Complications and Risks of Tooth Extractions: What You Need to Know

Introduction of Risks of Tooth Extractions

Tooth extractions, including the potential risks of tooth extractions, might seem like a formidable procedure, but they are routine surgeries conducted by dentists and oral surgeons. Knowing what to anticipate helps alleviate the stress associated with the experience.

Several factors may necessitate tooth extraction, including:

1. Severe tooth decay renders the tooth unrestorable.
2. Significant gum issues lead to losing supporting bone around the tooth, resulting in tooth loosening.
3. Severe local infections affecting the tooth.
4. Unsuccessful root canal treatment (endodontic treatment) despite multiple retreatment attempts.
5. A tooth that has been severely traumatized.

Additionally, even a healthy tooth may need extraction for orthodontic treatment to straighten the teeth. 

Similar to any medical procedure, tooth extractions carry potential complications, including the risks of tooth extractions such as infection, dry socket, and prolonged swelling. However, proper treatment for these risks can minimize the likelihood of further complications. The following section will explore the complications that may arise after a tooth extraction.

Categorizing Complications

Complications can be classified in various ways. They can be categorized as:

1. Pre-operative – concerns related to medical conditions or anatomy
2. Intra-operative – issues arising during the procedure
3. Post-operative – complications occurring after the procedure

Alternatively, complications may be divided according to location (local or distant), severity (minor or major), and type (general extraction complication or specific to a particular tooth).

Factors contribute to the complications of tooth extractions.

Tooth-Related Factors:

The tooth’s anatomy significantly influences the success of tooth extraction, along with the potential risks of tooth extractions. Teeth with rotated crowns, curved roots, and long and slender ones pose challenges during extraction. Additionally, heavily filled, root-treated, brittle, and extensively broken-down teeth can be difficult to extract. The hardness and thickness of the supporting bone also play a role, with teeth in hard and thick bone presenting greater extraction difficulty.

Patient-Related Factors:

1. Underlying Medical Conditions: Patients with Diabetes Mellitus (elevated glucose levels) or immunocompromised status may experience poor healing, leading to socket infections. In severe cases, the infection may spread throughout the body.
2. History of Radiotherapy or Chemotherapy: Individuals with a history of jaw radiotherapy or chemotherapy for conditions like Nasopharyngeal Carcinoma may have poorly vascularized jaws, resulting in inadequate socket healing, known as osteoradionecrosis.
3. Oral Hygiene: Proper oral hygiene maintenance is crucial during the healing period. Food particles or debris in the socket can disrupt the healing process.
4. Smoking Habit: Smoking can negatively impact wound healing by reducing blood supply to the affected area, introducing toxins, and potentially injuring the gums.

Potential Complications Following a Tooth Extraction

Tooth extractions are a routine dental procedure with generally minimal complications. However, like any medical procedure, certain risks should be acknowledged.

• Bleeding

After surgery, a certain amount of bleeding is anticipated. Minor bleeding, oozing, or redness in the saliva is not uncommon. Localized post-extraction bleeding can result from soft tissue or bone bleeding. Mild tissue bleeding may occur due to extraction-related trauma, causing injury to blood vessels (arterial, venous, or capillary). Bone or osseous bleeding can be attributed to nutrient canals or central vessel damage.

• Swelling and Inflammation

Swelling is a natural response to tooth extraction, part of the body’s healing process. Simple extractions may cause minor swelling, while complex procedures, such as removing impacted wisdom teeth or multiple extractions, can lead to significant swelling. Typically, swelling around the mouth, cheeks, eyes, and sides of the face becomes noticeable on the day following surgery. If persistent swelling or inflammation, accompanied by intense pain, occurs, contacting the dentist is advisable. In some cases, there may be a risk of infection, indicated by symptoms like a high temperature, discharge from the extraction site, and ongoing pain and swelling.

 

Around three in four (74%) of adults have had a tooth extracted. 33%. One in three (33%) of adults have never flossed or cleaned interdentally.

 

• Alveolar Osteitis (Dry Socket)

Normally, a blood clot forms in the area of tooth extraction, acting as a protective barrier for the underlying bone and nerves. Alveolar osteitis, or dry socket, is a painful condition that may occur when a blood clot fails to form, dislodges, or dissolves before the socket heals. This exposes the underlying bone and nerves, causing intense pain in the socket and along the nerves extending to the face. Inflammation and potential blockage with food debris can exacerbate the pain. Symptoms usually arise one to three days after the extraction.

• Pain

Once the anesthesia wears off, pain, especially in the extracted tooth area, is expected. Pain from more complex procedures may persist longer and require regular analgesic management. If discomfort persists or worsens, patients should promptly contact their dentist for an examination to rule out any pathological conditions.

• Fracture

During tooth extraction, it’s not uncommon for the tooth to break, which is generally inconsequential since the intention is to extract it. However, if a tooth fragment is unintentionally left behind, it can lead to an infection or cyst in the future. Additionally, there’s a risk of accidental damage to nearby healthy teeth if they come into contact with the tools or the extracted tooth.

The dentist must apply the right amount of pressure when extracting a tooth. Sufficient pressure is necessary for complete tooth removal, but excessive force can result in the fracture of the jawbone. This risk is more pronounced in individuals with a weakened jawbone due to factors such as age or gum disease. Your dentist can assess whether you are susceptible to a jaw fracture. Regrettably, there isn’t a foolproof method to prevent fractures except for maintaining the strength of your jawbone.

Risks of Tooth Extractions: When to Reach Out to Your Dentist?

It is normal to encounter some discomfort once the anesthesia wears off. Expect mild swelling and residual bleeding during the initial twenty-four hours following a tooth extraction. Nevertheless, if bleeding or pain persists for more than four hours post-extraction, indicating potential risks of tooth extractions, it is advisable to contact your dentist. For indications of severe complications, immediate contact with the dental office is essential. The following outlines severe risks that may arise after tooth extractions:

1. Prolonged bleeding lasting beyond 12 hours.
2. The presence of a high fever and chills signal a potential infection.
3. Episodes of nausea or vomiting.
4. Persistent coughing.
5. Experiencing chest pain.
6. Possibility of a jaw fracture.
7. Shortness of breath.
8. Continuous swelling, accompanied by redness or pus at the surgical site.
9. Persistent numbness.
10. Damage to adjacent teeth neighbouring the extracted area.
11. Development of a sinus hole in cases where the extracted tooth is positioned in the upper back of the mouth.
