Anatomy of the Primary Dentition


There are different names for your children’s ‘first’ teeth. These are baby, milk, deciduous, and primary.

The precise dental terms are deciduous or primary…for the purpose of this blog, we’ll call them primary.

By the age of two and a half, most children have their full set of primary teeth. There are 20 in total.

Many parents are eager to know when their children’s primary teeth are going to erupt into the mouth.

In addition, they want to know when ‘these’ teeth will shed (fall out).

Below is a chart which explains when the primary teeth erupt and when they shed and the adult teeth come into the mouth to replace them.

As parents, we tend to get upset and bothered if there’s a lag in any aspect of our child’s development.  We just want everything to be ‘normal.’ The same goes for the primary teeth.

What I always tell concerned parents is that they shouldn’t get too hung up on when the primary teeth fall out or the adult teeth erupt. Some children may be earlier or later than others in this respect.

What matters most is the sequence of eruption of the teeth. If all 20 of the primary teeth are not in your child’s mouth by two and a half years of age, it is not a ‘catastrophe’…as mentioned previously, some children may be earlier and some later.

The next blog is going to be a real eye opener for many parents. We’re going to take look at what’s going on in your child’s jaws…please stay tuned!
