Top 6 Reasons For Delayed Teeth Eruption In Children

Losing one or more baby teeth (primary teeth) is a key moment in your little one’s development. It is an indication that your child is marching toward adulthood and has outgrown his or her primary teeth. But, if your child’s permanent teeth do not erupt within the standard timeframe, it might cause you some concern. While there are many reasons why this could happen, a slight delayed tooth eruption shouldn’t be a major concern. However, if the permanent tooth eruption pattern seems abnormal or there are no teeth until 6 months or longer since your child has lost a baby tooth, you should have your little one evaluated by a dental professional. In the meantime, let’s look at some of the common reasons your child’s permanent teeth may be delayed in arriving.

When are Permanent Teeth Supposed to Erupt?

Children are born with a full set of 20 primary or baby teeth within their gums that usually start breaking through their gums’ surface by the age of three. After that, they start losing their primary teeth between ages 6 and 7 years (though it can occur earlier or later). These 20 primary teeth are completely replaced by permanent teeth. However, some children don’t get their permanent teeth at expected time periods. While delayed tooth eruption is not a major cause of concern, it never hurts to check.

Here’s Why your Child’s Permanent Teeth are not Coming In

Did your little one loses a primary tooth months ago and there is still no sign of a permanent or replacement tooth?  Listed below are some common reasons why this sometimes happens.

1. Lack of Space

Lack of space in the mouth is one of the most common reasons why your little one’s permanent teeth are not coming in. When there is not enough room for the permanent teeth, they will not come in. This can happen if your little one’s primary teeth lack required spaced between them. Also, because the permanent teeth are bigger in size than the primary ones, the gaps between primary teeth allow for the eruption of a replacement tooth.

2. Impacted Teeth

Sometimes children have impacted teeth that prevent permanent teeth from coming in. This can result from premature loss of primary teeth or narrow jaws. Without enough space to appear, permanent teeth will develop completely underneath the gums, causing a number of dental issues. If addressed soon enough, dental professionals can correct this without long-term issues.

3. Extra Teeth

Hopefully, everyone knows that children and adults have different sets of teeth. In general children have a set of 20 primary teeth and adults have 32 teeth, but some children are born with extra teeth in addition to the normal 20 primary teeth and dental professionals call this dental condition “hyperdontia”. This leads to a range of problems because the extra teeth take up the space where replacement teeth are supposed to come in, resulting in insufficient space, overcrowding and impacted teeth.

4. Nutritional Deficiency

The nutritional habits of your child can greatly impact the development of the adult teeth. Any deficiency in calcium and essential vitamins can significantly impact your child’s teeth eruption process. It is important to note that children particularly need more calcium and other essential minerals for the development of their permanent teeth. Also, children who regularly consume sugary and acidic foods can slow down the growth of their adult teeth. Overall, it is important to make sure that children stick to a healthy diet and learn how healthy eating habits can drastically improve their dental health.

5. Heredity Factors

There is also some research into heredity factors affecting when permanent teeth will appear. If delayed permanent teeth eruption runs in the family, then it should come as no surprise that there will be a delay in the eruption of your child’s permanent tooth. Parents should check with their parents and relatives to find out if delayed teeth eruption runs in the family. In case if it does not, and it has been more than 6 months your child has lost his or her baby tooth, then you should consult a dentist.

6. Certain Medical Conditions

Last but not least a final reason for your child’s permanent teeth may be delayed in arriving is due to specific health conditions that affect the development and growth of bones. Some of the medical conditions include Down’s syndrome, rickets, fibrous dysplasia, and hypothyroidism.

The bottom line

At the end of the day, your child’s first permanent tooth eruption is a big deal that calls for celebration, even though he or she might have to deal with some teething symptoms.  As already discussed, the permanent teeth should erupt no later than 6 months after a child has lost a baby tooth. There’s nothing to panic about if there’s a delay. But if there’s no sign of permanent tooth erupting within the standard timeframe, arrange a dental visit for evaluation and treatment.
