When Will My Child’s Adult Teeth Come In?

Some kids get their teeth earlier than others. It’s a very individualized process that depends simply on the body’s own timing. Even twins can differ in their tooth development.

Generally, girls tend to switch out teeth sooner than boys.

Knowing what to expect can help you keep you in-tune with your child’s oral health and natural tooth development.

First molars are the first adult teeth you can usually expect to see. These adult molars will show up at the very back of your child’s current set of teeth around 6 or 7 years of age.

Around the same time, the front four teeth on top and bottom will loosen by turn and fall out to make room for the grown-up versions.

Next, the lower canines (“eye teeth”) will take a turn swapping out (usually between the ages of 9-10 years old).

All of the adult premolars (bicuspids) will come in anywhere from 10-12 years of age. The upper canines should also come in at about this time.

Lastly, the second molars will erupt when your child is around 12-13 years old.

Again, these ages can vary from child to child and between genders. However, having an age-range to base it on can alert you to any problems that your child is experiencing in terms of tooth development.

No matter when the teeth arrive, your child’s smile needs maintenance through regular dental appointments. At checkups, the dentist will make sure all teeth are healthy, clean and developing normally. X-rays reveal if there are any problems with the adult teeth poised to replace baby teeth and are an essential part of the examination process.

Contact your child’s dentist to schedule an exam to learn exactly where your son or daughter is at in tooth development.

Eruption of Adult Teeth

The eruption patterns in children can vary greatly, typically with girls being ahead of boys when it comes to new teeth coming in. Most of the time, the first adult teeth to erupt are the first set of adult molars, also called “six year molars,” which consequently, erupt around the time of 6 years of age. These molars come in just behind the child’s 2nd set of primary (baby) molars…sometimes creeping in without the child or parent even realizing!

The lower front teeth are typically the next set of teeth to come in. Gradually, the front teeth are replaced with a permanent version of the tooth, with the cuspids (eye teeth) being one of the last front teeth to be replaced, as late as 12 years of age. Primary molars can also stay in place until about 12 years of age, making the entire eruption process of the majority of the permanent dentition stretch over a span of about 6 years or so, not including wisdom teeth.

Wisdom teeth are the 3rd set of molars. These teeth typically do not erupt or begin to cause problems until the range of 17-21 years of age, although they may wait until a person’s late 20s before being fully developed. Some people have to have their wisdom teeth removed due to inadequate space in the mouth, and the risk of abscesses or tooth decay.

As adult teeth begin to erupt, be sure to ask your dentist about placing preventive sealants on the molars. These protective applications help deter tooth decay in areas that are most prone to developing cavities.
