Impacted Wisdom Teeth
Wisdom teeth are the last set of molars to develop, usually appearing between the ages of 17 and 25. While some people have no issues when these teeth erupt, many experience problems because there simply is not enough room in the mouth to accommodate them properly. When this happens, a wisdom tooth may become “impacted.”
An impacted wisdom tooth is a tooth that cannot fully erupt through the gums into its normal position. It may remain trapped beneath the gum tissue, partially emerge, or grow at an angle against neighbouring teeth. Impacted wisdom teeth are extremely common and are one of the leading reasons patients are referred for oral surgery.
There are several types of impaction. A tooth may be fully impacted, meaning it remains completely below the gumline and embedded in the jawbone. It may also be partially impacted, where only part of the tooth breaks through the gums. Wisdom teeth can also grow sideways, tilt forward into the neighbouring molar, or angle backward toward the jaw.
Many impacted wisdom teeth cause symptoms such as pain, swelling, jaw stiffness, headaches, bad breath, or tenderness around the gums. In some cases, patients may not notice any symptoms at all, which is why regular dental examinations and X-rays are important. Even painless impacted teeth can create hidden problems beneath the surface.
One of the biggest concerns with impacted wisdom teeth is infection. Partially erupted teeth create small openings where bacteria and food debris can become trapped. This can lead to painful gum infections known as pericoronitis. Impacted teeth may also contribute to tooth decay, cyst formation, damage to neighbouring teeth, or crowding in the mouth.
When a dentist determines that an impacted wisdom tooth should be removed, the procedure is more involved than a standard tooth extraction. Because the tooth is often trapped beneath gum tissue or bone, a surgical extraction is required.
The process typically begins with dental X-rays to evaluate the exact position of the tooth and its proximity to nerves and surrounding structures. Local anesthetic is used to numb the area, and many patients may also choose sedation for additional comfort.
During the procedure, the dentist or oral surgeon carefully opens the gum tissue to access the impacted tooth. In some cases, a small amount of bone must be removed to expose the tooth. The wisdom tooth is often divided into smaller sections to make removal safer and less traumatic to the surrounding tissues. Once the tooth is removed, the area is cleaned and sutures may be placed to aid healing.
Recovery following impacted wisdom tooth removal usually involves mild swelling, soreness, and limited jaw movement for several days. Patients are typically advised to rest, avoid strenuous activity, eat soft foods, and carefully follow post-operative instructions to reduce the risk of complications such as dry socket or infection.
At Erbsville Dental, regular dental examinations and digital imaging help identify impacted wisdom teeth before they lead to more serious problems. Early evaluation allows patients to better understand their treatment options and maintain long-term oral health.
