How Many Teeth Do Children Have?

Children typically have 20 primary teeth, also known as baby teeth, which start coming in around the age of six months. These baby teeth play a crucial role in your child’s ability to chew, speak, and guide the permanent teeth into place as they grow older.

Each baby tooth will eventually fall out, making room for the permanent teeth. Understanding the structure and function of these baby teeth can help ensure proper care from the earliest stages of dental development.

Understanding Baby Teeth: Types and Functions

Baby teeth are divided into several categories, each serving a different purpose in your child’s mouth. Here’s a breakdown of the types of teeth your child will have:

Incisors (8 total)

  • Location: Four on the top and four on the bottom.
  • Function: Incisors are the sharp teeth at the front of the mouth used for biting into food.

Canines (4 total)

  • Location: Two on the top and two on the bottom, next to the incisors.
  • Function: Canines are pointed teeth used to tear food.

Molars (8 total)

  • Location: Four on the top and four on the bottom, at the back of the mouth.
  • Function: Molars have a flat surface for grinding and chewing food.

So, how many molars do kids have? Children will have eight molars as part of their set of 20 baby teeth.

When Do Baby Teeth Come In?

Teething typically begins around 6 months of age, though it can vary for each child. Most children will have all 20 of their baby teeth by the time they turn 2 or 3 years old.

Here’s a general timeline for when your child’s baby teeth will come in:

  1. Lower Central Incisors: 6-10 months
  2. Upper Central Incisors: 8-12 months
  3. Upper Lateral Incisors: 9-13 months
  4. Lower Lateral Incisors: 10-16 months
  5. First Molars: 13-19 months (bottom) and 14-18 months (top)
  6. Canines (Cuspids): 16-22 months (top) and 17-23 months (bottom)
  7. Second Molars: 23-31 months (bottom) and 25-33 months (top)

By following this timeline, you can track your child’s teething progress and know when to expect each tooth to appear. When do baby teeth start coming in.


How Many Teeth Does a Child Lose?

Once your child’s baby teeth have fully erupted, they will start losing them around the age of 6 years old. This process, called exfoliation, makes room for the 32 permanent teeth that will take their place.

Here’s how the baby teeth usually fall out:

  • Incisors: The first to go, between ages 6-8.
  • Canines: Typically lost between ages 9-12.
  • Molars: The last baby teeth to fall out, usually between ages 10-12.

By the time your child reaches their teenage years, all 20 baby teeth will have been replaced with permanent ones.

How Many Molars Do Children Have?

One of the most common questions parents ask is: “How many molars do kids have?”

As part of the 20 baby teeth, children have 8 primary molars. These molars are crucial for chewing and grinding food. Eventually, these molars will be replaced by permanent teeth, including the first, second, and possibly third molars (also known as wisdom teeth).

Caring for Baby Teeth: Key Tips for Parents

Maintaining healthy baby teeth is just as important as caring for permanent teeth. Baby teeth not only help your child chew and speak, but they also hold space in the jaw for the permanent teeth that are growing underneath the gums.

Here are some tips to ensure your child’s teeth remain in good condition:

Start Early with Oral Care

You should begin cleaning your baby’s mouth even before the first tooth appears. Use a soft, damp cloth to gently wipe their gums. Once the first tooth appears, start using a baby toothbrush with a small smear of fluoride toothpaste.

Fluoride is Essential

Fluoride strengthens enamel, making teeth more resistant to decay. Consult your dentist to ensure your child gets the right amount of fluoride, either through toothpaste or water.

Establish a Routine

Make sure your child brushes their teeth twice a day with fluoride toothpaste. It’s also essential to introduce flossing once they have two teeth that touch each other.

Limit Sugary Foods and Drinks

Sugary foods and beverages can cause cavities. Encourage your child to drink water and eat healthy snacks to protect their teeth.

Regular Dental Checkups

Schedule your child’s first dental visit by their first birthday or when their first tooth comes in, whichever comes first. Regular dental visits ensure any potential problems are caught early.


The Importance of Baby Teeth for Future Dental Health

You might think that baby teeth are temporary and therefore less important, but they play a critical role in your child’s future dental health. Baby teeth act as placeholders for permanent teeth, guiding them into the correct position. Losing baby teeth too early—due to decay or injury—can cause alignment issues in the future.

Additionally, healthy baby teeth contribute to your child’s ability to eat properly, which is essential for overall growth and development.
