Why Aren’t My Child’s Permanent Teeth Coming In?

The loss of baby teeth starts at around the age of 6 and continues until the child is 12 or 13 when new teeth stop growing and all baby teeth have been replaced. While it’s normal to see kids with missing big front teeth, as a parent, you may be wondering “When do the permanent teeth come in?” The answer varies from one child to the next. It can take as little as a week to as long as 6 months.

The slow growth of the permanent teeth is not something to be concerned about. However, if you are concerned about permanent teeth not coming in as expected or it is taking more than 6 months to grow, you should consult with a dentist to have your child’s dental health checked.

When teeth come in, they follow a general timeframe. However, listed below are the factors that can slow down or hinder the growth of your kid’s teeth.

 

  • Lack of Sufficient Space

Kids have natural spaces between their baby teeth to allow adult teeth to grow

Not having enough space for your kid’s permanent teeth to grow is perhaps the most common reason why they are not developing or erupting as expected. When the replacing permanent teeth are bigger than the baby teeth that have fallen out, there may not be sufficient space for the new teeth to erupt.

Kids have natural spaces between their baby teeth to allow the unhindered development of adult teeth. However, not all kids have those spaces. If this is the case, you have to visit a dentist to have any impediments around the teeth removed.

 

  • Directional Problems

The permanent teeth are supposed to follow the path of the primary teeth. Sometimes, when there are plenty of spaces, the teeth could grow in the wrong direction as they try to break through the gum. In some cases, permanent teeth can grow behind another.

Luckily, this dental problem can be fixed immediately to ensure that the permanent teeth erupt in the right direction. Tooth extraction and braces are often the best way to deal with this issue.

 

  •  Gender

Girls tend to develop their permanent teeth faster than boys do

Similar to how girls typically reach puberty before boys do, girls also tend to develop permanent teeth earlier than boys. If it takes a little longer teeth for your little boy’s teeth to grow, just be patient.

 

  • Genetics

The development of permanent teeth can also be affected by genetics. Research has shown that there is a genetic basis for dental health and anomalies. If you ended up needing braces during childhood, most likely, your kid would also end up needing them. If you are unaware of you and your spouse’s genetic history, you can always ask your parents or people who knew you from childhood to find out what causes the delay in your child or if there is a condition that needs the doctor’s attention.

It is also important to remember that tooth growth may also be inconsistent in kids with certain developmental or genetic disorders, like Down Syndrome.

 

  • Nutrition

Avoid food rich in sugar

Nutrition plays a significant role in the development of your child’s permanent teeth. For the teeth to develop correctly, it requires calcium, in addition to other minerals needed to make them strong enough to push through the gums. It is vital to ensure that your kids are eating a well-balanced diet early in life. As much as possible, avoid a diet rich in sugar.

Weight and height also have an impact on tooth development. Studies have revealed a connection between childhood obesity and the speed of permanent teeth growth. Taller children can also have their teeth earlier than their shorter counterparts.

 

  • Congenitally Missing Teeth

Congenitally missing teeth can also be the reason permanent teeth are not coming in. Permanent teeth may never develop at all. This is because people with this condition have at least one tooth missing from their adult set. It usually affects the wisdom teeth, but some may miss their lateral incisors and the second premolars.

The primary teeth will remain in place because there is nothing to push them out. If they are lost due to tooth decay, injury, or disease, no permanent teeth will take their place. Dentures or implants can be performed to replace the missing tooth.

 

  • Supernumerary Teeth

Supernumerary teeth are extra teeth that appear anywhere on the arch of your mouth. These additional teeth can potentially block the permanent teeth. Because they take up space meant for the permanent teeth, they can delay or displace their growth, causing dental problems.

Treatment varies but often involves extracting the extra tooth. Orthodontic treatment can also be recommended if there is a tooth or jaw misalignment.

 

  • Failure of Eruption

The primary failure of eruption is rare. It happens when the permanent teeth are present but fail to erupt or erupt only partially. The reason for this is genetic. Treatment can take a long time and consists of several steps, especially if there are multiple affected teeth. Oral surgery or orthodontics may be required to encourage growth.

Another reason for the failure is when the tooth is attached to the bone and unable to break loose. In which case, the dentist may choose to leave the teeth alone or recommend a cosmetic dentistry procedure.

 

  • Losing Primary Teeth Too Early

Tooth decay may cause children to lose their primary tooth prematurely

One of the main roles of primary teeth is to reserve the space for permanent teeth. Usually, a child loses their baby tooth when the corresponding adult tooth starts to erupt and pushes it out. However, if the baby tooth is lost too early, due to tooth decay or injury, the replacing permanent teeth may be ready to come in just yet.

Without replacement, the rest of the teeth would shift to occupy the empty area, causing misalignment. When it becomes too crowded, it can block the permanent tooth from erupting altogether. The tooth can either get stuck in the jaw bone or it only partially erupts and may look as if it has stopped growing. When the tooth is impacted, extraction could be required to resolve the situation.

To avoid this scenario, make sure that your kid is practicing good oral hygiene and is receiving proper nutrition. Visit the dentist regularly, too, for a check-up.

Visit a dentist regularly for a better assessment of your child’s dental health

Delays in permanent teeth development may be a concern for many parents, but you only have to remind yourself that the development of every child is unique.
