Wisdom Teeth Infection After Removal | Signs | Treatment

Wisdom tooth removal is a widespread dental procedure. In America alone, 10 million wisdom teeth are removed every year. The wisdom tooth is another term for the third molar, the last tooth at each end of both jaws. Sometimes, patients face wisdom teeth infection after removal. This article will discuss wisdom tooth extraction infection, its signs, and treatment. 

What are Wisdom Teeth?

Wisdom teeth are the posterior-most molars, which erupt in the late teens to early twenties. Humans do not require wisdom teeth to perform normal oral functions. Chewing and speech functions can be carried well even without these teeth. 

Then why do we have wisdom teeth in our mouths? 

We have these because our ancestors required these teeth for chewing and eating raw food. They do not erupt in every person’s mouth. In addition, wisdom teeth do not erupt in childhood as well.

Wisdom Tooth Extraction

These teeth are not required in the mouth, so they are mainly extracted if they present an issue. There are certain conditions in which it is recommended to remove the wisdom tooth. 

These conditions include:

  • Pain
  • Swollen gums due to accumulation of food debris and bacteria
  • Impacted wisdom tooth
  • The wisdom tooth is present within the jawbone at the wrong angle, so it can not erupt freely.
  • Difficulty in cleaning around the tooth as it is difficult to approach the end of the mouth with a toothbrush. Due to lack of cleaning, a pocket is developing, which is unhealthy.
  • The wisdom tooth has a cavity in it.
  • An abscess, cyst, or infection is associated with it. 

In such situations, it is preferred to remove the wisdom tooth. Despite recurrent treatment, the issues arise again.

Wisdom Teeth Infection After Removal

It is not uncommon to experience wisdom teeth infection after removal. The extraction is a curative treatment. Due to the following reasons, wisdom teeth infections are prevalent after extraction:

Poor Oral Hygiene

A lack of oral hygiene maintenance is one of the most common causes of wisdom teeth infection after removal. Failure to maintain proper oral hygiene can result in the accumulation of bacteria, remnants of food, and plaque, which can easily cause an infection at the extraction site. 

To reduce this risk, dentists suggest lightly brushing your teeth, including the extraction site, after the first 24 hours after surgery and using a soft brush to avoid dislodging the blood clot.

Dry Socket

The feeling of pain that does not go away no matter which painkiller you take is a sign of wisdom teeth infection after removal. A dry socket is also known as “Alveolar osteitis.” In this condition, the clot has been dislodged, and the underlying bone is exposed along with nerves. 

As a result of which, the patient experiences unbearable pain. The use of straw or any other hard eatable can dislodge the clot. A gel, commonly known as the “Alveogel,” is applied, and the dentist does a dressing. This has to be done for 3-5 days consecutively. The contents of this gel relieve the pain. 

Attack of Bacteria

There is a possibility that the wisdom tooth was extracted due to an infection. In such cases, the bacteria can invade the surgical site and cause an infection. Therefore, to avoid it, the dentist may prescribe an antibiotic and painkillers to prevent possible bacterial infections. 

Signs of Infection After Wisdom Teeth Removal

There are sure signs which indicate wisdom teeth infection after removal. If you observe these signs on time and consult the dentist, a timely treatment can be performed. 

The signs include:

  • Difficulty in breathing
  • Difficulty in chewing and swallowing your food. 
  • Excessive bleeding has occurred at the surgical site. 
  • Swollen and infected gums after wisdom teeth removal
  • A bad breath or altered taste in your mouth does not go away despite rinsing with salt water, brushing, and flossing. 
  • The feeling of numbness has persisted for more than 24 hours since the wisdom tooth removal. 
  • Pus is forming in the extraction site.
  • It’s painful to open and close your mouth. 
  • The pain is intolerable. The gums, extraction site, and teeth ache despite taking painkillers.
  • You have a high fever within a week of the procedure. 
  • Your nose discharges blood or pus. 
  • Body aches, fever, malaise, and fatigue. 

Wisdom Tooth Removal Infection Treatment

A wide range of treatments is available for wisdom teeth infection after removal. The exact treatment depends on the cause and nature of the disease. 

The dentist may suggest one or more of the following treatments:


The dentist may prescribe antibiotics to treat and stop the infection from spreading. It would help if you took the antibiotics as directed by your dentist. Even if your symptoms subside before the course of antibiotics is complete, you should still complete it. Moreover, never consume medication without consent and advice from the doctor, nor discontinue it. 


Paracetamol, acetaminophen, and ibuprofen are common painkillers effective for wisdom teeth infections after removal. Moreover, other medicines, like naproxen, can be effective too. However, you should follow your dentist’s instructions as they recommend the medicine depending on your health conditions. 

Lukewarm Salt Water Gargles and Rinses

This can be considered as a home remedy. It is antiseptic and has proven beneficial for wisdom teeth infection after removal. Rinsing your mouth with warm salt water can help reduce inflammation and boost the process of healing. 


Mix half a teaspoon of salt in half a glass of warm water, then gently swish the solution in your mouth for about 30 seconds. Repeat a couple of times per day, especially after meals.

Drainage of Abscess and Surgical Debridement

This is one of the worst-case scenarios in which an abscess develops after wisdom tooth extraction. In such a case, antibiotics and painkillers are started if the abscess is accompanied by fever and body aches. 

After that, the abscess is drained under anesthesia to reduce the discomfort for the patient. This is followed by thoroughly cleaning and removing dead content and debris from the extraction site. The patient should visit the dentist for follow-up appointments.
