This chart shows when baby teeth erupt and fall out. Remember that eruption times can vary from child to child, and this is a general guide.

You can see from the chart, their first teeth begin to break through their gums at about 6 months of age.

Usually, the first two teeth to erupt are the two bottom central incisors (the two bottom front teeth).

Next, the top four front teeth emerge.

After that, other teeth slowly begin to fill in, usually in pairs – one each side of the upper or lower jaw – until all 20 teeth (10 in the upper jaw and 10 in the lower jaw) have come in by the time the child is 2 ½ to 3 years old.

The complete set of primary teeth is in their mouth from 2 ½ – 3 years old to 6 – 7 years of age.

Other primary tooth eruption facts:

• A general rule of thumb is that for every 6 months of life, approximately 4 teeth will erupt
• Girls generally precede boys in tooth eruption
• Lower teeth usually erupt before upper teeth
• Teeth in both jaws usually erupt in pairs – one on the right and one on the left
• Baby teeth are smaller in size and whiter in colour than the permanent teeth that will follow
• By the time a child is 2 – 3 years of age, all baby teeth should have erupted

Shortly after their 4th birthday, the jaw and facial bones of a child begin to grow, creating spaces between their baby teeth. This is a perfectly natural growth process that provides the necessary space for the larger permanent teeth to emerge. Between the ages of 6 and 12 years, a mixture of both baby teeth and permanent teeth reside in their mouth.

If baby teeth fall out after a couple of years, why is caring for them so important?

While it’s true that baby teeth are only in their mouth a short period of time, they play a vital role in the following ways:

• They reserve space for their permanent counterparts
• They give the face its normal appearance
• They aid in the development of clear speech
• They help attain good nutrition (missing or decayed teeth make it difficult to chew causing children to reject foods)
• Early loss of baby teeth can affect the proper growth of their jaws

Permanent teeth eruption chart

The following chart shows when permanent teeth emerge.

In some children, their first permanent molars emerge first; in others, their incisors are the first to emerge.

By the age of 13, most of their 28 permanent teeth will be in place.

One to four wisdom teeth, or third molars, emerge between the ages of 17 and 21, bringing the total number of permanent teeth up to 32.
