Wisdom teeth removal is one of the most common dental procedures. Whether you're experiencing symptoms or your dentist has recommended extraction, this guide explains everything you need to know about the process.
What Are Wisdom Teeth?
Wisdom teeth are the third set of molars that typically emerge between ages 17 and 25—hence the name, as this is supposedly the age of wisdom. Most people develop four wisdom teeth, though some have fewer or none at all.
Our ancestors needed these extra molars to chew tough, uncooked foods. Today, with smaller jaws and softer diets, wisdom teeth often don't have enough room to emerge properly.
Why Do Wisdom Teeth Need Removal?
Not all wisdom teeth require removal. However, extraction is often recommended when:
- Impaction: The tooth is trapped under the gum or bone and can't emerge properly
- Partial emergence: Creates a hard-to-clean area that traps bacteria
- Crowding: Pushing against other teeth, causing misalignment
- Infection: Pericoronitis (infection of gum tissue around the tooth)
- Cysts or tumours: Can develop around impacted teeth
- Decay: Difficult positioning makes them hard to clean
- Gum disease: Increased risk due to cleaning difficulties
Signs Your Wisdom Teeth May Need Attention
- Pain or tenderness at the back of your mouth
- Swelling around the jaw
- Red, swollen, or bleeding gums near the back teeth
- Difficulty opening your mouth
- Bad breath or unpleasant taste
- Headaches or earaches
- Visible partial eruption of teeth
The Removal Procedure
Before Surgery
Your dentist will take X-rays to assess the position of your wisdom teeth. You'll discuss anaesthesia options—local anaesthesia numbs the area while you remain awake, while sedation or general anaesthesia may be recommended for complex cases.
Before surgery:
- Arrange for someone to drive you home
- Follow fasting instructions if receiving sedation
- Inform your dentist of any medications you're taking
- Wear comfortable, loose-fitting clothing
During Surgery
The procedure typically takes 30-60 minutes. For simple extractions, the tooth is loosened and removed with forceps. For impacted teeth, an incision is made in the gum, and sometimes bone is removed to access the tooth. The tooth may be sectioned for easier removal.
After Surgery
Recovery typically takes 3-7 days. Follow these guidelines:
- First 24 hours: Bite on gauze to control bleeding, apply ice packs, rest with head elevated
- Pain management: Take prescribed or over-the-counter pain relief as directed
- Diet: Stick to soft foods—yoghurt, soup, mashed potatoes. Avoid hot foods initially
- Oral hygiene: Don't rinse for 24 hours. Then rinse gently with salt water after meals
- Avoid: Drinking through straws, smoking, spitting forcefully (can dislodge the blood clot)
- Activities: Rest for 1-2 days, avoid strenuous exercise for a week
Potential Complications
While complications are rare, be aware of:
- Dry socket: When the blood clot dislodges, exposing bone. Very painful, but treatable
- Infection: Signs include fever, increased swelling, pus, or worsening pain after a few days
- Nerve damage: Rare, but can cause numbness in lip, tongue, or chin (usually temporary)
- Prolonged bleeding: Some bleeding is normal; persistent heavy bleeding is not
