Should You Take Antibiotics After Wisdom Tooth Surgery? New Data from Australia

by

If you’re preparing for wisdom tooth surgery, you might assume that a round of antibiotics is just part of the process. For years, many dentists prescribed them “just in case” to prevent infection. However, a major 5-year study from Griffith University in Australia, published in 2025, suggests that for most people, antibiotics are unnecessary. The study followed over 1,500 patients and nearly 3,000 extractions to see how often infections actually occur and what really causes them. Here’s the breakdown of what they found. The Big Number: 1.03% The most significant finding of the study was the infection rate. Out of all the surgical extractions performed, the post-operative infection (POI) rate was only 1.03%. To put that in perspective, worldwide studies often report infection rates anywhere from 1% to 30%. The researchers at Griffith University found that true infections—characterized by pus, … Read more

Invasive dental procedures linked to heart inflammation

by

An interesting study titled “Endocarditis, invasive dental procedures, and antibiotic prophylaxis efficacy in US Medicaid patients” appears in Oral Diseases on April 27, 2023, written by Martin Thornhill and et. al. The study investigates the association between invasive dental procedures and endocarditis, which is inflammation of the inside lining of the heart chambers and heart valves. In the study the authors used the MarketScan multi-state Medicaid database to examine 1.68 million Medicaid patients with linked medical, dental, and prescription data and compared it to 7.95 million individuals with employer-provided Commercial/Medicare-Supplemental health coverage with linked dental and prescription benefits. The authors found that the cohort study showed increased endocarditis incidence within 30 days of invasive dental procedures in those at high risk, particularly after extractions or oral surgery. It was also determined that antibiotic prophylaxis significantly reduced endocarditis incidence following invasive … Read more

NIH awards grant to study responsible antibiotic use

by

The National Institutes of Health (NIH) has awarded the University of Texas Health Science Center at San Antonio a four-year, $2.4 million grant to work with the American Dental Association Science & Research Institute (ADASRI) to perform a clinical trial study for the responsible use of antibiotics to treat periodontal disease also known as gum disease. The study will allow for the generatation of real-world data on periodontal disease treatments that are supplemented by antibiotics. The study will be lead by principle investigator Georgios Kotsakis, DDS, MS who is an associate professor of periodontics at the UT Health San Antonio School of Dentistry. More than 30 clinicians who belong to the National Dental Practice-Based Research Network (PBRN) will collect data for the study. The trial is expected to start in Spring 2023 and the periodontal patients will be treated and … Read more

Lemierre’s Syndrome after Wisdom Teeth Removal

by

An interesting article titled “Lemierre’s Syndrome Following Extraction of Wisdom Teeth,” appears in the October 20, 2020 edition of the Cureus Journal of Medical Science (written by A. Keshary and M. Hagan, 12(10): e11061). The article describes a case of an 18 year old man who had his wisdom teeth extracted and then developed Lemierre’s Syndrome which rarely occurs after wisdom tooth removal but is is known to affect young and healthy adults; See Near Death Wisdom Teeth Removal Experience where another case has been discussed on this site in the past. Lemierre’s syndrome is a serious bloodstream infection typically caused by Fusobacterium necrophorum. It has a death rate of around 18% and thus if detected needs to be quickly treated with antibiotics. Very few cases of Lemierre’s syndrome after wisdom teeth surgery have occurred since antibiotics became readily available. In the … Read more

Wisdom Tooth Extraction Leads to Giant Lung Abscess

by

A unique complication of wisdom teeth removal is described in the article titled “A 45-Year-Old Man With Acute Chest Pain, Fever, and Dyspnea After Tooth Extraction” appearing in the December 2021 edition of Chest written by Tashiro et al. (issue 160, no. 6, pp. e623 – e628). In the article, discussion is made of a healthy 45-year-old man who experienced respiratory failure due to a giant lung abscess that formed as a result of oral bacteria after a wisdom tooth extraction. Two days after having a wisdom tooth removed, the 45-year-old man in Japan developed chest pain on his right side. Two weeks after the wisdom tooth extraction, the man went to a hospital because he had a fever, difficulty breathing, and had a cough and purulent sputum. The man was in good health and visited a dentist twice a … Read more
