- Pain ± swelling in the head and neck region with odontogenic (teeth and supporting structures) origin of infection; if left untreated, can lead to serious and potentially life-threatening illnesses
- Assume any head and neck infection or swelling to be odontogenic in origin until proven otherwise.
- Antibiotics should be prescribed as an adjunct to proper dental intervention. Antibiotics should be prescribed for acute infections for 3 to 7 days.
- Ginigivitis and periodontal disease may be treated with oral antibiotics. Soft tissue infections may require IV antibiotic treatment.
- Overall incidence for children was ~47%.
- Rates of untreated dental caries are highest in Latino and non-Latino black individuals below the poverty line (up to 58%).
- Rates decrease with increases in socioeconomic status.
- Dental caries represent the most common chronic disease worldwide.
- Prevalence of total caries ~46%; prevalence of untreated caries is ~13%.
- 21–53% of youth are affected with rates increasing with age. 9–13% have untreated dental caries.
- 26% of individuals aged >20 years have untreated dental caries (1).
- 90% of adults 20 to 64 years have had dental caries in their permanent teeth.
Etiology and Pathophysiology
- More than 90% of all head and neck infections have an odontogenic origin.
- Caries or trauma can lead to death of the tooth pulp, which can lead to infection and/or abscess of adjacent tissues via direct or hematogenous bacterial colonization.
- Caries (tooth decay; “cavity”) represent a contagious bacterial infection causing demineralization and destruction of the tooth tissue (enamel, dentin, and cementum).
- Streptococcus mutans is easily transmitted to newly dentate infants by caregivers.
- Acidic secretions from S. mutans are implicated in early caries.
- Typical oral microbiome includes numerous aerobic and anaerobic bacteria. The most common pathologic aerobic bacteria is Streptococcus spp.
- Anaerobic bacteria are more common with infections near the tooth base (2).
- Low socioeconomic status
- Parent and/or sibling with history of caries or existing untreated dental caries (especially in past 12 months)
- Previous dental caries
- Poor access to dental/health care; lack of dental insurance; fear of dentist
- Poor oral hygiene; poor nutrition, including diet containing high level of sugary foods and drinks
- Trauma to the teeth or jaw
- Inadequate access to and use of fluoride
- Gingival recession (increased risk of root caries)
- Physical and mental disabilities
- Poorly controlled systemic diseases (e.g., diabetes)
- Decreased salivary flow (e.g., use of anticholinergic medications, immunologic diseases, radiation therapy to head and neck)
- Most dental problems can be avoided through flossing/use of interdental brushes; brushing with fluoride toothpaste, systemic fluoride (fluoridated bottled water; fluoride supplements for high-risk patients and in non-fluoridated areas); fluoride varnish for all children aged <6 years and moderate- to high-risk patients; regular dental cleanings (1),(2)[B]
- Prevent transmission of S. mutans from mother/caregiver to infant by improving maternal dentition, chlorhexidine gluconate rinses, and use of xylitol products for mother especially during the first 2 years of a child’s life. Avoid smoking, which is linked to severe periodontal disease.
- Good control of systemic diseases (e.g., diabetes) and changes in lifestyle (e.g., smoking cessation)
- Fluoride varnish provided by dental or medical primary care providers twice per year
Commonly Associated Conditions
- Extensive caries, crowding, multiple missing teeth
- Periapical and periodontal abscess
- Soft tissue cellulitis
- Periodontitis (deep inflammation ± infection of gingiva, alveolar bone support, and ligaments)
