When Do Children Get Their Full Set of Teeth?

Tooth development occurs in four main stages. By the age of three, the average child has a full set of 20 primary teeth. Between the ages of six and seven, the primary teeth begin to fall out as permanent teeth emerge. Knowing about these stages is important so you can better prepare your child for any orthodontics they may need in the future. Let’s take a closer look at these stages.

The Teeth Eruption Stages

Around six months, the first teeth begin to erupt. The bottom central incisors are usually the first two teeth to emerge. Next to appear are the top four incisors. Following that, other teeth gradually begin to fill in, often in pairs with one on either side of the lower and upper jaw until all 20 teeth are in place. This usually happens when a child is two to three years old. The entire set of primary teeth is typically formed between three and six to seven years.

Other Tooth Eruption Milestones

On average, four teeth emerge every six months. In most cases, the lower teeth appear before the upper ones. They typically erupt in pairs, with one set on the right and another on the left. As more teeth erupt, it’s usually a good idea to start seeing a dentist for check-ups to ensure everything is growing as it should.

The Full Set of Teeth

All twenty primary teeth should have broken through by the time a child is two or three years old. Permanent teeth tend to be larger and darker in color than primary teeth, which are smaller and whiter. It’s more common for a girl’s teeth to come in before a boy’s.

Spaces between the baby teeth occur when the jaw and facial bones of a child continue to develop, shortly after age four. This is a normal stage in teeth development that makes room for the adult teeth that appear later as the child ages. At the ages of six and 12, children still have a combination of baby and adult teeth.

Remember that although permanent (adult) teeth will replace your child’s primary (baby) teeth, it doesn’t mean you should disregard their dental and orthodontics exams in the meantime. Taking care of your child’s teeth during their formative years can set the stage for a lifetime of good dental hygiene. It can also help catch issues early on before they become big problems.

According to creation smiles, many orthodontics professionals recommend that children begin their orthodontist exams after permanent teeth have emerged, often around age seven. However, if you see anything out of the ordinary, don’t hesitate to make an appointment with an orthodontist. We are here to help. Give us a call today to book an appointment.
