Wisdom teeth, also known as third molars, are the last set of teeth to develop at the back of the mouth, both in the upper and lower jaws. They typically emerge between the ages of 17 and 25. Here are some functions and information about wisdom teeth:
Functions of Wisdom Teeth
- Replacing Lost Teeth: In ancient times, wisdom teeth might have had a more significant role when humans often lost teeth due to a rough diet involving raw or hard foods. Wisdom teeth could replace teeth that were lost due to wear or damage.
- Aiding in Chewing: Like other molars, wisdom teeth help in chewing food, particularly those that require more grinding.
Current Realities of Wisdom Teeth
- Reduced Function in Modern Times: With the development of softer diets and advancements in dental care, the function of wisdom teeth has become less important. Many people do not have enough space in their jaws for wisdom teeth to grow properly.
- Common Problems:
- Impaction: Wisdom teeth often grow at an angle or do not fully emerge from the gums, known as impaction. This can cause pain, infection, and other issues.
- Damage to Adjacent Teeth: Misaligned wisdom teeth can push against other teeth, causing damage or shifting of teeth.
- Infection and Inflammation: Partial eruptions can allow bacteria to enter the open gums, leading to infections, inflammation, and swelling.
- Cysts or Tumors: Improperly growing wisdom teeth can lead to cysts that may damage the jawbone structure.
Removal of Wisdom Teeth
- Preventing Problems: Due to the potential complications, many dentists recommend the removal of wisdom teeth, especially if they pose a risk of causing future issues.
- Evaluation and Planning: A dentist or oral surgeon typically evaluates the position and condition of the wisdom teeth through X-rays before deciding whether the teeth need to be extracted.
Conclusion
While wisdom teeth may have served a clearer function in the past, in modern contexts, they often cause more problems than benefits. Therefore, many people opt to have their wisdom teeth removed to prevent potential complications.
