Impacted Wisdom Teeth: Surgical Procedure & Cost Guide | Professional Advice from Hong Kong Dentists – 皓齒牙科醫務中心(荃灣) Starry Smile Dental Centre (Tsuen Wan)

Wisdom teeth are a common oral health issue, especially impacted wisdom teeth (teeth that fail to erupt properly). These can cause severe pain, gum inflammation, and even damage to neighboring teeth. If left untreated, impacted wisdom teeth may require surgical extraction.

This article provides a detailed breakdown of the wisdom tooth surgery process, potential risks, and cost estimates in Hong Kong, helping you prepare for the procedure.

What Are Impacted Wisdom Teeth?

Wisdom teeth are the third molars located at the very back of the mouth. Not everyone has wisdom teeth, and some may have fewer than four. Their presence and position depend on genetics.

Wisdom teeth typically emerge between ages 17-25, but due to limited jaw space, many do not erupt properly, leading to impaction.

Types of Impacted Wisdom Teeth

Horizontal impaction: The tooth grows sideways, pressing against the neighboring tooth.
Vertical impaction: The tooth remains completely buried in the gums or jawbone.
Angular impaction: The tooth grows at an angle, partially emerging from the gum.
Partial eruption: Only part of the wisdom tooth is visible, making it prone to trapping food and bacteria, leading to infection.

Common Problems Caused by Impacted Wisdom Teeth

✔ Tooth pain or swelling – Pressure on neighboring teeth or gums causes discomfort.
✔ Gum infections (pericoronitis) – Partially erupted wisdom teeth often lead to recurring gum inflammation.
✔ Cavities or gum disease – Difficult-to-clean areas lead to bacterial buildup.
✔ Damage to adjacent teeth – Wisdom teeth may push against neighboring teeth, causing misalignment or decay.

Wisdom Tooth Surgery: Step-by-Step Guide

Wisdom tooth surgery is a common dental procedure. Below is a detailed step-by-step guide, covering everything from diagnosis to post-surgery care.

1. Initial Examination & Diagnosis

✔ X-ray assessment – The dentist will take X-rays to evaluate the position, depth, and surrounding bone structure of the wisdom teeth.
✔ Dental evaluation – The dentist will determine whether removal is necessary and assess the complexity of the extraction.

📌 Tip: If you experience persistent pain or swollen gums, consult a dentist early to prevent worsening complications.

2. Pre-Surgery Preparation

✔ Medical history check – Your dentist will ask about any allergies, chronic illnesses, or medications you are taking.
✔ Local anesthesia – Most wisdom tooth surgeries are performed under local anesthesia, ensuring a painless procedure.
✔ Mental preparation – This is a routine surgery, and most patients can resume normal activities within a few days.

3. Surgical Procedure

The surgery typically takes 30 minutes to 1 hour, depending on the tooth’s position and impaction level.

1️⃣ Local Anesthesia

✔ Before starting, the dentist will inject local anesthesia to numb the area completely.
📌 Tip: You may feel pressure but no pain during the surgery.

2️⃣ Gum Incision & Bone Removal

✔ If necessary, the dentist will make a small incision in the gums to expose the tooth.
✔ If the wisdom tooth is covered by bone, a small portion of the bone may need to be removed to facilitate extraction.

3️⃣ Tooth Sectioning (If Required)

✔ For deeply impacted or large wisdom teeth, the dentist may cut the tooth into smaller sections for easier removal.

4️⃣ Tooth Extraction

✔ The dentist carefully removes the tooth using specialized tools, minimizing damage to surrounding tissues.

5️⃣ Wound Cleaning & Suturing

✔ The surgical site is cleaned, ensuring no debris or bacteria remain.
✔ Sutures may be used to aid healing and reduce bleeding.

Post-Surgery Care Instructions

Proper post-surgical care is crucial for fast recovery and avoiding complications. Follow these steps after surgery:

1. First 24 Hours

✔ Control bleeding & apply ice packs

Bite on gauze for 30-60 minutes to stop bleeding. Change it if necessary.
Apply an ice pack on the cheek for 15 minutes at a time, with 15-minute breaks, to reduce swelling.

✔ Avoid rinsing or using straws

Do not rinse your mouth for 24 hours to prevent the blood clot from dislodging (dry socket).
Avoid using straws, as suction can cause healing delays.

✔ Dietary recommendations

Stick to soft or liquid foods (e.g., porridge, soup).
Avoid hard or spicy foods that may irritate the wound.

2. First 48 Hours

✔ Gentle rinsing

Use warm salt water or an antibacterial mouthwash to keep the area clean.

✔ Avoid intense physical activity

No heavy lifting or workouts for 48 hours, as increased blood pressure may cause bleeding and swelling.

3. After One Week

✔ Wound check & suture removal

If non-dissolvable stitches were used, you’ll need a follow-up for removal in 7 days.

✔ Gradual return to a normal diet

Resume normal eating habits but avoid very hard or spicy foods until fully healed.

4. When to Seek Immediate Medical Attention

If you experience any of the following, contact your dentist immediately:
❌ Severe pain lasting over 3 days
❌ Excessive bleeding or pus formation
❌ High fever or worsening facial swelling
❌ Signs of dry socket (persistent pain due to blood clot loss)

Wisdom Tooth Surgery Risks & Prevention

Wisdom tooth surgery is generally safe, but potential risks include:

1. Dry Socket

✔ Risk: Blood clot dislodges, exposing the bone, causing intense pain.
✔ Prevention: Avoid smoking, straws, or vigorous rinsing after surgery.

2. Infection

✔ Risk: Bacterial buildup in the wound may cause swelling, pus, or fever.
✔ Prevention: Maintain good oral hygiene & take prescribed antibiotics.

3. Nerve Damage

✔ Risk: Lower wisdom teeth may be close to nerves, potentially causing temporary or permanent numbness in the lips or tongue.
✔ Prevention: X-ray assessments & choosing an experienced dentist.

4. Damage to Neighboring Teeth

✔ Risk: Poor technique may injure adjacent teeth or roots.
✔ Prevention: Careful extraction by a skilled dentist.
