October 12, 2023 0 By contentwriter

One of the common concerns many people encounter post-dental procedures is complications arising from the healing process. An especially prevalent issue is the infected gum after wisdom tooth removal. This topic warrants special attention, given the potential repercussions of untreated infections.

This article will uncover the reasons behind these infections, shed light on early warning signs, and discuss methods to address and prevent them. Understanding potential post-operative complications is paramount if you’ve recently had a wisdom tooth extraction or are scheduled for one.

Symptoms of wisdom teeth infection

Wisdom teeth, also known as third molars, often emerge during late adolescence or early adulthood. While many people may have their wisdom tooth extraction without issues, some might experience complications, particularly infections.

Such infections can cause significant discomfort and have potential health implications if not addressed timely. Recognizing the symptoms of a wisdom teeth infection is crucial for prompt dental treatment and preventing further complications.

Symptoms of Wisdom Teeth Infection:

  1. Pain and Swelling: One of the most common symptoms is a persistent, throbbing pain around the impacted tooth, often accompanied by gum swelling.
  2. Red or Tender Gums: The gums surrounding the emerging or impacted wisdom tooth can become inflamed, tender to touch, and appear redder than usual.
  3. Bad Breath: An unpleasant odor from the mouth, even after brushing or using mouthwash, can indicate an infection.
  4. Unpleasant Taste: Some individuals report a persistent bad taste in their mouth, often resulting from pus emanating from the infected site.
  5. Difficulty in Opening Mouth: In severe cases, the infection can lead to trismus, where individuals find it challenging to open their mouth due to pain or muscle spasms.
  6. Fever and Malaise: Symptoms like elevated body temperature and feeling unwell can accompany localized symptoms.
  7. Lymph Node Swelling: In response to the infection, lymph nodes under the jaw or neck may become enlarged and tender.
  8. Difficulty Swallowing: The swelling and pain might interfere with the swallowing mechanism, causing discomfort when eating or drinking.
  9. Pus Formation: In some cases, pus might be visible at the site of the infection, indicating the body’s attempt to combat the invading bacteria.

Being aware of these symptoms is paramount. If any of these signs are evident post wisdom tooth emergence or extraction, seeking dental advice immediately is essential to ensure appropriate care and treatment.

What to do if gum is infected after wisdom teeth removal


Experiencing complications after wisdom teeth removal, such as a gum infection, is a concern for many. Since wisdom tooth extraction is a common dental procedure, understanding the proper steps to address potential post-operative infections is vital for optimal recovery and oral health.

Immediate Actions:

  1. Pain Awareness: Monitor for persistent or increasing pain after the initial discomfort from the wisdom tooth removal subsides. This could indicate an infection or complications like a dry socket.
  2. Swelling and Fever: Swelling around the extraction site or a fever can signal an infection. If these symptoms arise, it’s crucial to address them promptly.
  3. Examine the Socket: Ensure the tooth socket is free from food debris, which can cause infections. A clean socket promotes better healing.
  4. Bad Breath and Nasty Taste in Your Mouth: A persistent bad taste or bad breath, despite maintaining oral hygiene, could indicate an infection.

Preventative Measures:

  1. Oral Hygiene: Maintain a meticulous oral hygiene regimen, but be gentle around the extraction site to avoid disrupting the healing process.
  2. Avoid Smoking: Smoking post-tooth removal can increase the risk of complications, including dry sockets and infections.
  3. Follow Post-Operative Instructions: Strictly adhere to the dentist’s post-operative care guidelines, including taking prescribed antibiotics if given.

Causes of wisdom tooth infection

The emergence of wisdom teeth, often in the late teens, adolescence, or early adulthood, can be a rite of passage for many. While they’re a natural part of our dental development, these third molars can sometimes lead to complications, including infection. Understanding the causes behind these infections is crucial, as it can aid in prevention and ensure prompt and appropriate treatment if they do arise.

Impacted Wisdom Teeth:

One of the most common causes of wisdom tooth infections is impaction. This occurs when the mouth has insufficient space for the tooth to emerge properly. As a result, the tooth might only partially emerge or grow at an angle, pushing against the adjacent tooth. This can create pockets where bacteria can easily thrive, leading to infection.

Gum Flaps:

A wisdom tooth partially breaks through the gum’s surface, which can form a gum flap. This flap can act as a trap for food particles and bacteria. Over time, this can become a breeding ground for bacteria if not cleaned properly, leading to pericoronitis, a painful gum infection.


Due to their location at the back of the mouth, wisdom teeth can be challenging to clean properly. This can make them more susceptible to decay. Bacteria from decaying teeth can easily spread, causing an infection.

Gum Disease:

Inadequate oral hygiene can lead to gum diseases like gingivitis. If left untreated, this can progress to more severe forms of gum disease, which can then spread to the area around a wisdom tooth, resulting in an infection.

Cyst Formation:

Sometimes, a cyst can form around a wisdom tooth that hasn’t broken through the gum. While cysts aren’t always problematic initially, they can become infected over time if they fill with fluid and bacteria.

Compromised Immune System:

Individuals with weakened immune systems, whether due to underlying health conditions or medications, might be at a higher risk for infections, including those associated with wisdom teeth.

In summary, wisdom teeth are a natural part of our dental makeup but come with potential issues, including infections. Understanding the causes of affected teeth and maintaining good oral health practices can significantly reduce the risks associated with these third molars.

Wisdom tooth infection complications

Wisdom teeth, also known as third molars, are the last to emerge, typically appearing in late adolescence or early adulthood. While their emergence is a natural part of dental development, for many individuals, they come with a host of potential complications. One of the most concerning issues associated with wisdom teeth is infection. Understanding the implications of wisdom tooth infections is crucial, as neglecting or overlooking the signs can lead to severe and, in some cases, life-threatening complications.

1. Pericoronitis

  • Definition: Pericoronitis is one of the most common complications of a partially erupted wisdom tooth. This condition arises when the gum tissue surrounding the emerging tooth becomes inflamed and infected.
  • Symptoms: These may include pain, swelling, a bad taste in the mouth, and difficulty in opening the jaw.
  • Risks: If not promptly treated, the infection can spread to the cheek, throat, or neck areas.

2. Abscess Formation

  • Definition: An abscess refers to a pocket of pus that develops around the infected tooth. It results from the body’s attempt to contain and combat the bacterial infection.
  • Symptoms: Pain, swelling, and redness in the affected area are common indicators of an abscess. Patients might also develop fever due to the body’s response to infection.
  • Risks: An untreated dental abscess can lead to the spread of infection into the bloodstream, which is a condition known as sepsis—a life-threatening complication.

3. Jaw Stiffness and Pain

  • Definition: Infections associated with wisdom teeth can cause tightness and discomfort in the jaw muscles, making it difficult for the individual to open their mouth or chew properly.
  • Symptoms: Limited jaw movement, pain while chewing, or tenderness in the jawline.
  • Risks: Chronic pain and discomfort can impact daily life and may indicate a more severe underlying issue requiring intervention.

4. Cyst Formation

  • Definition: Sometimes, an untreated wisdom tooth can lead to the formation of a cyst around the tooth’s root. If not addressed, This fluid-filled sac can destroy bone, roots of adjacent teeth, and even the jawbone itself.
  • Symptoms: A feeling of pressure, discomfort, or swelling in the affected area. It may not always be painful but can cause damage silently over time.
  • Risks: If a cyst is left untreated, it can become a tumor, necessitating surgical intervention, and potentially more complex treatments.

In conclusion, while wisdom teeth emerge naturally, the potential for complications, particularly infections, should not be taken lightly. Regular dental check-ups and being attuned to the signs and symptoms of complications can prevent more severe health issues and ensure the overall well-being of other teeth in an individual. If you suspect any issues with your wisdom teeth, it’s essential to consult a dental professional promptly.

How long do you have to worry about infection after wisdom teeth removal?

After wisdom teeth removal, the risk of infection is highest within the first two weeks. During this period, it’s vital to follow post-operative instructions from the oral surgeon or dentist to minimize this risk. While the initial healing phase is typically complete after a few weeks, the deeper tissues may take up to a few months to fully heal.

It’s essential to maintain oral hygiene and observe any signs of infection, such as persistent pain, swelling, pus discharge, or fever, especially during the initial weeks after the procedure. If any of these symptoms occur, it’s crucial to contact your dental professional immediately.

What does an infected socket look like?

A dental extraction, while routine, comes with its set of post-operative concerns. One of the most significant worries is the development of an infected socket, known medically as “alveolar osteitis” or “dry socket.” Identifying and treating an infected socket early on is paramount for timely treatment and preventing prolonged discomfort. Here’s what an infected socket typically looks like:

  1. Loss of Protective Blood Clot: An essential part of the healing process is the formation of a blood clot in the socket. If this clot is prematurely lost or never forms, the socket may appear empty with exposed bone, making it vulnerable to infection.
  2. Unpleasant Odor and Taste: An infected socket often exudes a foul smell and can leave a persistent bad taste in the mouth, signaling bacterial activity.
  3. Pain and Discomfort: While some pain is expected after an extraction, an infected socket results in intense, throbbing pain that can radiate to the ear or neck. The pain typically escalates instead of improving a few days post-extraction.
  4. Swelling and Redness: The surrounding gum area may become inflamed, appearing red and swollen, indicating an active infection.
  5. Pus Formation: In some cases, there might be visible pus or discharge in the socket, a clear sign of infection.

In conclusion, recognizing the signs of an infected socket is crucial for anyone who has undergone a dental extraction. If any of these symptoms are observed, seeking immediate attention from a dental professional is essential to ensure a smooth and healthy recovery.


In wrapping up, it’s evident that recognizing and addressing an infected gum after wisdom tooth removal is crucial for a seamless recovery and overall oral health. Neglecting the signs can lead to prolonged discomfort and more serious complications. Staying informed and vigilant and seeking prompt dental intervention at the first hint of infection ensures that patients can avoid further complications and enjoy a healthy smile. Remember, an ounce of prevention is worth a pound of cure, especially regarding our oral health.
