Wisdom teeth, also known as third molars, are the final set of teeth located at the back of your mouth. These teeth are often the last to emerge, typically making an appearance during late adolescence or early adulthood. Although many people experience no issues with their wisdom teeth, others face complications that require medical intervention. Understanding when and why wisdom teeth appear, as well as how to manage any discomfort, is essential to maintaining good oral health. In this article, we’ll explore the typical age range for getting wisdom teeth, the factors influencing their emergence, and what to do if you experience issues with them.
What Age Do You Get Your Wisdom Teeth?
Before discussing when wisdom teeth typically emerge, it is essential to understand their purpose and function.
1. The Function of Wisdom Teeth
Wisdom teeth were important for early humans, who had larger jaws and a tougher diet. These third molars helped in grinding down raw plant materials and meats, which required additional chewing power. Over time, as human diets evolved and jaws became smaller, the need for wisdom teeth diminished. However, wisdom teeth still grow in many people, despite being less essential in today’s modern diet.
2. Evolution of Wisdom Teeth
The evolutionary reduction in jaw size meant that many people no longer have enough room in their mouths for these teeth. While they may have once played a critical role in digestion, wisdom teeth now serve little purpose for most individuals. Despite this, they continue to emerge in many people, often leading to discomfort or complications.
When Do Wisdom Teeth Erupt?
The age at which wisdom teeth emerge can vary, but most people get their wisdom teeth between the ages of 17 and 25. Several factors can influence when wisdom teeth start to grow, including genetics, oral health, and overall development. Below is a breakdown of the typical timeline for the eruption of wisdom teeth:
1. Early Teenage Years (Around Age 12-15)
During these years, the development of wisdom teeth typically begins below the gum line. However, they are not usually visible during this stage. At this point, the teeth are still in the process of forming and may not cause any noticeable symptoms. X-rays taken during routine dental exams can help your dentist monitor the progress of your wisdom teeth development.
2. Late Teenage Years (Ages 17-18)
The most common time for wisdom teeth to start emerging is between the ages of 17 and 18. For some individuals, the teeth may begin to break through the gum line during this time, often causing discomfort or mild pain. This is typically when people experience the first noticeable symptoms related to wisdom teeth.
At this stage, wisdom teeth may either fully emerge, remain partially impacted, or become fully impacted beneath the gums. The positioning of the teeth can influence whether they cause problems or not.
3. Early 20s (Ages 19-22)
For many people, the late teenage years and early 20s are when wisdom teeth are fully formed and begin to break through the gums. Some individuals may experience symptoms such as pain, swelling, or discomfort as the teeth emerge. Others may not experience any noticeable issues, and the teeth may fully erupt without complications.
At this age, many individuals have their wisdom teeth fully erupted or may have them removed if they are causing issues such as infection, crowding, or misalignment.
4. Mid to Late 20s (Ages 23-25)
By the time a person reaches their mid-20s, their wisdom teeth may have fully erupted, remain impacted, or even stop growing altogether. In some cases, wisdom teeth that have not emerged by age 25 may not erupt at all. Some individuals may also experience problems related to their wisdom teeth even in their 20s, such as the onset of infection, gum disease, or tooth decay.
Why Do Wisdom Teeth Erupt Later in Life?
Wisdom teeth typically emerge in late adolescence or early adulthood because that is when the body has completed much of its development. As the body matures, the jaw reaches its full size and shape, which may provide enough space for the wisdom teeth to grow. Several factors contribute to the timing of wisdom teeth eruption:
1. Jaw Growth and Development
The jaw needs to fully develop before the wisdom teeth can emerge. Most people’s jaws stop growing around the age of 18, which is why wisdom teeth are usually seen during the late teenage years or early adulthood. In some people, there is not enough room in the jaw for the wisdom teeth to emerge properly.
2. Genetics
Genetics play a significant role in determining when wisdom teeth emerge. Some individuals may develop their wisdom teeth early, while others may experience delayed eruption. Additionally, the size and shape of your jaw, which are influenced by genetics, can impact the space available for wisdom teeth to grow.
3. Evolutionary Changes
As human evolution has progressed, the size of the jaw has decreased, reducing the space available for wisdom teeth. Modern diets and softer foods have also lessened the need for these teeth, which may explain why some people no longer develop wisdom teeth or have them removed when they do.
Symptoms of Wisdom Teeth Eruption
As wisdom teeth begin to emerge, they may cause discomfort, pain, or swelling. Some individuals may experience no symptoms at all, while others may encounter several signs. Here are common symptoms that people experience when their wisdom teeth are emerging:
1. Pain or Tenderness
One of the most common symptoms associated with wisdom teeth eruption is pain or tenderness in the back of the mouth. This may be due to the pressure exerted by the emerging teeth or inflammation of the gums. The pain can be mild or severe and may last for a few days to a week.
2. Swelling and Redness
As wisdom teeth break through the gum line, they may cause swelling and redness in the surrounding tissues. This is a common symptom that occurs as the gums adjust to accommodate the new teeth. In some cases, this swelling can be accompanied by a mild fever.
3. Difficulty Opening the Mouth
Some individuals experience difficulty opening their mouths fully when their wisdom teeth begin to emerge. This can be due to swelling in the gums or jaw and is often accompanied by pain.
4. Bad Taste or Odor
If wisdom teeth are partially erupted or impacted, they can create an environment where bacteria can grow. This may result in a bad taste or odor in the mouth, especially if food becomes trapped around the tooth.
5. Gum Inflammation or Infection
Partially erupted wisdom teeth can lead to inflammation or infection of the surrounding gum tissue, a condition known as pericoronitis. This can cause pain, swelling, and difficulty swallowing or speaking.
What If Wisdom Teeth Don’t Erupt?
In some cases, wisdom teeth may fail to erupt at all. This can occur if there is not enough space in the jaw, or the teeth may remain impacted beneath the gum line. If wisdom teeth do not emerge, they may not cause any symptoms, but they can still cause problems such as:
1. Impaction and Infection
If wisdom teeth remain impacted, they can lead to infections, cysts, or damage to surrounding teeth. Even if they don’t erupt, impacted wisdom teeth can still cause discomfort and require removal.
2. Dental Issues
In some cases, the lack of eruption may cause problems with adjacent teeth. If the wisdom teeth push against other teeth in the jaw, they can cause misalignment or crowding, affecting the overall bite.
When Should You See a Dentist?
If you begin to experience symptoms associated with your wisdom teeth, it is important to consult with a dentist. Your dentist can take X-rays to determine the position of your wisdom teeth and provide recommendations for care. In some cases, your dentist may suggest removing the wisdom teeth before complications arise, especially if they are causing pain, infection, or misalignment.
Conclusion
Wisdom teeth generally emerge between the ages of 17 and 25, although the exact timing can vary from person to person. Some individuals may experience no issues with their wisdom teeth, while others may face complications that require removal. Understanding the typical timeline for wisdom teeth eruption, as well as the factors that influence their growth, can help you stay informed about your oral health. If you experience pain, swelling, or other symptoms, it’s important to consult with a dentist to determine the best course of action.
