Wisdom teeth, also known as third molars, are the last teeth to erupt in the mouth, usually between the ages of 17 and 25. Sometimes, however, these teeth become impacted, meaning they're unable to fully erupt through the gum line. A complete bony impaction signifies that the wisdom tooth is completely encased in bone, hidden beneath the gum tissue and fully covered by bone. This presents unique challenges compared to partially impacted wisdom teeth. This comprehensive guide will explore complete bony impactions, addressing common questions and concerns.
What is a Complete Bony Impaction of a Wisdom Tooth?
A complete bony impaction means your wisdom tooth is entirely surrounded by bone and gum tissue, preventing it from erupting into the mouth. It's essentially trapped beneath the surface. This differs from a partial impaction, where a portion of the tooth might be visible or partially erupted. Imaging techniques like panoramic X-rays are essential for accurate diagnosis of the impaction type and degree.
What are the Signs and Symptoms of a Completely Impacted Wisdom Tooth?
Often, a completely impacted wisdom tooth causes no noticeable symptoms. The problem is usually discovered during a routine dental check-up with a panoramic X-ray. However, some individuals may experience:
- Swelling or pain in the jaw: This can occur due to inflammation or infection around the impacted tooth.
- Jaw stiffness: Difficulty opening or closing the mouth might be experienced.
- Referred pain: Pain might be felt in other areas of the face or head.
- Infection (pericoronitis): The gum tissue overlying the impacted tooth can become infected, leading to pain, swelling, and pus formation. This is more common with partially impacted teeth, but can still occur with completely impacted teeth if bacteria infiltrate.
Why is it Important to Remove Completely Impacted Wisdom Teeth?
While asymptomatic, complete bony impactions can pose several risks:
- Cysts or tumors: Impacted teeth can sometimes lead to the development of benign cysts or, less frequently, tumors around the tooth's root. These need monitoring and may require removal.
- Infection: Even completely covered teeth can become infected, requiring antibiotics or surgical intervention.
- Damage to adjacent teeth: The pressure from an impacted wisdom tooth can damage the roots of the adjacent molar.
- Decay in nearby teeth: Impacted teeth can be difficult to clean, increasing the risk of decay in surrounding teeth.
- Gum disease: Impacted wisdom teeth can contribute to gum disease.
- Crowding or misalignment of teeth: Though less likely with complete impactions that haven't erupted partially, the pressure from the developing tooth may still cause subtle shifts later in life.
What are the Treatment Options for Completely Impacted Wisdom Teeth?
The primary treatment for a complete bony impaction is usually surgical removal (extraction). This procedure is typically performed by an oral surgeon under local anesthesia or sedation. The bone needs to be carefully removed to access and extract the impacted tooth.
What Does Wisdom Tooth Removal Involve?
The procedure involves making an incision in the gum tissue to expose the bone surrounding the impacted tooth. The bone is then carefully removed using specialized dental instruments, allowing the surgeon to extract the tooth. Stitches are often used to close the incision. Post-operative care involves pain management, keeping the area clean, and following the surgeon's instructions meticulously.
How Long Does it Take to Recover from Wisdom Tooth Removal?
Recovery time varies depending on the complexity of the extraction. Most people experience some swelling, pain, and discomfort for several days. A soft food diet is usually recommended initially. Full recovery typically takes several weeks. The surgeon will provide detailed post-operative instructions to ensure proper healing.
What are the Potential Risks and Complications of Wisdom Tooth Removal?
As with any surgical procedure, there are potential risks and complications associated with wisdom tooth removal. These include:
- Dry socket: A painful condition where the blood clot fails to form properly at the extraction site.
- Infection: Although rare with proper post-operative care, infection is always a possibility.
- Nerve damage: While uncommon, damage to the nerves in the jaw can occur, potentially resulting in numbness or altered sensation in the lip, chin, or tongue. The likelihood is higher with lower wisdom teeth near the inferior alveolar nerve.
- Bleeding: Excessive bleeding is rare but possible.
Does Insurance Cover Wisdom Tooth Extraction?
Most dental insurance plans cover at least part of the cost of wisdom tooth extraction, particularly if there's a clear medical necessity, such as preventing potential complications. Checking your specific plan's coverage is important.

Always consult with a qualified dentist or oral surgeon to discuss your specific situation and determine the best course of action for your complete bony impaction wisdom teeth. Remember, early intervention often minimizes complications.
