Wisdom teeth, also known as third molars, are the last set of molars to emerge in the back of the mouth. Many individuals wonder if these teeth continue to grow throughout life, often due to discomfort or changes in the mouth. This article clarifies the developmental patterns of wisdom teeth and addresses perceptions surrounding their ongoing growth.
The Typical Journey of Wisdom Teeth
Wisdom teeth begin forming deep within the jawbone during childhood, often around ages 7 to 10. Full development and eruption of these teeth occur later, typically between 17 and 25. They are the last teeth to emerge into the oral cavity.
Once a wisdom tooth has fully formed and erupted, its physical size does not continue to increase. The “growth” refers to their initial development within the jaw and subsequent movement through the gum line. This eruption process can span months or years as the tooth slowly breaks through and settles into place.
Understanding Apparent Continued Growth
While wisdom teeth do not physically grow larger after initial formation, the perception of continued growth can arise from several factors. A tooth can continue to erupt over a prolonged period, sometimes even later in life, especially if it was previously impacted or only partially emerged. This delayed or extended eruption can create the sensation that the tooth is still developing.
Changes in the surrounding oral environment also contribute to this perception. The gums around a wisdom tooth can become inflamed or swollen, which might be mistaken for the tooth getting bigger. Shifting of adjacent teeth or changes in jawbone structure can also put pressure on wisdom teeth, making them feel more prominent or causing new discomfort. These dynamic changes, rather than an increase in tooth size, often explain the feeling of ongoing growth.
Common Problems Associated with Wisdom Teeth
The unique position and late eruption of wisdom teeth often lead to various issues, which can contribute to the belief that they are causing new problems. One common issue is impaction, where the tooth does not fully erupt and remains trapped within the jawbone or gums, often growing at an awkward angle. This can lead to pain, swelling, and damage to nearby teeth.
Infections, such as pericoronitis, can develop around partially erupted wisdom teeth because food particles and bacteria easily get trapped under the gum flap, an area difficult to clean. This can cause pain, swelling, and bad breath. Fluid-filled sacs called cysts can also form around impacted wisdom teeth, potentially damaging the jawbone or nerves. These problems can manifest years after initial eruption, leading people to think their wisdom teeth are “growing” or developing new issues.
When to Consult a Dentist
Seeking professional dental advice is important if any concerns arise regarding wisdom teeth. If pain, swelling, or tenderness occurs in the back of the mouth, it is advisable to consult a dentist. Other signs that warrant a visit include difficulty opening the mouth, persistent bad breath, or an unpleasant taste.
Regular dental check-ups are beneficial for monitoring the development and position of wisdom teeth, even if no immediate problems are present. Dentists can use X-rays to assess the teeth’s status and determine if any intervention, such as monitoring, cleaning, or extraction, might be necessary to prevent future complications. Early assessment can often simplify any required treatment.
