear. The process of all 20 primary teeth emerging usually continues until a child is about 2 to 3 years old.
As a child grows, their primary teeth begin to loosen and fall out, making room for the permanent teeth. This shedding process generally starts around age 6. The lower central incisors are commonly the first primary teeth to be lost. The replacement of primary teeth by permanent ones continues gradually, typically concluding by age 10 to 12 years.
Why Primary Teeth Need Care
Despite their temporary nature, primary teeth require consistent care. Neglecting these teeth can lead to pain and infections, which can cause discomfort for a child. Tooth decay in primary teeth can also make eating difficult, potentially affecting a child’s nutrition and overall well-being.
The early loss of primary teeth due to decay or injury can lead to complications for the permanent teeth. If a primary tooth is lost prematurely, neighboring teeth may shift into the empty space, leaving insufficient room for the permanent tooth to erupt correctly. This shifting can result in crowded or misaligned permanent teeth, which may require orthodontic intervention later. Establishing good oral hygiene habits early sets a foundation for lifelong dental health.
