Do I Need to Have My Wisdom Teeth Removed?

February 1, 2024

Determining whether to undergo wisdom teeth extractions in Richmond Hill, ON, can be crucial for many. Wisdom teeth, also called the third molars, are the last ones to emerge. While some people never experience issues with them, others may require wisdom teeth removal for various reasons. This comprehensive guide aims to help you understand the various aspects of this dental procedure with insights from Mackenzie Smiles Dentistry.

Signs and Symptoms That Indicates the Need for Wisdom Tooth Removal

Jaw Pain and Stiffness: Often overlooked, a stiff or sore jaw can signal the need for wisdom teeth removal. This discomfort can extend to the temporomandibular joint, causing difficulties opening and closing the mouth and impacting daily activities like talking and eating.

Sinus Issues: Surprisingly, problems with wisdom teeth can affect your sinuses. The roots of the upper wisdom teeth are located near the sinus cavities, and their development or impaction can lead to sinus pain, pressure, and congestion.

Cyst Formation: Although less common, cysts or fluid-filled sacs can develop around the impacted wisdom teeth. These cysts can damage the jawbone, teeth, and nerves left untreated.

Repeated Infection of Soft Tissue: Occasional infections behind the lower last tooth can be a sign. These infections, caused by trapped food and bacteria, can lead to painful, recurrent swelling.

Altered Taste or Bad Breath: Impacted wisdom teeth can create areas where food particles and bacteria accumulate, leading to an unpleasant taste or persistent bad breath despite regular brushing and mouthwash use.

Overcrowding or Misalignment: In some cases, emerging wisdom teeth can push other teeth, causing misalignment or overcrowding, which might necessitate orthodontic treatments if not addressed.

Chronic Headaches: The pressure from growing wisdom teeth can sometimes lead to headaches. The pain can radiate from the jaw to the sides of the head, causing discomfort throughout the day.

Awareness of these symptoms can help make a timely decision about wisdom teeth removal, thereby preventing more serious complications. It's always advisable to consult with a dental professional upon experiencing any of these symptoms to get a proper evaluation and discuss potential treatment options.

Risks and Complications of Keeping Impacted Wisdom Teeth

Retaining impacted wisdom teeth should not be taken lightly, as it can lead to several complications affecting oral health and overall well-being.

Infection: The most common issue arising from impacted wisdom teeth is infection. This occurs when food particles and bacteria get trapped around the impacted tooth, leading to painful, swollen gums and potentially serious infections that can spread to other areas of the mouth or body. Persistent infections cause discomfort and can weaken the body's immune response.

Damage to Adjacent Teeth: When a wisdom tooth grows at an angle, it can push against neighboring teeth. This pressure can cause misalignment of your teeth, leading to bite issues and discomfort. Over time, this misalignment can wear down the enamel, leading to cavities and decay, not just in the wisdom teeth but also in the adjacent teeth.

Cysts and Tumors: In rare cases, cysts or tumors may develop around an impacted wisdom tooth. These growths can cause significant damage to the jawbone and nerves. In severe cases, this might necessitate more extensive surgical procedures, beyond a standard emergency wisdom tooth extraction, to remove the cysts or tumors and repair the jawbone.

Gum Disease: Impacted wisdom teeth are challenging to clean due to their location in the back of the mouth. This can lead to a buildup of plaque and tartar, increasing the risk of periodontal (gum) disease. Gum disease is not only painful but can also lead to tooth loss and has been linked to other health issues such as heart disease and diabetes.

Tooth Decay: Partially erupted wisdom teeth can create pockets where bacteria thrive, leading to tooth decay. Decay in wisdom teeth can be challenging to treat due to their location and can easily spread to adjacent teeth.

Jaw Problems: In some cases, cysts associated with impacted wisdom teeth can grow large enough to hollow out the jaw and cause a fracture. Additionally, the ongoing pressure from impacted teeth can lead to chronic jaw pain or temporomandibular joint (TMJ) disorders, manifesting as pain in the jaw joint, difficulty opening the mouth, and a clicking or grinding noise when the jaw is moved.

Overall Health Concerns: It's important to remember that oral health significantly impacts overall health. Issues stemming from impacted wisdom teeth, like infection or gum disease, can contribute to broader health concerns, especially if pre-existing conditions make you more susceptible to infections.

Benefits of Removing Wisdom Teeth

Removing wisdom teeth prevents overcrowding and maintains the alignment of your existing teeth. This is especially significant for those who have undergone orthodontic treatments like braces, as impacted wisdom teeth can negate the results of these treatments by causing misalignment.

Regarding oral health, wisdom teeth removal significantly reduces the risk of decay and gum disease. These third molars are often hard to reach with a toothbrush or floss, making them hotspots for plaque and bacteria accumulation. Removing them, you can maintain better oral hygiene, ensuring the back of your mouth is as clean and healthy as the rest.

Furthermore, impacted wisdom teeth can create pockets between the teeth where food and debris collect, leading to infection and inflammation. Removing these teeth eliminates these pockets, reducing the risk of periodontal disease, which can have long-term effects on oral health.

Alternatives to Wisdom Tooth Removal

Regular Monitoring: Some opt for regular dental check-ups to monitor their wisdom teeth.

Improved Oral Hygiene: Rigorous cleaning can sometimes manage minor symptoms.

Minor Surgical Procedures: In certain cases, small procedures can address issues without full removal.

Factors to Consider Before Making a Decision

Several factors should be considered when deciding whether wisdom teeth removal is the right course of action. This decision is about immediate relief and long-term oral health and well-being.

Age and Health: It's well-known that younger patients typically recover faster from surgeries, including wisdom teeth extractions. Their bodies are more resilient, and the risk of complications is generally lower. However, older patients can still undergo this procedure. For them, a thorough health assessment is crucial to ensure they're fit for surgery and to anticipate any special care they might need during recovery.

Severity of Impaction: The degree of impaction plays a significant role in this decision. Wisdom teeth can be fully erupted, partially erupted, or completely impacted. Partially or fully impacted teeth are more likely to cause problems as they can grow at an angle, potentially causing pain, infection, and damage to adjacent teeth. In such cases, removal is often recommended to prevent future complications.

Long-Term Oral Health Goals: Considering how wisdom teeth might affect your future dental health is essential. Impacted wisdom teeth can be a breeding ground for bacteria and may lead to more serious dental issues like decay or gum disease. If left untreated, these issues can have a domino effect, leading to further oral health problems. On the other hand, if your wisdom teeth are healthy, fully grown, positioned correctly, and not causing any pain or dental issues, they can be left in place.

Pre-Operative Procedures and Preparation

Consultation and X-rays: A comprehensive dental examination is essential before wisdom teeth removal. This includes detailed X-rays, which give your dentist a clear view of the position of your wisdom teeth, other teeth, and the nerves in your jaw. This step is crucial in planning a safe and effective removal procedure, as it helps identify any potential complexities that might affect the surgery.

Discussing Anesthesia Options: Your dentist will discuss anesthesia options during your consultation. The type of anesthesia used can vary from local anesthesia, which numbs the area around your wisdom teeth, to general anesthesia, where you'll be asleep during the procedure. Understanding the risks and benefits of each type of sedation is crucial, as it affects your surgery experience and recovery process. Your overall health and the complexity of the extraction will guide this decision.

Preparing for Recovery: Preparing for post-operative care is as important as the surgery itself. It's advisable to arrange for someone to drive you home after the procedure, especially if you'll be receiving general anesthesia. It would help if you also took some time off from work or school to allow your body to heal. Stocking up on soft foods and pain management supplies is recommended. Additionally, your dentist might advise you to avoid certain activities and foods that could disrupt the healing process.

Wisdom Tooth Removal Procedure

The wisdom tooth removal procedure is a surgical process that requires precision and care. Initially, the area around the wisdom tooth is numbed with local anesthesia to ensure the patient's comfort during the procedure. In some cases, sedation may be used, especially for patients experiencing anxiety or undergoing multiple extractions at once.

Once the area is numbed, the dentist or oral surgeon makes an incision in the gum tissue to expose the tooth and bone. If the wisdom tooth is impacted – meaning it's covered by bone – a small amount of bone might need to be removed to access it. This is done with specialized dental tools designed to minimize trauma to the surrounding area.

The surgeon may cut it into smaller sections in severe impaction or if the tooth is particularly large. This technique makes removing the tooth piece by piece easier and helps reduce the amount of force needed, minimizing the impact on surrounding tissues. This step-by-step approach is crucial for minimizing discomfort and aiding a smoother recovery process.

After removing the tooth, the surgeon thoroughly cleans the site to remove any debris or remaining tooth fragments. This cleaning is vital to prevent infection and promote healing. The gum is then sutured closed, usually with dissolvable stitches that disappear as the healing progresses.

Potential Complications After Wisdom Tooth Removal

Dry Socket: This condition, known medically as alveolar osteitis, occurs in a small percentage of cases. It's more likely if you smoke, don't follow post-operative care instructions, or have a history of dry sockets with previous dental extractions. Symptoms usually include severe pain within a few days after surgery, often accompanied by a foul odor or taste in the mouth. Treatment involves cleaning the socket, placing a medicated dressing, and managing pain.

Infection: The infection risk is always there in any surgical procedure. Signs of infection include fever, increased swelling, persistent pain, and pus from the extraction site. Maintaining good oral hygiene and following the prescribed course of antibiotics, if given, are vital steps to prevent infection. In some cases, additional treatment might be needed to manage the infection.

Nerve Damage: While rare, nerve damage can occur, especially if the wisdom teeth are deeply rooted or near nerves. This might result in temporary or, in very rare cases, permanent numbness or altered sensation. Symptoms often include a tingling or lack of sensation in the lips, chin, and sometimes the tongue. Most nerve damage heals over time, but in cases where it persists, further treatment or therapy may be necessary.

Bleeding and Swelling: Some bleeding is normal, but excessive bleeding can be a concern. Similarly, while some swelling is expected, it should diminish after a few days. If these symptoms persist or worsen, it could indicate a complication.

Difficulty in Jaw Movement: Some patients may experience trismus or limited jaw movement after wisdom tooth extraction. This usually resolves on its own but can be uncomfortable in the meantime.

Improper Healing: In some cases, the extraction site may not heal properly, leading to a 'bone sequestrum,' where a small piece of bone remains after surgery. This can cause ongoing pain and may require additional dental procedures.
