wisdom teeth


Wisdom teeth, also known as third molars, are the last set of teeth to emerge, typically appearing in late adolescence or early adulthood. While some people may experience no issues with their wisdom teeth, many face complications due to their late arrival and limited space in the mouth. These problems can lead to discomfort, infection, and other dental issues if not addressed promptly. 

In this blog, we’ll discuss these topics:

Wisdom Teeth: What Are They?

Most people have four wisdom teeth, one in each corner of the mouth. They typically emerge in late adolescence or early adulthood, around ages 17 to 25.

While they can be beneficial for chewing if they align properly, many people experience issues because there often isn’t enough space in the mouth to accommodate them. This can lead to impaction, misalignment, crowding, or other dental problems. In such cases, dentists often recommend their removal to prevent complications.

How Come They’ve Named Wisdom Teeth?

Wisdom teeth got their name because they typically appear when people are older and supposedly wiser, usually in their late teens or early twenties. This age is associated with increased maturity, hence the term “wisdom.”

Common Issues with Wisdom Teeth

Wisdom teeth, also known as third molars, typically emerge in late adolescence or early adulthood. They often cause various issues due to their late emergence and limited space in the mouth. Here are some common problems associated with wisdom teeth

1. Impaction

  • Description: Wisdom teeth may become impacted if there isn’t enough room for them to emerge properly. They can be trapped within the jawbone or gums.
  • Types:
    • Fully impacted: Completely stuck within the jawbone.
    • Partially impacted: Partially emerges but can’t fully break through the gums.

2. Crowding

  • Description: Emerging wisdom teeth can push against other teeth, causing crowding or shifting of the existing teeth.
  • Impact: This can affect alignment and may require orthodontic treatment.

3. Cysts and Tumors

  • Description: A sac filled with fluid, called a cyst, can form around the impacted wisdom tooth. Rarely, these cysts can lead to tumors.
  • Impact: This can damage the jawbone, teeth, and nerves.

4. Tooth Decay

  • Description: Partially emerged wisdom teeth create spaces that are hard to clean, making them prone to cavities.
  • Impact: Leads to tooth decay and gum disease.

5. Gum Disease

  • Description: Partially erupted wisdom teeth can create pockets in the gums where bacteria can grow.
  • Impact: This can lead to gum inflammation and infection (pericoronitis).

6. Alignment Issues

  • Description: The pressure from emerging wisdom teeth can alter the alignment of teeth.
  • Impact: This can undo orthodontic work or cause new alignment problems.

7. Pain and Discomfort

  • Description: Pain is a common issue, often due to pressure on adjacent teeth, infections, or cysts.
  • Impact: Can cause significant discomfort and interfere with daily activities.

8. Sinus Problems

  • Description: Upper wisdom teeth are close to the sinuses, and their roots can affect sinus cavities.
  • Impact: This can cause sinus pain, pressure, and congestion.
Symptoms of Problematic Wisdom Teeth

Symptoms of Problematic Wisdom Teeth

Recognizing the symptoms of problematic wisdom teeth is important for timely intervention and treatment. Here are some common symptoms to watch for

1. Pain and Discomfort

  • Location: Pain at the back of the mouth, behind the molars.
  • Description: This can be a constant dull ache or sharp pain that comes and goes.

2. Swelling and Redness

  • Gums: Swollen, red, or tender gums around the wisdom teeth.
  • Face: Swelling in the jaw or cheeks.

3. Bad Breath

  • Cause: Bacteria accumulating around partially erupted teeth can cause persistent bad breath (halitosis).

4. Difficulty Opening the Mouth

  • Description: Limited ability to open the mouth due to swelling or pain in the jaw muscles.

5. Unpleasant Taste

  • Cause: Infection or food particles trapped around the wisdom teeth can cause a foul taste in the mouth.

6. Headaches

  • Cause: Pressure and misalignment from impacted wisdom teeth can lead to tension headaches.

7. Stiff Jaw

  • Description: Jaw stiffness or difficulty moving the jaw.

8. Infection Signs

  • Symptoms: Fever, swollen lymph nodes, and pus around the affected area.

9. Crowding and Shifting of Teeth

  • Description: Noticeable changes in the alignment of teeth, often causing discomfort.

10. Sinus Issues

  • Symptoms: Sinus pain, pressure, congestion, and frequent sinus infections, especially with upper wisdom teeth.

Treatment and Extraction of Wisdom Teeth Issues

Treatment and extraction of problematic wisdom teeth depend on the severity of the issues and the symptoms experienced. Here’s an overview of common treatments and the extraction process:

Non-Surgical Treatments

Pain Relief

  • Over-the-counter Medications: Ibuprofen or acetaminophen can help alleviate pain and reduce inflammation.
  • Prescriptions: For severe pain, a dentist may prescribe stronger pain relievers.


  • Usage: Prescribed if there’s an infection around the wisdom teeth.
  • Duration: Typically taken for a course of 7-10 days to clear the infection.

Mouth Rinses

  • Salt Water Rinse: Helps reduce inflammation and cleanse the area.
  • Antibacterial Mouthwash: Can help reduce bacteria and prevent infection.

Surgical Treatments

Pre-Surgery Preparation

  • Consultation: Initial visit with an oral surgeon or dentist to discuss symptoms, review x-rays, and plan the extraction.
  • Medical History: Providing a comprehensive medical history, including any medications being taken.
  • Instructions: Pre-surgery instructions, such as fasting before surgery, if general anesthesia is used.


  • Local Anesthesia: Numbs the specific area where the tooth will be removed.
  • Sedation Anesthesia: Administered through an intravenous (IV) line to calm the patient.
  • General Anesthesia: Patient is made unconscious during the procedure.

Extraction Procedure

  • Incision: A small incision is made in the gum to expose the tooth and bone.
  • Bone Removal: Sometimes a small amount of bone around the tooth needs to be removed.
  • Tooth Sectioning: The tooth may be divided into sections to make removal easier.
  • Extraction: The tooth is gently extracted from its socket.
  • Stitches: The incision may be closed with stitches to aid healing.

Post-Surgery Care

  • Pain Management: Prescribed painkillers or over-the-counter pain relievers.
  • Swelling Reduction: Applying ice packs to the outside of the cheek intermittently.
  • Rest and Recovery: Resting for at least 24 hours and gradually resuming normal activities.
  • Diet: Eating soft foods and avoiding hard, crunchy, or spicy foods.
  • Oral Hygiene: Keeping the mouth clean with gentle brushing and rinsing with salt water.


  • Post-operative Check: Follow-up appointment to monitor healing and remove any stitches if necessary.
  • Complications: Monitoring for signs of complications such as dry socket, infection, or excessive bleeding.

Alternative Treatments

  • Coronectomy: Partial removal of the tooth’s crown, leaving the roots in place, sometimes recommended if the roots are too close to nerves.

Potential Complications

  • Dry Socket: A painful condition that occurs if the blood clot at the site of extraction is dislodged.
  • Infection: Signs include fever, severe pain, pus, or swelling.
  • Nerve Damage: Rarely, damage to the inferior alveolar nerve can cause numbness or tingling in the lip, tongue, or chin.

Recovery Tips

  • Hydration: Drink plenty of water, avoiding alcohol, caffeine, and hot beverages.
  • Activity: Limit physical activity to avoid dislodging the blood clot.
  • Smoking: Avoid smoking as it can delay healing and increase the risk of complications.
Preventive Care
