antibiotics for wisdom tooth infection | Important Points

Wisdom teeth are the last set of molars to develop, usually in the late teenage years or early twenties. These teeth are located at the back of the mouth and can cause a lot of trouble if they become infected or impacted. One of the most common complications associated with wisdom teeth is an infection. When an infection occurs, antibiotics may be prescribed as part of the treatment plan. In this article, we’ll take a closer look at antibiotics for wisdom tooth infections.

What is a Wisdom Tooth Infection?

A wisdom tooth infection occurs when bacteria get into the soft tissue surrounding the tooth or into the tooth itself. This can cause swelling, pain, pus, and fever. It’s important to seek treatment for a wisdom tooth infection as soon as possible to prevent the infection from spreading to other parts of the body.

Antibiotics for Wisdom Tooth Infections

Antibiotics are often prescribed for wisdom tooth infections as part of the treatment plan. These medications are designed to kill the bacteria causing the infection and to prevent the infection from spreading. But not all wisdom tooth infections require antibiotics.

In some cases, the infection may be mild and can be treated with home remedies like warm saltwater rinses or over-the-counter pain relievers. However, if the infection is severe, or if it has spread to other parts of the body, antibiotics may be necessary.

Types of Antibiotics Used for Wisdom Tooth Infections

There are several different types of antibiotics that may be prescribed for a wisdom tooth infection. The type of antibiotic prescribed will depend on the type of bacteria causing the infection, as well as the severity of the infection. Some of the most commonly prescribed antibiotics for wisdom tooth infections include:

1. Penicillin: This is one of the most common antibiotics used for dental infections. It’s effective against most types of bacteria that cause oral infections, including streptococci and staphylococci.

2. Amoxicillin: This is another widely used antibiotic for dental infections. It’s similar to penicillin in its effectiveness and is also good for treating oral infections caused by streptococci and staphylococci.

3. Metronidazole: This antibiotic is used to treat infections caused by anaerobic bacteria, which are bacteria that don’t need oxygen to survive. It’s often used in combination with other antibiotics to treat severe infections.

4. Clindamycin: This antibiotic is used to treat infections caused by bacteria that are resistant to other antibiotics. It’s often prescribed for severe or chronic infections.

5. Azithromycin: This antibiotic is used to treat a wide range of bacterial infections, including dental infections. It’s often prescribed for people who are allergic to other types of antibiotics.

How Long Should Antibiotics be Taken for Wisdom Tooth Infections?

The length of time that antibiotics should be taken for a wisdom tooth infection depends on the severity of the infection and the type of antibiotic prescribed. In most cases, antibiotics are prescribed for a period of 7-10 days. It’s important to take the entire course of antibiotics as prescribed, even if you start feeling better before the medication is finished.

If you stop taking antibiotics before the full course is completed, the bacteria causing the infection may not be completely eradicated. This can lead to a recurrence of the infection, which may be more difficult to treat the second time around.

Potential Side Effects of Antibiotics

While antibiotics can be very effective in treating wisdom tooth infections, they can also have side effects. Some of the most common side effects of antibiotics include:

1. Diarrhea: Antibiotics can disrupt the natural balance of bacteria in the gut, leading to diarrhea.

2. Nausea: Some people may experience nausea or vomiting while taking antibiotics.

3. Allergic reactions: In rare cases, people may develop an allergic reaction to antibiotics. Symptoms of an allergic reaction can include rash, hives, and difficulty breathing.

4. Yeast infections: Antibiotics can also disrupt the balance of bacteria in the mouth or vagina, leading to a fungal infection.


Antibiotics can be helpful in treating wisdom tooth infections, but they should only be prescribed by a qualified healthcare professional. It’s important to take the entire course of antibiotics as prescribed to ensure that the infection is completely eradicated. If you have any concerns or questions about antibiotics or wisdom tooth infections, be sure to speak with your dentist or doctor.
