Wisdom Tooth Inflammation: Cleaning, Care & Extraction Options

Why do wisdom teeth swell and ache, and when is removal needed? We cover the common causes, warning symptoms and treatment options for wisdom tooth pain.

The impact of wisdom tooth inflammation can vary greatly. Some people believe that if the inflammation doesn't last long and the symptoms are mild, they can let wisdom tooth pain naturally subside. Others may experience such severe pain due to wisdom tooth inflammation that it keeps them awake at night. So, why do we experience wisdom tooth pain? And, how should we generally address the issue of wisdom tooth swelling and pain? In this article by Home Dental, we'll answer your questions about wisdom teeth!

This page focuses on causes and how to manage wisdom-tooth inflammation. If your main symptoms are throat pain on swallowing, bad breath, or difficulty opening the mouth, start with Wisdom Tooth Inflammation Symptoms; the general symptom checklist below still applies to common gum swelling and toothache.

Common Causes of Wisdom Tooth Pain

In general, the causes of wisdom tooth pain can be roughly categorized based on the stage of wisdom tooth growth.

During Wisdom Tooth Eruption

Due to the limited oral space in modern individuals, the emergence of a wisdom tooth can create a sensation of pressure in the mouth. It may even lead to swelling and pain in the gums surrounding the emerging wisdom tooth. If your wisdom tooth happens to exert pressure on the roots of adjacent teeth and nerves, it can result in more severe discomfort.

After Wisdom Tooth Growth

Once wisdom teeth have fully emerged, upper jaw wisdom teeth may come into contact with the lower jaw gums during biting, potentially leading to ulcers. Additionally, wisdom teeth are generally challenging to clean, increasing the likelihood of tooth decay. If food remnants get trapped in the gum flaps, it can also give rise to gum diseases such as pericoronitis.

Wisdom teeth problems that cannot be ignored - Impacted Wisdom Teeth

The cause of impacted wisdom teeth is typically related to congenital jawbone development. Due to the shorter jawbones in modern humans, wisdom teeth often lack adequate space to fully emerge. Consequently, they may become partially or entirely embedded within the jawbone, under the gums, or even grow horizontally.

On the other hand, modern dietary habits have reduced the need for chewing raw foods. This diminished stimulation for jawbone growth has resulted in insufficient space within the jaw for proper wisdom tooth emergence.

When wisdom teeth grow horizontally or become impacted, they exert pressure on nearby second molars. In milder cases, this can facilitate the impaction of food debris and the buildup of dental plaque, ultimately causing tooth decay. In more severe instances, it can lead to inflammation of the periodontal tissues, placing additional stress on adjacent teeth and potentially causing the recession of their tooth roots.

Neglecting impacted wisdom teeth in a timely manner can allow wisdom tooth inflammation to progress into more severe conditions. For example, wisdom tooth cysts may displace wisdom teeth from their original positions, erode bone, absorb adjacent tooth roots, and in extreme cases, lead to jawbone fractures. Consequently, addressing the issue of impacted wisdom teeth is of utmost importance.

Wisdom Teeth Symptoms

How can we identify symptoms related to wisdom teeth? They can be broadly categorized into general symptoms and symptoms arising from wisdom tooth inflammation.

General Symptoms:

- Redness of the gums adjacent to the second molars
- Persistent swelling around the wisdom teeth
- Gum inflammation
- Toothache

Symptoms of wisdom tooth inflammation:

- Swelling and pain in the submandibular lymph nodes

- Difficulty in opening the mouth and swallowing

- Fever

- Headache

Tooth pain originates from the trigeminal nerve. If you're experiencing pain in the rear teeth, it may not necessarily be the wisdom tooth itself that's causing the pain initially; however, wisdom tooth-related headaches can be more pronounced. If you exhibit any of the aforementioned symptoms stemming from wisdom tooth inflammation, we strongly recommend seeking medical attention promptly to prevent the condition from progressing into a more severe cellulitis.

Does Wisdom Tooth Inflammation Require Treatment?

Similar to general inflammation, the approach to dealing with wisdom tooth inflammation varies depending on its severity.

If you can ensure that your oral hygiene is maintained and the inflammation of your wisdom teeth is mild, it is possible for the inflammation to naturally resolve. If there is no pain, you can continue to observe the situation and emergency treatment may not be necessary.

However, if the inflammation is severe, you experience intense pain, the gums remain swollen for an extended period, and there is pus, it is crucial to seek immediate medical attention and consider the removal of wisdom teeth to prevent future issues. Otherwise, worsening inflammation in wisdom teeth may not only endanger the health of adjacent teeth but also impact your daily life, diet, and appearance.

Wisdom Tooth Pain Treatment

Wisdom tooth pain requires timely professional treatment
When faced with wisdom tooth pain, we can effectively address the issue through the following emergency and long-term treatment methods.

Emergency Measures

If you only experience intermittent and bearable pain, you can take painkillers or antibiotics to alleviate the inflammation.

If the swelling and pain from wisdom teeth persist, rinsing your mouth with saline can help relieve symptoms.

If you experience wisdom tooth pain 2-3 times within a year, and the pain or swelling becomes more pronounced, we recommend a long-term approach.

Long-term Solution

After analysis with professional equipment and assessment by a professional dentist, you may be advised to have your wisdom teeth removed to prevent recurring swelling, pain, and inflammation.

Wisdom tooth removal is categorized as non-surgical and surgical:

Non-surgical:  In non-surgical wisdom tooth treatment, the dentist typically removes the entire tooth from the mouth using dental tools, under local anesthesia.

Surgical:Generally, this is performed when wisdom teeth's growth positions are complicated, impacted wisdom teeth are present, or wisdom teeth are close to nerves. The dentist will administer local anesthesia around the mouth and gums. Since impacted wisdom teeth are generally not on the surface of the gums, the gums need to be incised and lifted during the operation to remove the bone and gum that hinder the growth of the wisdom teeth. Then, the wisdom tooth is sectioned into several parts to ensure that the entire wisdom tooth is removed with minimal trauma. Finally, the wound is cleaned and sutured to stop bleeding and speed up healing.

Precautions for Wisdom Tooth Surgery

Preoperative Precautions - Seek Early Medical Attention

When wisdom tooth pain is particularly severe, especially during acute inflammation, the tooth and the surrounding tissues become more sensitive. It may require a higher dosage of local anesthesia to achieve numbness, and in some cases, there might still be sensations during the extraction. Therefore, when you experience wisdom tooth pain, it's crucial not to delay seeking treatment until the last moment for wisdom tooth extraction. Instead, early intervention is advisable.

Preoperative Assessment

Before the surgery, a comprehensive assessment is necessary to ensure that the inflammation of the wisdom teeth is not in the acute stage, preventing oral bacteria from infecting other organs through the bloodstream and causing complications. Thus, it's essential to consult a certified, professional, and experienced dentist for wisdom tooth removal. This helps avoid extensive surgical wounds or excessively long operation times, which could otherwise hinder the recovery process.

Since the growth of wisdom teeth varies from person to person, including differences in tooth position, depth of impaction, growth angle, and the severity of inflammation and pain, it's recommended to discuss the expected postoperative outcomes and care instructions with the dentist before the actual surgery.

Postoperative Precautions

Stopping Bleeding and Avoiding Touching the Wound

After wisdom tooth surgery, it's essential to follow the dentist's instructions for stopping bleeding. This may involve biting down on gauze for approximately half an hour. Avoid touching the wound inside your mouth with your tongue or fingers. On the day after the surgery, it's best to refrain from gargling or brushing your teeth. Consult your dentist to understand when you can safely use a toothbrush for oral care after the surgery.

Pain Management

It's normal to experience swelling and pain after the anesthesia wears off post-surgery. Within 24 hours of the operation, you can alleviate pain and facial swelling by applying ice packs or taking painkillers as directed by your dentist. If the pain persists, seek medical attention again to check for any signs of wound inflammation.

Diet and Physical Activity

After surgery, avoid consuming foods that are difficult to chew, and refrain from smoking or drinking alcohol. Additionally, on the day of the surgery, do not engage in vigorous physical activity or overexert yourself.

The inflammation and pain symptoms caused by wisdom teeth can be unbearable. In case you experience any of the aforementioned wisdom tooth symptoms, it's crucial to seek medical attention promptly. Avoid waiting until the last minute to address wisdom tooth problems and aim to resolve your toothache as soon as possible!

FAQ

Frequently Asked Questions

  • Why do wisdom teeth cause pain?

    Wisdom tooth pain typically occurs during eruption when limited jaw space creates pressure, or after growth when they're difficult to clean and prone to decay. Impacted wisdom teeth that grow horizontally can press on adjacent teeth and nerves, causing more severe discomfort. If you're experiencing persistent pain, we recommend a clinical assessment to determine the cause.

  • How much does wisdom tooth removal cost?

    Wisdom tooth removal is priced by case: non-surgical extraction from HK$3,500; surgical extraction — for impacted or horizontally positioned teeth requiring flap raising or tooth sectioning — from HK$6,000. Specialist or complex cases are charged according to the treating dentist's qualifications, and fees are higher when a specialist takes the case. After clinical and X-ray assessment, we explain the fee components clearly, and treatment starts only with your consent. The first general consultation is HK$180. We provide a personalised quote after examining your X-rays and assessing the surgical approach needed. Quality differences lie in pre-surgical X-ray planning of root form and nerve distance, with sectioned removal along the root path causing less trauma than forced whole-tooth extraction. WhatsApp us to arrange a consultation.

  • What are the signs that my wisdom tooth needs urgent treatment?

    Seek immediate attention if you experience swollen lymph nodes under your jaw, difficulty opening your mouth or swallowing, fever, or severe headaches. These symptoms indicate wisdom tooth inflammation that could progress to cellulitis if left untreated. Persistent swelling, redness around the second molars, or ongoing toothache also warrant a professional assessment.

  • How long does wisdom tooth removal take?

    A straightforward extraction of a fully erupted wisdom tooth typically takes 20 to 30 minutes. Impacted or horizontally positioned wisdom teeth require surgical removal, which may take 45 minutes to an hour depending on complexity. Your dentist will explain the expected procedure time after reviewing your X-rays during the consultation.

  • What are the risks of leaving an impacted wisdom tooth untreated?

    Untreated impacted wisdom teeth can trap food debris and plaque, leading to decay in adjacent second molars. In severe cases, they may cause periodontal inflammation, root resorption of neighbouring teeth, wisdom tooth cysts that erode bone, or even jawbone fractures. We recommend addressing impacted wisdom teeth promptly to prevent these complications.

  • Can wisdom tooth pain go away on its own?

    Mild inflammation may temporarily subside, but the underlying issue—limited space, impaction, or difficult cleaning—remains. Without proper treatment, symptoms often recur and worsen over time. If you're experiencing wisdom tooth pain, a clinical assessment helps determine whether monitoring or extraction is the safer long-term approach.
