Wisdom Teeth Evaluation & Assessment in Beaverton

We begin with a CBCT three-dimensional scan of your jaw, which takes about 15 seconds. Our team then reviews the images with you, showing the exact position, angulation, and root development of each wisdom tooth. He assesses the relationship to the inferior alveolar nerve, the condition of adjacent teeth, and any signs of cyst formation or bone loss. You leave with a clear recommendation: extract now, extract later, or monitor with periodic imaging.

We recommend an initial wisdom teeth evaluation between ages 16 and 19. At this stage, the roots are typically one-half to two-thirds formed, making extraction easier and recovery faster if needed. However, wisdom teeth can and should be evaluated at any age if symptoms develop, if a general dentist identifies a concern on X-ray, or if no prior assessment has been done.

A panoramic X-ray is a two-dimensional image that flattens three-dimensional structures, which can make the nerve canal appear closer to or farther from the roots than it actually is. CBCT produces a full three-dimensional volume that allows us to measure nerve-to-root distance precisely, identify root curvature in all planes, and detect cyst formation that may be hidden on a flat image. For surgical planning, CBCT is the definitive diagnostic tool.

Impaction is diagnosed when CBCT imaging shows that a wisdom tooth cannot erupt into its normal functional position due to physical obstruction by adjacent teeth, bone, or soft tissue. We classify impaction by angulation (mesioangular, distoangular, horizontal, or vertical) and by depth (soft tissue impacted, partial bony, or full bony). Each classification carries different surgical implications and risk levels.

Yes, in some cases. If a wisdom tooth is fully erupted, properly aligned, free of decay, not causing periodontal problems on the adjacent tooth, and can be adequately cleaned, monitoring may be appropriate. We also monitor deeply impacted teeth in older adults when the risk of surgical complications outweighs the risk of leaving the tooth. Monitoring requires periodic imaging to watch for cyst development or changes in position.

Common signs include recurring pain or swelling in the back of the jaw, difficulty opening your mouth fully, swollen or bleeding gums behind your last molar, bad taste or odor from the area, headaches or ear pain on one side, and visible decay or food trapping around a partially erupted tooth. However, many problematic wisdom teeth produce no symptoms at all, which is why imaging-based evaluation is essential.

Pericoronitis is an infection of the gum tissue (operculum) that partially covers a wisdom tooth that has not fully erupted. Food and bacteria become trapped beneath this flap of tissue, causing inflammation, pain, swelling, and sometimes pus drainage. Recurrent pericoronitis is one of the strongest indications for wisdom tooth extraction because the condition will continue to recur as long as the operculum remains.

Absolutely. A mesioangularly impacted wisdom tooth presses against the distal root of the second molar, and over time this pressure can cause external root resorption of the adjacent tooth. We also see cavities develop on the distal surface of the second molar where the impacted wisdom tooth creates a food-trapping pocket that is impossible to clean. Both of these complications are identifiable on CBCT before they become advanced.

Not at all. The evaluation consists of a CBCT scan, which takes about 15 seconds and involves no discomfort, followed by a clinical examination of the area. There are no needles, no anesthesia, and no surgical intervention during the evaluation visit. If extraction is recommended, that is scheduled as a separate appointment with appropriate anesthesia and sedation options.

The inferior alveolar nerve runs through a canal in the mandible directly beneath the roots of lower wisdom teeth. When CBCT shows root tips in close proximity to or in contact with this canal, there is an improved risk of nerve injury during extraction that could cause temporary or permanent numbness of the lower lip and chin. Identifying this relationship before surgery allows our team to modify the surgical technique or recommend a coronectomy to protect the nerve.

No referral is required. You can call our Beaverton office directly at (503) 822-0096 to schedule a wisdom teeth evaluation. Many patients come to us after their general dentist identifies a concern on a routine X-ray, but self-referral is equally welcome. We coordinate findings with your general dentist if you have one.

A dentigerous cyst forms from the follicular sac that surrounds the crown of an unerupted tooth. Fluid accumulates within this sac, creating a slowly expanding cyst that destroys surrounding bone. The incidence is relatively low — approximately 1-3% of impacted wisdom teeth — but because these cysts grow silently without symptoms, they can become quite large before detection. This is a key reason we recommend periodic imaging for retained impacted wisdom teeth even when you feel no discomfort.

The evaluation fee includes the CBCT scan and our team’s clinical assessment. Most dental insurance plans cover diagnostic imaging and consultations. Our front desk verifies your benefits before the visit and provides a cost estimate. If extraction is recommended, a separate treatment estimate with insurance pre-authorization is prepared so you know your out-of-pocket costs before scheduling surgery.

In most cases, earlier extraction produces better outcomes. Younger patients have less dense bone, incompletely formed roots, and faster healing capacity. Waiting until a wisdom tooth causes pain, infection, or damage to the adjacent tooth means the surgery is often more complex, the recovery is longer, and the adjacent tooth may already be compromised. The purpose of the evaluation is to determine the right timing for your specific situation based on anatomy, not symptoms.

This is one of the most debated topics in dentistry. Current evidence suggests that wisdom teeth exert some forward pressure but are unlikely to be the sole cause of anterior crowding, which is influenced more by growth patterns and the natural mesial drift of teeth over time. That said, orthodontists frequently request wisdom teeth removal before or during orthodontic treatment to eliminate a potential variable. During your evaluation, we discuss this specific question if orthodontic alignment is a concern.
