Impacted Wisdom Tooth Extraction

An impacted wisdom tooth has not erupted fully into a normal, functional position and may remain partly or completely covered by gum or bone. Surgical removal may be considered when impaction is associated with pain, repeated infection, decay, gum disease, cystic change, or damage to the neighbouring second molar.

At Bourgeois Dental Clinic in Dubai, the dentist evaluates the type and depth of impaction, root anatomy, surrounding bone, second-molar health, nerve or sinus proximity, medical history, and whether monitoring or surgical treatment is more appropriate.

What Types of Wisdom Tooth Impaction Can Occur?

• Soft-tissue impaction: The crown is covered mainly by gum tissue.
• Partial bony impaction: Part of the tooth is covered by jawbone.
• Complete bony impaction: The tooth remains fully within the jawbone.
• Mesioangular impaction: The tooth tilts toward the second molar.
• Horizontal impaction: The tooth lies sideways.
• Vertical impaction: The tooth is upright but unable to erupt normally.
• Distoangular impaction: The tooth tilts toward the back of the jaw.

Does Every Impacted Wisdom Tooth Need Removal?

No. An impacted tooth may be monitored when it is disease-free, not damaging neighbouring structures, and can be reviewed appropriately.

Removal may be considered when the risks of keeping the tooth are greater than the surgical risks.

When May Surgical Removal Be Recommended?

• Repeated infection or pericoronitis
• Persistent pain or swelling
• Decay in the impacted tooth
• Decay or root damage in the second molar
• Periodontal pocketing or bone loss behind the second molar
• A cystic or pathological change
• Food trapping and poor cleaning access
• Impaction interfering with selected dental treatment
• Progressive disease detected on imaging

What Happens During Assessment?

The dentist evaluates:

1. Symptoms and infection: Pain, swelling, drainage, bad taste, fever, and mouth-opening limitation.
2. Impaction type: Direction, depth, bone coverage, and gum coverage.
3. Second-molar health: Decay, root damage, gum pockets, and bone support.
4. Root development and anatomy: Number, curvature, length, and separation.
5. Nerve relationship: Proximity of lower-tooth roots to the mandibular nerve canal.
6. Sinus relationship: Proximity of upper-tooth roots to the maxillary sinus.
7. Medical and medication risks: Bleeding, infection, anaesthesia, and healing considerations.

When Is Three-Dimensional Imaging Considered?

Three-dimensional imaging may be recommended when standard imaging suggests close nerve proximity, unusual root anatomy, a deeply positioned tooth, a lesion, or complex surrounding anatomy.

It helps clarify relationships but cannot remove surgical risk completely.

How Is an Impacted Wisdom Tooth Removed?

1. Local anaesthesia: The tooth, gum, and surrounding tissues are numbed.
2. Gum access: A controlled opening is made to expose the tooth.
3. Bone removal: A limited amount of bone may be removed to gain safe access.
4. Tooth sectioning: The crown or roots may be divided into smaller sections.
5. Controlled removal: The sections are removed while limiting force on neighbouring structures.
6. Socket cleaning: Infected or pathological tissue is removed when necessary.
7. Bone smoothing: Sharp or irregular bone may be adjusted.
8. Sutures: The gum is repositioned and closed when required.
9. Aftercare: Instructions are provided for bleeding, swelling, cleaning, diet, and warning signs.

Why Is the Tooth Divided into Sections?

Sectioning can reduce the amount of bone removal and limit pressure on the second molar, jawbone, nerves, and other surrounding structures.

It is often a planned surgical technique rather than a complication.

What Is the Risk to the Lower-Jaw Nerve?

Lower impacted wisdom teeth may lie close to the nerve that supplies sensation to the lower lip and chin. A separate nearby nerve supplies sensation and taste to part of the tongue.

Nerve irritation may cause temporary altered sensation and, less commonly, persistent changes. The degree of risk depends on anatomy and cannot be eliminated entirely.

Can an Alternative to Full Removal Be Considered?

In selected lower wisdom teeth with close nerve proximity, an alternative procedure that removes the crown while leaving suitable roots may be discussed where clinically appropriate.

This is not suitable for every case and retained roots require monitoring because later infection, migration, or additional treatment may occur.

What Is the Sinus Risk for Upper Impacted Wisdom Teeth?

Upper wisdom tooth roots may be close to the maxillary sinus. Removal can occasionally create a communication between the mouth and sinus.

Patients may receive instructions to avoid forceful nose blowing, sneezing with the mouth closed, or pressure changes during healing.

What Are the Possible Risks?

• Pain, swelling, bruising, or bleeding
• Infection
• Dry socket
• Delayed healing
• Jaw stiffness
• Root fracture or retained fragment
• Damage to the second molar or its restoration
• Nerve irritation or altered sensation
• Sinus communication
• Bone fracture in uncommon complex cases
• Need for additional surgery
• Persistence or recurrence of symptoms

How Should You Prepare?

• Provide a complete medical and medication history
• Follow clinic instructions about eating before treatment
• Arrange transportation when advised
• Avoid smoking
• Prepare soft foods and cold packs
• Plan time for recovery based on procedure complexity
• Discuss travel, exercise, work, and medication requirements

What Is Normal After Surgery?

Temporary pain, swelling, bruising, limited mouth opening, mild bleeding, and chewing discomfort may occur. Swelling may change during the first several days before gradually improving.

How Should You Care for the Site?

• Bite on gauze as instructed
• Use cold packs when recommended
• Take medication only as prescribed or advised
• Eat soft foods
• Avoid smoking and tobacco
• Avoid forceful rinsing during early healing
• Clean the mouth gently
• Do not pull the cheek repeatedly to inspect the wound
• Attend review or suture-removal appointments

When Should You Contact the Clinic?

Contact the clinic for persistent bleeding, increasing swelling, fever, pus, worsening pain after initial improvement, concerning numbness, wound opening, persistent unpleasant taste, or increasing difficulty opening the mouth.

Difficulty breathing or swallowing, rapidly spreading facial or neck swelling, swelling near the eye, confusion, severe weakness, or uncontrolled bleeding requires urgent medical assessment.
