Delaying wisdom tooth extraction for 4 years: Unforeseeable consequences and lessons learned from a clinical case at Herident.

Wisdom teeth—the last molars to erupt—are often the “root cause” of various oral health issues. However, many people choose to delay treatment, resulting in serious consequences. The story of Mr. N.H.Đ, a patient at Herident, clearly illustrates the potential risks of postponing wisdom tooth extraction at the right time. 

Customer Case at Herident: Delaying Wisdom Tooth Extraction for 4 Years 

Initial Condition of the Patient

Mr. N.H.Đ, 26 years old, visited Herident with existing oral health concerns. Although he was aware of his condition, he had delayed treatment for years. 

Initial Diagnosis:

Through clinical examination and X-rays, doctors diagnosed him with serious complications caused by postponing wisdom tooth extraction. Specifically:

• Teeth 38 and 48 were impacted, causing complications 
• Teeth 18 and 28 were tilted toward the cheek

Examination and Treatment Process at Herident

Wisdom tooth extraction is performed according to a standardized procedure to ensure maximum safety and effectiveness for the patient.

1. Examination and Consultation

• Initial clinical assessment: A general evaluation of the patient’s oral condition and wisdom tooth positions was performed. In this case, the patient had all four third molars. Teeth 38 and 48 were mesioangularly impacted, while teeth 18 and 28 lacked occlusal contact and were over-erupted, causing food impaction and hygiene difficulties.
• The patient was given a panoramic X-ray to determine tooth angulation, jawbone condition, and the impact of the wisdom teeth. 

On the panoramic film, teeth 38 and 48 were located close to the mandibular nerve canal. However, as the panoramic film is only 2D and the nerve canal borders appeared visible, the doctor ordered a CBCT scan to ensure safety by visualizing the relationship between the tooth roots and the mandibular nerve in 3D.

Tooth 38 had two curved roots, was not in contact with the nerve canal, but was tilted mesially at a 70-degree angle, impinging on the distal cervical area of tooth 37 and causing deep caries near the pulp.

Teeth 48 was mesioangularly impacted at an angle of 47.78 degrees, with two curved, hook-shaped roots, close to the mandibular nerve canal, and showed bone loss on the distal side of teeth 47.

• Based on clinical and paraclinical examinations, the doctor indicated the extraction of all four wisdom teeth, with the extraction plan divided into two sessions:

Session 1: Extract tooth 28 and 38. After about 2–3 weeks of healing, proceed to restore tooth 37 with deep caries at the distal cervical area.

Session 2: Extract tooth 18 and 48.

As the patient was afraid of swelling and pain during wisdom tooth extraction, in this case, the doctor used the extraction method combined with piezotome to reduce trauma and postoperative swelling.

2. Pre-extraction preparation

• The patient received scaling and was instructed on oral hygiene before the extraction.
• Next, the patient underwent a pre-procedure checklist, including allergy history and checking vital signs (pulse, blood pressure, etc.).
• Once ready, the wisdom tooth extraction procedure was carried out.

3. Wisdom tooth extraction procedure

In this case, the doctor used ultrasonic waves to sever the ligament around the tooth to reduce trauma and help the patient minimize postoperative swelling and pain. The tooth was tilted nearly 60 degrees, with a contact point against tooth number 7. Therefore, the doctor planned to section the crown and root, release the impaction point, and limit bone removal to preserve as much bone as possible. The piezotome was used at this stage to extract the curved roots close to the nerve canal without causing trauma, ensuring absolute safety for the patient.

The extraction proceeded smoothly, and the entire process took 30 minutes. The patient was very comfortable throughout the extraction.

• After the extraction, the doctor sutured the wound to promote healing and prevent bleeding or infection.
• The patient was instructed to bite on gauze for 30–60 minutes to stop the bleeding.

5. Post-extraction instructions

• The doctor prescribed painkillers, anti-inflammatory medications, and antibiotics.
• Provided oral hygiene guidance, dietary advice, and precautions to avoid complications such as infection.
• Scheduled a follow-up appointment after 3 days to check the wound and monitor healing.

• Treatment result: After 3 days, the patient came in for the follow-up. Upon examination, the doctor observed that the patient was recovering very well, with no swelling or pain, and was eating and functioning normally.

In-Depth Analysis of the Consequences of Delaying Wisdom Tooth Extraction

Signs That Indicate a Wisdom Tooth Needs Extraction

• Recurring Pain:Persistent pain in the posterior jaw (wisdom tooth area), accompanied by limited mouth opening, may subside after a few days or develop pus. These symptoms often recur and can lead to other conditions like pharyngitis or gastrointestinal inflammation due to the frequent swallowing of pus from the inflamed tissue surrounding the tooth.
• Swollen Gums or Infection:Red, swollen, or tender gums around the wisdom tooth, often seen when the tooth is erupting. Most common in cases where the tooth erupts under a gum flap.
• Difficulty Opening the Mouth: Limited mouth opening or jaw stiffness may indicate a serious infection caused by the wisdom tooth, leading to trismus.
• Cavities in the Wisdom Tooth:Due to their hard-to-clean position, wisdom teeth are prone to decay and may also trap food, leading to decay in adjacent teeth.
• Bad Breath and Bitter Taste in the Mouth: These signs often occur when food debris or bacteria accumulate around the wisdom tooth.
• Pressure on Adjacent Teeth: If nearby teeth feel sore, displaced, or loose, it could be due to a mesioangularly impacted wisdom tooth causing bone loss and pushing against tooth 7.

Consequences of Not Removing a Wisdom Tooth in Time

Benefits of Early Extraction:

Early management of wisdom teeth offers numerous benefits—not only does it help you avoid uncomfortable pain, but it also effectively protects and maintains your oral health: 

• Prevent Serious Complications: Impacted or misaligned wisdom teeth can cause infections, tooth decay, abscesses, and even damage adjacent teeth. Early removal prevents these issues before they escalate and potentially threaten overall health.
• Preserve Oral Health: Timely extraction reduces pressure on the dental arch, prevents crowding and misalignment, and protects the integrity of your teeth and jaw.
• Save Time and Costs: Complications caused by wisdom teeth often require complex and costly treatments. Early intervention helps you avoid unexpected expenses and prolonged recovery.
• Protect General Health: Chronic oral infections may impact overall health and increase the risk of systemic conditions such as arthritis, cardiovascular disease, or widespread infection.
• Faster Recovery: Extracting wisdom teeth before complications arise usually involves a simpler procedure, less pain, and quicker healing than treating advanced cases.

Taking early action not only protects your oral health but also contributes to your overall well-being, comfort, and confidence in daily life.

Serious Consequences If Wisdom Teeth Are Not Extracted 

 Impacted or Embedded Wisdom Teeth

• These teeth often lack space to erupt properly, leading to misalignment, horizontal eruption, or impaction under the gums.
• .Persistent Pain Caused by pressure on the gums or adjacent teeth; accompanied byswollen, inflamed gums..
•   Damage to Adjacent Teeth (Tooth 7): Can cause pain, looseness, or cavities in the neighboring molars.
• Tooth Decay: Wisdom teeth are hard to clean, making them a breeding ground for bacteria and leading to decay.: Răng khôn thường mọc ở vị trí khó vệ sinh, dễ tích tụ vi khuẩn, gây sâu răng.

        Pericoronitis (Inflammation Around a Partially Erupted Wisdom Tooth)

• Wisdom teeth that do not fully erupt often cause gum flaps that cover the tooth.
• Symptoms include:
  • Pain and swelling
  • Difficulty opening the mouth and bad breath
  • In severe cases, the infection can spread to surrounding areas

Tooth Misalignment on the Dental Arch

• Crowded or impacted wisdom teeth may push other teeth out of place, disrupting the bite.
• Can cause difficulty chewing or speaking.

Cyst Formation or Jawbone Resorption

• Impacted wisdom teeth may develop A cyst .
• If untreated, the cyst may:
  • Destroy surrounding bone tissue
  • Weaken jaw structure and increase the risk of jaw fractures

 Impact on Overall Health

• Infections from wisdom teeth can spread, causing sepsis,lymphadenitis, or cellulitis in the maxillofacial region.
• Causes fever, fatigue, and more serious complications if not treated.
