Which Antibiotics Can I Take For Tooth Infection ?

Tooth infection or abscessed tooth are common dental problems caused by tooth decay, bacterial infections, injuries to dental tissues, or as a result of certain dental procedures. Tooth infections or abscesses can cause severe pain, sensitivity, and intra or extraoral swellings. If left untreated, dental infections can spread to adjacent tissues increasing the severity of the dental problem.

In case you have a tooth infection or any signs of infected oral tissues, it is important to see your dentist as soon as possible. At Channel Islands Family Dental Office, dentists in Ventura, Oxnard, Santa Paula and Port Hueneme, our dental professionals always suggest the patients follow their regular check-ups for early detection of any signs of tooth infections or decay. In case of tooth infection, your dentist is likely to prescribe antibiotics to help with the bacterial infections. Let’s understand some more about the commonly used antibiotics in dental infections:

The type of antibiotic prescribed depends upon the nature of the microbe causing the infection. Different classes of antibiotics have been found effective in attacking the bacteria in different ways.

Antibiotics For Tooth Infection

  1. Penicillin antibiotics for tooth infections: This is the most common type of antibiotic used in dental infections which include amoxicillin and penicillin to name a few. Due to the increasing resistance of bacteria to antibiotics, they have been combined with clavulanic acid to boost the effectiveness of amoxicillin. Some people might be allergic to this class of antibiotics, thus it is important to discuss your medication history and allergies with your dentist. This will help your dentist to choose a different antibiotic that will help you the best. A typical dose of amoxicillin for a dental infection is either 500 mg every 8 hours or 1,000 mg every 12 hours. Typical dosages of amoxicillin with clavulanic acid are around 500–2,000 mg every 8 hours or 2,000 mg every 12 hours.
  2. Clindamycin: It is widely used to treat a wide variety of bacterial infections. It is considered an effective option due to its low cost, availability as well as low bacterial resistance, especially in comparison to penicillin. A typical dose of clindamycin is either 300 mg or 600 mg every 8 hours.
  3. Metronidazole: It is typically advised in a tooth with anaerobic bacterial infections. However, one should avoid any kind of sedative or alcohol-containing products while using antibiotics. The dosage for metronidazole is around 500–750 mg every 8 hours.
  4. Azithromycin: It works well against a wide variety of bacterial infections of dental tissues. they are usually recommended to patients allergic to the penicillin class of drugs or to patients who do not respond to other drugs such as clindamycin. A typical dose of azithromycin is 500 mg every 24 hours for 3 days.


It is common to prescribe probiotics along with antibiotics in dental infections to maintain healthy gut flora. The antibiotic helps in reducing the infection and helps with the problem but they are not the complete solution. Even if antibiotics work and reduce the infection, it’s still important to get the required dental work to prevent recurring infections.

It is not advisable to overlook the signs and symptoms of any persistent pain and infection. We, at Channel Islandsfamily Dental Office, dentist in Ventura, Oxnard, Santa Paula, and Port Hueneme thoroughly examine the patient; take required X-rays to determine the cause of infection and to plan the course of treatment.
