Wisdom teeth are among the most discussed -and misconceived- aspects of our dental structure. Virtually every person has an experience of wisdom teeth pain, Wisdom Teeth Removal, or an unexpected Dental Emergency due to it. But have you ever wondered: why do we have wisdom teeth, and why are they so bad?
This article will discuss the purpose of wisdom teeth, their evolutionary background, the wisdom tooth issues and solutions, and why experts now advise that you should not get your wisdom teeth removed unless it’s necessary.
What Are Wisdom Teeth, and how many do we have?
Wisdom teeth are the third and last group of molars. They normally develop between the ages of 17 and 25. The majority of individuals possess four wisdom teeth; two upper ones and two lower ones, but some individuals may have fewer or even none.
The Evolutionary Account of Wisdom Teeth
The history of wisdom teeth narrates a curious tale of human evolution and the shift of diet over the thousands of years. The eating patterns of our ancestors were vastly different than those of modern humans as they ate raw meats, roots, nuts, and rough vegetation which demanded strong chewing power. These rough, fibrous foods led to significant wear on teeth over a lifetime of a person, and in many cases, to the loss of teeth in early adulthood.
What are wisdom teeth used for in this context? They were natural substitutes to lost or decayed molars, meaning that our ancestors were able to keep on processing their challenging diets well into adulthood. The jaw structure of early humans was also much larger and these third molars could come out and work well. What is the number of our wisdom teeth? Humans normally have four wisdom teeth, one in each corner of the mouth, but some individuals might have fewer or no wisdom teeth because of genetic differences.
Wisdom teeth used to be a perfect sense in prehistoric times, but nowadays human evolution has transformed our needs significantly. Our jaws have been reduced over a millennium, partly due to changes in diet and food preparation. Food processing, agriculture, and cooking have made our food softer and easier to chew, and the evolutionary pressure to maintain large and strong jaws has been reduced. Meanwhile, we are keeping our original teeth much longer than our predecessors because of the improved dental treatment and cleaning of teeth.
Why Wisdom Teeth Often Cause Problems
The main issue with wisdom teeth today is associated with space. The reason why wisdom teeth do not fit is simply a misalignment between the size of the jaw and the number of teeth. Although we still have the genetic programming of four wisdom teeth, our jaw structure has become smaller and more refined. This evolutionary delay implies that the majority of individuals simply lack the space to accommodate these extra molars.
The reason why wisdom teeth grow sideways brings out another aspect of this spacing problem. In cases where adequate space is not available to allow healthy vertical eruption, wisdom teeth can be impacted, developing at angles relative to neighbouring teeth or being trapped under the gum line. This is known as impaction and is one of the most prevalent forms of wisdom teeth problems, and is commonly solved by either monitoring or removal.
The eruption of a wisdom tooth may take various courses. Others develop in parts, forming a flap of gum tissue that is hard to clean and easily infected. Others can advance over the second molars, resulting in crowding and possible damage to adjacent teeth. In a few lucky situations, wisdom teeth come out straight and functionally and do not give any problems at all.
Problems and Remedies of Wisdom Teeth
- Wisdom Teeth Pain: Causes and Severity Levels
Among the most common complaints related to these late-blooming molars is wisdom teeth pain. This pain may be due to a variety of factors, such as the pressure of eruption, inflammation of adjacent gum tissue (pericoronitis), or infection in partially erupted teeth. The discomfort can be occasional or persistent, and can be mild or severe pain that can be considered a dental emergency.
- Complications from Impacted Wisdom Teeth
Affected wisdom teeth pose special problems to oral health. These teeth may develop cysts or destroy the roots of other teeth when they are stuck under the gum or grow at the wrong angle. The challenge of cleaning partially erupted wisdom teeth also heightens the risk of dental carries since food particles and bacteria can be deposited in inaccessible locations. It makes cleaning of teeth difficult and even brushing and flossing might not be sufficient to protect these weak spots.
- Gum Disease and Infection Risks
Gum disease can also be caused by the position and partial eruption of wisdom teeth as the bacterial plaque accumulates around the gum flap that covers a partially erupted tooth. This may result in swelling, pain and infection which can extend to other parts of the mouth unless treated. In some cases, patients report jaw stiffness, inability to open their mouth completely, or even swollen lymph nodes in case of complications with wisdom teeth.
Why Experts Now Say Not to Remove Your Wisdom Teeth
In the past, preventive removal was common. However, research now shows that why experts now say not to remove your wisdom teeth unless there is a clear problem is because unnecessary surgery can increase risks such as nerve damage, infection, and prolonged recovery.
The benefits of keeping wisdom teeth include:
- Maintaining jawbone density
- Supporting natural chewing function
- Avoiding unnecessary surgical complications
If wisdom teeth are healthy, fully erupted, and easy to clean, dentists may recommend keeping them.
When Wisdom Teeth Removal Is Necessary
Despite the benefits, Wisdom Teeth Removal may still be required if:
- The tooth is impacted or growing sideways
- There is repeated infection or severe wisdom teeth pain
- Dental caries cannot be treated effectively
- The tooth causes damage to the surrounding teeth
In some cases, removal becomes a Dental Emergency if swelling or infection spreads.
Conclusion
The wisdom teeth aren’t inherently bad they are just a remnant of our evolutionary history. Knowing the reason why we have wisdom teeth, their purpose, and the possible issues that may arise will assist you in making informed decisions instead of basing them on old myths.
