The problem of permanent teeth erupting while baby teeth do not fall out is a problem that tends to occur around kindergarten age to early elementary school age.
In addition to double dentition, permanent teeth may grow at an angle or the dentition may be uneven.
This time,This section explains what to do when permanent teeth erupt while baby teeth do not erupt, and what problems can occur when permanent teeth erupt while baby teeth do not erupt!
How baby teeth fall out
![Is it safe for permanent teeth to erupt when baby teeth don't fall out? 42 Permanent tooth even though the deciduous tooth does not fall out.](https://365dentist.jp/wp-content/uploads/2023/10/26607036_s.jpg)
Deciduous teeth are made to fall out when the roots of the baby molars are dissolved by the permanent teeth made in the gums.
As the permanent teeth grow, the roots of the deciduous teeth shorten so that they can no longer support the deciduous teeth and naturally fall out at the same time the permanent teeth come in.
Basically, one permanent tooth is created directly under one deciduous tooth, and the permanent tooth erupts after the deciduous tooth falls out.
Baby teeth usually erupt starting with the lower front teeth at about age 6, and the permanent dentition is usually complete by the time the child reaches junior high school age.
However, there are a surprising number of cases in which permanent teeth erupt while baby teeth do not for some reason.
This case is most often seen on the lower front teeth of children from about kindergarten age to early elementary school age.
What should I do if my baby teeth don't fall out and my permanent teeth come in?

If permanent teeth erupt while baby teeth have not fallen out,Check to see if the baby teeth are shaking and see what happens.
If there is no sign of baby tooth eruption after two weeks or more, it is recommended that you visit your dentist for a consultation.
First, check for wobbly baby teeth.
If there are any baby teeth left when the head of the permanent tooth is just a little visible,Touch the baby tooth to see if it wobbles.
If the baby tooth appears to be shaking, it is a sign that the baby tooth is getting ready to fall out.
Watch for about two weeks as the permanent teeth gradually become more wobbly during the process of eruption and may fall out spontaneously.
If the baby tooth has not fallen out after two weeks, but the wobble seems to be getting bigger, wait a little longer and it is likely to fall out naturally.
However, if the baby teeth are shaking but are painful when chewing food, in some cases it is better to extract them as soon as possible.
In these cases, it is recommended to see a dentist.
Talk to your dentist.
- No wobbling of baby teeth when permanent teeth erupt
- Permanent teeth have erupted, but the baby teeth are small and do not become more wobbly after more than 2 weeks
- Permanent teeth are coming in and baby teeth are about to fall out, but they are not falling out and there is pain.
In such cases, the roots of the deciduous teeth may not have dissolved for some reason, such as the incorrect position of the permanent teeth in the gums.
Since it is unlikely that the baby tooth will fall out naturally, consult your dentist.
When it is determined that "late remaining deciduous teeth" = "deciduous teeth have not been removed at the appropriate time," they are often extracted.
Problems with permanent teeth erupting while deciduous teeth do not erupt

If permanent teeth erupt while baby teeth do not, the following problems may occur
- Increased risk of tooth decay and periodontal disease
- Possible misalignment of teeth.
Increased risk of tooth decay and periodontal disease
When the deciduous and permanent teeth are in a two-tooth condition,Stains can accumulate between the two sets of teeth, increasing the risk of tooth decay and gum disease.
The space between the two teeth is difficult to brush and care for. In addition, the surface of newly erupted permanent teeth is still soft and prone to decay.
In some cases, it is better to extract the baby teeth early so that the permanent teeth can be properly cared for.
If a permanent tooth has erupted but the baby tooth is not wobbly and shows no sign of falling out, consult your dentist as soon as possible to protect the permanent tooth.
Possible misalignment of teeth.
When permanent teeth erupt to avoid deciduous teeth,This may result in future misalignment of the teeth.
Teeth alignment changes under the influence of tongue position and lip pressure. Therefore, permanent teeth that have just begun to erupt may naturally return to their correct position once the obstructing baby teeth are removed.
However, this is only the case for permanent teeth that have just started to erupt. Even if the baby teeth are removed after the permanent teeth have erupted, the misaligned teeth will basically not return to their proper position.
Note that if you want to correct misaligned teeth, you will need to use orthodontic treatment to move the teeth.
