Risk factors shared by adults & children include:
- High bacterial counts
- Family history of caries
- Frequent consumption of sugar-containing foods and beverages
- Inadequate fluoride
- Poor oral hygiene practices and behaviors
- Low socioeconomic status
In addition, adult caries is accelerated by the burdens of the aging process, disease, and treatments.
Physical Disabilities
- Make brushing and other oral hygiene activities more difficult
Existing Restorations or Appliances
- Markers for previous caries and a risk factor for future caries
- Appliances can trap food and plaque
- Most likely site of caries in an adult
Decreased Salivary Flow
- Caused by disease or medication
- Xerostomia (dry mouth) places a patient at much higher caries risk
Medications
- Increase caries risk by:
- Decreasing saliva flow
- High levels of sucrose
- Sweetened medications such as syrups may increase sugar exposure
