After your child has lost one or more of their baby teeth and the tooth fairy has collected them, the next step is to wait for the arrival of their adult teeth. In some cases, you may even see part of their permanent teeth starting to erupt before their baby teeth have completely fallen out. But, what about if one or more permanent teeth are not coming in? In rare cases, it can take as long as a year. Here are some of the reasons why:. One of the most common reasons that permanent teeth do not erupt properly is because there is not enough space for them. Since permanent teeth are wider than baby teeth, it is natural for baby teeth to have gaps between them.

Some of them may be more parental anxiety than anything else. However, there are some concerns that may need to be addressed. A common concern is wondering about reasons for adult teeth not coming in after they have lost their primary or, baby teeth. For issues such as this, your child may need braces to move their teeth around and make room for the permanent ones.

Most parents regard a lost baby tooth as a considerable milestone for their children. Unfortunately, this excitement can turn to worry, when permanent teeth do not erupt as they should. For permanent teeth to erupt, there must be sufficient space. Ideally, there should be some space on either side of baby teeth before they fall out.
