Wisdom teeth, also known as third molars, are the last set of teeth that typically emerge during a person’s late teens or early twenties. For some, wisdom teeth come in without complications, but for many others, these teeth can cause a range of issues, including pain, infection, and misalignment. One of the most common complications associated with wisdom teeth is gum infection. In this article, we will explore how wisdom teeth can cause gum infections, the symptoms of these infections, and the available treatment options.
What Are Wisdom Teeth?
Wisdom teeth are the third molars located at the back of the mouth. They are the last teeth to emerge, usually around the ages of 17 to 25. For some people, these teeth come in normally, without causing any issues. However, for others, wisdom teeth may become impacted, meaning they do not emerge properly through the gums or do not have enough space to grow.
When wisdom teeth are unable to fully erupt or grow in the correct position, they can lead to various dental problems. These include pain, crowding of other teeth, and gum infections.
How Do Wisdom Teeth Cause Gum Infections?
Wisdom teeth can cause gum infections in a variety of ways. One of the most common ways is when they become partially impacted. This means that part of the tooth emerges through the gums, but the rest is trapped beneath the gum line. This creates an opening where bacteria can enter, leading to infection.
Partially Erupted Wisdom Teeth
When wisdom teeth are only partially erupted, they can trap food particles and plaque around the area where the tooth has partially emerged. The gum tissue around the partially erupted tooth may become irritated, leading to swelling, redness, and tenderness. Over time, this can increase the risk of gum infection.
Pericoronitis: An Infection Around the Tooth
A specific type of gum infection that is often caused by partially erupted wisdom teeth is known as pericoronitis. This infection occurs when bacteria accumulate around the gum tissue that partially covers the tooth. The gum flap can trap food and bacteria, creating an environment where infection is more likely to occur.
The symptoms of pericoronitis include swollen gums, pain, difficulty opening the mouth, and an unpleasant taste in the mouth. In some cases, the infection can spread to nearby areas of the mouth, causing further complications.
Impacted Wisdom Teeth and Their Effect on Surrounding Tissue
When wisdom teeth are fully impacted, meaning they are completely trapped beneath the gum tissue and bone, they can also cause gum infections. Impacted teeth can exert pressure on adjacent teeth and the surrounding gum tissue. This can lead to gum swelling, irritation, and pain. The inability of the tooth to fully emerge creates an environment where bacteria can grow, leading to infection.
Infection Spread to Adjacent Teeth
Sometimes, the infection caused by impacted wisdom teeth can spread to the adjacent teeth. When a wisdom tooth becomes infected, the bacteria can travel to nearby molars, leading to further damage and even tooth decay. The spread of infection to adjacent teeth can worsen the overall dental condition and complicate the treatment process.
Signs and Symptoms of a Gum Infection Caused by Wisdom Teeth
If you suspect that your wisdom teeth might be causing a gum infection, it’s important to recognize the signs and symptoms early. The following symptoms may indicate that a gum infection is present:
Pain and Discomfort
Pain is one of the most common symptoms of a gum infection caused by wisdom teeth. You may experience pain in the back of your mouth, near where the wisdom teeth are located. This pain may be constant or may worsen when chewing, brushing, or even speaking. The pain can sometimes radiate to the jaw, ears, or neck.
Swelling and Redness of the Gums
If your wisdom teeth are causing a gum infection, the affected area around the tooth may appear swollen and red. The gums may feel tender to the touch, and the swelling may be noticeable near the back of your mouth, where the wisdom teeth are located. The swelling may also cause the gum tissue to feel soft or puffy.
Difficulty Opening the Mouth
Infections caused by wisdom teeth can make it difficult to open the mouth fully. This happens because the swollen gum tissue may obstruct the normal range of motion. If the infection spreads or becomes severe, you may experience difficulty eating, speaking, or even swallowing.
Unpleasant Taste or Odor in the Mouth
An unpleasant taste or odor in the mouth can occur when bacteria build up around the wisdom teeth. This is especially common in cases of pericoronitis. If food particles become trapped around the gum flap that partially covers the wisdom tooth, bacteria can produce foul-smelling compounds that result in a bad taste or odor.
Fever and General Discomfort
In some cases, a gum infection caused by wisdom teeth can lead to more severe symptoms such as fever, chills, and a general feeling of illness. These symptoms occur when the body tries to fight the infection. If you experience fever, it is important to seek medical attention promptly.
How Is a Gum Infection Treated?
If you are diagnosed with a gum infection caused by your wisdom teeth, your dentist or oral surgeon will recommend an appropriate treatment plan based on the severity of the infection. Treatment options can vary depending on whether the infection is mild or more serious.
Antibiotics for Infection Control
For mild infections, a dentist may prescribe antibiotics to help clear the infection. Antibiotics are typically used to kill the bacteria causing the infection and to reduce inflammation. You may be instructed to take the antibiotics for several days until the infection begins to subside.
Professional Cleaning and Irrigation
In cases of pericoronitis, the dentist may clean and irrigate the affected area to remove food particles and bacteria trapped around the partially erupted wisdom tooth. This cleaning process can help alleviate the infection and reduce inflammation in the gums.
Surgical Removal of the Wisdom Teeth
If the infection is recurrent or severe, the dentist may recommend surgical removal of the wisdom teeth. Wisdom teeth extraction is often the most effective way to prevent further gum infections and resolve the underlying issue. The procedure may be done under local anesthesia or sedation, depending on the complexity of the case.
Gum Care and Pain Management
In addition to antibiotics and cleaning, pain management may be necessary to help alleviate discomfort during the healing process. Your dentist may recommend over-the-counter pain medications such as ibuprofen or acetaminophen to help reduce pain and swelling. Warm saltwater rinses can also be used to soothe irritated gums.
Preventing Gum Infections from Wisdom Teeth
While it may not always be possible to prevent wisdom teeth from becoming impacted, there are several steps you can take to reduce the risk of gum infections:
Good Oral Hygiene
Maintaining good oral hygiene is essential for preventing infections. Brush your teeth twice a day, floss regularly, and use mouthwash to remove bacteria and plaque. Paying special attention to the area around your wisdom teeth can help prevent the accumulation of food particles and bacteria.
Regular Dental Checkups
Regular visits to your dentist are important for monitoring the health of your wisdom teeth. Your dentist can check for any signs of impaction or infection and provide early treatment if necessary. X-rays may be taken to assess the positioning of the wisdom teeth and identify potential problems before they become more serious.
Early Removal of Wisdom Teeth
If your wisdom teeth are not yet impacted, your dentist may recommend early removal to avoid future complications. By removing the wisdom teeth before they become problematic, you can reduce the risk of gum infections and other dental issues.
Conclusion
Wisdom teeth can indeed cause gum infections, particularly if they are impacted or partially erupted. Infections such as pericoronitis can lead to pain, swelling, and other uncomfortable symptoms. If you experience signs of a gum infection, it is essential to seek treatment promptly. With proper care, antibiotics, and, in some cases, surgical removal of the wisdom teeth, most infections can be treated effectively. If you have concerns about your wisdom teeth, speak with your dentist or oral surgeon to determine the best course of action for your oral health.
