How many wisdom teeth in human mouth?
In the human mouth, there are typically four wisdom teeth, also known as third molars. These teeth are located at the back of the mouth, on both the upper and lower jaws. Wisdom teeth are the last set of molars to erupt, usually between the ages of 17 and 25. However, not everyone develops all four wisdom teeth, and some individuals may have fewer or none at all.
Origin and Purpose of Wisdom Teeth
The origin of wisdom teeth dates back to the time when our ancestors had larger jaws and consumed a diet rich in tough foods. Wisdom teeth served as additional molars to help grind down the tough and fibrous foods. As humans evolved, their jaws became smaller, and their diet shifted to softer foods, which resulted in less need for these additional molars. This is why wisdom teeth are often referred to as “vestigial” or “redundant” teeth.
While the purpose of wisdom teeth may no longer be as essential as it was in our ancestors, they can still cause various dental problems. The lack of space in the mouth for wisdom teeth to erupt properly can lead to impacted wisdom teeth, which may cause pain, swelling, and infection. In some cases, wisdom teeth can also affect the alignment of the surrounding teeth, leading to crowding or misalignment.
Types of Wisdom Teeth
There are four types of wisdom teeth, each with its own characteristics:
1. Mesioangular: This type of wisdom tooth is positioned at a slight angle towards the front of the mouth.
2. Distal angular: This type of wisdom tooth is positioned at a slight angle towards the back of the mouth.
3. Vertical: This type of wisdom tooth is positioned vertically in the mouth.
4. Horizontal: This type of wisdom tooth is positioned horizontally in the mouth.
The position and angle of wisdom teeth can significantly impact their potential to cause dental problems.
Wisdom Teeth Extraction
In many cases, wisdom teeth need to be extracted to prevent or treat dental problems. Extraction is typically performed by a dentist or an oral surgeon under local anesthesia, sedation, or general anesthesia. The procedure involves removing the tooth from its socket in the jawbone.
The decision to extract wisdom teeth is based on various factors, including the position of the teeth, the presence of any dental problems, and the patient’s overall oral health. In some cases, wisdom teeth may be left in place if they are fully erupted and not causing any issues.
While wisdom teeth extraction is a common dental procedure, it is essential to consult with a dental professional to determine the best course of action for your individual situation.
Conclusion
In conclusion, the human mouth typically contains four wisdom teeth, which are the last set of molars to erupt. These teeth have evolved from their original purpose and can now cause various dental problems. Wisdom teeth extraction is a common procedure performed to prevent or treat dental issues. If you have concerns about your wisdom teeth, it is essential to consult with a dental professional to ensure the best possible outcome for your oral health.
