From the Guidelines
The appropriate management for odontogenic infections without noticeable gum redness typically involves prompt dental evaluation, mechanical intervention, and possibly antibiotics, with a focus on addressing the underlying cause and preventing potential complications. A dentist should examine the area to identify the source of infection, which may require dental X-rays to detect abscesses or bone involvement, as highlighted in the 2013 guide to utilization of the microbiology laboratory for diagnosis of infectious diseases 1. The primary treatment is addressing the underlying cause through procedures such as root canal therapy, tooth extraction, or incision and drainage of any abscess.
According to the most recent guidelines on essential medicines and aware: recommendations on first- and second-choice antibiotics for empiric treatment of clinical infections, published in 2024 1, the use of antibiotics should be judicious and based on specific patient groups, such as those with systemic involvement or progressive infections. For example, the European Society of Endodontology recommends adjunctive antibiotics in specific patients' groups, with phenoxymethylpenicillin as the first choice.
Some key points to consider in the management of odontogenic infections without noticeable gum redness include:
- Prompt dental evaluation to identify the source of infection
- Mechanical intervention, such as root canal therapy or tooth extraction, to address the underlying cause
- Possible use of antibiotics, with amoxicillin or clindamycin as potential options, depending on patient factors and antibiotic susceptibility
- Pain management with acetaminophen or ibuprofen
- Warm salt water rinses to reduce bacterial load
- Monitoring for potential complications, such as Ludwig's angina or cavernous sinus thrombosis, even in the absence of visible gum inflammation.
It is essential to note that the absence of gum redness does not rule out infection, as the infection may be contained within the tooth or bone, emphasizing the need for thorough dental evaluation and appropriate management to prevent morbidity, mortality, and impact on quality of life.

From the Research
Etiology of Odontogenic Infections
- Odontogenic infections are serious and potentially life-threatening conditions that originate from dental infections, with dental caries, gingivitis, and periodontitis being the most common causes 2.
- These infections can spread to vital and deep structures, especially in diabetic, immunocompromised, or weakened patients, and may prove fatal 3.
Clinical Presentation
- Patients with odontogenic infections often present with pain and swelling, and may also exhibit trismus (44% of cases) and dysphagia (over 70% of cases) 4, 5.
- The absence of noticeable gum redness does not rule out the presence of an odontogenic infection, as the infection can spread to deeper tissues without causing visible inflammation.
Management of Odontogenic Infections
- The management of odontogenic infections is primarily surgical, with extraction, surgical drainage, and high-dose intravenous antibiotics being the mainstay of treatment 4, 5.
- Antibiotics such as amoxicillin/clavulanic acid and clindamycin are commonly used to treat odontogenic infections, with amoxicillin/clavulanic acid being comparable to clindamycin in achieving clinical success 6.
- The choice of antibiotic should be guided by the severity of the infection, the presence of any underlying medical conditions, and the potential for antibiotic resistance 5.
Importance of Prompt Treatment
- Prompt treatment of odontogenic infections is crucial to prevent the spread of infection to vital and deep structures, and to reduce the risk of complications and mortality 4, 3.
- Airway maintenance and surgical decompression under adequate antibiotic coverage are critical components of the management of severe odontogenic infections 3.
