The wisdom teeth are the last molars to emerge. They grow in late adolescence or early adulthood between the ages of 18 and 25. However, dental sprouts are already present from the age of 11 or 12. There are four, two at the top and two at the bottom.
However, in some cases, wisdom teeth can cause some complications in the mouth, so many people today choose to get rid of their wisdom teeth via dental surgery.
Wisdom teeth: what is it ?
The last molars on each side of the jaw are named the wisdom teeth. These are the last teeth to emerge, and they are developed through childhood. Some people have four, while others have none.
In any case, when we talk about wisdom teeth, a variety of scenarios can arise:
- They can be rooted in the jaw bone and never grow.
- They can be semi-embedded. One part may be visible in the cheek, while the other part may stay under the gum.
- They could erupt. They could grow and fill up the space between the second molar and the growing branch of the mandible.
Today, wisdom teeth are no longer useful. Thousands of years ago, our ancestors had a regimen based on raw beef, root and nuts. Chewing required a lot of effort, and their teeth were worn out very easily. Subsequently, new teeth appeared to replace the molars used.
Little by little, the teeth of wisdom have decreased in size and the jaw has shrunk. Our diet has also evolved greatly since prehistoric times and two molars are now enough.
Wisdom teeth: why remove them?
It is not compulsory to remove wisdom teeth. If they stay in the bone without causing any discomfort or if they have enough room to push through and appear in a decent position, the dentist will not intervene.
The teeth will only be removed in very particular cases:
- When cysts or tumors form
- To avoid infection as the wisdom tooth is semi-enclosed and partly covered with gingiva.
- Create room as part of an orthodontic procedure
- Wisdom teeth might be angled and their growth can harm the neighboring teeth
- When the teeth of wisdom grow too close to the neighboring teeth, this can cause a loss of bone and gum in this area.
- If there's a tooth decay. It is often difficult to treat cavities in wisdom teeth due to their morphology, so it is usual to remove them to prevent the risk of recurrence.
Wisdom teeth: how to take care of them
Today, roughly 25% of people do not have wisdom teeth. Admittedly, nowadays, wisdom teeth are no longer relevant and they are becoming more and more of a nuisance.
Thus, it is not rare for wisdom teeth to be removed in order to prevent any pain in the mouth, such as the moving of teeth due to the appearance of wisdom teeth, or even the treatment of cysts or cavities.
