What Parents Need to Know About Baby Teeth?

Baby teeth, also known as primary or deciduous teeth, play a crucial role in a child’s overall health and development. While they may seem temporary, these tiny teeth serve essential functions in a child’s early years. Understanding the significance of baby teeth and how to care for them is vital for parents.

The Development of Baby Teeth

Baby teeth begin developing before a child is even born. In fact, tooth development starts in the womb, with the primary teeth forming during the embryonic stage. By the time a baby is born, most of the 20 primary teeth are already present, although they remain hidden beneath the gums.

Eruption Timeline

Baby teeth typically start to erupt around six months of age, although this can vary from one child to another. The first teeth to appear are usually the lower central incisors, followed by the upper central incisors, and then the lateral incisors.

Over the next few years, the rest of the baby teeth will emerge, completing the set of 20 primary teeth by around the age of three.

Good Dental Health Starts with Baby Teeth:

Ensuring good dental health for children begins with taking care of their baby teeth. Even though these teeth will eventually be replaced by adult teeth, they play a vital role in a child’s overall development.

Baby teeth assist in functions like chewing, speaking, and smiling, and they serve the crucial function of preserving space for the growth of adult teeth.

Here are some key points to remember about baby teeth:

  1. Babies are not born without teeth; they actually have 20 primary (baby) teeth that are present but not yet visible. These teeth typically start emerging (erupting) around 6 months of age.
  2. Teething, the process of baby teeth breaking through the gums, usually begins around 6 months and continues until around 3 years of age. Typically, the first teeth to emerge are the lower front teeth (incisors).
  3. Children between the ages of 6 and 12 have a mix of baby and adult teeth, as the baby teeth gradually make way for the eventual 32 adult teeth. The front baby teeth (incisors) are typically lost between 6 and 8 years old, while the back teeth (canines and molars) are not lost until ages 9 to 13.
  4. Baby teeth have thinner enamel, the protective layer covering teeth, compared to adult teeth. This makes them more susceptible to cavities and tooth decay.
  5. Having some space between baby teeth is normal and allows room for the adult teeth to emerge properly.

Your Child’s First Visit to the Dentist:

  • The first dental visit should occur within six months of the eruption of the first baby tooth or by the child’s first birthday.
  • It’s an opportunity for the child to become familiar with the dentist’s office and build trust.
  • The dentist will examine the baby’s teeth and gums and provide guidance on oral care.
  • Parents can ask questions about teething, brushing, and any concerns they may have.
  • Establishing a positive relationship with the dentist early on can reduce dental anxiety in the future.
  • Subsequent regular dental check-ups should be scheduled as recommended by the dentist.

Functions of Baby Teeth

  1. Chewing: Baby teeth are essential for chewing food properly. They help break down food into smaller pieces, making it easier for digestion.
  2. Speech Development: Properly aligned baby teeth are crucial for speech development. They enable children to articulate sounds and words correctly.
  3. Space Holders: Baby teeth serve as space holders for the adult teeth that will eventually replace them. They maintain the gaps and positions necessary for the proper alignment of permanent teeth.
  4. Aesthetic and Self-Esteem: Baby teeth also play a role in a child’s appearance and self-esteem. Problems with baby teeth can affect a child’s smile and overall self-confidence.

Dental Care for Baby Teeth

  1. Cleaning: It’s important to start oral hygiene routines even before baby teeth emerge. Use a soft, damp cloth to gently wipe your baby’s gums. Once teeth erupt, clean them with a soft-bristle toothbrush specifically designed for infants. Use water or a tiny amount of fluoride toothpaste.
  2. Avoid Sugary Drinks and Pacifiers: Avoid giving your child sugary drinks in a bottle, and never dip a pacifier in sugar or honey. Prolonged exposure to sugary liquids can lead to tooth decay.
  3. Balanced Diet: Encourage a balanced diet rich in fruits, vegetables, and dairy products to promote healthy tooth development. Limit sugary snacks and beverages.

The Transition to Permanent Teeth

Around the age of six, the first permanent molars start to emerge at the back of the mouth. These molars do not replace any baby teeth and are known as “six-year molars.” The transition from baby teeth to permanent teeth continues over several years, with the last baby tooth typically falling out around the age of twelve or thirteen.

Importance of Oral Health

Maintaining good oral health from a young age sets the foundation for a lifetime of healthy teeth and gums. Poor oral hygiene during childhood can lead to a host of problems, including cavities, gum disease, and misaligned teeth.

These issues can have long-lasting consequences that may require extensive dental treatment.


Baby teeth are more than just placeholders for permanent teeth; they serve essential functions in a child’s early years. Understanding the development, eruption, and proper care of baby teeth is crucial for parents. By establishing good oral hygiene habits early on and seeking regular dental check-ups, parents can ensure their child’s dental health and contribute to their overall well-being.

Remember, healthy baby teeth lead to healthy permanent teeth, and a lifetime of smiles.
