When Do You Get Adult Teeth? Eruption Timeline & Sequences

Teeth development starts in the mother’s womb in the fifth gestation week. At birth, the baby has deciduous teeth in the upper and lower jaws and some permanent teeth developing in the jaws. Now, the question is, when do you get adult teeth, and how do you maintain them? 

So, in this blog, we will discuss the right age for developing adult teeth. Further, we will look into permanent teeth eruption age charts and adult teeth charts. Continue scrolling to learn when permanent teeth come in and how you should care as a new parent.

Now, let’s move forward and learn about different types of teeth and their time of eruption. 

Types of Teeth:

There are different types of teeth, from the deciduous baby teeth to the molars and canines. Here is the description of each type:

Incisors

These are the teeth in the upper and lower jaws, each with a thin cutting edge. They act as a pair to cut the food, grind it, and help chew it. 

Canines

The next type of adult teeth is canines. It covers the pointy teeth on both sides of the incisors in the upper and lower jaws. They are perfect for tearing food. 

Premolars

The premolars, also common as bicuspids, sit between the canines and the molars. They have flat surfaces, and their primary task is to crush food. 

Molars

The last type of the teeth is molars. In this type, the teeth are more prominent than premolars and are present at the back of the mouth. In addition, they are broad with flat surfaces that help grind and churn the food. 

All these four types combine to cover the whole space, and all types have different roles.

Primary Vs. Permanent Teeth

The babies start erupting their teeth around 6-8 months and gradually develop 20 primary baby teeth. These teeth grow in half, 10 in the upper jaw and 10 in the lower jaw.

These baby teeth are common as primary teeth and serve several purposes, such as chewing, holding the right amount of space, and correct space. 

An interesting fact about the primary teeth is that the lower teeth typically grow before the upper jaw, and girls tend to begin to erupt first than boys. Furthermore, the kids have a complete set of teeth between 2 to 3 years of age. 

On the other hand, a set of permanent teeth composed of 16 upper jaw teeth and 16 lower jaw teeth are replaced over many years. Permanent teeth, such as six yearly molars, emerge in the place where a baby’s teeth didn’t formally house. 

Additionally, permanent teeth need optimal oral hygiene and care to preserve them for the later stages of life.

If the baby teeth fall out or are removed, there is a chance that the space maintained for adult teeth may be jeopardized, which causes significant problems with eruption and spacing. 

Right Age to Start Getting Permanent Teeth:

If you are a new parent and thinking about the adult teeth of your baby brings vision to your mind, don’t worry. You will be surprised to learn that your kid’s first permanent tooth is usually not replaced but the one that erupts in the space. 

The first molars are the primary teeth, including eight molars, and are the first permanent molars your baby will get. 

Once the first molars erupt, the child starts losing the teeth and grows replacement.

In this way, the baby’s teeth continue to fall out, and permanent teeth remain replaced until a child is around 11 to 13. 

Here is the permanent teeth eruption age chart that shows the typical timing for the eruption of permanent teeth, when second molars come in, and the right age of developing canines in kids.

Do Permanent Teeth Ever Grow Before Baby Teeth Fall Out?

Here comes another exciting question that parents might feel curious about. Parents might wonder if the permanent teeth grow in before baby teeth fall out. In short, the answer is yes; it happens more commonly. 

The permanent teeth begin erupting and start pushing against the roots of the primary teeth, which they replace after.

The primary tooth roots are discovered, resulting in the loosening of the baby tooth, which eventually falls out. 

However, the process only sometimes works correctly; sometimes, the permanent tooth grows without the primary tooth becoming loose.

Further, no treatment is necessary as the baby’s teeth eventually fall out independently. However, a pediatrician can recommend better solutions to combat such a situation. 

Take away:

To sum up, primary and permanent teeth grow at their own pace. Both have different eruption ages and occur on their own time.

However, there are other circumstances which can occur. Parents must visit a pediatric dentist in exceptional circumstances and share their concerns about their kids’ teeth.
