Wisdom teeth removal, a common dental procedure performed to alleviate pain and prevent dental issues, is generally considered safe and routine. However, like any surgical procedure, it carries potential risks and complications that patients should be aware of. Understanding these risks is essential for making informed decisions and ensuring a smooth recovery.
Introduction to Wisdom Teeth Removal
Wisdom teeth, also known as third molars, typically erupt in late adolescence or early adulthood. Due to their late eruption and often awkward positioning, they can cause various dental problems such as impaction, crowding, and infections.
Wisdom teeth removal is often recommended to prevent these issues and maintain oral health.
Surgical Risks And Complications
Infection
Description: Infection is one of the most common complications following wisdom teeth removal. It can occur if bacteria enter the surgical site before or after the extraction.
Symptoms: Symptoms include increased pain, swelling, redness, and possibly fever.
Management: Treatment involves antibiotics and sometimes drainage of the infected area.

Damage to Adjacent Teeth And Structures
Description: During the extraction process, adjacent teeth, gums, or even nerves can sustain damage, especially if the wisdom teeth are impacted or in close proximity to other structures.
Symptoms: Symptoms may include pain, sensitivity, or in severe cases, loosening or fracture of adjacent teeth.
Management: Repair or stabilization of the affected structures may be necessary, possibly requiring additional dental procedures.
Nerve Injury
Description: Wisdom teeth removal, particularly in the lower jaw, carries a risk of nerve injury. The inferior alveolar nerve, which runs near the lower wisdom teeth, can be bruised, stretched, or in rare cases, permanently damaged.
Symptoms: Patients may experience numbness, tingling, or altered sensation in the lips, tongue, or chin.
Management: Monitoring and reassurance are often sufficient for mild cases. Severe cases may require referral to a specialist for further evaluation and management.
Sinus Complications
Description: Upper wisdom teeth, particularly those in close proximity to the sinus cavity, can sometimes lead to sinus complications during or after extraction.
Symptoms: Symptoms may include sinus pain, congestion, or in rare cases, sinus infection (sinusitis).
Management: Proper surgical technique and post-operative care minimize this risk. Treatment, if needed, involves managing sinus symptoms and possibly antibiotics for infection.
Anesthesia Complications
Description: Although rare, complications related to anesthesia can occur during wisdom teeth removal. These may include adverse reactions to medications, respiratory issues, or in very rare cases, anaphylaxis.
Symptoms: Symptoms can vary widely depending on the specific complication but may include dizziness, nausea, difficulty breathing, or loss of consciousness.
Management: Immediate medical intervention is necessary in case of severe reactions. Proper pre-operative assessment and monitoring help mitigate these risks.
Post-operative Complications
Pain and Swelling
Description: Pain and swelling are common after wisdom teeth removal, typically peaking within the first 48 hours.
Symptoms: Mild to moderate discomfort, swelling of the cheeks or jaw.
Management: Pain medications, ice packs, and following post-operative care instructions help manage these symptoms.
Bleeding
Description: Some bleeding is normal immediately after surgery.
However, excessive or prolonged bleeding may indicate complications such as poor clot formation or injury to blood vessels.
Symptoms: Persistent bleeding, blood in saliva, or needing to change gauze pads frequently.
Management: Applying pressure to the extraction site, avoiding strenuous activity, and if necessary, seeking dental or medical attention.
Dry Socket
Description: Dry socket (alveolar osteitis) occurs when the blood clot that forms in the extraction site becomes dislodged or dissolves prematurely.
Symptoms: Intense throbbing pain, bad breath, and visible bone in the socket.
Management: Treatment involves cleaning the socket, applying medicated dressings, and pain management. Patients are advised to avoid smoking and using straws to reduce the risk.
Delayed Healing
Description: Factors such as smoking, poor oral hygiene, or underlying medical conditions can delay the normal healing process after wisdom teeth removal.
Symptoms: Prolonged pain, swelling, or difficulty opening the mouth beyond the expected recovery period.
Management: Addressing underlying causes, maintaining good oral hygiene, and following up with the dentist or oral surgeon as needed.
Jaw Stiffness And Limited Mouth Opening
Description: After surgery, some patients may experience temporary stiffness in the jaw muscles or difficulty fully opening the mouth.
Symptoms: Mild to moderate limitation in mouth opening, discomfort when chewing or talking.
Management: Gentle jaw exercises, applying warm compresses, and avoiding excessive jaw movement help alleviate symptoms.
Rare but Serious Complications
Osteomyelitis
Description: Osteomyelitis is a rare but serious infection of the bone, which can occur if bacteria enter the extraction site and spread to the underlying jawbone.
Symptoms: Severe pain, swelling, fever, and possibly pus discharge from the extraction site.
Management: Immediate medical attention is required, often involving antibiotics and sometimes surgical intervention to drain the infection.
Anaphylaxis
Description: Anaphylaxis is a severe allergic reaction that can occur in response to medications used during surgery or anesthesia.
Symptoms: Rapid onset of symptoms such as difficulty breathing, swelling of the throat or tongue, and a drop in blood pressure.
Management: Immediate administration of epinephrine (adrenaline) and emergency medical care are essential to manage anaphylactic shock.
Cardiac Events
Description: Patients with underlying cardiac conditions may be at a slightly increased risk of cardiac events during wisdom teeth removal, particularly if sedation or general anesthesia is used.
Symptoms: Symptoms can vary widely depending on the specific cardiac issue but may include chest pain, palpitations, or shortness of breath.
Management: Pre-operative cardiac evaluation and monitoring during surgery help mitigate this risk. Immediate intervention may be needed if cardiac symptoms occur.
Conclusion
While the vast majority of wisdom teeth removal procedures are completed without significant complications, understanding the potential risks and complications is crucial for both patients and dental professionals. Dentists and oral surgeons prioritize patient safety through thorough pre-operative assessments, meticulous surgical techniques, and comprehensive post-operative care instructions. Patients play an active role in their recovery by following these instructions, attending follow-up appointments, and promptly reporting any unusual symptoms or concerns to their dental care team.
By being well-informed about what can potentially go wrong during wisdom teeth removal, patients can approach the procedure with confidence and take proactive steps to minimize risks and optimize their oral health outcomes. Through careful planning, skilled execution, and attentive post-operative care, dental professionals strive to ensure a safe and successful experience for every patient undergoing wisdom teeth removal.
