How Long Does It Take For Teeth To Grow?

Knowing the schedules for baby teeth and permanent teeth eruption can be helpful in child rearing-. But how long does it take for teeth to grow?

Being a new parent can be nerve-wracking. Even if you’d had experience with siblings or nephews and nieces. Like any good parent, you want to make sure they grow up strong and healthy. Often, you might find yourself spiraling down a vortex of medical and parenting sites to see if your child is developing the right way. And in terms of their dental health, it’s no surprise that one of the most common questions is how long does it take for teeth to grow. 

And it’s no small inquiry, either. Knowing how long it takes for teeth to grow in has a more significant impact on childcare than you’d think. It’s one way to signal what your baby can and can’t eat, and when they need to see a pediatric dentist. 

More importantly, knowing how long does it take for teeth to grow also clues you in on the state of their oral health. While every child is different, having teeth that grow in too late or are lost too early can signal an emergency trip to the dentist. 

That said, let’s look at how long does it take for a tooth to grow.

Baby teeth come in around 4-8 months

To know how long it takes for teeth to grow, understanding how teeth develop in the womb might make things a little easier. The Dental Health Foundation of Ireland outlines the development as follows:

  • Three weeks after conception, the mouth begins to form, along with everything else associated with it. The following weeks refine these features, such as the palate and jaw.
  • Six weeks after conception, the tooth buds begin to form. These buds will eventually develop into your child’s baby teeth. 
  • Eight weeks after conception, all the buds of the primary teeth have formed.
  • Twenty weeks after conception, the tooth buds of the adult teeth begin to form. 

Your child’s teeth continue developing after birth, which is why it takes a while for them to erupt. Some kids, however, might already be born with teeth (called natal teeth), particularly those with medical issues. Children with natal teeth may not necessarily be at risk for something, it might be best to consult your pediatric dentist in case of a choking hazard.

How long does it take for teeth to grow in this stage, then? Usually, around 4-8 months, depending on the child. By 2 years of age, your child should have their full set of baby teeth in, ready for shedding.  

Permanent teeth eruption usually starts at 6 years of age

Some years after your child gets their full set of primary teeth, you’d think they’d begin to shedding right away. Not really, as it turns out. Permanent teeth eruption, after all, usually occurs at the same rate as your mouth development. 

Your child’s baby teeth usually suffice until they’re 6 years old. At that age, then, their bodies begin to undergo significant physical changes as they inch closer to puberty. It’s also at that age that they start to shed their baby teeth as permanent teeth eruption begins to occur. And this cycle of shedding and emergence then continues until your child is around 13-14 years of age.
