The permanent tooth coming in behind baby tooth can be pretty terrifying.
Those two rows of teeth are called shark teeth.
Quite an intimidating name, right?
They mostly grow behind the baby tooth in the lower units.
And if this is a frequent case, you must immediately take specific steps so the adult teeth and their eruption proceed properly.
In the following, we will introduce you to the causes; we will answer the question of the possible consequences and how to solve this problem effectively.
Permanent Teeth in Children – Order of Eruption
Baby teeth begin to erupt around the sixth month of life and finish at the age of two.
The child has ten teeth in each jaw – from one to five.
In some cases, it is rare, but some babies are born with a tooth or even two teeth.
In that case, you will immediately have to schedule appointment with pediatric dentistry.
A pediatric dentist will tell you to keep an eye on those teeth and that they will have to take them out if they start to become loose. If not, the baby could swallow it.
Let’s continue talking about the eruption of teeth.
The eruption of permanent teeth starts at the age of six.
The first permanent tooth that erupts is the permanent sixth. There is room behind the baby fifth without extracting the baby teeth.
Often, parents do not recognize this tooth but think it is a baby tooth.
The eruption of the sixth baby tooth is usually followed by permanent teeth one and two. Fours and fives grow after them, and finally, threes. They are now called adult teeth.
Unlike sixes, the emergence of these teeth is conditioned by the previous extraction of baby teeth.
Why is The Permanent Tooth Coming Behind Baby Tooth?
To answer this question, we will first say what happens when permanent teeth erupt.
The conviction of some people that a baby tooth does not have a root is wrong!
On the contrary, a baby tooth has a root, just like an adult tooth has.
As a rule, the place for a permanent tooth is located directly under the root of a baby tooth.
During the eruption, the permanent tooth resorbs the baby tooth’s root. During this process, as the baby tooth loses its root, it gradually loosens and eventually falls out.
If everything is correct, the tooth’s root is resorbed so much that it practically does not exist anymore. The tooth falls out most often during food intake, at the slightest movement.
As we stated earlier, the permanent tooth grows behind the baby tooth, most often in the space of the lower units. This occurs most often because the seed of the permanent tooth is slightly moved towards the oral cavity in relation to the baby tooth.
In this situation, the permanent tooth does not properly absorb the root during growth but only absorbs its inner half, so the baby tooth does not unfold properly.
This can also happen with fours and fives. Baby teeth four and five are molars, and adult teeth four and five are premolars. The permanent fourth premolar can be the same or smaller than the baby fourth molar.
If it is smaller, it often cannot fully absorb the root, so the tooth begins to grow next to the baby tooth.
All these are relatively common and regular occurrences. However, if you don’t react on time after changing the teeth, the teeth will not be aligned in a perfect size but will be crooked.
What To Do if the Tooth is Coming in Behind the Baby Tooth?
You should do the following:
1. A visit to pediatric dentistry – the dentist will evaluate whether it is necessary to wait or whether the tooth should be extracted.
2. Scan of the teeth – unless the stage is already advanced where everything is visible to the naked eye, the dentist will most likely require scanning the teeth to determine which teeth are coming out earlier than expected.
3. Extraction of a baby tooth – the most likely scenario is that the dentist will extract a baby tooth and they do that so that the permanent tooth can take its place, grow correctly, and form a regular tooth row.
This extraction can be painful because the root is not gripped. Therefore, take care the child does not get traumatized.
Experienced dentists either have the technique and know how to give anesthesia to a child or use an anesthetic in a spray so they do not feel it. They usually use a drug in a spray because children are not afraid of it.
4. Orthodontic therapy – if you have waited, there is every chance that the child will have to wear an orthodontic brace to straighten teeth and that an orthodontist specialist will monitor the progress of the therapy.
If the permanent tooth grows behind the baby tooth, no matter how hard you try, you cannot prevent this because it is not up to you.
You can visit the pediatric dentist as soon as you notice a problem.
In the end, you should pay attention to the baby teeth to protect them and the permanent ones that will come after them from damage.
Baby teeth should keep their place until the end. In this way, they secure a place for permanent teeth. Also, the premature loss of baby teeth can encourage the eruption of permanent teeth, which can take the wrong position in the dental arch.
On the other hand, baby teeth often do not fall out in the order described in the textbook, which leads to specific difficulties.
Thus, there are cases in which children’s baby teeth do not fall out after the permanent ones have erupted, which leads to irregular teeth arrangement and subsequent more complicated and long-term orthodontic treatments.
Baby teeth should therefore be extracted at a time when there is no room for permanent teeth to erupt or when permanent teeth begin to grow in front of or behind baby teeth.
This also enables more regular eruption of permanent teeth and easier eventual orthodontic treatment.
Be in touch with pediatric dentistry, and everything will be alright with that tooth coming in behind baby tooth or so-called shark teeth. You just make sure the tooth fairy gets nice clean teeth.
