Impacted Wisdom Tooth

The most common signs and symptoms of impacted wisdom teeth include:

• Pain or discomfort
• Swelling
• Red or bleeding gums
• Jaw stiffness
• Bad breath
• Difficulty opening the mouth
• Headache
• Ear pain
• Unpleasant taste or odor in the mouth
• Swollen lymph nodes

Impacted teeth can create hard-to-reach areas in the mouth, increasing the risk of plaque buildup, cavities, and gum infections. Proper oral hygiene is essential to prevent complications and maintain oral health.

The primary cause of impacted wisdom teeth is evolutionary changes in the human jaw structure.

Over time, as our diets have evolved and dental hygiene practices have improved, the size of the human jaw has become smaller.

This reduction in jaw size often leads to insufficient space for the third molars, or wisdom teeth, to emerge properly.

As a result, the wisdom teeth can become impacted. Here are some specific factors and causes:

• Angulation of the tooth
• Late eruption
• Crowded teeth
• Soft tissue obstruction

The causes and risk factors for impacted wisdom teeth are related but not identical. Common risk factors include:

• Jaw Size: Individuals with smaller jaw sizes may have less space for the wisdom teeth to properly emerge, increasing the risk of impaction. Factors that affect jaw size include:
  • Feeding habits in infancy
  • Childhood habits like thumb sucking
  • Cross-breeding
  • High sugar consumption
• Age: Wisdom teeth typically begin to emerge in the late teens or early twenties. The age at which the teeth start to come in can influence the likelihood of impaction.
• Poor Dental Hygiene: Inadequate oral hygiene can lead to gum disease and infections, which may affect the proper eruption of wisdom teeth.
• Previous Extractions: If you have had other teeth extracted, it might alter the alignment of the remaining teeth, impacting the eruption of wisdom teeth.
• Genetics: Having a family history of impacted teeth can increase your chances of getting impacted wisdom teeth.

Diagnosis of an impacted wisdom tooth typically involves the following:

1. Clinical Examination

A dentist or oral surgeon will begin by conducting a thorough clinical examination of the mouth, teeth, and surrounding tissues. They will assess for signs and symptoms associated with impacted wisdom teeth, such as pain, swelling, redness, difficulty opening the mouth, and evidence of infection.

2. Imaging Tests

X-rays: Dental X-rays, including TMJ X-rays or periapical X-rays, help assess the position, angulation, and proximity of wisdom teeth to other teeth, and detect issues like cysts or abscesses.

CBCT Scan: A cone-beam computed tomography (CBCT) scan may be recommended for detailed 3D imaging of an impacted tooth and surrounding structures, aiding in precise treatment planning for complex cases.

The impaction of wisdom teeth cannot always be prevented, as it often depends on factors like genetics, jaw size, and tooth alignment.

However, maintaining good oral hygiene and regular dental check-ups can help monitor wisdom tooth development and address potential issues early.

Early removal of wisdom teeth showing signs of misalignment or lack of space in the jaw may prevent complications associated with impaction.

The treatment of an impacted wisdom tooth depends on various factors, including the severity of impaction, symptoms, and the individual's overall oral health. Here are common treatment options:

1. Observation

   In cases where the impacted wisdom tooth is not causing any symptoms, the dentist may recommend a wait-and-see approach. Regular monitoring through dental check-ups and X-rays can help track any changes in the condition of the impacted tooth.

2. Extraction

   The most common treatment for an impacted wisdom tooth is surgical extraction. This involves removing the impacted tooth surgically under local anesthesia or sedation. Depending on the position and complexity of the impaction, the dentist or oral surgeon may need to perform a simple extraction or a more complex surgical extraction.

3. Preventive Extraction

   Some dentists may recommend preventive extraction of impacted wisdom teeth, even if they are not currently causing symptoms. This proactive approach helps prevent potential future problems such as infection, damage to neighboring teeth, gum disease, and cyst formation.

4. Medications

   Antibiotics: If an impacted wisdom tooth shows signs of infection or inflammation, antibiotics may be prescribed to manage symptoms temporarily. Commonly used ones include:

   • Amoxicillin
   • Clindamycin
   • Metronidazole

   Analgesics (Pain relief): Over-the-counter pain medications may be recommended to manage pain and discomfort associated with an impacted wisdom tooth. Common options include:

   • Ibuprofen
   • Paracetamol
5. Other Procedures

   Operculectomy: If a wisdom tooth is partially erupted but blocked by thick gum tissue, this procedure removes the tissue to help the tooth erupt. If the tooth still doesn't emerge fully, removal might be needed.

   Autogenous Transplantation: Third molars can be moved to another site, such as a missing first molar's spot. However, this is rarely done due to a low success rate, except in special cases.

   Orthodontically Guided Eruption: This technique uses braces to help impacted teeth, such as canines or premolars, move into the correct position in the dental arch.

   Eruption-Activating Procedures: These methods are applied to developing teeth to encourage their eruption into the correct position.

Home remedies can help alleviate discomfort associated with impacted wisdom teeth temporarily, but it is important to consult a dentist and get the right treatment. Here are some home remedies that may provide relief:

• Saltwater rinse: Gargling with warm saltwater can help reduce inflammation and alleviate pain associated with an impacted wisdom tooth.

How To Do It? Mix half a teaspoon of salt in a glass of warm water and rinse your mouth thoroughly several times a day.

• Cold compress: Applying a cold compress or ice pack to the outside of the cheek near the affected area can help reduce swelling and numb the pain.

How To Do It? Wrap an ice pack in a cloth and apply it to the affected cheek for 15-20 minutes, repeating every few hours to reduce pain and swelling.

• Soft Diet: Stick to a soft diet consisting of foods that are easy to chew and swallow to avoid putting pressure on the impacted tooth. Some examples include soups, yogurt, smoothies, and fresh fruit juices.
• Clove (Laung) Oil: Clove oil contains eugenol, a natural anesthetic that can help numb the area and reduce pain.

How To Use It? Apply a small amount of clove oil to a cotton swab and dab it onto the gums near the impacted tooth.

• Peppermint: Peppermint has natural anti-inflammatory properties that can help treat gum inflammation.

How To Use It? Brew a cup of peppermint tea or use peppermint oil as mouthwash and gargle your mouth with it.

Impacted wisdom teeth can lead to various complications, and if left untreated, these issues can become more severe. Common complications of impacted wisdom teeth include:

• Pericoronitis: Inflammation of the soft tissues surrounding a partially erupted or impacted tooth, commonly a wisdom tooth. It occurs when food debris, plaque, or bacteria get trapped under the gum flap, leading to infection.
• Gum disease (Periodontitis): Impacted wisdom teeth can create pockets where bacteria accumulate, leading to inflammation of the gums.
• Cysts and tumors: Impacted wisdom teeth can lead to the formation of cysts (fluid-filled cavities) or tumors around the impacted tooth, which can damage surrounding bone and tissues.
• Damage to adjacent teeth: Wisdom teeth may push against adjacent teeth as they try to emerge, causing misalignment or damage to nearby teeth.
• Abscess formation: Untreated infections around impacted teeth can lead to the formation of abscesses, which are pockets of pus.
• Sinus issues: Impacted upper wisdom teeth can sometimes affect the sinus cavity, leading to sinus pain, pressure, or infections.
• Difficulty in cleaning: Proper oral hygiene around impacted wisdom teeth can be challenging, increasing the risk of decay and infection.
• Speech and chewing problems: Impacted wisdom teeth can cause discomfort and difficulty in speaking or chewing.

If you are experiencing any of these issues, it is advisable to have the impacted wisdom tooth removed.

Living with impacted wisdom teeth can be challenging due to the potential for discomfort, pain, and the risk of complications.

You can try the home remedies mentioned in the above section to get some relief.
